Acute physiology and chronic health evaluation (APACHE II) scoring in a cardiothoracic intensive care unit.
To evaluate the predictive value of the Acute Physiology and Chronic Health Evaluation (APACHE II) scoring system in cardiothoracic surgical patients. ⋯ There was a good relationship between the APACHE II score and mortality rate. Low APACHE II scores accurately predicted survival but only very high scores accurately predicted death.

Gastric tonometry and venous oximetry in cardiac surgery patients.
To determine the relationship between gastric intramucosal pH and several other indices of splanchnic perfusion in patients undergoing cardiopulmonary bypass. ⋯ Gastric intramucosal pH may provide a minimally invasive way to monitor the adequacy of splanchnic DO2 in patients undergoing cardiopulmonary bypass. Additional data are necessary to determine whether low gastric intramucosal pH is truly a marker of supply-dependent oxygen uptake across the hepatosplanchnic vascular bed under these conditions.

Comparative StudyMeasurement of alveolar ventilation and changes in deadspace by indirect calorimetry during mechanical ventilation: a laboratory and clinical validation.
To validate the assessment of changes in alveolar ventilation and deadspace by indirect calorimetry. ⋯ Changes in alveolar ventilation and deadspace can be accurately measured by combined use of indirect calorimetry and end-tidal CO2 analysis.
