Multicenter Study Comparative Study
[Non-invasive evaluation of pulmonary artery occlusion pressure in critically ill patients with mechanical ventilation].
To compare the measurements of pulmonary artery occlusion pressure (PAOP) by means of the use a pulmonary artery catheter and those obtained through a formula that relates the systolic artery pressure before and after a Valsalva maneuver. ⋯ The prediction of the PAOP by means of the Valsalva maneuver showed a limited correlation with that obtained by means of the pulmonary artery catheter.
