Non-invasive ventilation devices provide breathing support for people in whom a doctor considers them appropriate. Being prescribed a device, however, does not mean it will be used regularly.
A familiar picture in practice: the device sits at home but is not used. The reasons are usually not technical but about tolerance — the mask feels uncomfortable, the skin becomes irritated, the mouth dries out, breathing does not fall into step with the device, the mask feels claustrophobic, or sleeping through the night with it seems impossible.
The role of physiotherapy here is not to change device settings; those are determined only by a doctor. Physiotherapy works on coordinating breathing with the device, building mask tolerance gradually and helping the routine settle into daily life.
What makes tolerance difficult
- Skin irritation and pressure marks at the mask edges
- Air escaping into the eyes because of a leak
- Dryness of the mouth and throat
- A sense of mismatch between the device and one's own breathing rhythm
- Claustrophobia and mask-related anxiety
- Abdominal bloating
- Removing the mask during the night, unable to use it until morning
Some of these relate to device settings or mask type and should be reported to your doctor. Others relate to the adaptation process and technique; that is where physiotherapy works.
A graded approach to adaptation
Aiming to use the device all night from the first night usually ends in failure. A graded plan is followed instead:
- First, simply placing the mask on the face with the device off, for short periods
- Then short trials with the device on, during the day while awake
- Calm, regular breathing work during those trials, aimed at reducing panic
- Increasing the duration in line with tolerance
- Moving to overnight use as the final stage
Difficulties along the way are noted and shared with your doctor; if the mask type or device settings need changing, that decision belongs to your doctor.
What physiotherapy covers — and does not
Covers: coordinating breathing with the device, a graded plan to build mask tolerance, breathing work for anxiety management, airway clearance alongside device use, positioning, keeping a usage diary and carer training.
Does not cover: setting or changing device pressures, deciding whether a device is indicated, adjusting oxygen flow rates. All of these are the doctor's responsibility.
The information on this page is for general guidance and does not replace individual advice. A physiotherapist does not diagnose; they assess and plan a programme within the framework of medical referral. Which techniques are suitable for you is determined through a face-to-face respiratory assessment. Please consult your doctor and physiotherapist before starting.
Sudden or rapidly worsening breathlessness, chest pain, bluish discolouration of the lips or nails, or confusion may signal an emergency. Do not attempt exercises in such a situation; call the emergency number (112 in Türkiye) or go to the nearest emergency department without delay.
Frequently Asked Questions
No. Device settings are determined and changed only by your doctor. If you are uncomfortable, tell your doctor; changing settings yourself can be harmful.
Before giving up, it is worth trying a graded adaptation plan. A significant share of tolerance problems improve with a change of mask type, correct fitting and gradual acclimatisation. If the problem persists, speak to your doctor — the answer is to look for a solution rather than to stop using it.
Breathing work can be planned for times when the device is not in use. Anything to be done alongside the device is planned carefully and within the framework set by your doctor.
