Number of General Care Floor Patients Exhibiting a Saturation Pattern Detection (SPD) Alert. [ Time Frame: 5 days ]
Number of patients on the General care Floor in which a SPD (Saturation Pattern Detection) Alert occurs. Each patient wore a sensor on their finger continuously after surgery for up to 5 days. The sensor was attached to a Nellcor N600X oximeter which measures blood oxygen level. A SPD alert detects a patient's blood oxygen level that is increasing and decreasing in a pattern that is associated with periods of no breathing.

Oxygen Monitoring of Patients After Surgery on the Hospital General Care Floor
Oxygen Saturation Monitoring in the General Care Floor (GCF): An Observational Study of Repetitive Reductions in Airflow
The pain medication given after major surgery may cause some patients to stop breathing for periods of time especially at night time. An oxygen monitor may reflect this abnormal breathing pattern. This is an observational study of 100 post-operative patients who will be monitored with a pulse oximeter for a minimum of two nights and a maximum of five nights to determine the prevalence of this abnormal breathing pattern.
No further details necessary or available.
