FEV1 stands for forced expiratory volume in 1 second.

This is called the forced expiratory volume, or FEV1.

FEV1 (forced expiratory volume in 1 second) should be above 80% of predicted values to be considered normal.

We measured the patients' arterial blood gas tensions, forced expiratory volume, and forced vital capacity.

A home spirometer allows you to measure your forced expiratory volume at 1 second (FEV1).

This results in a more specific measure known as FEV subscript1, or forced expiratory volume in one second.

That speed is referred to as FEV1 - or Forced Expiratory Volume in 1 second.

Economically valuable health Some health effects, such as forced expiratory volume and other technical measurements of effects lung function, are difficult to value in monetary terms.

Robuschi et al showed that aerosol challenge of asthmatic patients with acetaldehyde caused a consistent reduction in forced expiratory volume in one second.

Forced expiratory volume (FEV).

Exhaled volumes are measured by a pulmonary function test or simple spirometry, leading to an elevated residual volume and a measurement of forced expiratory volume.

It is clinically classified according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate.

Forced expiratory volume in 1 second (FEV1), the amount of air breathed out as forcefully as possible in 1 second.

Traditional treatments such as physiotherapy and an inhaler didn't help, so he began taking measurements with a device called a peak flow and forced expiratory volume monitor.

A spirometry test can measure: Forced expiratory volume (FEV), which is the amount of air you can exhale with force in one breath.

The volume in a one-second forced exhalation is called the forced expiratory volume in one second (FEV1), measured in liters.

A non-specific bronchial hyperreactivity test involves testing with methacoline, after which the Forced Expiratory Volume in 1 second (FEV) of the patient is measured.

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).

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.

COPD is defined as a forced expiratory volume in 1 second to forced vital capacity ratio (FEV1/FVC) that is less than 0.7.

The effect of a provocative dose of histamine on forced expiratory volume (PC 2 ) was assessed in the clinic; the patient also completed the Spielberger test to measure dispositional anxiety.

Change in forced expiratory volume in one second (FEV 1 ), heart rate, plasma potassium concentration, QTc interval, tremor amplitude, and creatine kinase myocardial isoenzyme concentration.

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) by at least 20%.

The guidelines indicating transplantation include progression despite medical treatment, forced expiratory volume in 1 second (FEV1)/forced vital capacity ratio of less than 50%, total lung capacity of greater than 130%, and FEV1 of less than 30%.

In the second Phase III trial, TIGER-2, the compound did not meet the primary endpoint, a significant change in baseline FEV1 (forced expiratory volume in one second) at the week 48 endpoint as compared to placebo.
