Indications for use parsed from FDA documents

The WatchPAT300 is a non-invasive home care device for use with patients suspected to have sleep related breathing disorders. The WP300 is a diagnostic aid for the detection of sleep related breathing disorders, sleep staging (Rapid Eye Movement (REM) Sleep, Light Sleep, Deep Sleep and Wake), snoring level and body position. The WP300 generates a peripheral arterial tonometry ("PAT") Respiratory Disturbance Index ("PRDI"), Apnea-Hypopnea index ("PAI"), Central Apnea- Hypopnea index ("PAHIc"), PAT sleep staging identification (PSTAGES) and optional snoring level and body position discrete states from an external integrated snoring and body position sensor. The WP300's PSTAGES and snoring level and body position provide supplemental information to its PRDI/PAHI/PAHIc. The WP300's PSTAGES and snoring level and body position are not intended to be used as the sole or primary basis for diagnosing any sleep related breathing disorder, prescribing treatment, or determining whether additional diagnostic assessment is warranted. PAHIc is indicated for use in patients 17 years and older. All other parameters are indicated for 12 years and older.

ChatPPG interpretation

A 510(k) decision of "substantially equivalent" means FDA found the device as safe and effective as a legally marketed predicate. FDA's word for this is cleared, not approved. The clearance covers the device and indications in this submission; it does not extend to other features or versions of the same product that were not part of it. See FDA cleared vs approved.

Product code MNR is "Ventilatory Effort Recorder", class 2, 21 CFR 868.2375.
