Pulmonary Function - Reference Normal Predicted Values Calculator. Predicted Normal Values Many studies have published lung function reference values for a variety of race/ ethnic groups, countries, and age ranges. Populations of interest are sampled and spriometric studies were done and statistical analyis was used to determine "normal. Knudson's predicted are slightly lower than NHANES and were based on methods with variances from ATS standards (ie FEV1 and FVC are taken from the same best effort rather than largest value from different efforts.) However, Knudson provides predicted values for PEFR - not available in GLI - and important for many allergists.

VOLUME: FVC and FEV1: ±3% of indication or ±50 ml, whichever is greater; MVV: ±10% of indication or ±15 L/min, whichever is greater.

Normal in restrictive disease - reduced in obstructive disease. FEF 25-75%: Forced expiratory flow between 25-75%: Average expiratory flow rate at the middle part of forced expiration. It is a more sensitive indication of what is happening in the middle/lower airways, but is not as reproducible as FEV1. Normal in restrictive disease. PEFR. If you are experiencing respiratory symptoms, you may be wondering, “What is a normal respiratory rate?” Let’s begin by talking about the normal range of respiratory rate for adults and children, how to accurately measure this rate, and what it means if the rate is abnormal.

Prediction equations for the carbon monoxide diffusing capacity of the lung (DLCO) and diffusing capacity per liter of lung volume (DLCO/VA) were derived from 90 normal nonsmoking subjects (40 men and 50 women), using a standardized single-breath technique for Cited by: 2. Predictive Normal Values have been calculated for women and men of different ages and heights, and have been adapted (with agreement from the original Authors) for use with the new EU Scale / EN 23747 peak flow meters.

Aug 04, 2005 · Exercise capacity is an independent predictor of the risk of death and cardiac events among asymptomatic women and men. 1-5 Exercise capacity Cited by: 382. The normal range for vital capacity is 4000-5000 ml, representing about 80% of the total lung capacity. Normal values vary significantly depending on age, sex, and test position. Weight is not a factor in predicting normal values. Various nomograms are available for predicting normal values. Incorrect.
