  • Objective To investigate and demonstrate persistent increase of peak cough flow after mechanical in-exsufflator application, in patients with neuromuscular diseases and pneumonia. Methods A mechanical in-exsufflator was applied with patients in an upright or semi-upright sitting position (pressure setting, +40 and $-40cmH_2O$; in-exsufflation times, 2-3 and 1-2 seconds, respectively). Patients underwent five cycles, with 20-30 second intervals to prevent hyperventilation. Peak cough flow without and with assistive maneuvers, was evaluated before, and 15 and 45 minutes after mechanical in-exsufflator application. Results Peak cough flow was 92.6 L/min at baseline, and 100.4 and 100.7 L/min at 15 and 45 minutes after mechanical in-exsufflator application, respectively. Assisted peak cough flow at baseline, 15 minutes, and 45 minutes after mechanical in-exsufflator application was 170.7, 179.3, and 184.1 L/min, respectively. While peak cough flow and assisted peak cough flow increased significantly at 15 minutes after mechanical in-exsufflator application compared with baseline (p=0.030 and p=0.016), no statistical difference was observed between 15 and 45 minutes. Conclusion Increased peak cough flow after mechanical in-exsufflator application persists for at least 45 minutes.

  • 본 연구는 강제 양압식 호흡훈련이 기관절개관을 삽입한 뇌졸중 환자의 호흡능력 및 기침능력에 미치는 효과에 대하여 알아보고자 실시하였다. 연구대상은 기관절개관을 삽입한 뇌졸중 환자 10명으로 하였으며, 대상자는 강제 양압식 호흡훈련을 20분씩 주 5회 8주간 실시하였다. 훈련 전, 훈련 4주 후 그리고 8주 후 대상자의 노력성 폐활량, 1초간 노력성 호기량, 노력성 폐활량비 그리고 도수 보조 최대 기침유량을 측정하였으며 기간에 따른 호흡능력과 기침능력을 알아보고자 반복측정 분산분석법을 이용하였다. 연구 결과 훈련기간에 따라 대상자의 노력성 폐활량, 1초간 노력성 호기량, 도수 보조 최대 기침유량은 유의하게 증가하였다. 따라서 강제 양압식 호흡훈련은 기관절개관을 삽입한 뇌졸중 환자의 호흡능력 및 기침능력을 증진시켜 기관절개관을 제거하는데 유용한 훈련방법이라 할 수 있다.
