Pulmonary artery pressure measurement: state of the art.
The measurement of pulmonary artery pressure is a highly complex skill. Numerous technical variables can affect the reliability and validity of hemodynamic measurements: zeroing, referencing and evaluating the dynamic response characteristics of the pressure system, expected pressure fluctuations, stabilization period, and the effects of position and ventilation. This article presents a review of the literature related to the technical aspects of pulmonary artery pressure measurement. Recommendations for practice are presented in a research-based protocol.
