1.   Made by companies including Respironics and ResMed, Nellcor Puritan Bennett Inc. and Healthdyne, CPAPs deliver a steady stream of pressurized air which holds the airway open.

2.   Normally, valves and ducts in the air-conditioning system keep the pressurized air in the cabin.

3.   The others remained tethered to a pressurized air supply that assisted their immature lungs.

4.   The only electricity it uses produces pressurized air for the pipes.

5.   The system draws pressurized air from the engines and delivers it to the cabin.

6.   The tennis ball is one of the few products for which both the object and its packaging contain pressurized air.

7.   Air springs are reinforced rubber products that utilize enclosed pressurized air to cushion and control vehicle ride and reduce vibration in industrial equipment.

8.   Children given slightly pressurized air improved just as much as those treated in high-pressure oxygen chambers, the study found.

9.   Even the slightly pressurized air increased the concentration of oxygen in the blood.

10.   Pressurized air could have drained the hull to make it rise.
