What did ventilators used to be like?

They were giant cases (iron lung) from the neck to abdomen. Air was pumped out and pressure dropped making the lungs expand and air taken in. Air was pumped in which forced air out. They could changes blood flow in the abdomen.

What are new ventilators like?

They pump air into the lungs, expanding the ribcage and when the pumping stops, the ribcage relaxes pushing air out. It doesnt interfere with blood flow but could cause damage to the lungs if they cant cope with artificial air flow
