What is FEF 25-75 percent?

100


How did changing the radius effect FEV1?

Decreased the FEV1 %


What was the FEV1 at a radius of 5.00 mm?

The FEV1 (%) at a radius of 5 mm is 73.9% (3541/4791 X 100%).


What was the value obtained for the FEV1 divided by FVC x 100 percent with normal breathing?

The normal value for FEV1/FVC ratio with normal breathing is approximately 70-80%. This ratio is used to assess the obstruction of airflow in conditions such as asthma and chronic obstructive pulmonary disease.


What does FEV1 stand for?

Forced expiratory volume


How much of an increase in FEV1 do you think is required for it to be considered significantly improved by the medication?

FEV1 is an index that is used to determine how much restrictive or obstructive lung disease is present in a person's lungs. If the FEV1 level is 70% or less then it is standard practice for medication to be given.


What does fev1 mean?

FEV1 stands for Forced Expiratory Volume in 1 second, which is a measure of lung function. It indicates the amount of air a person can forcefully exhale in one second after taking a deep breath. FEV1 is commonly used in assessing respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD).


What are the factors that affect FEV1?

Factors that can affect FEV1 (forced expiratory volume in one second) include age, gender, lung size, airway obstruction, smoking, and certain medical conditions such as asthma or chronic obstructive pulmonary disease (COPD). Regular physical activity and maintaining a healthy lifestyle can also influence FEV1.


How accurate are different types of flow meters in measuring FEV1?

Generally, most flow meters are very accurate in FEV1. However, device accuracy is not especially important, rather it is essential that you take multiple measurements to calculate an accurate working average.


Why is FEV1 low in asthmatics?

In asthmatics, the airways become narrowed due to inflammation and constriction of the smooth muscles around the airways. This leads to difficulty in exhaling air from the lungs, resulting in a lower FEV1 (forced expiratory volume in 1 second) value. Additionally, increased mucus production in the airways can further contribute to decreased airflow and lower FEV1 measurements in asthmatics.


What is expected lifetime of someone who is 71 with mild emphysema?

The prognosis will depend on the individual's health and lifestyle. Minor emphysema has an FEV1 rate of over 80 percent survival.
