Oxygen status is commonly monitored noninvasively by peripheral saturation monitoring (SpO 2). However, the risk of hyperoxia above specific SpO 2 levels in critically ill patients is unknown. The purpose of this study was to determine a threshold value of SpO 2 above which the prevalence of arterial hyperoxia distinctly increases.
Oxygen is drawn into the body from the atmosphere by breathing. Each lung is inundated by an estimate of 300 million alveoli, which are cocooned by numerous blood capillaries. Alveolar walls and capillary walls are extremely thin, this makes them permeable, therefore, oxygen passing into the alveoli immediately diffuses into the blood capillaries – the process takes up only .25 seconds in an adult at rest. The bulk of oxygen that diffuses into the blood binds itself to hemoglobin molecules that are found in red blood cells creating oxyhemoglobin. The smaller bulk of the oxygen that is left over dissolves into the blood plasma. Blood that is rich in oxygen (arterial blood) then flows through pulmonary veins, into the left atrium and left ventricle, and finally circulates throughout the entire body’s organs and their cells.
Carbon Dioxide, which is a byproduct of cell metabolism, dissolves in the blood and is circulated back to the lungs where it is released as fresh oxygen attaches itself to hemoglobin and the cycle is replicated and repeated over and over again. The total amount of oxygen that is transported around the body is shaped by many factors: the lung factor which is the degree to which hemoglobin binds to oxygen, the anemic factor which is the hemoglobin concentration and the cardiac factor which is essentially the cardiac output. Oxygen saturation levels are an indicator of oxygen transportation in the body and point to whether oxygen is being supplied to the body, especially to the lungs in sufficient amounts.
What is SPO2
The pulse oximeter makes use of two frequencies of light (red and infrared) in order to gauge the percentage (%) of hemoglobin present in the blood that is dense with oxygen. The percentage calculated is called Blood Oxygen Saturation or SPO2. Hemoglobin molecules with attached oxygen molecules (Hbo2) absorb a different level of red and infrared light in comparison to hemoglobin molecules, which don’t have any oxygen molecule, attached (Hg). The difference range between absorption using an infrared light and a red light is used to gauge the SpO2 percentage. Each hemoglobin molecule can carry a load of four oxygen atoms and SPO2 is the sum percentage of hemoglobin molecules, which are oxygen-rich. Pulse oximeters also measure and display the pulse rate while measuring the SPO2 levels.
SpO2 readings are recorded in percentages. Normal levels of SpO2 rest between range of 95-100%.
Blood Oxygen Saturation levels can be read as follows:
- 90% or less: This is the red zone; you need to consider consulting your doctor.
- 91 to 94%: This percentage is lower than average for the population. It requires you to monitor your situation closely.
- 95 to 100%: This is the average for the majority of the population, the SPO2 normal values. This level indicates that your red blood cells are dense with oxygen, meaning they are transporting oxygen around the body sufficiently and efficiently.
Blood oxygen saturation levels that fall outside the range of 95 to 100% can cause a number of symptoms. Some of them are as follows:
- Trouble breathing
- Shortness of breath
- Increased heart rate
- A headache
- Chest pain
Acute and persistently lowSpO2 levels leads to a condition called Hypoxemia. Hypoxemia can pave way for various health issues including organ failure. Low oxygen levels can also cause serious problems such as lung disease and sleep apnea. These conditions may require additional oxygen to maintain the healthy functioning of cells and prevent long-term damage to them. Hypoxia can also be caused by asthma, emphysema, pneumonia, heart problems, and anemia.
During exercise, SpO2 levels gauge the amount of oxygen that is reaching the muscles during a regular workout. This is why it is extremely important to know SpO2 levels just after any sort of activity. High blood oxygen levels indicate that the body will transport oxygen throughout the body at a faster rate, which will, in turn, make workouts efficient and intense. Lowblood oxygen level mean that the body will transport oxygen to the muscles at a slower pace, which will cause fatigue and make the workout less effective. Essentially, blood oxygen saturation gauges the quality of heart and lung health. Lower readings indicate that the tester is unfit or suffers from an ailment or illness.
In addition, one of the biggest negative influences of lung health is smoking. Smokers tend to experience drastic improvements in both their mental and physical health if they can gain control of their habit or completely curb it. Changes include better mood regulation, increased lung capacity, and improved fitness levels, and an overall increase in energy levels.
