Webb16 aug. 2016 · P O₂ in the body cells is less than 40 mmHg. Because P O₂ in the systemic capillaries is greater than the partial pressure in the body cells, oxygen diffuses from the blood and into the cells. Leaving the systemic capillaries, P O₂ = 40 - 50 mmHg. Entering the alveolar capillaries WebbQuestion: Which of the following would decrease the partial pressure of oxygen (PO2) in arterial blood?

WebbAlveolar Gas Equation. The alveolar gas equation is a formula used to approximate the partial pressure of oxygen in the alveolus (PAO2):PAO2= (PB−PH2O)FiO2− (PaCO2÷R)where PB is the barometric pressure, PH2O is the water vapor pressure (usually 47mmHg), FiO2 is the fractional concentration of inspired oxygen, and R is the gas …

Llamas are native to the Andes Mountains in South America. The partial pressure of O2 (abbreviated PO2) in the atmosphere where llamas live is about half of the PO2 at sea level. As a result, the PO2 in the lungs of llamas is about …
