The purpose of the study was to describe the patterns of weaning from mechanical ventilation in young children recovering from acute hypoxemic respiratory failure. ⋯ Patterns of weaning are discernible in a population of young children and indicate a subset at risk for inconsistent weaning. Knowing the patterns of weaning may help clinicians anticipate, perhaps plot, and then modulate a patient's weaning trajectory.

Nursing care of patients with advanced heart failure with low ejection fraction requires strict management of IV fluids. Measurement of mixed venous oxygen saturation offers advantages over measurement of cardiac output because no administration of fluid is required and data are obtained continuously. ⋯ Similar correlations in the groups receiving and not receiving vasoactive medications suggest that even with pharmacological support, changes in mixed venous oxygen saturation may not be reflected by concomitant changes in cardiac output. Measurement of mixed venous oxygen saturation should not replace measurement of cardiac output for clinical decision making in patients with advanced heart failure with low ejection fraction.

12-lead ST-segment monitoring vs single-lead maximum ST-segment monitoring for detecting ongoing ischemia in patients with unstable coronary syndromes.
12-lead ECG monitoring of the ST segment is more sensitive than patients' symptoms for detecting ischemia after thrombolytic therapy or catheter-based interventions, but it is unclear whether monitoring of the single lead showing maximum ST deviation would be as efficacious. ⋯ Monitoring of all 12 ECG leads for changes in the ST segment is necessary to detect ongoing ischemia in patients with unstable coronary syndromes.
