You wrote in the manuscript: The PaO2 values obtained from the ABG samples will be compared to the peripheral oxygen saturation (SpO2), which will be used as a continuous guide. Comment: the SpO2 is a very poor guide for PaO2 above 10-15kPa. Even with a PaO2 of 10kPa th...
It has, however, become common practice to use arterial instead of alveolar CO2 tension for computing alveolar oxygen tension (PAO2) and physiological dead space, not only in normal subjects but also in patients. The purpose of this study was to estimate alveolar CO2 tension during spontaneous ...
Methods Ten normal volunteers were recruited from the research staff of King's College Hospital. Six patients with COPD and hypoxia (arterial oxygen tension (Pao2) <8 5 kPa) were recruited from the thoracic medicine outpatient clinic at King's College Hospital and five age and sex matched ...
How does a decrease in the partial pressure of CO_2 in the lungs from 6 kPa (holding one's breath) to 2 kPa (normal) effect the following changes on the O_2 affinity of hemoglobin? What is the normal range of breaths per minute f...
