At the 2008 American Association of Critical-Care Nurses National Teaching Institute, Holtech Medical displayed its new FoleyManometer LV to help monitor intra-abdominal pressure (IAP).
Based on a modified version of the IAP monitoring technique described by Kron et al., the disposable FoleyManometer provides a closed sterile circuit that connects between the patient's Foley catheter and the urine collection device.
Each IAP determination takes about 10 seconds, and no subsequent correction of urine output is required. The urine fills the Foley-Manometer and flows on to the urine collection device. The tube has pressure measurements along its length. When the tube is held upright urine in the vertical manometer tube returns to the bladder when the vent clamp is opened. When holding the 0 mmHg mark of the manometer tube at the pubis level and read at the position of the meniscus. The urine will pulse at the appropriate pressure mark.
