If you’ve just started CPAP therapy and the airflow feels overwhelming — even at a “low” pressure setting — you’re not alone, and it doesn’t necessarily mean the machine is wrong for you. Adjusting to positive airway pressure therapy is widely recognized as one of the hardest parts of getting used to treatment, and there are several well-documented reasons the first nights can feel so intense, along with strategies that may help.
Why the pressure can feel unbearable at first
According to the American Academy of Sleep Medicine (AASM), it’s common for new CPAP users to feel like they “can’t breathe out” against the incoming air, even when the prescribed pressure is objectively low. This sensation tends to ease as the body adjusts, but that adjustment period can genuinely feel torturous in the moment, especially for someone trying it for the very first time.
The Sleep Foundation notes that mask type matters too: nasal-only masks and nasal pillow masks direct all of the airflow through a smaller area, which some people experience as more intense than a full-face mask, even at the same pressure. Nasal dryness, congestion, or a mask that isn’t sealing quite right can also make the sensation feel worse than it needs to be.
What may help while you wait to talk to your provider
- Use the ramp feature if your machine has one — most modern CPAP machines, including ResMed AirSense models, include a ramp setting that starts at a much lower pressure and gradually increases over several minutes as you fall asleep, according to ResMed’s own patient guidance and echoed by sleep clinics generally.
- Check humidification settings — the Sleep Foundation notes that a dry, high-pressure airstream can feel harsher than a properly humidified one; increasing the humidity level (if your machine has an integrated humidifier) may make the airflow feel gentler.
- Practice while awake, during the day — several sleep clinics recommend wearing the mask and running the machine for short stretches while awake and relaxed, before trying to sleep in it, to help the nervous system get used to the sensation without the added stress of trying to fall asleep at the same time.
- Reassess mask fit and type — a mask that’s slightly too loose or too tight can make the same pressure setting feel more intense; a different mask style (nasal pillow vs. full face vs. nasal) genuinely feels different to different people, and switching styles is a normal part of finding the right fit.
When to reach out to your care team
If the discomfort is severe enough that you can’t tolerate the mask at all, most sleep medicine guidance is clear that you shouldn’t just tough it out alone for weeks — most CPAP suppliers and sleep clinics have a nurse line, on-call clinician, or triage system for exactly this kind of early-adjustment issue, even outside of standard scheduling. It’s worth asking your equipment provider whether they have an after-hours or urgent contact option, since pressure and comfort settings can often be adjusted remotely once a clinician reviews your case.
Struggling in the first few nights is extremely common and doesn’t mean CPAP therapy won’t work for you long-term — most people who stick with adjusting mask fit, pressure ramp, and humidity settings do find a setup that’s tolerable, even if the very first night felt discouraging.
