What's a Ventilator and What Does It Do?

7. Ventilator vs. Respirator

A ventilator differs significantly from a respirator, though many people incorrectly use the terms interchangeably. A respirator is a protective face mask that does not assist with breathing. Instead, it helps prevent the inhalation of harmful airborne particles such as dust, chemicals, and viruses. N95 masks are respirators healthcare workers often use when in close contact with infected patients and people with compromised immunity.
