Where PIP = peak inspiratory pressure ( the maximum pressure during inspiration ), and PEEP = positive end expiratory pressure.
12.
If it is caused by expiratory muscles, it will add an elastic load and it will increase the operating lung volume.
13.
The test, known as an FEV, for forced expiratory volume, measures how much air someone can exhale in one second.
14.
Testing peak expiratory flow is more variable than spirometry, however, and thus not recommended for routine diagnosis . < ! --
15.
The level of pressure relief is varied based on the patient s expiratory flow, making breathing out against the pressure less difficult.
16.
The generation and modulation of eupnea and the transition between the inspiratory and expiratory phases have also been implicated in respiratory rhythm generation.
17.
It involves testing with methacoline, after which the forced expiratory volume in 1 second ( FEV 1 ) of the patient is measured.
18.
In this case, the individual s peak expiratory flow rate ( PEFR ) is measured, showing how fast a person can exhale.
19.
Breathing out against the positive pressure resistance ( the expiratory positive airway pressure component, or EPAP ) may also feel unpleasant to some patients.
20.
In cats, after anaesthesia and bivagotomy, pontine transection has been described as evoking a long sustained inspiratory discharges interrupted by short expiratory pauses.
