If a patient desaturates during mobilization, what is the typical clinical response?

• A. Ignore and continue.
• B. Discontinue mobilization entirely.
• C. Pause mobilization, reassess, and adjust plan.
• D. Discharge patient.

Answer: (C)

Safety during mobilization hinges on recognizing when the activity exceeds the patient’s current ability to oxygenate and ventilate. When desaturation happens, the first move is to pause the activity and reassess what’s going on. Check the oxygen delivery and ensure the patient is receiving what they need (adjust FiO2 or oxygen delivery as appropriate), and look at the vital signs and symptoms— heart rate, blood pressure, work of breathing, level of distress, and pain. Reassess the airway and secretions, and consider factors like positioning, sedation, anemia, fluid status, or recent changes in respiratory status.

With a clearer picture, decide how to proceed: you may resume at a lower intensity or with longer rest periods, modify the position or technique, or choose to stop the session and plan for a later progression once the patient is better tolerated. Throughout, aim to keep oxygenation within a safe range (and document the response). If desaturation persists or there are signs of instability, escalate per protocol and involve the team. The key idea is matching activity to the patient’s current respiratory and cardiovascular reserve and stopping or adapting when safety thresholds are approached.
