Purpose: Prolonged ventilation leads to a higher incidence of ventilator-associated pneumonia (VAP), resulting in weaning failure and increased medical costs. The aim of this study was to analyze clinical results and prognostic factors of VAP in patients with blunt chest trauma. Methods: From 2007 t...

인공호흡기 관련 폐렴은 어떻게 발생하는가? | 인공호흡기 관련 폐렴은 기도 내 삽관이나 기관 절개를 통하여 인공호흡기를 장착한지 48시간 이상 경과 후에 발생하는 폐렴을 지칭하며 하부 호흡기와 폐실질 내로 병원균이 침입하여 발생한다. 기도 내 삽관은 기관조직을 손상시켜 미생물이 하부기도와 폐실질 내로 쉽게 침투하여 구강 및 위 내용물이 하부기도로 들어가기 쉬워진다. | |

인공호흡을 받고 있는 환자에게 일어나지 않는 방어기전은? | 정상적인 성인에서는 해부학적 기도 방어장벽, 기침반사, 점액, 점액 섬모 청결작용, 면역기능 등이 관여하여 폐렴이 생기는 것을 방지한다.(5) 그러나 인공호흡을 받고 있는 환자에서는 이러한 방어기전이 방해를 받는다. |
