A Internal Positive Pressure aid is an artificial aid for breathing used if you have problems with your muscles or lungs.

Our bodies have an internal pressure equal to that of the atmosphere (101000 pascals). Once the external pressure on you body exceeds this internal pressure enough your body will implode. This external pressure can be provided by water. Depending on how you go about going that far below water and the specific tolerances of your body a deadly depth can be from 500 to 1200 feet.
PVC - Positive Crankcase Ventilation. Used to allow the engine to vent out pressure that is creates while operating. Generally it is vented back into the air intake system after the air filter to get "burned" in the combustion chamber.
Transducer (i.e. a device for converting energy from one form to another) for both vacuum and positive pressure.
I guess it depends on whether it's sealed or not. If it's open to the atmosphere how can it be under pressure ? If it's sealed it could be put under (positive or negative) pressure so would be, by definition, a pressure vessel IMHO.
The internal water pressure in plants is countered by the cell wall. This is called turgor pressure.
points in your body that hurt when pressed or when pressure is applied.
Pressure Shaft is designed to resist Internal as well as External Pressure, but the Penstock is designed to resist Internal Pressure only. - Saravanan.S
external/ internal intercostals
It can be either.

The internal pressure of the lungs is controlled by the diaphragm and the muscles of the thorax (chest). Inhalation is caused by increasing the volume (which lowers the internal pressure) while decreasing the volume (increases the internal pressure) leads to exhalation, similar to the way a bellows works. The elastic qualities of the lung also help the process of exhalation.
The complication that is usually associated with the positive-pressure ventilation is that the lung can be injured.
