expiratory

relating to or employed in the expiration of air from the lungs.

expiratory center
the nerve center in the descending reticular formation which terminates inspiration and triggers the commencement of expiratory movements.
expiratory groan
a groan with each expiration; usually an expression of severe pain or extreme fatigue.
expiratory reserve volume
the volume of air which the patient can still exhale after the tidal volume has been exhaled.

Expiratory and inspiratory respiratory variables in all three groups are shown in Table 2.
5] Hence, the present study is taken up to study correlation of BMI and flow rates (forced expiratory flow 25-75% [FEF 25-75%], FEF 75%, peak expiratory flow [PEF], and maximal voluntary ventilation [MVV]) of pulmonary function test in controls and patients.

The ratio of the forced vital capacity (FVC) that is not yet expired within the first 3 seconds of a forced exhalation is expressed with the following formula: 1 minus-forced expiratory volume in third seconds (1-[FEV.
Peak Expiratory Flow Rate (PEFR) recorded on Wrights peak flow meter is commonly used for screening individuals with chronic airway obstruction both in clinical and in field studies.
The active use of the expiratory muscles (as during exercise) can produce auto-PEEP with normal or even subnormal end-expiratory lung volumes.
The forced expiratory volume is the amount of air expelled in the first second as part of the FVC maneuver after maximal inhalation.
In addition, there was a significantly negative correlation between plasma CTGF levels in patients with asthma and forced vital capacity (FVC), FEV1, percentage of predicted FEV1, FEV1/FVC ratio, forced expiratory flow at 50% of the FVC (FEF50%), percentage of predicted FEF50%, forced expiratory flow at 75% of FVC (FEF75%) and percentage of predicted FEF75% parameters, which show the degree of airway obstruction.
In patients with spontaneous respiration, a significant relationship was found between IVC diameters measured by ultrasonography at the end of expiratory and inspiratory phases and measured CVP values at the same phases (for expiratory p = 0.
Positive Expiratory Pressure (PEP) therapy involves the application of a resistance to expiration in order to produce positive airway pressure (Darbee et al 2004).
We measured the Peak Expiratory Flow Rate ( PEFR), the rate at which a person exhales, to assess lung function.
