Various techniques for reading pulmonary artery and pulmonary capillary wedge pressures have been described. We feel that the most easily obtained and accurate method for reading pressures with respiratory variations should be with reference to end expiration. This is a relatively constant period of intrathoracic pressure and allows for a stable pressure waveform, which can be measured easily. No matter which technique is utilized, a standard procedure should be adopted by those reading the pressures and understood by those who must interpret them. Consistency in the method of pressure waveform reading is important to ensure meaningful measurements and subsequent appropriate treatment of the patient.
已经描述了多种读取肺动脉压和肺毛细血管楔压的技术。我们认为，读取随呼吸变化的压力时，最容易获得且准确的方法应该是参考呼气末。这是胸腔内压力相对恒定的时期，可产生稳定的压力波形，便于测量。无论采用哪种技术，读取压力的人员都应采用标准程序，且必须让解读这些压力的人员理解。压力波形读取方法的一致性对于确保获得有意义的测量结果以及随后对患者进行适当治疗非常重要。
