临床上动脉血气分析包括病人pH,PaCO_2(动脉二氧化碳分压),HCO_3~-(碳酸氢盐)的波动,反映了人体酸硷平衡状况。这些指标可能在很短时间内完全正常的,但可以在很短时间内突然异常。本文建议采取四个步骤进行分析。这四步法既快速,又简单实用。步骤1:掌握每一数据的正常值及其意义例如,一病人pH值7.35;PaCO_264mmHg;HCO_3~-33mEq/L。下文分析这一组数据。若pH值7.35,应该说酸硷是平衡的,因为pH正常值在7.35—7.45之间。pH值反映了体内氢离子的浓度,它是体内血液酸硷平衡的重要指标之一。一个低的pH值意味着H~+的增多表示酸性;一个高的pH值意味着硷性。
Clinical arterial blood gas analysis including patient pH, PaCO_2 (arterial partial pressure of carbon dioxide), HCO_3 ~ (bicarbonate) fluctuations, reflecting the human acid-base balance. These indicators may be completely normal in a very short period of time, but can suddenly abnormalities in a very short period of time. This paper suggests four steps for analysis. This four-step method is fast, simple and practical. Step 1: Grasp the normal value of each data and its significance For example, a patient pH 7.35; PaCO_264mmHg; HCO_3 ~ -33mEq / L. The following analysis of this set of data. If the pH is 7.35, it should be said that the pH is balanced as the normal pH is between 7.35 and 7.45. pH value reflects the concentration of hydrogen ions in the body, which is one of the important indicators of the blood acid-base balance in the body. A low pH means that an increase in H + indicates acidity; a high pH means alkalinity.
