Critically ill patients are transported within and between hospitals on a regular basis; thus, transport of the critically ill is a component of most intensivists-practice. The motivation for these transports lies in obtaining diagnostic or therapeutic services not available at the bedside (intrahospital transport) or not available in the sending institution (interhospital transport). Deterioration in respiratory, cardiovascular, and other physiological systems is a potential complication of any patient transport. Using appropriate equipment and personnel and planning for each transport can minimize these complications and ensure optimal benefit to the patient.
