Hypoxemia (or Hypoxaemia) is generally defined as decreased partial pressure of oxygen in blood, sometimes specifically as less than which, without further specification, would include both concentration of dissolved oxygen and oxygen bound to hemoglobin.

Does high-dose inhaled nitric oxide improve respiratory function and outcomes among pregnant patients hospitalized with severe COVID-19 pneumonia?

Pulse oximeter inaccuracies may be associated with racial disparities in care

For most patients, a pulse oximeter is a familiar device from visits to the doctor's office. Placed on a finger or a patient's ear lobe, pulse oximeters are an easy way to quickly get a measure of someone's oxygen saturation (SpO2), which should generally be above 90 percent.

Overt and occult hypoxemia in patients hospitalized with COVID-19

In a recent study posted to the medRxiv* preprint server, researchers assessed whether non-invasive estimation of the ratio of arterial oxygen partial pressure (PaO2) to the fractional inspired oxygen (Fi O2), i.e., the P/F ratio could measure overt and occult hypoxemia in coronavirus disease 2019 (COVID-19) patients.
