Families are often told a patient needs "BiPAP" or "ventilator support" and may not know what this means. This guide explains BiPAP vs CPAP and how they differ from a ventilator.
Quick answer: BiPAP, CPAP and ventilator
- CPAP gives one steady pressure to keep the airway open.
- BiPAP gives two pressures — higher when breathing in, lower when breathing out.
- Both are usually given through a mask (non-invasive).
- A ventilator can fully take over breathing, usually through a breathing tube.
Comparison
| Feature | CPAP | BiPAP | Mechanical ventilator |
|---|---|---|---|
| How it works | Single continuous pressure | Two pressures: inhale and exhale | Delivers breaths; can fully control breathing |
| Interface | Mask | Mask | Usually a breathing tube |
| Common uses | Obstructive sleep apnoea; some hospital uses | COPD flare-ups with high carbon dioxide; some respiratory failure | Severe respiratory failure or when non-invasive support is not enough |
| Setting | Home or hospital | Hospital, sometimes home | ICU |
What patients may feel
Mask-based support can feel strange at first, with air pressure and mask tightness. Staff adjust fit and settings to improve comfort. On a ventilator, patients are usually given medicines to stay comfortable.
Decisions are individual
Which support is used depends on the patient's condition, test results and response to treatment. Kamla Multispeciality Hospital in Tagore Town, Prayagraj states that it provides ventilator, BiPAP and CPAP management; the critical-care team, including Dr. Rakesh Singh Maurya, explains choices to families.
