Abstract

A system and method for the automatic diagnosis of obstructive sleep apnea in a centralized hospital critical care monitoring system for the monitoring of a plurality of patients in at least one of a critical care, step down, and cardiac ward by telemetry. The system includes a central processor having a display, and a plurality of telemetry units for mounting with patients, each of the telemetry units has a plurality of sensors for connection with each patient, the telemetry unit is capable of the transmission of multiple signals derived from the sensors to the central processor, in one preferred embodiment the method comprising steps of programming the system to analyze the signals and to automatically identify the presence and severity of obstructive sleep apnea and to provide an indication of the identification.

Claims

1. A method for the automatic detection of obstructive sleep apnea in a centralized hospital critical care monitoring system for the monitoring by telemetry of a plurality of patients in at least one of a critical care ward and a hospital ward, the system including a central processor having a display, and a plurality of telemetry units for mounting with said patients, each of said telemetry units having a plurality of sensors for connection with each said patient, each of said telemetry units transmitting a plurality of signals to said central processor, the method comprising the steps of:

a) programming said system to analyze said signals and to-automatically identify at least one of the presence and severity of obstructive sleep apnea,

b) programming said system to output an indication of said identified obstructive sleep apnea; and

c) programming said system to communicate with an intravenous infusion system to prevent the progression of said identified obstructive sleep apnea by limiting infusion of a narcotic.

2. A method for providing automatic detection of upper airway instability in hospitalized patients who are being otherwise routinely monitored with a centralized hospital monitoring system, in at least one of an acute care environment or a surgical hospital environment, so that the routine monitoring provides automatic screening for upper airway instability, the method comprising the steps of:

a) programming said centralized system to automatically identify the presence of upper airway instability;

b) programming said centralized system to output an indication of said identified upper airway instability; and

c) programming said centralized system to communicate with an intravenous infusion system to prevent the progression of said identified upper airway instability by limiting infusion of a narcotic.

3. The method of claim 2, further comprising the steps of:

a) programming said centralized system to automatically identify the presence of obstructive sleep apnea; and

b) outputting an indication of said identified obstructive sleep apnea.

4. The method of claim 2, wherein said method further comprises the step of:

programming said centralized system to provide a graded indication based on said identified upper airway instability.

5. The method of claim 2, wherein said method further comprises the step of:

programming said centralized system to communicate with a system for intravenously infusing a medication.

6. The method of claim 2, wherein said method further comprises the step of:

programming said centralized system to communicate with an airway pressure delivery system for treatment of airway instability.

7. A method for facilitating case finding of obstructive sleep apnea in hospitalized patients who are being otherwise routinely monitored with a centralized hospital monitoring system in at least one of an acute care environment, a sub acute care environment and a surgical hospital environment, the method comprising:

a) programming said centralized system to provide a printed output that is formatted to optimize the visual detection of patterns indicative of the presence of obstructive sleep apnea disease, so that routine hospital monitoring renders printed outputs that can be readily interpreted to routinely detect the presence of obstructive sleep apnea disease; and

b) programming said centralized system to communicate with an intravenous infusion system to reduce the progression of an identified upper airway instability by limiting the infusion of a narcotic.
