Be aware that multiple factors can affect the accuracy of a pulse oximeter reading, such as poor circulation, skin pigmentation, skin thickness, skin temperature, current tobacco use, and use of fingernail polish.
What will be the oxygen level in Covid-19?
Some COVID-19 patients may show no symptoms at all. You should start oxygen therapy on any COVID-19 patient with an oxygen saturation below 90 percent, even if they show no physical signs of a low oxygen level. If the patient has any warning signs of low oxygen levels, start oxygen therapy immediately.

How to read pulse oximeter?
To get the best reading from a pulse oximeter: Follow the manufacturer’s instructions for use. When placing the oximeter on your finger, make sure your hand is warm, relaxed, and held below the level of the heart. Remove any fingernail polish on that finger.
How to interpret pulse oximeter reading?
How to interpret a reading: When taking pulse oximeter measurements, pay attention to whether the oxygen level is lower than earlier measurements, or is decreasing over time. Changes or trends in measurements may be more meaningful than one single measurement.

What is the purpose of a pulse oximeter?
A pulse oximeter is a device that is usually placed on a fingertip. It uses light beams to estimate the oxygen saturation of the blood and the pulse rate. Oxygen saturation gives information about the amount of oxygen carried in the blood.
What factors affect the accuracy of a pulse oximeter?
Be aware that multiple factors can affect the accuracy of a pulse oximeter reading, such as poor circulation, skin pigmentation, skin thickness, skin temperature, current tobacco use, and use of fingernail polish.
What is the most important number in oxygen saturation?
The most important number, oxygen saturation level, is usually abbreviated SpO 2, and is presented as a percentage. The pulse rate (similar to heart rate) is abbreviated PR, and sometimes there is a third number for strength of the signal.

OTC oximeters are not cleared by the FDA and should not be used for medical purposes. For more information on pulse oximeter regulation, see Pulse Oximeters - Premarket Notification Submissions [510 (k)s]: Guidance for Industry and Food and Drug Administration Staff.
How long to wait for oxygen saturation to stabilize?
Place the oximeter on the patient’s finger and wait until the oxygen saturation reading is stabilized for at least 1 min. If after a minute it continues to fluctuate, say for example between 93 and 96%, record the average value or the most persistent value as well as the range.
When a patient stops exercising, should you record?
When the patient stops exercising, you should record: the oximetry and puls e rate immediately following cessation of exercise, the time of exercise, the number of steps the patient took (so you’ll need to count the steps during the test), and record why the patient stopped.
Why don't you touch the finger on an oximeter?
Don’t touch the finger on which the oximeter is placed however because pressure or motion artifacts on the oximeter can lead to measurement error.
Why do you record exercise time with a stopwatch?
Record the patient’s exercise time with a stopwatch because it’s much more accurate than your wristwatch. The patient is asked to climb on and off the 18 cm step. Ask the patient to do this at a rate that’s comfortable for them and that they’ll be able to keep doing for 3 min.
Is exercise oximetry contraindicated for angina?
Exercise oximetry is contraindicated in patients with unstable ischemic heart disease. However, stable angina is not a contraindication to exercise oximetry. Patients who have severe arthritis or back pain or leg weakness and who are unable to walk won’t benefit from the test.
Is it normal for oxygen saturation to be 95%?
It is normal for the oxygen saturation to fall up to 3%. Thus, if the resting baseline oxygen saturation is 95%, a fall with exercise to a low of 92% would be normal.
Can nail polish interfere with oxygen saturation?
Don’t let the hand with the oximeter on it swing freely as that will cause a motion artifacts that can cause inaccuracy. Also nail polish can interfere with the oxygen saturation accuracy. So if the patient has nail polish on, remove it or place the oximetry sensor as high as possible on the little finger.
What is a field walking test?
Field walking tests may be performed to identify the patient’s exercise capacity (peak exercise capacity, functional exercise capacity or endurance), factors limiting exercise performance (dyspnoea, subjective fatigue, musculoskeletal limitations) and often their response to an intervention. The field tests can also be used to identify a threshold to predict survival and the likelihood of a hospital readmission, with a more extensive body of evidence reporting use of 6MWD rather than ISWT or ESWT for this purpose [2]. Prescription of exercise intensity for pulmonary rehabilitation may also be a consideration. The 6MWT and the ISWT/ESWT have been reported in all of these circumstances [2]
What is the acronym for the 6-min walk test?
The European Respiratory Society (ERS) and American Thoracic Society (ATS) have recently published a Technical Standard which documents the standard operating procedures for the 6-min walk test (6MWT), incremental shuttle walk test (ISWT) and endurance shuttle walk test ( ESWT). The Technical Standard shows that all three tests are valid and reliable measures of functional exercise capacity in people with chronic respiratory disease and makes recommendations for standardising their performance. Key findings and recommendations of the Technical Standard include:
