  • How to do
    • Empty the bladder
    • Instill 25mls N saline into the bladder.
    • Place a pressure transducer onto the foley catheter which will measure the pressure in the bladder (the transducer should be zeroed at the level of the patient - iliac crest.
    • Measure the pressure and end expiration.
