Which ventilator considerations guide mobilization in a patient on mechanical ventilation?

• A. Assess readiness for spontaneous breathing trial
• B. Ensure acceptable FiO2/PEEP
• C. Monitor airway pressures
• D. Assess readiness for spontaneous breathing trial, ensure acceptable FiO2/PEEP, monitor airway pressures, and verify tolerability of activity with the mode

Answer: (D)

Mobilization on the ventilator is safe only when the respiratory system can tolerate activity without compromising gas exchange or causing instability. Start by assessing readiness for a spontaneous breathing trial, because if the patient can tolerate reduced support, they’re more likely to handle movement without distress or weaning failure during activity. Next, ensure oxygenation and ventilator settings are acceptable—FiO2 kept at a level that supports adequate oxygenation and a PEEP that maintains lung recruitment without overdistension during activity. Then, monitor airway pressures throughout the movement; rising peak or plateau pressures or high driving pressures suggest poor lung mechanics or a risk of barotrauma during exertion, signaling a need to pause or adjust. Finally, verify tolerability of activity with the current mode by watching for signs of distress, desaturation, hemodynamic instability, or poor ventilator synchrony. If all these are acceptable, mobilization can proceed; if any are unfavorable, reassess and modify plan accordingly.
