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...
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...

Ninety per cent had PaO 2 and PaCO 2 values within the adult normal range, indicating that the sedation had little effect on ventilation and oxygenation regardless of age. Significantly lower pH and calculated base excess values were found in children under 12 years of age. This tendency to ...
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 ...
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 ...
Indications and Evaluations of Bilevel Positive Airway Pressure: An assessment of 10 cases Mean Borg perceived dyspnea scale, respiratory rate, pH, PaCO2, PaO2, and SaO2 significantly improved after the use of Bi-PAP. (Mean values of items ... K Kujime,Y Takeda,T Soma - 《Japanese Journal...
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...
