A method and apparatus for determining cardiac parameters within the body of a patient includes a wireless sensor positioned in the patient's pulmonary artery. An external RF telemetry device communicates wirelessly with the sensor and interrogates the sensor to determine changes in pressure in the pulmonary artery over time. The peak pressure difference is determined. Then, assuming zero blood flow velocity at the time of valve opening and at the time of valve closing, a velocity-time function is determined. The velocity-time function is used to determine a velocity-time integral. The velocity-time integral is then used to determine cardiac stroke volume. The cardiac stroke volume is multiplied times the heartbeat rate to determine cardiac output. The cardiac output can be monitored over time to determine continuous cardiac output.

The present invention relates to a failure detection method and system operating at the session control layer, preferably within an IMS/SIP architecture, which monitors the status of an adjacent node with the aid of a timer mechanism that sets a heartbeat rate associated with that adjacent node. Monitoring of a communication session takes place by monitoring the liveliness of the nodes handling the session.

According to some embodiments, SIP traffic within an on-going communication session is used to determine whether an adjacent node is alive. Failure to receive a SIP message from an adjacent node within a given heartbeat rate starts a polling process to decide whether the adjacent node is in a faulty status. In the affirmative, i.e. upon decision that the adjacent node is in a faulty status, the polling node closes the communication session so that any further billing is prevented.

According to some other embodiments, when a transport connection has been established between two adjacent SIP nodes, the node that has initiated the connection starts a polling process for monitoring the liveliness of the adjacent node. The polling process comprises the step of sending a first polling message requesting the adjacent node to initialise a timer with a heartbeat rate proposed by the initiating node or agreed between the two nodes. Initialisation of the timer triggers in the adjacent node the response to the polling message. Failure to receive an acknowledgement message from an adjacent node within a given heartbeat rate determines one or more actions in the initiating node aimed at the decision of a faulty status of the adjacent node. Upon decision that the adjacent node is in a faulty status, the initiating node closes the communication session so that any further billing is prevented.
