According to RECOMMENDED guidelines, portable monitoring is an appropriate choice for:

• A. Screening patients with a low probability of OSA
• B. Monitoring a patient's response to oral appliance therapy
• C. Assessing patients with low baseline oxygen saturation
• D. Diagnosing Hypoventilation Syndrome

Answer: (B)

Portable monitoring is best used to see how well a treatment works for a patient with suspected sleep apnea, because it provides objective data on breathing during sleep with the therapy in place. In the case of an oral appliance, you can compare post-therapy measures—such as the apnea-hypopnea index and oxygen desaturation index—to baseline data to determine if the appliance is effectively reducing obstructions. It’s not ideal for initial screening in someone with a low probability of OSA, since the test is most reliable when there is a higher pretest probability and it may miss other sleep disorders. It also isn’t suited for patients with low baseline oxygen saturations or when diagnosing a hypoventilation syndrome, because portable monitors typically lack comprehensive ventilation assessment and CO2 monitoring required to evaluate hypoventilation or problematic nocturnal hypoxemia.
