During an overnight sleep study, a patient is noted to have apneic episodes, desaturation, and no airflow; but the patient’s thoracic cavity is moving.

What device would you trial the patient on for treatment?
  1. Oxygen 2 L/min at hs
  2. Oxygen 4 L/min at hs
  3. CPAP
  4. Dopram
Explanation
Answer: C-If a patient’s thoracic cavity is moving without airflow the patient has obstructive sleep apnea and should be titrated on CPAP.

Saturations might improve with positive air pressure at night; but if saturations do not improve, they should be titrated with oxygen as well. If there was an absence of thoracic activity during apneic episodes, the patient would be a central sleep apnea patient and trialed on a respiratory stimulant such as Dopram.
