What You’ll Need Before You Start
Before your first night on BiPAP, ensure you have:
- BiPAP machine (with power adapter)
- Prescribed mask (full-face, nasal, or nasal pillow)
- Humidifier chamber filled with distilled water only
- Standard or heated tubing connected to machine and mask
- Your prescription settings confirmed by your physician or sleep specialist
- A pulse oximeter to monitor your SpO₂ during the first few nights
Step-by-Step: Setting Up Your BiPAP Machine
Step 1 — Position the Machine
Place the BiPAP on a firm, flat surface at or below bed level. Keep at least 30cm of clearance on all sides for ventilation. Never place it on carpet or soft surfaces that can block the air intake.
Step 2 — Fill the Humidifier
Remove the humidifier chamber and fill to the MAX line with distilled water. Never use tap water — mineral deposits damage the chamber and can introduce bacteria. Reattach securely.
Step 3 — Connect the Tubing
Attach one end of the tubing to the machine’s air outlet and the other end to your mask. If using heated tubing, connect the power cable to the machine’s heated tube port.
Step 4 — Fit Your Mask
Put the mask on before lying down. Adjust headgear straps so the mask is snug but not tight — you should not feel pressure marks after 10 minutes. A small amount of air movement around the edges is normal; a large leak is not.
Step 5 — Start the Machine
Press the power button. Most machines start at a low “ramp” pressure and gradually increase to your prescribed IPAP/EPAP levels over 20–45 minutes, making it easier to fall asleep.
Step 6 — Breathe Normally
Relax and breathe at your natural pace. The machine will sense your breathing effort and deliver the correct pressure on inhalation (IPAP) and a lower pressure on exhalation (EPAP). Do not try to control your breathing — let the machine follow you.
Understanding Your BiPAP Settings
| Setting | What it means |
|---|---|
| IPAP | Pressure delivered when you inhale — keeps the airway open |
| EPAP | Lower pressure when you exhale — makes breathing out easier |
| Pressure support | The difference between IPAP and EPAP — typically 4–10 cm H₂O |
| Ramp time | Minutes the machine takes to reach full pressure from a low start |
| BPM (backup rate) | On ST mode — minimum breaths per minute delivered if you stop breathing |
Never adjust your IPAP or EPAP settings yourself. Changes must be made by your physician based on therapy data and clinical assessment.
Nightly Routine
- Fill humidifier with fresh distilled water (empty and refill — do not top up)
- Wipe mask cushion with a damp cloth to remove skin oils
- Check tubing connections are secure
- Start machine and fit mask before lying down
- Check your SpO₂ with a pulse oximeter in the first 15 minutes — target 90–95%
Weekly Cleaning Routine
| Component | Cleaning method | Frequency |
|---|---|---|
| Mask cushion & frame | Warm water + mild soap; air dry | Weekly |
| Headgear | Warm water + mild soap; air dry | Weekly |
| Tubing | Warm water + mild soap; hang to dry | Weekly |
| Humidifier chamber | Warm water + mild soap; air dry completely | Weekly |
| External foam filter | Rinse under warm water; air dry | Weekly |
| Machine exterior | Wipe with dry cloth | Weekly |
Never use alcohol, bleach, or scented soaps — these degrade silicone mask components and can irritate airways.
Troubleshooting Common Problems
Mask Leaks Air Loudly
Readjust headgear — tighten gradually, one strap at a time. Check mask cushion for cracks or wear; replace if needed. Ensure mask size is correct — try a different size or style.
Difficulty Exhaling Against Pressure
Ask your physician about increasing pressure support. Enable the EPR (Expiratory Pressure Relief) or C-Flex feature if available. Extend ramp time to allow slower pressure build-up.
Dry Mouth or Nose
Increase humidifier temperature setting. If using a nasal mask, add a chin strap to prevent mouth breathing. Consider switching to a full-face mask.
Condensation (“Rainout”) in Tubing
Upgrade to heated tubing. Reduce humidifier temperature slightly. Keep the machine at or below bed level so condensation drains back.
Skin Marks or Pressure Sores from Mask
Loosen headgear — over-tightening is the most common cause. Try mask liners. Consider a different mask style such as nasal pillow if using full-face.
Machine Alarm or Error Code
Consult your machine’s user manual for the specific code. Common causes: blocked air intake filter, disconnected tubing, low water in humidifier. Contact your supplier if the alarm persists.
When to Call Your Doctor
Contact your physician or sleep specialist if:
- Your SpO₂ consistently reads below 88% during therapy
- You wake frequently despite using the machine
- You experience chest pain, palpitations, or worsening breathlessness
- Your machine’s AHI data shows consistently above 5 events/hour
- You develop skin breakdown or pressure sores from the mask
- You feel no improvement after 4 weeks of consistent use (6+ hours/night)
Travelling with Your BiPAP Machine
- Always carry the machine as cabin baggage — never check it in
- Carry your prescription and a letter from your physician (required at some airports)
- Most modern BiPAP machines are dual-voltage (100–240V) — check before travelling internationally
- Carry a universal power adapter and a spare set of filters
- For areas without power, check if your machine supports DC/battery operation

Frequently Asked Questions
How many hours per night should I use my BiPAP?
A minimum of 6 hours per night is recommended for effective therapy. Most guidelines consider 7+ hours optimal. Consistent nightly use produces the best long-term outcomes.
Can I use my BiPAP machine while sitting up or napping?
Yes — BiPAP can be used in any position. Some patients use it during daytime naps or while watching TV. Ensure the mask fits well in your chosen position.
What if I accidentally swallow air (aerophagia)?
Aerophagia (air swallowing causing bloating or belching) is common at higher pressures. Inform your physician — they may adjust your EPAP setting or recommend a positional change.
Is it safe to use a BiPAP machine during a cold or blocked nose?
A blocked nose makes mask breathing difficult. Use a nasal decongestant (as advised by your doctor), increase humidifier temperature, or temporarily switch to a full-face mask. Do not stop therapy without medical advice.
My machine shows high leak rate — is this dangerous?
High leak rates reduce therapy effectiveness. Check mask fit and cushion condition first. If leaks persist, contact your supplier for a mask fitting review.