Moreover, there are a variety of ways you can work to improve your blood oxygen level.
- Exercise: During workouts, the body has to work hard to keep SpO2 levels up. This can over time permanently increase SpO2 levels even when you are not exercising. An hour of aerobic exercise, for example, brisk walking, jogging, swimming, or dancing at least three times a week can make a marked improvement in your SpO2 levels.
- Fresh air: Sounds funny, but you can also increase oxygen levels by simply increasing the amount of oxygen you breath. Working out outside often can do this, opening windows in your house or offices, and increasing the number of live plants in your surroundings. These small changes will increase your fresh oxygen intake.
- Diet: Consuming foods such as raw fruits, green vegetables, seeds, and nuts will draw more oxygen into the blood and markedly improve SpO2 levels over time as they are rich in chlorophyll.
- Deep breathing: Oxygen deficiency can be dealt with by practicing deep breathing for a few minutes each day. Deep breathing entails filling the lungs to full capacity by expanding the chest and abdomen.
Understanding blood oxygen levels is important for everyone. However, it is particularly useful for those who exercise and is essential for people who suffer from low blood oxygen levels, such as those diagnosed with sleep apnea. However, while SPO2 provides an insight into your blood oxygen level, it is not a complete and comprehensive measurement of a person’s health. SPO2 measurements with an SPO2 sensor or an SPO2 monitor simply merely indicate that a diagnostic testing is needed, or other treatments should be taken into consideration.-->
Microsoft 365 licensing guidance for security & compliance.
Enable sensitivity labels for Office files in SharePoint and OneDrive so that users can apply your sensitivity labels in Office for the web. When this feature is enabled, users will see the Sensitivity button on the ribbon so they can apply labels, and see any applied label name on the status bar.
Enabling this feature also results in SharePoint and OneDrive being able to process the contents of files that have been encrypted by using a sensitivity label. The label can be applied in Office for the web, or in Office desktop apps and uploaded or saved in SharePoint and OneDrive. Until you enable this feature, these services can't process encrypted files, which means that coauthoring, eDiscovery, Data Loss Prevention, search, and other collaborative features won't work for these files.
After you enable sensitivity labels for Office files in SharePoint and OneDrive, for new and changed files that have a sensitivity label that applies encryption with a cloud-based key (and doesn't use Double Key Encryption):
For Word, Excel, and PowerPoint files, SharePoint and OneDrive recognize the label and can now process the contents of the encrypted file.
When users download or access these files from SharePoint or OneDrive, the sensitivity label and any encryption settings from the label are enforced and remain with the file, wherever it is stored. Ensure you provide user guidance to use only labels to protect documents. For more information, see Information Rights Management (IRM) options and sensitivity labels.
When users upload labeled and encrypted files to SharePoint or OneDrive, they must have at least view rights to those files. For example, they can open the files outside SharePoint. If they don't have this minimum usage right, the upload is successful but the service doesn't recognize the label and can't process the file contents.
Use Office for the web (Word, Excel, PowerPoint) to open and edit Office files that have sensitivity labels that apply encryption. The permissions that were assigned with the encryption are enforced. You can also use auto-labeling for these documents.
External users can access documents that are labeled with encryption by using guest accounts. For more information, see Support for external users and labeled content.
Office 365 eDiscovery supports full-text search for these files and Data Loss Prevention (DLP) policies support content in these files.
If encryption has been applied with an on-premises key (a key management topology often referred to as 'hold your own key' or HYOK), or by using Double Key Encryption, the service behavior for processing the file contents doesn't change. So for these files, coauthoring, eDiscovery, Data Loss Prevention, search, and other collaborative features won't work.
The SharePoint and OneDrive behavior also doesn't change for existing files in these locations that are labeled with encryption using a single Azure-based key. For these files to benefit from the new capabilities after you enable sensitivity labels for Office files in SharePoint and OneDrive, the files must be either downloaded and uploaded again, or edited.
After you enable sensitivity labels for Office files in SharePoint and OneDrive, three new audit events are available for monitoring sensitivity labels that are applied to documents in SharePoint and OneDrive:
- Applied sensitivity label to file
- Changed sensitivity label applied to file
- Removed sensitivity label from file
Watch the following video (no audio) to see the new capabilities in action:
You always have the choice to disable sensitivity labels for Office files in SharePoint and OneDrive (opt-out) at any time.
