Sterile saline is hung on an intravenous pole. [17] The saline bag tubing spike is placed into the saline bag. A pressure cuff is around the saline bag is unnecessary.

The AbViser is primed by aspirating and compressing the syringe to flush all of the air from the infusing tubing until saline runs out of the AbViser autovalve and all of the bubbles are out of the tubing. The end of the urine catheter is aseptically prepared and then placed over the barbed connector of the AbViser. The drain tubing is connected to the AbViser valve.

The catheter connection is ensured, the area dried, and a strip of tape wrapped around the end of the catheter to keep the connection snug.

The pressure transducer is attached to the patient or to an intravenous pole at the level of the iliac crest in the midaxillary line. After zeroing the transducer, ensure that stopcock is open to the patient and the transducer.

To measure the bladder pressure, the patient must be supine. The plunger is retracted until 20 mL (in adults) of fluid is within the syringe. The syringe plunger is compressed within 10 seconds, infusing the fluid into the bladder.

To record IAP, allow the system to equilibrate and then note the pressure reading on the monitor at the end of expiration. The IAP reading lasts for 1-3 minutes, and the valve will then automatically open and the pressure reading will decrease to zero.

After the pressure is recorded, one should confirm that the autovalve has opened and urine is draining normally. The valve will remain open until the next volume of fluid is infused.
