    Pulmonary artery (PA) catheterization is useful for severe shock, ARDS, and heart failure, but less so for less critical conditions. Careful consideration of PA catheter benefits versus risks is essential for patient care.

    Area of Science:

    • Critical Care Medicine
    • Cardiovascular Physiology
    • Medical Device Efficacy

    Background:

    • Pulmonary artery (PA) catheterization is widely used in critically ill patients.
    • Increased clinical experience has led to more indications and complications.
    • The appropriateness and benefits of PA catheterization are under scrutiny.

    Purpose of the Study:

    • To review the indications for PA catheterization.
    • To assess the relevance of PA catheter use in patient care.
    • To evaluate the diagnostic utility and limitations of PA catheter data.

    Main Methods:

    • Review of clinical literature and practice guidelines.
    • Analysis of PA catheter indications and associated complications.
    • Evaluation of cost-benefit aspects in different patient subsets.

    Main Results:

    • PA catheterization is beneficial in severe shock, ARDS, and refractory cardiac failure.
    • Hemodynamic assessment is valuable for patients on high-dose vasoactive agents.
    • Patients with minimal disease or correctable hypovolemia, COPD, or on dialysis rarely require PA catheterization.
    • Technical, septic, and thromboembolic complications are significant concerns.

    Conclusions:

    • PA catheter use should be judicious, reserved for specific critical conditions.
    • Diagnostic information must be interpreted in clinical context, acknowledging data limitations.
    • Cost-benefit analysis is crucial for optimizing PA catheter utilization.