If you are currently protecting documents in SharePoint by using SharePoint Information Rights Management (IRM), be sure to check the SharePoint Information Rights Management (IRM) and sensitivity labels section on this page.
These new capabilities work with sensitivity labels only. If you currently have Azure Information Protection labels, first migrate them to sensitivity labels so that you can enable these features for new files that you upload. For instructions, see How to migrate Azure Information Protection labels to unified sensitivity labels.
Use the OneDrive sync app version 19.002.0121.0008 or later on Windows, and version 19.002.0107.0008 or later on Mac. Both these versions were released January 28, 2019, and are currently released to all rings. For more information, see the OneDrive release notes. After you enable sensitivity labels for Office files in SharePoint and OneDrive, users who run an older version of the sync app are prompted to update it.
There is a current problem with Power Query and custom add-ins with Excel on the web: Do not encrypt these files by using sensitivity labels because data can be lost when the file is saved. Instead, apply a label without encryption.
SharePoint and OneDrive don't automatically apply sensitivity labels to existing files that you've already encrypted using Azure Information Protection labels. Instead, for the features to work after you enable sensitivity labels for Office files in SharePoint and OneDrive, complete these tasks:
Make sure you have migrated the Azure Information Protection labels to sensitivity labels and published them from the Microsoft 365 compliance center, or equivalent labeling admin center.
Download the files and then upload them to SharePoint.
SharePoint and OneDrive can't process encrypted files when the label that applied the encryption has any of the following configurations for encryption:
- Let users assign permissions when they apply the label and the checkbox In Word, PowerPoint, and Excel, prompt users to specify permissions is selected. This setting is sometimes referred to as 'user-defined permissions'.
- User access to content expires is set to a value other than Never.
- Double Key Encryption is selected.
For labels with any of these encryption configurations, the labels aren't displayed to users in Office for the web. Additionally, the new capabilities can't be used with labeled documents that already have these encryption settings. For example, these documents won't be returned in search results, even if they are updated.
Users might experience delays in being able to open encrypted documents in the following Save As scenario: Using a desktop version of Office, a user chooses Save As for a document that has a sensitivity label that applies encryption. The user selects SharePoint or OneDrive for the location, and then immediately tries to open that document in Office for the web. If the service is still processing the encryption, the user sees a message that the document must be opened in their desktop app. If they try again in a couple of minutes, the document successfully opens in Office for the web.
For encrypted documents, printing is not supported.
For an encrypted document that grants edit permissions to a user, copying can't be blocked in the web versions of the Office apps.
By default, Office desktop apps and mobile apps don't support co-authoring for files that are labeled with encryption. These apps continue to open labeled and encrypted files in exclusive editing mode.
Co-authoring is now supported in preview. For more information, see Enable co-authoring for files encrypted with sensitivity labels.
If an admin changes settings for a published label that's already applied to files downloaded to users' sync client, users might be unable to save changes they make to the file in their OneDrive Sync folder. This scenario applies to files that are labeled with encryption, and also when the label change is from a label that didn't apply encryption to a label that does apply encryption. Users see a red circle with a white cross icon error, and they are asked to save new changes as a separate copy. Instead, they can close and reopen the file, or use Office for the web.
If a labeled document is uploaded to SharePoint or OneDrive and the label applied encryption by using an account from a service principal name, the document can't be opened in Office for the web. Example scenarios include Microsoft Cloud App Security and a file sent to Teams by email.
Users can experience save problems after going offline or into a sleep mode when instead of using Office for the web, they use the desktop and mobile apps for Word, Excel, or PowerPoint. For these users, when they resume their Office app session and try to save changes, they see an upload failure message with an option to save a copy instead of saving the original file.
Documents that have been encrypted in the following ways can't be opened in Office for the web:
- Encryption that uses an on-premises key ('hold your own key' or HYOK)
- Encryption that was applied by using Double Key Encryption
- Encryption that was applied independently from a label, for example, by directly applying a Rights Management protection template.
Labels configured for other languages are not supported and display the original language only.
Screen captures can't be prevented for encrypted documents. For more information, see Can Rights Management prevent screen captures?
