Patient temperature response control system and method
First Claim
1. A system for use in a patient cooling therapy procedure, comprising:
- a monitoring device for monitoring patient shivering and for providing a monitoring signal responsive thereto, wherein the monitoring device includes a motion sensor and is selectively interconnectable in fixed relation to and disconnectable from a patient;
a control unit configurable to cool and warm a circulated fluid through at least one contact pad for thermal exchange with the patient, including;
at least one processor programmed to;
control automatically a temperature of the circulated fluid so as to cool and warm the patient in different treatment phases in accordance with a predetermined protocol; and
,process said monitoring signal to provide an output signal indicative of a magnitude of patient shivering; and
,a user interface to graphically display, on an ongoing basis as a function of time during the patient cooling therapy procedure, each of the following;
patient motion data, responsive to said output signal, indicating the magnitude of patient shivering as a function of time, wherein said patient motion data is displayed in relation to a predetermined magnitude scale having a plurality of predetermined levels of patient motion indicative of increasing degrees of patient shivering a predetermined patient temperature adjustment rate plot indicating a desired patient temperature to be reached as a function of time;
a measured patient temperature plot indicating a measured patient temperature as a function of time; and
,a measured circulated fluid temperature plot indicating a measured temperature of said circulated fluid as a function of time.

Abstract
A system and method are provided that employ a monitoring device to monitor at least one patient physiological response to a change in temperature of the patient (e.g. pursuant to induced hypothermia therapy), wherein a monitoring signal is provided by the monitoring device. In turn, an output (e.g. a visual and/or auditory output) may be provided to a user indicative of at least one measure of patient response to the change in temperature. Alternatively or additionally, a processor may be provided to process the monitoring signal and provide an output employable by medical personnel to control a patient shivering response to the patient temperature change. Such information may comprise information regarding one or more anti-shivering medicament(s), e.g. corresponding dosage and/or frequency information for use by medical personnel in the administration of the anti-shivering medicament. In one approach, a motion sensor may be selectively attached to a patient'"'"'s chin to provide a wireless monitoring signal to a transceiver. In turn, the transceiver may provide the monitoring signal to the processor on an ongoing basis to output information useful in the administration of an anti-shivering medicament, including updated information that takes into account a patient'"'"'s response to a prior administration of one or more medicaments in conjunction with the subsequent administration of an anti-shivering medicament.
