Selecting the appropriate sleep study

Laboratory vs Ambulatory Sleep Studies

The following patients may be considered for an ambulatory sleep study:
 

• Patients with a high pre-test probability of moderate to severe OSA.

• Patients with no significant co-morbid medical condition.  Examples of co-morbid conditions include moderate-severe pulmonary diseases (cystic fibrosis, pulmonary fibrosis, active asthma, COPD), congestive heart failure and neuromuscular diseases (ALS, multiple sclerosis, Parkinson’s disease).

• Patients suspected of having no co-morbid sleep disorder other than OSA.

• Patients unable to be undergo a PSG.

• To monitor response to non-CPAP treatments after the diagnosis has already been made.
