Forced Expiratory Volume (FEV1) – is the volume amount of air exhaled during the first second of a forced lung exhalation test.

Forced Expiratory Volume in One Second/Vital Capacity

Forced Expiratory Volume In One Second/Forced Vital Capacity

Forced expiratory volume in one second /forced vital capacity

Thereafter, the device prompts the patient to exhale the forced vital capacity of the lungs.

SMART ONE can write to "Health" the following data (Peak Expiratory Flow Rate, Forced Expiratory Volume 1sec, Height, Weight)

It is a lung monitoring device and is used to measure peak expiratory flow rate and forced expiratory volume.

A data acquisition processor acquires patient medical data related to inspiratory and expiratory volume from a ventilator.

Forced expiratory volume in one second is abbreviated to FEV.

SMART ONE can read from "Health" the following data (Date of Birth, Sex, Height, Weight, Peak Expiratory Flow Rate, Forced Expiratory Volume 1sec).

The most common spirometry measurements are peak expiratory flow (PEF), forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC).

Forced expiratory volume is less than 30 percent of normal value.

Forced expiratory volume (FEV-1) – the maximum amount of air exhaled in one second

FVC: forced vital capacity; FEV1: forced expiratory volume in one second; FEF25-75: forced expiratory flow between 25% and 75% of forced vital capacity.

Forced expiratory volume is equal to or greater than 80 percent of normal value.
