A new sensor could soon allow hospital patients' blood oxygen levels to be checked via their breath. The technology is claimed to be more reliable and less painful than existing traditional methods.

When blood oxygen falls below 75 mmHg, the condition is generally termed as hypoxemia. If it further falls down to 60 mmHg, it may call for emergency support and a supplemental oxygen may be ...

Blood oxygen saturation is important to normal healthy functions in the, particularly for lung functions. Blood oxygen levels received renewed attention as an essential vital sign during the COVID-19 ...

Oxygen saturation measures the percentage of oxyhemoglobin (oxygen-bound hemoglobin) in the blood, and it is represented as arterial oxygen saturation (SaO 2) and venous oxygen saturation (SvO 2).

There has been a sudden interest about blood oxygen levels due to the COVID-19 pandemic. Find out the what, why and how of it right here. You might be hearing the term ‘blood oxygen levels’ everywhere ...

But blood oxygen, or SpO2, levels have been used long before COVID-19 as an important indicator for your heart, lung and overall health. Simply put, your blood oxygen level (or SpO2 level) is the ...

I’ve been testing the blood oxygen sensor on the Apple Watch Series 6 for the past few weeks under a range of conditions. I’ve been comparing my results against two consumer-grade fingertip sensors ...

By contrast, a healthy person should have blood oxygen levels of at least 95%, and typically require medical attention if those levels drop below 90%. In its current form, the app is able to ...
