For women, the equivalent figure is 85

Normal value of PEF in an adult is approximately 300-350 L/min, i.e. 5-6 L/s (e.g. in 40-year-old man of 170 cm height it is approximately 370±108 L/min resp. 6.2 ±1.8 L/s, in 40-year-old woman Men can have peak flow values as low as 100 liters/minute less than the average value shown and still fall within the normal range. Women can have peak flow values as low as 80 liters/minute less than the average value shown and still fall within the normal range. 2021-04-15 · The 3 peak flow zones are noted by color and include: Green .

Normally the volume exhaled in one second is approximately 80% of the total volume, while the volume after 3 seconds is equal to the FVC PEF = Peak expiratory flow: er det maksimale flow/ hastighed målt ved den maksimale forcerede udånding. Alle disser værdier er med til at danne et billede af hvordan lungernes tilstand er. I forhold til KOL koncentrerer man sig typisk om FVC, FEV1 og FEV1%. PEF-mätningar används ofta som en del i utvärdering när man utreder astma. PEF är ett mått på det maximala utandningsflödet och mäts i L/min.

An LVEF of 65%, for example means that 65% of total amount of blood in the left ventricle is pumped out with each heartbeat.

This is a small, hand-held device utilized to keep an eye on a person’s ability to breathe out air.

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. The definition of normal range is always difficult and may vary between regions and be affected by a variety of factors.

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- ERS & Polgar Spirometry Normal Values.
