During shock resuscitation, a combination of fluids, vasopressors, vasodilators, and inotropes is administered in order to achieve a cardiac output or overall oxygen delivery as per guidelines of individual clinicians. The measurement of ventricular end-diastolic pressure allows a clinician to describe a therapeutic goal of optimum cardiac output response to changes in end-diastolic pressure. This concept has formed the backbone of resuscitative strategies in many forms of shock. ⋯ It is now clear that a significant gradient between pulmonary capillary pressure and PAOP may be present in inflammatory disorders which are not present in noninflammatory states, and that pulmonary capillary pressure may be measured at the bedside of critically ill patients. Bedside measurement of pulmonary capillary pressure may allow for added precision in our therapeutic goals in resuscitation from inflammatory shock. If further studies confirm the reliability and reproducibility of bedside measurement, pulmonary capillary pressure may become an invaluable part of the hemodynamic profile in the critically ill patient in shock.
