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 fin

The ventilatory response to hypoxia (PAO2 55 and 45 Torr) at each of four levels of PACO2 was studied in five healthy subjects before and after a rise in rectal temperature of 1.4 degrees C had been induced by means of a heated flying su... ES Petersen,H Vejby-Christensen - 《J Appl...
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 ...
were obviously lower than those in control group. The levels of PaO2at OLV 15,30min in two group were both lower than those at TLV, and increased at TLV recovery. The levels of PaCO2at OLV15,30min in observe group were higher than those at TLV, and increased at TLV ...
(PaO2)、血氧饱和度(SpO2)、氧合指标(PaO2/FiO2)显著升高,二氧化碳分压(PaCO2)水平显著降低,而CD8+水平变化不明显;治疗后观察组老年患者免疫细胞(CD3+、CD4+和CD4+/CD8+)、肺功能指标(FVC、PEF、FEV1及MMEF)和血气指标(PaO2、SpO2、PaO2/FiO2)显著高于治疗后对照组,PaCO2水平显著低于治疗后对...
