Abstract

<p> 深呼吸訓練の換気機能・呼吸筋力・呼吸抵抗に及ぼす効果について明らかにし,術後無気肺予防への有効性を検証した.18歳から22歳の健康女子を対象に,深呼吸訓練を行わない対照群(13名),深呼吸訓練を行う実験群(15名)の2群に分け,実験群は深呼吸を1セットにつき10回,1日4セットを10日間行った.両群ともに実験開始前と10日目に換気機能・呼吸筋力・呼吸抵抗を測定した.<br> 実験群のVC(Vital Capacity),FVC(Forced Vital Capacity)の有意な増加から,深呼吸訓練には呼吸訓練器具を用いた訓練と同等の効果があると認められた.また,VC・FVCの増加に加えて実験群のMEP(Maximal Expiratory Pressure)が有意に増加したことから,深呼吸訓練による自己排痰能力の向上が示唆された.呼吸抵抗については,全ての測定項目に有意な変化がなかったことから深呼吸訓練によるVCやFVCの増加は,肺組織(肺胞)の拡張によるものと推察された.</p>

<p>This study examined the effectiveness of deep breathing practice to prevent postoperative atelectasis by clarifying its effects on ventilation and the respiratory muscle strength/resistance. Twenty-eight healthy females aged 18 to 22 were divided into 2 groups with (experimental: 15) and without (control: 13) deep breathing practice. The former performed 4 sets of deep breathing daily, each of which consisted of 10 repetitions, for 10 days. In both groups, ventilation, the respiratory muscle strength, and respiratory resistance were measured before and 10 days after the initiation of the experiment. <br>The vital (VC) and forced vital (FVC) capacities significantly increased in the experimental group, revealing similar effects of deep breathing practice to those of breathing training using devices. Furthermore, in this group, the maximal expiratory pressure (MEP) markedly increased with the rises in the VC and FVC, suggesting that such practice also improves the ability to expectorate. As for respiratory resistance, there were no significant changes in the all measurement items. Based on this, deep breathing practice may have increased the VC and FVC by expanding the lung tissues (alveoli) . </p>
