1. A pneumocardial function monitor comprising:
- a carrier configured to be mounted about a thorax of a subject;
a sensor mounted on the carrier, the sensor configured to monitor changes in volume of the thorax of the subject, the sensor comprising a plurality of sensing elements, which operate together to monitor at least respiratory function, which comprises measurement of changes in chest volume and measurement of diaphragm activation of the subject, which are used to interpret respiratory effort, wherein at least one of the sensing elements measures cardiac events based on volume changes of the thorax; and
a signal processor in communication with the sensor configured to process signals output from the sensor, the signal processor having at least two outputs, a first output configured to transmit a first signal related to volume changes of the thorax, the first signal being related to respiratory function, and a second output configured to transmit a second signal from which volume changes of the thorax related to respiratory function have been filtered out, the second signal being related to cardiac function.

Abstract
A pneumocardial function monitor includes a carrier configured to be mounted about at least a part of a trunk of a body of a subject. A sensing arrangement is mounted on the carrier, the sensing arrangement including at least one element for monitoring changes in volume of the part of the subject'"'"'s body. A signal processing module is in communication with the sensing arrangement for processing signals output from the sensing arrangement, the signal processing module having at least one output for outputting a signal related to respiratory function and/or cardiac function.

14. A method of monitoring pneumocardial function, the method comprising:
-
mounting a carrier about a thorax of a subject, the carrier mounting a sensor configured to monitor changes in volume of the thorax of the subject, the sensor comprising a plurality of sensing elements; using the plurality of sensing elements to measure respiratory function which comprises measurement of changes in chest volume and measurement of diaphragm activation of the subject which are used to interpret respiratory effort, wherein at least one of the sensing elements further measures cardiac events based on volume changes of the thorax; processing data output by the sensor; and outputting a first signal relating volume changes of the thorax related to respiratory function and outputting a second signal from which volume changes of the thorax related to respiratory function have been filtered out, the second signal being related to cardiac function. - View Dependent Claims (15, 16)