If you delete a label that's been applied to a document in SharePoint or OneDrive, rather than remove the label from the applicable label policy, the document when downloaded won't be labeled or encrypted. In comparison, if the labeled document is stored outside SharePoint or OneDrive, the document remains encrypted if the label is deleted. Note that although you might delete labels during a testing phase, it's very rare to delete a label in a production environment.
How to enable sensitivity labels for SharePoint and OneDrive (opt-in)
You can enable the new capabilities by using the Microsoft 365 compliance center, or by using PowerShell. As with all tenant-level configuration changes for SharePoint and OneDrive, it takes about 15 minutes for the change to take effect.
Use the compliance center to enable support for sensitivity labels
Spo2 Levels Chart
This option is the easiest way to enable sensitivity labels for SharePoint and OneDrive, but you must sign in as a global administrator for your tenant.
Sign in to the Microsoft 365 compliance center as a global administrator, and navigate to Solutions > Information protection
If you don't immediately see this option, first select Show all.
If you see a message to turn on the ability to process content in Office online files, select Turn on now:
The command runs immediately and when the page is next refreshed, you no longer see the message or button.
If you have Microsoft 365 Multi-Geo, you must use PowerShell to enable these capabilities for all your geo-locations. See the next section for details.
Use PowerShell to enable support for sensitivity labels
As an alternative to using the compliance center, you can enable support for sensitivity labels by using the Set-SPOTenant cmdlet from SharePoint Online PowerShell.
If you have Microsoft 365 Multi-Geo, you must use PowerShell to enable this support for all your geo-locations.
Prepare the SharePoint Online Management Shell
Before you run the PowerShell command to enable sensitivity labels for Office files in SharePoint and OneDrive, ensure that you're running SharePoint Online Management Shell version 16.0.19418.12000 or later. If you already have the latest version, you can skip to next procedure to run the PowerShell command.
If you have installed a previous version of the SharePoint Online Management Shell from PowerShell gallery, you can update the module by running the following cmdlet.
Alternatively, if you have installed a previous version of the SharePoint Online Management Shell from the Microsoft Download Center, you can also go to Add or remove programs and uninstall the SharePoint Online Management Shell.
In a web browser, go to the Download Center page and Download the latest SharePoint Online Management Shell.
Select your language and then click Download.
Choose between the x64 and x86 .msi file. Download the x64 file if you run the 64-bit version of Windows or the x86 file if you run the 32-bit version. If you don’t know, see Which version of Windows operating system am I running?
After you have downloaded the file, run the file and follow the steps in the Setup Wizard.
Run the PowerShell command to enable support for sensitivity labels
To enable the new capabilities, use the Set-SPOTenant cmdlet with the EnableAIPIntegration parameter:
Using a work or school account that has global administrator or SharePoint admin privileges in Microsoft 365, connect to SharePoint. To learn how, see Getting started with SharePoint Online Management Shell.
Note: If you have Microsoft 365 Multi-Geo, use the -Url parameter with Connect-SPOService, and specify the SharePoint Online Administration Center site URL for one of your geo-locations.
Run the following command and press Y to confirm:
For Microsoft 365 Multi-Geo: Repeat steps 1 and 2 for each of your remaining geo-locations.
Publishing and changing sensitivity labels
When you use sensitivity labels with SharePoint and OneDrive, keep in mind that you need to allow for replication time when you publish new sensitivity labels or update existing sensitivity labels. This is especially important for new labels that apply encryption.
For example: You create and publish a new sensitivity label that applies encryption and it very quickly appears in a user's desktop app. The user applies this label to a document and then uploads it to SharePoint or OneDrive. If the label replication hasn't completed for the service, the new capabilities won't be applied to that document on upload. As a result, the document won't be returned in search or for eDiscovery and the document can't be opened in Office for the web.
The following changes replicate within one hour: New and deleted sensitivity labels, and sensitivity label policy settings that include which labels are in the policy.
The following changes replicate within 24 hours: Changes to sensitivity label settings for existing labels.
Because the replication delay is only one hour for new sensitivity labels, you are unlikely to run into the scenario in the example. But as a safeguard, we recommend publishing new labels to just a few test users first, wait for an hour, and then verify the label behavior on SharePoint and OneDrive. As the final step, make the label available to more users by either adding more users to the existing label policy, or add the label to an existing label policy for your standard users. At the time your standard users see the label, it has already synchronized to SharePoint and OneDrive.
