A Study on The Deaf Student’s Cardiorespiratory Fuction

&nbsp;&nbsp;The purpose of this study was to investigate and compare pulmonary ventilation, cardiorespiratory fuction of deaf person and normal person.<BR>&nbsp;&nbsp;For this purpose, 26 subjects(13 deaf person, 13 normal person) were selected.<BR>&nbsp;&nbsp;The results were as followings.<BR>&nbsp;&nbsp;1. Pulmonary ventilation<BR>&nbsp;&nbsp;1) The slow vital capacity showed great significant difference(p＜.05) and the predominant order of the mean value of slow vital capacity was deaf person(4.13±0.70 l), normal person(4.71±0.38 l).<BR>&nbsp;&nbsp;2) The forced vital capacity showed great significant difference(p＜.001) and the predominant order of the mean value of forced vital capacity was deaf person(3.84±0.67 l), normal person(4.54±0.47 l).<BR>&nbsp;&nbsp;3) The forced expiratory volume in I second showed great significant difference(p＜.001) and the predominant order of the mean value of forced expiratory volume in I second was deaf person(3.56±0.34 l), normal person(4.10±0.41 l).<BR>&nbsp;&nbsp;4) The forced expiratory flow 200-1200ml showed great significant difference(p＜.001) and the predominant order of the mean value of forced expiratory flow 200-1200ml was deaf person(7.35±1.32 l), normal person(9.20±1.25 l).<BR>&nbsp;&nbsp;5) The maximal voluntary ventilation showed great significant difference(p＜.05) and the predominant order of the mean value of maximal voluntary ventilation was deaf person(119.85±24.98 l), normal person(152.43±30.39 l).<BR>&nbsp;&nbsp;6) The precent forced expiratory volume in I second, forced expiratory flow 25-75%, peak expiratory flow, slow vital capacity showed no significance.<BR>&nbsp;&nbsp;2. Cardiorespiratory function<BR>&nbsp;&nbsp;1) The ventilation in time of maximum exercise showed great significant difference(p＜.05) and the predominant order of the mean value of the ventilation in time of maximum exercise was the deaf person(103.88±18.45 l/min), normal person(122.51±20.18 l/min).<BR>&nbsp;&nbsp;2) The heart rate in time of maximum exercise showed great significant difference(p＜.05) and the predominant order of the mean value of the heart rate in time of maximum exercise was deaf person(198.38±5.47heats/min), normal person(203.42±6.66heats/min).<BR>&nbsp;&nbsp;3) The ventilation in time of rest, heart rate in time of maximum exercise, oxygen pulse in time of maximum exercise and rest, oxygen consumption in time of maximum exercise and rest, carbon dioxide production in time of maximum exercise and rest, oxygen consumption per ㎏ body weight in time of maximum exercise and rest, tidal volume in time of maximum exercise and rest, respiratory rate in time of maximum exercise and rest, showed no significance.
