Ventilator vs BiPAP: what's right for home care?

Understanding the difference in support level, and when each device is recommended by doctors.

Both devices support breathing, but they are prescribed for very different levels of respiratory need.

What a ventilator does

A ventilator takes over some or all of the work of breathing for a patient. It is prescribed when a patient cannot maintain adequate breathing on their own.

What BiPAP/CPAP does

BiPAP and CPAP machines support breathing through a mask rather than replacing it — commonly used for sleep apnoea, COPD, or as a step-down device after ventilator weaning.

How the decision is made

This is always a clinical decision made by the treating doctor based on blood-oxygen levels, underlying condition, and the patient's ability to breathe independently.