SharePoint Information Rights Management (IRM) and sensitivity labels
SharePoint Information Rights Management (IRM) is an older technology to protect files at the list and library level by applying encryption and restrictions when files are downloaded. This older protection technology is designed to prevent unauthorized users from opening the file while it's outside SharePoint.
In comparison, sensitivity labels provide the protection settings of visual markings (headers, footers, watermarks) in addition to encryption. The encryption settings support the full range of usage rights to restrict what users can do with the content, and the same sensitivity labels are supported for many scenarios. Using the same protection method with consistent settings across workloads and apps results in a consistent protection strategy.
However, you can use both protection solutions together and the behavior is as follows:
If you upload a file with a sensitivity label that applies encryption, SharePoint can't process the content of these files so coauthoring, eDiscovery, DLP, and search are not supported for these files.
If you label a file using Office for the web, any encryption settings from the label are enforced. For these files, coauthoring, eDiscovery, DLP, and search are supported.
If you download a file that's labeled by using Office for the web, the label is retained and any encryption settings from the label are enforced rather than the IRM restriction settings.
If you download an Office or PDF file that isn't encrypted with a sensitivity label, IRM settings are applied.
If you have enabled any of the additional IRM library settings, which include preventing users from uploading documents that don't support IRM, these settings are enforced.
Spo Level 1 Course
With this behavior, you can be assured that all Office and PDF files are protected from unauthorized access if they are downloaded, even if they aren't labeled. However, labeled files that are uploaded won't benefit from the new capabilities.
Search for documents by sensitivity label
Use the managed property InformationProtectionLabelId to find all documents in SharePoint or OneDrive that have a specific sensitivity label. Use the following syntax:
For example, to search for all documents that have been labeled as 'Confidential', and that label has a GUID of '8faca7b8-8d20-48a3-8ea2-0f96310a848e', in the search box, type:
To get the GUIDs for your sensitivity labels, use the Get-Label cmdlet:
First, connect to Office 365 Security & Compliance Center PowerShell.
For example, in a PowerShell session that you run as administrator, sign in with a global administrator account.
Then run the following command:
For more information about using managed properties, see Manage the search schema in SharePoint.
Remove encryption for a labeled document
There might be rare occasions when a SharePoint administrator needs to remove encryption from a document stored in SharePoint. Any user who has the Rights Management usage right of Export or Full Control assigned to them for that document can remove encryption that was applied by the Azure Rights Management service from Azure Information Protection. For example, users with either of these usage rights can replace a label that applies encryption with a label without encryption. Alternatively, a super user could download the file and save a local copy without the encryption.
As an alternative, a global admin or SharePoint admin can run the Unlock-SPOSensitivityLabelEncryptedFile cmdlet, which removes both the sensitivity label and the encryption. This cmdlet runs even if the admin doesn't have access permissions to the site or file, or if the Azure Rights Management service is unavailable.
SharePoint Online Management Shell version 16.0.20616.12000 or later.
The encryption has been applied by a sensitivity label with admin-defined encryption settings (the Assign permissions now label settings). Double Key Encryption is not supported for this cmdlet.
The justification text is added to the audit event of Removed sensitivity label from file, and the decryption action is also recorded in the protection usage logging for Azure Information Protection.
How to disable sensitivity labels for SharePoint and OneDrive (opt-out)
If you disable these new capabilities, files that you uploaded after you enabled sensitivity labels for SharePoint and OneDrive continue to be protected by the label because the label settings continue to be enforced. When you apply sensitivity labels to new files after you disable these new capabilities, full-text search, eDiscovery, and coauthoring will no longer work.
To disable these new capabilities, you must use PowerShell. Using the SharePoint Online Management Shell and the Set-SPOTenant cmdlet, specify the same EnableAIPIntegration parameter as described in the Use PowerShell to enable support for sensitivity labels section. But this time, set the parameter value to false and press Y to confirm:
If you have Microsoft 365 Multi-Geo, you must run this command for each of your geo-locations.
After you've enabled sensitivity labels for Office files in SharePoint and OneDrive, consider automatically labeling these files by using auto-labeling policies. For more information, see Apply a sensitivity label to content automatically.
