Is the Way to Man’s Heart (and Lung) Through the Abdomen?
Intra-abdominal hypertension (IAH) is increasingly recognized to be both prevalent and clinically important in medical and surgical ICUs. Intra-abdominal pressure (IAP) can impact organ function throughout the body, and it can also complicate standard measurements used in ICU care. The article by Krebs et al. reports the effect of IAP on respiratory function, gas exchange and hemodynamic function. Their results show a relatively small effect of modestly elevated IAP on these variables in their patient population. However, their work raises several questions for clinicians and researchers regarding the pathophysiology and management of IAP.
