FVC = VC FEV1 FVC och FEV1 beräknas från en forcerad maximal utandning FEV% beräknas som FEV1/VC där FEV1 är högst uppmätta och VC är max av VC

FEV1 is the volume of air that can forcibly be blown out in first 1 second, after full inspiration. Average values for FEV1 in healthy people depend mainly on sex and age, according to the diagram. Values of between 80% and 120% of the average value are considered normal.

Forced vital capacity (FVC) is the total amount of air exhaled during the FEV test. Forced expiratory volume and forced vital capacity are lung function tests that are measured during spirometry. We analyzed the FEV1/FEV6 and FEV1/FVC results of 502 consecutive patients in the spirometric diagnosis of airway obstruction. We also examined the agreement between FEV6 and FVC in the spirometric Citation: Majid Mirsadraee ,Elnaz Salarifar ,Davood Attaran , Evaluation of superiority of FEV1/VC Over FEV1/FVC for classification of pulmonary disorders, J.

Welty et all6 studied a randompopulationof171 adultsandfoundno statistically significant association between challenge test) and pulmonary function after adjusting for smokinghabits. The small decrease of FEVI/VC% in our symptomatic subjects had no effect on bronchial hyperreactivity.

The FEV1 and VC both provide quite different information about a patient’s lungs. Unfortunately, spirometry as it is currently practiced is optimized towards generating an accurate FEV1 more than an accurate VC. This is partly due to limitations in the maneuver itself and partly due to the lack of accurate end-of-test criteria for an adequate VC. Die Abkürzung FEV1/VCmax steht für einen bestimmten Wert, den der Arzt bei einer Untersuchung der Lungenfunktion berechnet. Mit diesem Wert kann der Arzt vor allem feststellen, ob die Atemwege verengt sind. Um den Wert zu bestimmen, muss der Patient zunächst so tief wie möglich einatmen. Keep in mind, however, that some of the above data are based on the pre-thorascopy and pre-epidural eras, and may no longer be as applicable.

It represents the proportion of a person's vital capacity that they are able to expire in the first second of forced expiration (FEV1) to the full, forced vital capacity (FVC). The result of this ratio is expressed as FEV1%.
