To review the literature addressing the use of the pulmonary artery catheter (PAC) in patients with respiratory failure. ⋯ The optimal role of the PAC as a diagnostic and monitoring device in different types of respiratory failure has not been clearly defined. Research is needed to determine the role of the PAC in very carefully defined groups of patients with respiratory failure.
-
To review the literature addressing use of the pulmonary artery catheter (PAC) to augment oxygen delivery to supranormal levels in critical illness. ⋯ Further research must be performed before a recommendation can be made about goal-oriented hemodynamic intervention utilizing the PAC to augment oxygen delivery to supranormal levels prior to high-risk surgery. PAC-guided hemodynamic intervention to augment oxygen delivery to supranormal values in patients with SIRS-related organ dysfunction from sepsis, trauma, or postoperative complications is not recommended at this time. Carefully designed, multicenter, randomized, controlled trials are needed to establish whether augmenting oxygen delivery improves organ-specific outcomes and survival under each of these circumstances.

To review the literature addressing use of the pulmonary artery catheter (PAC) in patients with sepsis and septic shock. ⋯ Based largely upon expert opinion, PAC use may be appropriate in patients with septic shock unresponsive to early resuscitative measures. Maintenance of normal hemodynamics in this group of patients appears to be the appropriate goal. Research is needed to determine the proper role of the PAC in patients with sepsis/septic shock.
-
To review the literature addressing the new pulmonary artery catheters: continuous venous oximetry, right ventricular ejection fraction, and continuous cardiac output. ⋯ Clinician misinterpretation and misapplication of the data appear to be the greatest impediment to using pulmonary artery catheterization to alter pathophysiologic processes and improve outcome in critically ill patients. Future research should first document effectiveness or lack of effectiveness of the "standard" pulmonary artery catheter (PAC). Pending these results, outcome and cost/benefit studies should be performed comparing "standard" with new PACs.
