The gradient between the partial pressure of oxygen in the alveolar spaces and the arterial blood: P(A-a)02. Normally, in young adults this value is less than 20 mmHg. Medical Dictionary for the Health Professions and Nursing © Farlex 2012 ...
The cerebral arterial oxygen saturation, ScaO2 was estimated using an empirically derived formula for estimating oxygen saturation in pulse oximetry from the 'ratio-of-ratios' (enclosed within the parentheses in the equation) [19]: ScaO2 = 110 ! " 25$ # Acard ,R Acard ,IR ADC ,R AD...
Expected values for each parameter were referenced from the Wasserman formula. Recorded CPET parameters included peak oxygen uptake (peakVO2), carbon dioxide output (VCO2), minute ventilation (VE), and VE/VCO2 slope. The anaerobic threshold was determined using the V-slope method. Six-minute ...

At high altitude with hypoxia, ventilation is improved to maintain the oxygen content in the blood as a form of body regularization, which consequently leads to a decreased level of CO2 in the blood27. However, the low oxygen level as a result of hypoxia and decreased CO2 (known as hypocapn...

Given the high dose of melatonin, a prolonged-released formula would have increased the risk over hang over effect, which was not considered beneficial for the participants. Previous studies report a significant effect of melatonin on blood pressure10. However, the results may be debatable as the...

In ABG analysis, oxygen saturation is a calculated value derived by extrapolating from the PO2, which is the amount of dissolved oxygen in blood (only about 1.5% of blood total oxygen content) rather than by directly measuring the oxygen saturation of hemoglobin. It is usually very accurate...
