Prediction Equations for Spirometry in Indian Population of Elderly Two (Male & Female) Group

To establish numerical norms of cardio-respiratory functions and collect substantial amount of data relating to physical fitness in elderly peoples. The spirometer consists of a vessel placed inverted like a bell in jacket of water. A wide air passage through the Centre of the jacket communicates with the bell. The other end of the passage is connected through a corrugated impervious tubing to a mouth piece; when the subject breaths out through it, the expired air lifts the bell. A counter weight attached to a wire over a pully, balances the weight of the bell, and a pointer records the volume contained in the spirometer. The scale is marked on a wheel fixed over the pully.

The present study “The Cardiorespiratory Function Tests” was conducted on a randomly selected 110 apparently healthy subjects of 60 years and above age group belonging to both the sexes at Agra. The survey was conducted under the joint auspices of Department of Physiology and Department of Cardiology, S.N. Medical College, Agra.

In elderly man (60+) mean the average vital capacity (V.C) was 2334.3 ± 370.3 ml and in elderly women (60+) 2206.2 ± 297.5 ml.

The prediction equations have been developed for spirometry variables in elderly group of Indian origin using the current ATS/ERS spirometry standardisation recommendations. The equations suggest an improvement in the lung health of the population over time in the middle-aged and the elderly. These equations should address a long-felt unmet need and enable a more appropriate evaluation of spirometry data in different chest diseases in Indian subjects. It can be applied clinically for improving balance in elderly population.
