Comparative Study Clinical Trial Controlled Clinical Trial
ST segment monitoring with a derived 12-lead electrocardiogram is superior to routine cardiac care unit monitoring.
Prior studies have shown that a derived 12-lead electrocardiogram with a simple electrode configuration is comparable with the standard electrocardiogram for arrhythmia analysis. ⋯ The findings show that derived 12-lead ST monitoring is superior to routine monitoring of leads V1 and II for detecting transient myocardial ischemia. ST monitoring of the derived 12-lead electrocardiogram may identify high-risk patients with unstable angina and provide prognostic information that would not be otherwise available from the usual clinical measures.

Comparative Study
Endotracheal suctioning: ventilator vs manual delivery of hyperoxygenation breaths.
Despite a large number of studies on endotracheal suctioning, there is little data on the impact of clinically practical hyperoxygenation techniques on physiologic parameters in critically ill patients. ⋯ Using techniques currently employed in clinical practice, these findings support the use of the patient's ventilator for hyperoxygenation during suctioning.
