positive pressure respiration

In amphibians, the process used is positive pressure breathing.

"But the big thing is that pilots can talk at 8 or 9 G's, which is difficult when using a positive pressure breathing system," he said.

The suit uses a positive pressure breathing system, so it is even capable of being used in a chemical- or biological-warfare environment."

Respiratory treatments (chest physiotherapy, intermittent positive pressure breathing inhalers, or nebulizer treatments).

Intermittent positive pressure breathing (Physiotherapy)

Intermittent positive pressure breathing (IPPB) is a respiratory therapy treatment for people who are hypoventilating.

Intermittent positive pressure breathing (IPPB)Physiotherapy has long been used in the intensive care setting in non-intubated patients.

Acetylcysteine solution can be inhaled directly from the nebulizer, or with a face mask, mouth piece, tent, or intermittent positive pressure breathing (IPPB) machine.

To ease the strain of this maneuver and to aid breathing, researchers developed a technique called positive pressure breathing, which involves forcing pressurized air into a pilot's lungs through a face mask.

One kind of ventilator is called an intermittent positive pressure breathing unit; it puts compressed gas into the lungs until a preset pressure is reached, then allows passive exhalation through a valve.

Subjects still use the anti-G breathing maneuver in high-G situations, he said, but it is not as stressful as with conventional anti-G suits and they can converse normally without positive pressure breathing interfering.

The Royal Australian Navy uses the Open Circuit Compressed Air Breathing Apparatus (OCCABA), a backpack-style, positive pressure breathing apparatus, for fire-fighting roles.
