Comparative StudyDetermination of cardiac output during mechanical ventilation by electrical bioimpedance or thermodilution in patients with acute lung injury: effects of positive end-expiratory pressure.
To evaluate the usefulness of transthoracic electrical bioimpedance in sedated and paralyzed patients with acute lung injury during mechanical ventilation with and without early application of positive end-expiratory pressure (PEEP). ⋯ In patients with acute lung injury: a) the agreement between TEB-CO and TD-CO measurements is poor; b) agreement is not clinically improved by application of PEEP; and c) TEB cannot monitor trends in CO.

Multicenter Study Comparative Study Clinical TrialA multicenter evaluation of a new continuous cardiac output pulmonary artery catheter system.
To validate a new system of continuous cardiac output monitoring. ⋯ This continuous cardiac output system provides a reliable estimate of cardiac output for clinical use if applied in conditions similar to this study. The combination of a continuous measure of cardiac output with other continuous physiologic monitoring (arterial and mixed venous oxygen saturation, oxygen consumption, etc.) may provide important information that no single parameter could achieve.

Comparative StudyNo difference exists in the alteration of circadian rhythm between patients with and without intensive care unit psychosis.
To determine if a difference exists in the circadian rhythm entrainment between patients with and without intensive care unit (ICU) psychosis. ⋯ Either patients who develop ICU psychosis have an increased sensitivity to an alteration of their circadian rhythm, or ICU psychosis develops independent of circadian rhythm abnormalities.
