Throughout the period the lambs' mean PaCO2 (33.1 mm Hg) and pH (7.46) values were similar to those determined in the adult sheep (PaCO232.1 mm Hg; pH 7.48). The lamb's mean PaO2 increased from 63.3 mm Hg at two weeks of age to about 80 mm Hg at eight weeks and by 20 weeks ...
无支气管肺部感染病史,吸入空气下动脉血气值为PaO2 83 mmHg,PaCO2 38 mmHg,pH 7.40,HCO3- 25 mM。心电图显示窦性心律,术前血压128/65 mmHg。病人不接受术后硬膜外镇痛。麻醉采用39F左侧双腔管支气管插管,纤维支气管镜确认导管位置正确后,将病人置于侧卧位。采用容量控制通气,FiO2 100% 情况下设置潮气量(VT)...
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 ...
Normal PaCO2 range 35-45 mmHg Normal HCO3 range 22-26 mEq/L An acute respiratory acidosis is also called ___ Acute ventilatory failure, hypercapnia, hypoventilation A PaO2 between 40-59 mmHg indicates what level of hypoxemia? moderate hypoxemia A...
An increasingly negative mean chamber pressure was associated with a significant increase in PaO2 (p less than 0.05) and VL(p less than 0.005) and a significant decrease in PaCO2 (p less than 0.025).(ABSTRACT TRUNCATED AT 250 WORDS) 展开 ...

To assess the temporal relationship between fluid balance and cardiopulmonary function in hyaline disease (HMD), serial measurements were made of pulmonary gas exchange (Pa/A O2, PaO2, PaCO2), ventilation indices (FIO2, Ppeak, Pmin, freq... J Delemos,G Dryer,D Gerstmann,... - 《Journal of...
An ordinary way of doing business without meditation and fasting.
Before and after treatment, arterial blood gas index, duration of ventilation, hospitali-zation time, pulmonary infection and the injury of nasal mucosa of three groups were compared. Results On the view of arterial blood gas index, the PaCO2were lower, PaO2was higherof the n...
Objective To evaluate the effect of non-invasive positive pressure ventilation in the treatment of COPD patients with Ⅱ respiratory failure by monitoring the arterial blood gas indicators (pH, PaO2, PaCO2)changes. 结论无创性正压通气治疗COPDⅡ型呼吸衰竭患者疗效显著。5...
