Glossopharyngeal breathing (GPB, glossopharyngeal insufflation, buccal pumping, or frog breathing) is a means of pistoning air into the lungs to volumes greater than can be achieved by the person's breathing muscles (greater than maximum inspiratory capacity).
Buccal pumping is "breathing with one's cheeks": a method of ventilation used in respiration in which the animal moves the floor of its mouth in a rhythmic manner that is externally apparent. [1] It is the sole means of inflating the lungs in amphibians .
positive pressure breathing 1. (diving) Breathing when pressure of the breathing gas at the mouth exceeds the ambient pressure at the thorax. Can be caused by use of a positive pressure mask, upright position, chest mounted rebreather counterlung, or supine position with a twin-hose regulator. 2.
The application of positive pressure may be intended to prevent upper airway collapse, as occurs in obstructive sleep apnea, or to reduce the work of breathing in conditions such as acute decompensated heart failure. CPAP therapy is highly effective for managing obstructive sleep apnea.
The trachea begins at the lower edge of the cricoid cartilage of the larynx [3] at the level of sixth cervical vertebra (C6) [2] and ends at the carina, the point where the trachea branches into left and right main bronchi., [2] at the level of the fourth thoracic vertebra (T4), [2] although its position may change with breathing.

Positive pressure is a pressure within a system that is greater than the environment that surrounds that system. Consequently, if there is any leak from the positively pressured system, it will egress into the surrounding environment. This is in contrast to a negative pressure room, where air is sucked in.

Non-invasive ventilation (NIV) is the use of breathing support administered through a face mask, nasal mask, or a helmet.Air, usually with added oxygen, is given through the mask under positive pressure; generally the amount of pressure is alternated depending on whether someone is breathing in or out.
Intermittent positive pressure breathing (IPPB) is a respiratory therapy treatment for people who are hypoventilating. While not a preferred method due to cost, [ 1 ] IPPB is used to expand the lungs, deliver aerosol medications, and in some circumstances ventilate the patient.
