Web9 jan. 2016 · PAO2 = .21 (760 – 47) – 80/0.8 = 49 mmHg. Normal PAO2 is about 100 mmHg, so this is quite hypoxic, especially since the alveolar PAO2 is always a little higher than the arterial PaO2. If it weren’t, oxygen would not flow out of the alveoli into the blood — it would stay in the alveoli. Web8 feb. 2024 · Maintaining the pH of blood is essential for normal bodily function; however, several clinical scenarios can result in disruption of the body’s acid-base balance. Monitoring of acid-base balance is done by testing patients’ arterial blood gases (ABGs). The results of ABG testing will often influence the treatment that patients receive. …

WebThis is what makes you feel shortness of breath ( dyspnea ). 1. Still, because air can get in, oxygen can get in. Since oxygen can get past obstructed airways, it travels to alveoli. From there, it crosses over to your blood system. And in this way, your oxygen levels stay in the normal range even during most asthma attacks.

When the body is functioning normally, PaO2 is between 75 and 100 mmHg (at sea level). A result in this range means a sufficient amount of oxygen is flowing from the alveoli to the blood.
