Patient monitoring systems and methods
First Claim
1. A system for monitoring patient physiological data, comprising:
- a pad having a plurality of electrical contacts formed thereon in a predetermined pattern, the electrical contacts being configured to sense electrical signals produced by a patient'"'"'s body;
a controller in communication with the electrical contacts and configured to select at least two electrical contacts, each sensing a processable electrical signal, and to process a differential signal derived from the processable signals; and
an output device in communication with the controller for displaying the patient'"'"'s physiological data based on information processed by the controller;
wherein the controller is further configured to actively change the selection of the at least two electrical contacts over time by periodically determining which of the plurality of electrical contacts are in contact with the patient and changing the selection of the at least two electrical contacts based on an assessment of the quality of the sensed electrical signals.

Abstract
Various systems and methods are provided for monitoring patient physiological data without the need for adhesives or wires to be connected to a patient. The system is also fully functional without the need for manipulation or intervention by a care provider or medical personnel. In particular, the system can include a pad having a plurality of electrical contacts or electrodes formed thereon in a predetermined pattern. The electrodes can be configured to sense electrical signals produced by a patient'"'"'s body. A controller in communication with the electrodes can be configured to select and process signals from the electrodes and send the information derived from the electrical signals to an output device for displaying resulting physiological data so that the patient can be monitored.

13. A system for monitoring patient physiological data, comprising:
-
a pad having an array of electrodes formed thereon in a predetermined configuration, the pad being configured to be positioned adjacent to a patient'"'"'s skin; and a processor in communication with the pad and configured to select at least two electrodes from the array of electrodes, to process electrical signals received from the at least two electrodes, and to generate physiological data derived from the electrical signals; wherein the processor is further configured to actively change the selection of the at least two electrodes over time by periodically determining which of the electrodes from the array of electrodes are in contact with the patient and changing the selection of the at least two electrodes based on an assessment of the quality of the received electrical signals. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
