Sleep Report Comments

Oxygen saturation remained ≤88% for more than 5 minutes after AHI was reduced to ≤10, meeting CMS criteria for supplemental oxygen entrainment.

Supplemental oxygen was initiated per CMS guidelines after qualifying criteria were met.

Oxygen saturation did not fall ≤88% for a sustained period; supplemental oxygen criteria were not met.

The patient's baseline oxygen saturation was reduced prior to sleep onset, which was noted and considered when interpreting desaturation events.

Supplemental oxygen was continued at __ L/min throughout the remainder of the study following initiation.

CPAP titration was limited to __ cmH₂O due to fragmented sleep and poor tolerance.

Sleep efficiency during the treatment portion of the split-night study was markedly reduced at __% .

CPAP at the achieved pressure did not adequately treat the patient's apnea.

Bi-level therapy was attempted but was less well tolerated compared to CPAP.

Escalation of pressure resulted in an increased frequency of central apneas, suggestive of pressure-induced (complex/treatment-emergent) central sleep apnea.

PAP therapy was not initiated per ordering provider instructions.

PAP therapy was not initiated per protocol, as the study was ordered as a full-night diagnostic PSG followed by MSLT.

An optimal titration pressure could not be determined due to insufficient sleep time during the treatment portion of the study.

The patient demonstrated good tolerance of CPAP at __ cmH₂O with significant reduction in respiratory events.

During the diagnostic portion of the study, the patient's breathing pattern demonstrated features suggestive of Cheyne–Stokes respiration.

Snoring, PLMs, and respiratory events could not be adequately assessed due to insufficient observed sleep.

The majority of respiratory events were positional, occurring predominantly in the supine position.

Respiratory events were most frequent during REM sleep, consistent with REM-related obstructive sleep apnea.

Central apneas predominated, with few obstructive events identified during the diagnostic portion of the study.

This study was performed as a full-night diagnostic PSG followed by MSLT, per the ordering provider.

The patient met criteria for MSLT, and the study was performed as scheduled.

Caffeine and stimulating medications were held prior to and during the MSLT per protocol.

The patient was unable to tolerate CPAP due to claustrophobia. Multiple mask interfaces were attempted without success.

At the patient's request, the titration study was terminated early and the patient left the sleep center. An Early Termination form was signed.

Due to less than 6 hours of technically adequate recording time, Modifier -52 (Reduced Services) was applied.

Total sleep time was insufficient to complete a valid study. Results should be interpreted with caution.

The study was technically limited by frequent artifact due to patient movement/lead displacement.

REM sleep was not achieved during this study; REM-related respiratory events and sleep architecture cannot be fully assessed.

The patient was unable to fall asleep during the study. No scorable data were obtained.
