How should mobilization be approached for a patient on high PEEP or high FiO2?

• A. Proceed cautiously; monitor tolerance; choose low-impact activities; avoid aggressive maneuvers that worsen oxygenation or hemodynamics; adjust PEEP/FiO2 as needed.
• B. Immediately push for maximal exertion regardless of tolerance.
• C. Remove ventilator and mobilize.
• D. Mobilize without considering PEEP/FiO2 levels.

Answer: (A)

Safety and tolerance guide mobilization when a patient is on high PEEP or high FiO2. These settings show significant lung impairment, so the approach must be cautious, with close monitoring and readiness to adjust ventilation as activity progresses. High PEEP and high FiO2 can affect heart and lung dynamics: intrathoracic pressure from PEEP can reduce venous return and cardiac output, while high oxygen needs mean the patient is at risk for desaturation during exertion. Because of this, start with low‑impact activities and advance only as the patient tolerates. Continuously monitor oxygenation (SpO2), vital signs, and symptoms, and adjust PEEP and FiO2 as needed to maintain stable oxygenation during activity. If the patient shows signs of intolerance—desaturation, tachycardia, hypotension, or increased work of breathing—pause the mobilization and reassess. This careful, monitored approach is preferred over pushing for maximal exertion or attempting mobilization without considering ventilator settings or without the ventilator in place, which could compromise oxygen delivery and hemodynamics.
