WebbAs an interesting side note, this oxygen hemoglobin association curve illustrates why climbers who climb higher than 15,000 feet have oxygen saturation that drops below 90% and begin to experience acute altitude sickness. At 30,000 feet, the height of Mt. Everest, the pO2 mmHg drops to 31, which is only 60% O2 saturation on the curve.

WebbIn zone 2, ventilation is equal to perfusion; generating a V/Q ratio of about 1. In zone 3, the flow of air and blood is the highest with ventilation of around 0.8 L/min, and perfusion of around 1.3 L/min; generating a V/Q ratio of 0.6. So the V/Q ratio varies depending on which part of the lung is involved, but the overall ratio is an average ... WebbArterial blood for blood-gas analysis is usually drawn by a respiratory therapist and sometimes a phlebotomist, a nurse, a paramedic or a doctor.

Webb10 juni 2024 · The reason that the total pressure decreases is that pressure is essentially a measure of the weight of 'stuff' above you; in this case atmospheric gas. As you go higher up, you are putting more of the atmosphere below you, leaving less of it above you. Therefore the weight of gas pressing down on you decreases because there is less gas. … Webb28 feb. 2024 · The oxygen-poor air at high elevations force your lungs to work much harder to get enough oxygen than they would have to at sea level.
