NCT01011647

Brief Summary

A novel technique in identifying unspecified sleep apnea has been developed. This technique uses signals typical acquired from a bedside monitor that is found in critical care environments. Those signals are then processed by a sleep analysis algorithm to provide an Apnoea Hypopnea Index (AHI) score. This study is intended to determine whether the prevalence of sleep disordered breathing identification among patients in a Coronary Care Unit (CCU) using this novel approach is significantly different than using routine techniques.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Subject selection will come from patients admitted to the hospital with an acute cornonary condition.

You may qualify if:

  • Age equal to or greater than 18 years at time of consent
  • Written informed consent
  • Patients admitted to the intensive care unit if able to remove oxygen
  • Patients admitted to telemetry and step-down floor that will not require oxygen
  • Primary diagnosis (any of the following)
  • Un-stable angina
  • Acute myocardial infarction
  • Congestive heart failure

You may not qualify if:

  • Previously diagnosed sleep disordered breathing
  • Inability to consent
  • Pregnancy
  • Intubation (no longer excluded after extubation)
  • Oxygen therapy (no longer excluded after therapy ends)
  • End-Stage renal disease
  • End-Stage liver disease
  • Terminal disorders other than cardiac
  • Severe scoliosis
  • Cervical spinal cord injuries
  • Neuromuscular disorders
  • Severe COPD as defined by prescription of home oxygen therapy
  • Other unsuitable circumstances
