The general public and the medical community have become increasingly
aware of the prevalence of, and morbidity and mortality associated wit
h, obstructive sleep apnea (OSA). This knowledge, recent technologic a
dvances, and other issues have led to an increase in the use of portab
le recording devices intended to diagnose OSA. The American Sleep Diso
rders Association's Standards of Practice Committee has developed thes
e practice parameters to guide the clinician in the appropriate use of
these portable recording devices.
