Abstract

Some embodiments of the invention provide a system to monitor a patient. In some aspects, a signal representing a value of a physiological parameter is received from a monitoring device. The received value is a value that caused the monitoring device to trigger an alarm associated with the psychological parameter. A notification is determined based on the received signal and on a second signal that represents a value of a second physiological parameter. The notification is then presented to an operator.

Claims

1. A medical alarm system for processing information from a plurality of patient monitoring devices adapted to be attached to a patient and having at least one physiological sensor that produces a signal representing at least one patient physiological parameter and transmit the signal via a communications network, the system comprising:

a communication interface configured to receive a signal representing patient physiological parameter values from the plurality of patient monitoring devices for a particular patient via the communications network;

a processor configured to

analyze said received signal representing patient physiological parameter values, provide data representing a plurality of notifications to an operator, each notification corresponding to an extrapolated patient condition, and trigger said alert indication when a respective notification indicates a predetermined patient physiological parameter value has been reached,

receive a command from an operator to suppress one of said triggered notifications that is not indicative of the patient'"'"'s medical condition, and

recalculate said data representing said plurality of

notifications to exclude said suppressed notification;

a decision processor that applies a decision rule to said extrapolated patient condition derived from said recalculated notifications to identify an alert condition is present; and

an alert generator that generates said alert indication in response to said identified alert condition.

2. A system according to claim 1, wherein

said device uses patient record information for a particular patient in extrapolating patient condition.

3. A medical alarm system for processing information from a plurality of patient monitoring devices adapted to be attached to a patient and having at least one physiological sensor that produces a signal representing at least one patient physiological parameter and transmit the signal via a communications network, the system comprising:

a communication interface configured to receive a signal representing patient physiological parameters from the plurality of patient monitoring devices for a particular patient via the communications network;

a processor configured to

analyze said received signal representing patient physiological parameter values, provide data representing a plurality of notifications to an operator, each notification corresponding to an extrapolated patient condition, and trigger said alert indication when a respective notification indicates a predetermined patient physiological parameter value has been reached,

receive a command from an operator to suppress one of said triggered notifications that is not indicative of the patient'"'"'s medical condition, and

recalculate said data representing said

plurality of notifications to exclude said suppressed notification; and

a generator that provides at least one of, (a) diagnostic and (b) treatment suggestions based on said extrapolated patient condition derived from said recalculated notifications.

4. A system according to claim 3, wherein:

said generator provides user-selectable suggestion information concerning said notification.

5. A system according to claim 4, wherein

said generator associates different reliability weighting to corresponding suggestion information.
