Что (кто) такое expiratory - определение

FLOW OF THE RESPIRATORY CURRENT OUT OF AN ORGANISM
Exhale; Exhaling; Exhaled; Passive expiration; Expiratory; Exhalant; Exhalent; Expirate; 😮‍💨; Expiration (breathing out)

Expiratory         
·adj Pertaining to, or employed in, the expiration or emission of air from the lungs; as, the expiratory muscles.
Positive end-expiratory pressure         
PRESSURE IN THE LUNGS ABOVE ATMOSPHERIC PRESSURE THAT EXISTS AT THE END OF EXPIRATION
Positive end expiratory pressure; Positive end-expiratory pressure valve; PEEP valve; Positive End Expiratory Pressure; Auto-PEEP; PEEP; Positive-end expiratory pressure; Positive End-Expiratory Pressure; Peep Valve
Positive end-expiratory pressure (PEEP) is the pressure in the lungs (alveolar pressure) above atmospheric pressure (the pressure outside of the body) that exists at the end of expiration. Citing: The two types of PEEP are extrinsic PEEP (PEEP applied by a ventilator) and intrinsic PEEP (PEEP caused by an incomplete exhalation).
Peak expiratory flow

  • Peak flow meter (made in USA)
Wright scale; Peak expiratory flow rate; Peak flow; Pefr; Peak expiatory flow rate; Peak Expiratory Flow; Peak Flow Meter; Peak flow meter
The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR), is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air. It measures the airflow through the bronchi and thus the degree of obstruction in the airways.

Exhalation

Exhalation (or expiration) is the flow of the breath out of an organism. In animals, it is the movement of air from the lungs out of the airways, to the external environment during breathing. This happens due to elastic properties of the lungs, as well as the internal intercostal muscles which lower the rib cage and decrease thoracic volume. As the thoracic diaphragm relaxes during exhalation it causes the tissue it has depressed to rise superiorly and put pressure on the lungs to expel the air. During forced exhalation, as when blowing out a candle, expiratory muscles including the abdominal muscles and internal intercostal muscles generate abdominal and thoracic pressure, which forces air out of the lungs.

Exhaled air is 4% carbon dioxide, a waste product of cellular respiration during the production of energy, which is stored as ATP. Exhalation has a complementary relationship to inhalation which together make up the respiratory cycle of a breath.
