Normal Value pH 7.30 7.35-7.45 PaO2 50 90-100 PaCo2 65 40 HCO3 20 24 1. Interpreting common lab values But the peripheral chemoreceptors respond more rapidly to decreased or increased arterial oxygen partial pressure (PaO2), decreased or increased PaCO2, and increased or decreased arterial pH ...
Other parameters, such as PaCO2 (partial pressure of carbon dioxide) and pH levels, are also considered to obtain a comprehensive picture of respiratory status. 中文回答: PaO2,即动脉血氧分压,正常范围通常在75到100 mmHg之间。这个测量值在评估个体的氧合状态中非常重要,经常用于监测呼吸功能。 PaO2水平...
目的研究与ARDS密切相关的几个生理指标.方法 KM小鼠动物血pH,PaO2,PaCO2由美国NOVA血气分析直接测定,PQ中毒LD50以寇氏法计算.肺系数由湿重除以体重乘100%得出数值.结果 KM小鼠正常动脉血pH值为7.3605±0.067,PaO2(kPa)为12.47±1.3413,PaCO2(kPa)5.26±0.4949;肺系数(%)为0.6662±0.082;百草枯(paraquat,PQ)中毒LD50为...
Relaxed chickens, artificially ventilated at different 'values of f resp and V t, were also exposed to hypercapnic hypoxia. When f resp and V t were at those values previously recorded in normal control animals, hypercapnic hypoxia caused f card a to fall to 81% of control. This bradycardia...
A Control Ventilation mode throughout the whole experiment with FiO2:0,4 was adequate in order to keep PaO2> 100mmHg, while others ventilator parameters were set in values to achieve PaCO2 30-50mmHg and pH 7,2 – 7,6. In the study group sepsis was provoked with intravenously infused ...
Blood electrolytes, hemoglobin concentration, and renal function were normal. There was no history of bronchopulmonary infection, and arterial blood gas values in room air were PaO2 83 mmHg, PaCO2 38 mmHg, pH 7.40, and HCO3 25 mM. Electrocardiogram showed regular sinus rhythm, and blood pressure...
PaO2is the most important (but not the only) determinant of SaO2. Other determinants of SaO2for a given PaO2are conditions that shift the position of the oxygen dissociation curve left or right, such as temperature, pH, PaCO2and level of 2,3-DPG in the blood. Shifts of the O2-dissociatio...
With a high normal PaCO2 (greater than 6.0 kPa) and high PaO2 (greater than 30 kPa), HFV and PEEP (0.5 kPa) decreased PNA by a mean of only 30%. When PaO2 was decreased to physiological values (less than 13.3 kPa), with a low normal PaCO2 (less than 5.3 kPa), the decrease in ...
