1. A method of determining the intra-abdominal pressure in a patient having a catheter that drains fluid from the patient into a collection container, the method comprising the steps of:

  • positioning a reservoir between the catheter and the collection container, the reservoir being connected to the catheter by a transparent inlet tube such that the reservoir fills with the fluid drained from the patient when the reservoir is positioned below the patient;

    raising the reservoir to a defined measurement height above the patient such that the volume of the fluid in the reservoir flows back into the patient through the transparent inlet tube and the catheter; and

    measuring the height of the fluid in the transparent inlet tube after the fluid has been returned to the patient from the reservoir to determine the intraabdominal pressure in the patient.
