Apparatuses for supporting and monitoring a condition of a person
View Patent ↗A person monitoring system is operable to predict the onset of an adverse condition of a person. The system receives first information corresponding to a feature of a person support apparatus and second information corresponding to a physiological characteristic of the person. The system calculates a condition score as a function of the first and second information. In some instances, the system alerts a caregiver if the condition score exceeds a predetermined threshold. Alternatively or additionally, the person monitoring system alerts a caregiver when a person supported on a person support apparatus is regaining consciousness by monitoring one or more of a change in position, a heart rate, and a respiration rate. A person monitoring system that monitors a person's quality of sleep and presents information concerning the quality of sleep to one or more interested parties is also disclosed.
1. A method of predicting the onset of an adverse condition, the method comprising:
receiving at a controller at least one data signal from a tissue contacting sensor and a non-tissue contacting sensor, the tissue contacting sensor being included as part of a person support apparatus having a surface sufficiently large to accommodate an entirety of a body of a person in a lying position, the tissue contacting sensor being located underneath a torso of the person when the person is lying on the surface facing upwardly, the non-tissue contacting sensor being located below the tissue contacting sensor and below the surface when the person is lying on the patient support apparatus facing upwardly;
calculating using the controller a condition score as a function of the at least one data signal; and
alerting using the controller a caregiver if the condition score is greater than a predetermined threshold.
2. The method of claim 1 , wherein the predetermined threshold is a function of information from at least one of an electronic medical record, a patient profile, and a caregiver.
3. The method of claim 1 , wherein the tissue contacting sensor is configured to measure blood pressure, tissue temperature, tissue blood oxygen content, heart rate, or respiration rate.
4. The method of claim 1 , wherein the non-tissue contacting sensor is configured to measure person support apparatus status, bladder pressure, heart rate, respiration rate, relative humidity, or an amount of force on a person support surface.
5. The method of claim 1 , wherein the condition score is calculated as a function of a status signal of the person support apparatus.
6. The method of claim 1 , wherein the non-tissue contacting sensor is included as part of the person support apparatus.
7. The method of claim 1 , wherein the condition score is a Visensia index.
8. The method of claim 1 , wherein the controller is configured to receive information from an electronic medical record (EMR), the controller calculating the condition score as a function of the at least one data signal and the information.
9. The method of claim 1 , wherein the tissue contacting sensor is integrated into a person contacting surface of the person support apparatus.
10. The method of claim 1 , wherein the controller is configured to calculate the condition score as a function of a physiological characteristic and a characteristic or status of the person support apparatus.
11. The method of claim 1 , wherein the controller is configured to receive information from a patient profile, the controller calculating the condition score as a function of the at least one data signal and the patient profile information.
12. The method of claim 1 , wherein the controller calculates the index as a function of information from at least one of an electronic medical record, a patient profile, and the at least one data signal.
13. The method of claim 1 , wherein a support apparatus parameter is displayed as a picture.
14. The method of claim 1 , wherein the condition score is displayed as a graph or a picture.
15. The method of claim 1 , wherein the condition score is a modified early warning score based on at least one of caregiver inputs and information from an electronic medical record.
16. A system to predict the onset of an adverse condition, the system comprising:
a patient support apparatus having a surface sufficiently large to accommodate an entirety of a body of a person in a lying position and having a controller that receives at least one data signal from a tissue contacting sensor and a non-tissue contacting sensor, the tissue contacting sensor being included as part of the person support apparatus, the controller being configured to calculate a condition score as a function of the at least one data signal, the tissue contacting sensor being located underneath a torso of the person when the person is lying on the surface facing upwardly, the non-tissue contacting sensor being located below the tissue contacting sensor and below the surface when the person is lying on the patient support apparatus facing upwardly; and
a remote computer device that receives an alert message if the condition score is greater than a predetermined threshold, the controller being configured to initiate the alert message being sent.
