A patient receiving PEEP therapy is displaying signs of hemodynamic instability. What should be the first intervention?

• A. Reduce PEEP levels
• B. Increase tidal volumes
• C. Change to AC mode
• D. Monitor cardiovascular parameters

Answer: (A)

Reducing PEEP levels is a critical first intervention for a patient exhibiting hemodynamic instability while receiving PEEP therapy. PEEP (Positive End-Expiratory Pressure) increases intrathoracic pressure, which can impair venous return to the heart, potentially leading to decreased cardiac output and worsening hemodynamic status. By lowering PEEP, you can alleviate this pressure and improve venous return, thus helping to stabilize the patient's hemodynamics. This approach is particularly important in patients who may already have compromised cardiovascular function or reduced preload. Reducing PEEP can lead to better cardiac filling and improved overall stability. In contrast, increasing tidal volumes may further increase intrathoracic pressure and compromise hemodynamics, changing to AC (Assist-Control) mode does not directly address the immediate issue of hemodynamic instability, and monitoring cardiovascular parameters, while essential, does not provide an immediate corrective action to address the instability observed.
