BiPAP for OHS
Advanced Respiratory Support for OHS.
Obesity Hypoventilation Syndrome (OHS) can cause daytime CO₂ retention and low blood oxygen, often alongside obstructive sleep apnea. When a sleep physician determines CPAP alone is insufficient, BiLevel-ST therapy — such as the Löwenstein Prisma 25ST — provides two independent pressures to assist ventilation.

How BiLevel-ST Therapy Helps OHS Patients
Dual Pressure Support
Independent IPAP/EPAP (4–25 hPa) assists ventilation more effectively than single-pressure CPAP in OHS.
Helps Address Hypoventilation
Pressure support can help manage the chronic CO₂ retention characteristic of OHS.
Supports Better Sleep
Consistent overnight therapy can improve sleep quality and reduce daytime sleepiness.
Automatic Safety Backup
autoBackup Frequency (PRIO S+) provides a backup breath if natural breathing pauses too long.
Who Can Benefit?
- Patients diagnosed with Obesity Hypoventilation Syndrome by a sleep or respiratory physician
- Those with confirmed daytime CO₂ retention alongside obesity
- Patients for whom CPAP alone has not adequately managed symptoms
- Individuals prescribed BiLevel-ST therapy following a titration study
About Obesity Hypoventilation Syndrome
OHS is a condition in which excess body weight impairs breathing mechanics enough to cause daytime hypoventilation — elevated CO₂ and low oxygen levels — frequently combined with obstructive sleep apnea. Diagnosis and therapy titration are done by a sleep physician, who determines whether CPAP or BiLevel-ST support is appropriate.
BiPAP Machine Settings — What You Can and Cannot Change
Pressures and the backup rate for obesity hypoventilation are prescribed by your physician and entered by a technician behind a clinician code. The settings you can reach are in the Comfort menu: autoSTART/STOP, mask test pressure, softSTART and softPAP. This walkthrough of the Löwenstein prismaLINE platform shows each one.
