When a patient with SCI performs a push-up pressure relief in a manual wheelchair, how long should they hold the position to ensure adequate tissue reperfusion?

• A. 5-10 seconds
• B. 3-5 minutes
• C. 10-15 minutes
• D. 30 seconds to 1 minute

Answer: (D)

During a push-up pressure relief, the goal is to unload the seating surface and allow blood to return to the tissues that were compressed. Tissue reperfusion needs time for arterial inflow and venous drainage to reset, so holding for about 30 seconds to 1 minute provides an adequate window for the microcirculation to flush and re-oxygenate the skin and underlying tissues. Shorter holds may not allow full reperfusion, while much longer holds aren’t necessary and can put more strain on the shoulders. So, 30 seconds to 1 minute strikes the right balance for effective tissue reperfusion during relief.
