The body maintains a stable level of oxygen saturation for the most part by chemical processes of aerobic metabolism associated with breathing.Using the respiratory system, red blood cells, specifically the hemoglobin, gather oxygen in the lungs and distribute it to the rest of the body.
An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide.An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle, [1] but sometimes the femoral artery in the groin or another site is used.
Pulse Oximetry: measures the fraction of hemoglobin saturated with oxygen (SpO2). [1] Imaging (eg. ultrasonography, radiography) may be used to assist in the diagnostic workup. For example, it may be utilized to determine the etiology of a person's respiratory failure. Arterial blood gas analyzer
A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements.

Blood gas tension refers to the partial pressure of gases in blood. [1] There are several significant purposes for measuring gas tension. [2] The most common gas tensions measured are oxygen tension (P x O 2), carbon dioxide tension (P x CO 2) and carbon monoxide tension (P x CO). [3]
The BRAT diet (bananas, rice, applesauce and toast) can work well.Try a little food and see how you feel, then eat a little more as you can tolerate it. “Avoid aggravating GI symptoms by not ...
The Weeknd’s “Hurry Up Tomorrow” is the No. 1 album on the Billboard 200 with a staggering 490,500 equivalent album units, making it the biggest debut of 2025.
Negative pressure pulmonary edema [27] is when inspiration is attempted against some sort of obstruction in the upper airway, most commonly happens as a result of laryngospasm in adults. This negative pressure in the chest ruptures capillaries and floods the alveoli with blood [28] Pulmonary embolism [29]
