WebThe process of moving air from the external environment into the lungs is called inspiration. Expiration is air moving from the lungs out of the body into the environment. As described previously, air will always move from a region of high pressure to a region of lower pressure. WebAn ineffective breathing pattern is a condition of inadequate ventilation due to an impairment in the mechanism of inspiration and expiration. Prolonged inadequate ventilation may lead to compromised respiratory function performance, such as providing oxygen to the tissues, removing waste products, and acid-base balance.
