Current Primary Outcome Measures
 (submitted: September 4, 2012)
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.
Original Primary Outcome Measures
 (submitted: March 5, 2010)
Prevalence of saturation patterns indicative of repetitive reductions in airflow [ Time Frame: Five Nights ]
Change History Complete list of historical versions of study NCT01082575 on Archive Site
Current Secondary Outcome Measures
 (submitted: September 4, 2012)
Number of Participants With Adverse Events (AE) Caused by no Breathing [ Time Frame: Five Nights ]
Number of participants with Airway Obstruction that caused the patient to stop breathing Number of participants with Cardiac arrest w/resuscitation caused by the patient not breathing
Original Secondary Outcome Measures
 (submitted: March 5, 2010)
Determine whether the occurrence of saturation patterns indicative of repetitive reductions in airflow is associated with post-operative adverse events [ Time Frame: Five Nights ]

Descriptive Information
Brief Title Oxygen Monitoring of Patients After Surgery on the Hospital General Care Floor
Official Title Oxygen Saturation Monitoring in the General Care Floor (GCF): An Observational Study of Repetitive Reductions in Airflow
Brief Summary 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.
