Abstract |
1. A comparative analysis of TVC 1.0. MMF and MEFR were made among total 86 R.O.K. Navy serviceman and Factory workers.
2. The normal range of each parameter are outlined as TVC 1.0: 70.3- 88.2 %. MMF: 2.01-5.59 L/sec. and MEFR: 138.67- 631.30 L/min. respectively, and these are quite similar 10 those reported by ‘other workers except in MEFR value which is measured by P.E. Lansing's simplified method.
3. For comparison of the variability o{ these three parameter, the Coetticient of variation are obtained by dividing the standard deviation by the mean of each parameter. And it is suggested that the TVC 1.0 is most narrow range of normal value.
4. Some regression of each values was observed with advancing age. |
