What is the difference between the FEV1 and peak expiratory flow?
FEV1 is the peak during the first second of exhalation only.
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.
PRIYA WHAT does it mean?
it mean a person to be beloved
What does penatude mean?
Penatude does not mean anything.
What does telegraphed his motion mean?
what does he telegraphed his motion mean
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 is the difference between the FEV1 and peak expiratory flow?
FEV1 is the peak during the first second of exhalation only.
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.
FVC and FEV1 measure what function?
Forced vital capacity (FVC) measures the total volume of air exhaled forcefully after a maximal inhalation. Within this total volume exhaled, the forced expiratory volume (FEV1) is measured during the 1st second of this manoeuvre.
What is FEF 25-75 percent?
100
What is a routine pulmonary functions test?
measurement of lung function through spirometry yielding values including FEV1, FVC, FEV1/FVC ration PEF and FEF 25-75: 50, 75 aned soemtimes 85 % of predicted value
What do you think is the clinical importance of the FVC and FEV1 values?
FVC measures the amount of gases expelled when a subject takes a deep breath & then forcefully exhales maximally and as rapidly as possible. FEV1 determines the amount of air expelled during the first second.
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.
When surfactant is added what happens to the tidal volume?
FEV1 percentage decreases as the radius of the airway is decreased.
What was the value obtained for the FEV1 divided by FVC x 100 percent with normal breathing?
80%
