Pre-existing variables and outcome of cardiac arrest resuscitation in hospitalized patients.

If critical care nurses and advanced practice nurses could identify patients with an increased risk of an unsuccessful outcome from cardiac arrest resuscitation in the hospital, such patients could be monitored with a heightened vigilance. This is the first nursing study to examine pre-existing variables and outcome of cardiac arrest resuscitation in hospitalized patients. The investigators found that heart rate and respiratory rate increased significantly 8 hours before the cardiac arrest in patients with an unsuccessful outcome of resuscitation.
