title: Influence of mechanical ventilation and pulmonary disease on pulmonary artery pressure monitoring.
abstract: Mechanical ventilation and respiratory disease impose both theoretical and practical limitations on the interpretation of hemodynamic measurements. To properly interpret such information a thorough understanding of the circulatory changes associated with normal breathing, mechanical ventilation and respiratory disease is vital. There are a variety of factors involved in patients with obstructive lung disease and those receiving mechanical ventilation that complicate the usual interpretation of hemodynamic data obtained from flow-directed catheters. An awareness of the potential pitfalls of hemodynamic monitoring in such situations is important in the efficient use of the hemodynamic data obtained.
