In a proof-of-principle study, University of Washington and University of California San Diego researchers have shown that smartphones are capable of detecting blood oxygen saturation levels down to 70%.
On your iPhone, open the Health app. Follow the onscreen steps. If you don't see a prompt to set up, tap the Browse tab, then tap Respiratory > Blood Oxygen > Enable. After you complete setup, open the Blood Oxygen app on your Apple Watch to measure your blood oxygen levels.
Both Samsung S9 and S10 contain the same integrated pulse oximeter, thus over 100 million smartphones in current global circulation could be used to obtain clinically accurate spot SpO2 measurements to support at home assessment of COVID-19 patients.
To do this, place your hand on your chest and count the number of times you breathe. If your respiratory rate is more than 30, you might have a low oxygen level.
Symptoms of low blood oxygen levels
Low blood oxygen levels can result in abnormal circulation and cause the following symptoms: shortness of breath. headaches. restlessness.
Can I check my blood oxygen (SP02) levels at home? Yes! Using a Finger Pulse Oximeter, which is a small device that is attached to your finger to measure the amount of oxygen in the blood travelling round your body. The Oximeter takes an SpO2 reading – an estimation of the amount of oxygen in your blood.
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.
While many of the available heart rate apps, watches, and fitness trackers seem to be reasonably accurate, they don't take the place of visiting a doctor. If you have symptoms or concerns, regardless of what your device says, you should see a doctor.

The Apple Watch is very close to achieving accuracy levels of a pulse oximeter. The blood oxygen level (which is called SpO2 in the study) bias across all data points was 0 percent. Here's the rest: “The bias for SpO2 less than 90% was 1.2%.
Apple Watch — Series 6 or later, excluding Apple Watch SE1 — is capable of measuring oxygen saturation of arterial hemoglobin (SpO2) for fitness and wellness applications. The Apple Watch optical system uses a combination of light emitters and light sensors to take the blood oxygen measurement.
People with Long COVID can have a wide range of symptoms that can last weeks, months, or even years after infection. Sometimes the symptoms can even go away and come back again.
But some people may be infectious for up to 10 days. Symptoms in children and babies are milder than those in adults, and some infected kids may not show any signs of being unwell. People who experience more serious illness may take weeks to recover. Symptoms may continue for several weeks after infection.
Normal oxygen saturation is 96-100% and it should not go below 88% during exercise. Stop exercising and rest if you see a drop in your oxygen saturation below 88%. BEGIN this exercise program after discharge from the hospital and have no fever.
Pulse oximeters are most accurate when blood oxygen saturation is between 90% and 100%. Accuracy decreases when blood oxygen saturation is between 80% and 90%, and the devices are least accurate when saturation is below 80%. Keep in mind that readings may be off by a few percentage points.
Three studies in type 1 diabetes have demonstrated an ~0.5% lower blood oxygen saturation compared with non-diabetic controls (2, 3, 22).
The iSpO2® pulse oximeter comes in four versions – small and large options for the lightning connectors (iOS devices) and micro USB (Android devices)
Shortness of breath does not equal saturation (SaO2%)
In other words, your level of dyspnea, or air hunger, does not always correlate with your oxygen saturation. This means that you can be short of breath, even extremely short of breath, even in the presence of normal oxygen saturation.
A person may have dyspnea even though the actual levels of oxygen are within a normal range. It is important to understand that people do not suffocate or die from dyspnea. But tell your health care team right away if you have any of these symptoms or if they get worse.
Stress can affect all systems of the body — even leading to lower oxygen levels in the blood and body. If you sometimes feel short of breath when you're stressed or anxious, you are not alone. This is a common symptom of anxiety.
