The gravitational distribution of ventilation-perfusion ratio is more uniform in prone than supine posture in the normal human lung
AC Henderson, RC Sá, RJ Theilmann… - Journal of applied …, 2013 - journals.physiology.org
The gravitational gradient of intrapleural pressure is suggested to be less in prone posture
than supine. Thus the gravitational distribution of ventilation is expected to be more uniform …
