forced expiratory volume meaning in Hindi

Examples

1. The test, known as an FEV, for forced expiratory volume, measures how much air someone can exhale in one second.
2. It involves testing with methacoline, after which the forced expiratory volume in 1 second ( FEV 1 ) of the patient is measured.
3. COPD is defined as a forced expiratory volume in 1 second to forced vital capacity ratio ( FEV1 / FVC ) that is less than 0.7.
4. In COPD, there is an increase in airway resistance, shown by a decrease in the forced expiratory volume in 1 second ( FEV1 ) measured by spirometry.
5. Further evaluation of a person's respiratory function can be done by assessing the minute ventilation, forced vital capacity ( FVC ), and forced expiratory volume ( FEV ).
6. _Forced expiratory volume, which measured the amount of air expired in one second after taking a deep breath and breathing out as hard and fast as possible, provided an indication of the degree of airway obstruction.
7. Airflow obstruction not ascribable to other cause is labeled bronchiolitis obliterans syndrome ( BOS ), confirmed by a persistent drop three or more weeks in " forced expiratory volume " ( FEV 1 ) by at least 20 %.
8. Decreases in Forced Expiratory Volume in 1 s ( FEV1 ) after allergen challenge after 4 weeks of inhalation of pitrakinra supports the hypothesis that dual inhibition of IL-4 and IL-13 can affect the course of the late asthmatic response after experimental allergen challenge.
9. Average values for forced vital capacity ( FVC ), forced expiratory volume in 1 second ( FEV1 ) and forced expiratory flow 25 75 % ( FEF25 75 % ), according to a study in the United States 2007 of 3, 600 subjects aged 4 80 years.
10. On spirometry, as a restrictive lung disease, both the FEV1 ( forced expiratory volume in 1 second ) and FVC ( forced vital capacity ) are reduced so the FEV1 / FVC ratio is normal or even increased in contrast to obstructive lung disease where this ratio is reduced.
