Delayed vasopressor delivery

Educational use only. Not clinically reviewed

58-year-old woman for Vasopressor infusion-path and startup review. About 8 simulated minutes.

What you will practise

Recognize that a running pump command does not prove vasopressor delivery to the patient.
Trace the declared syringe, pump, tubing, connections, downstream volume, carrier, catheter, and patient.
Classify the fixed pattern as delayed delivery from dead-space and startup mechanics while keeping other causes open.
Activate nursing, pharmacy, and local safe-start or changeover protocol without flushing concentrated drug into the patient.
Reassess delivery evidence, pressure, perfusion, and the ongoing shock plan.
