System for determining electrical status of patient attached leads
First Claim
1. A system for determining electrical status of patient attached leads in medical patient monitoring, comprising:
- a repository of data indicating a plurality of predetermined impedance value ranges and corresponding associated lead status information of at least one electrical lead attached to a patient for conducting electrical signals for use in patient monitoring;
an impedance measurement processor for automatically successively determining whether an impedance value of a particular patient attached lead of a plurality of electrical leads attached to a patient is within a particular impedance value range of a plurality of predetermined impedance value ranges; and
an output processor for automatically communicating data comprising a message identifying an electrical status of a particular lead of said plurality of electrical leads by deriving status information from said repository in response to a determination said impedance value of said particular patient attached lead is within said particular impedance value range.

Abstract
A system determines electrical status of patient attached leads in medical patient monitoring. The system includes a repository of data indicating multiple predetermined impedance value ranges and corresponding associated lead status information of at least one electrical lead attached to a patient for conducting electrical signals for use in patient monitoring. An impedance measurement processor automatically successively determines whether an impedance value of a particular patient attached lead of multiple electrical leads attached to a patient is within a particular impedance value range of multiple predetermined impedance value ranges. An output processor automatically communicates data comprising a message identifying an electrical status of a particular lead of the multiple electrical leads by deriving status information from the repository in response to a determination the impedance value of the particular patient attached lead is within the particular impedance value range.
