Above 120 mmHg: Hyperoxemia is defined as blood oxygen levels above 120 mmHg. Hyperoxemia is mostly seen in hospitals when patients are exposed to high pressures of supplemental oxygen for prolonged periods (3 to more than 10 hours). 75-100 mmHg: Normal arterial oxygen pressure (PaO2) is ...
Despite comparable usual physical activity levels and comparable heart rates at exhaustion, the type 2 diabetes group had a lower peak oxygen consumption than controls. No significant differences were found in arterial blood gas analyses (PaO2" role="presentation" style="position: relative;">PaO2PaO2...
In addition, oxygen saturation may also be elevated during oxygen therapy. However, if there is already an adequate supply of oxygen in the blood, the additional addition of O2 can increase the risk of lung failure, heart attacks, cardiac arrhythmias and organ failure. Too much oxygen is toxic...

A 36-year-old woman is found comatose at her home and is life-flighted to the nearest regional medical center.Blood gases reveal a normal PaO2 but a lower-thannormal arterial O2 saturation.Which of the following conditions is most consistent with the find答案...
PaO2 less than 50 mm Hg or PaCO2 greater than 50 mm Hg A person with normal lungs at sea level (760 mmHg) is breathing 50% oxygen. What is the approximate alveolar PO2? When the lungs are compressed or deflated, a/an ___ rate o...
Simulated exercise was done while the subjects took a rest by regulating arterial blood gases at exercise levels in patients and at PaO2 = 65 mm Hg and PaCO2 = 48 mm Hg in normal subjects. In normal subjects, the role of arterial blood gases in determining exercise ventilation, cardiac ...
