Peak flow measurement is a quick test to measure air flowing out of the lungs. The measurement is also called the peak expiratory flow rate (PEFR) or the peak expiratory flow (PEF). Peak flow measurement is mostly done by people who have asthma. Peak flow measurement can show the amount and rate of air that can be forcefully breathed out of the

Normal Spirometry . A normal flow-volume loop: A normal Flow-Volume loop begins on the X-axis (Volume axis): at the start of the test both flow and volume are equal to zero. After the starting point the curve rapidly mounts to a peak: Peak (Expiratory) Flow. After the PEF the curve descends (=the flow decreases) as more air is expired.

Normal Heart. A normal left ventricular ejection fraction (LVEF) ranges from 55% to 70%. An LVEF of 65%, for example means that 65% of total amount of blood in the left ventricle is pumped out with each heartbeat.

Your EF can go up and down, based on your heart condition and how well your treatment works. HF-pEF. 1999-05-01 Objective: International consensus guidelines suggest that in asthma and chronic obstructive pulmonary disease (COPD), measurements of FEV1 and PEF are equivalent in the assessment of the degree of airflow obstruction when expressed as the per cent of predicted values. Methodology: In this retrospective study, 2,587 paired measurements of PEF and FEV1 performed by 101 adult patients … Daily monitoring of peak expiratory flow (PEF) or forced expiratory volume in 1 second (FEV1) should not be performed routinely to monitor recovery from an exacerbation because the magnitude of changes is small compared with the variability of the measurement.

Reduction in PEF is usually indicative of onset of asthma symptoms. However, use can be made of PEF values only if normal values are known.

Low FEV1/FVC with normal FEV1 Sometimes the ratio of FEV1 to FVC is below the lower limit of normal (-1.645 SR), with the FEV1 being in the normal range but the subject's FVC being much greater than predicted. There is some uncertainty about the clinical picture here, but a subject can be born with supra-normal lung func-
