Continuous patient monitoring
View Patent ↗A system for providing continuous monitoring of a patient includes: a first monitor device configured to measure one or more physiological attributes associated with the patient, the first monitor device being a contactless device; and a second monitor device configured to measure one or more physiological attributes associated with the patient, the second monitor device including one or more sensors contacting the patient; wherein, upon an alarm condition by the first monitor device, the second monitor device is configured to measure a physiological attribute and suppress the alarm condition when the second monitor device detects a non-alarm condition.
1. A system for providing continuous monitoring of a patient, the system comprising:
a first monitor device configured to measure one or more physiological attributes associated with the patient, the first monitor device being a contactless device; and
a second monitor device configured to measure one or more physiological attributes associated with the patient, the second monitor device including one or more sensors contacting the patient;
wherein, upon an alarm condition indicating an abnormality by the first monitor device, the second monitor device is configured to measure a physiological attribute and suppress the alarm condition when the second monitor device detects a non-alarm condition; and
wherein the second monitor device allows the alarm condition when the second monitor device detects an alarm condition.
2. The system of claim 1 , wherein the first monitor device includes a piezoelectric device.
3. The system of claim 2 , wherein the piezoelectric device is positioned under a mattress or cushion of a structure upon which the patient is laid.
4. The system of claim 3 , wherein the piezoelectric device detects the patient's heart rate, respiration rate, and patient movement.
5. The system of claim 1 , wherein the second monitor device inflates a blood pressure cuff to estimate movement of the patient.
6. The system of claim 5 , wherein the blood pressure cuff is inflated to a sub-measurement pressure.
7. The system of claim 1 , wherein suppression of the alarm condition by the second monitor device is limited to a specified time period.
8. The system of claim 7 , wherein the second monitor device allows the alarm condition to be transmitted when the specified time period expires and the first monitor device continues to issue the alarm condition.
9. A system for providing continuous monitoring of a patient, the system comprising:
a first monitor device configured to measure one or more physiological attributes associated with the patient, the first monitor device being a piezoelectric device that measures the physiological attributes without contact, and wherein the physiological attributes including heart rate, respiration rate, and patient movement; and
a second monitor device configured to measure one or more physiological attributes associated with the patient, the second monitor device including one or more sensors contacting the patient;
wherein, upon an alarm condition indicating an abnormality by the first monitor device, the second monitor device is configured to measure a physiological attribute and either:
(i) suppress the alarm condition when the second monitor device detects a non-alarm condition; or
(ii) allow the alarm condition when the second monitor device detects an alarm condition; and
wherein the second monitor device inflates a blood pressure cuff to a sub-measurement pressure to estimate movement of the patient and detects the non-alarm condition when movement of the patient is detected.
10. The system of claim 9 , wherein the piezoelectric device is positioned under a mattress of a bed upon which the patient is laid.
11. The system of claim 9 , wherein suppression of the alarm condition by the second monitor device is limited to a specified time period.
12. The system of claim 11 , wherein the second monitor device allows the alarm condition to be transmitted when the specified time period expires and the first monitor device continues to issue the alarm condition.
13. A method for continuously monitoring a patient, the method comprising:
measuring a first physiological attribute using a first monitor device, the first monitor device being a contactless device;
detecting an alarm condition indicating an abnormality by the first monitor device;
measuring a second physiological attribute using a second monitor device, the second monitor device including one or more sensors contacting the patient, and the measuring including:
inflating a blood pressure cuff;
estimating movement of the patient based upon a pressure characteristic as measured by the blood pressure cuff, the pressure characteristic including a pressure increase or decrease indicative of movement; and
determining a non-alarm condition when movement of the patient is detected;
suppressing the alarm condition when the second monitor device detects the non-alarm condition; and
transmitting the alarm condition when the second monitor device detects an alarm condition.
14. The method of claim 13 , wherein the first monitor device includes a piezoelectric device.
15. The method of claim 14 , further comprising positioning the piezoelectric device under a mattress of a bed upon which the patient is laid.
16. The method of claim 13 , further comprising trending data from the first and second monitor devices to determine a state of recovery for the patient.
