Abstract
Central venous pressure (CVP) is the pressure within the superior vena cava and its montioring helps to assess cardiac function. Application of positive pressure ventilation may be a factor that affects CVP values. Aim: The aim of this study is to investigate the relationship between CVP values and positive pressure mechanical ventilation among cardiac versus non-cardiac patients in the intensive care units at Cairo University Hospitals. Design: Descriptive correlational comparative research design was utilized in the current study. Sample: 82 adult mechanically ventilated patients on positive airway pressure ventilation with steady circulatory state. Divided into two equal groups; Cardiac and Non-cardiac groups.
