Overnight Pulse Oximetry

This is a non-invasive, less expensive alternative to a complete overnight sleep study. The patient is fitted with a small wrist oximeter that is to be worn  at night (at least 4 hours for best results). It tests for oxygen levels and heart rate. Test is typically ordered for the following conditions:

  • Suspected sleep apnea
  • Poor sleeping patterns
  • Adequacy of current oxygen
  • Continuous positive airway pressure (CPAP) therapy
  • Bi-level positive airway pressure (BIPAP) therapy 
  • Assess baseline breathing for further testing 
  • Qualify for home oxygen
