Spiegelberg IAP catheters continuously measure the intraabdominal pressure via the air pouch at the tip of the catheter and they are compatible with all Spiegelberg ICP monitors.
Spiegelberg IAP catheters can be used immediately, because they do not require calibration before use. The IAP catheter is inserted like a nasogastric tube. There is an air pouch at the tip. The catheter has two lumens: one lumen for connection of the air pouch to the Spiegelberg ICP monitor and one lumen for insertion of the guide wire.
