A machine that either helps you breathe or does it for you is called a ventilator.
A device that supports or takes over breathing is called a ventilator. A ventilator might be necessary for people who have severe COVID-19 symptoms.
One of the most common reasons patients were treated in intensive care units (ICUs) prior to the pandemic of COVID-19 was the need for ventilation. The need for ventilators has grown since then.
