Abstract: A system for facilitating the provision of health care to patients, including computerised means (135) for logging patient data relating to health of the patients, and an administration system (105) in communication with the computerised means and configured to determine a risk status of each patient based on the patient data The administration system is also configured to, for each patient: transmit a first direction to a first health care provider to attend the patient, depending on the risk status of the patient; determine whether the first health care provider has confirmed attendance at the patient within a first time period; and transmit a second direction to a second health care provider to attend the patient within a second time period if attendance by the first health care provider was not confirmed.

Abstract: An improved tonometric catheter can be configured to have one or more pressure transmitting chambers for sensing the internal pressure such as the internal abdominal pressure of a subject. The tonometric catheter is inserted into the patient such as a nasogastric catheter. The pressure sensing chamber in the form of a balloon is insufflated with a pressure transmitting medium when the balloon is in the desired location. After insufflation of the chamber the catheter is connected to a pressure transducer or manometer which then provides an output reading the internal pressure of the subject. The tonometric catheter with a pressure sensing chamber is useful for sensing the internal abdominal pressure such as during laparoscopic surgery. The sensing of internal pressure can also be used at other locations along the gut or in the cranium. The monitoring of internal pressure is also useful in conjunction with the monitoring of internal pH.
