Monitoring cpr by a wearable medical device

Abstract

A wearable medical device comprises a garment configured to be worn about a torso of a patient. The wearable medical device further comprises a CPR sensor for detecting a characteristic of a CPR therapy provided to the patient. The CPR sensor is coupled to the garment to provide movement between a stowed position and a deployed position. The CPR sensor is positioned at a center of a chest of the patient when the CPR sensor is in the deployed position. The wearable medical device further comprises an output device. The wearable medical device further comprises a processor configured for processing information from the CPR sensor and providing, to the output device, information about the CPR therapy provided to the patient.

         91 . A wearable medical device, comprising:
 a garment configured to be worn about a torso of a patient;   a CPR sensor for detecting a characteristic of a CPR therapy provided to the patient, the CPR sensor being coupled to the garment to provide movement between a stowed position and a deployed position, wherein the CPR sensor is positioned at a center of a chest of the patient when the CPR sensor is in the deployed position;   an output device; and   a processor configured for processing information from the CPR sensor and providing, to the output device, information about the CPR therapy provided to the patient.   
     
     
         92 . The wearable medical device of  claim 91 , wherein:
 the garment comprises a flap; and   the flap and the CPR sensor are configured to allow for the movement between the stowed position and the deployed position.   
     
     
         93 . The wearable medical device of  claim 92 , wherein:
 the garment further comprises a belt;   the flap is attached to the belt; and   the movement causes the flap to fold away from the belt and be positioned at a location above a xiphoid process of the patient.   
     
     
         94 . The wearable medical device of  claim 92 , wherein the characteristic of the CPR therapy comprises one or more of a chest compression depth or a chest compression rate. 
     
     
         95 . The wearable medical device of  claim 92 , wherein the CPR sensor is attached to the flap using a hook-and-loop fastener. 
     
     
         96 . The wearable medical device of  claim 92 , wherein the processor is further configured to provide, via the output device, instructions for a rescuer to move the CPR sensor from the stowed position to the deployed position before initiating the CPR therapy. 
     
     
         97 . The wearable medical device of  claim 92 , wherein:
 the garment comprises a belt and a shoulder strap; and   the flap is attached to the belt.   
     
     
         98 . The wearable medical device of  claim 97 , wherein the flap and the CPR sensor are positioned in front of the belt when the CPR sensor is in the stowed position. 
     
     
         99 . The wearable medical device of  claim 92 , wherein the flap is pivotable between the stowed position and the deployed position. 
     
     
         100 . The wearable medical device of  claim 91 , wherein the garment comprises a pocket configured to receive the CPR sensor when the CPR sensor is in the stowed position. 
     
     
         101 . The wearable medical device of  claim 100 , wherein the CPR sensor is configured to wirelessly communicate with the processor. 
     
     
         102 . The wearable medical device of  claim 100 , wherein the garment further comprises a pivoting flap having the CPR sensor attached thereto. 
     
     
         103 . The wearable medical device of  claim 102 , wherein the CPR sensor is attached to the pivoting flap using a snap fastener. 
     
     
         104 . The wearable medical device of  claim 100 , wherein:
 the garment comprises a waistband and a shoulder strap; and   the pocket is provided on the waistband.   
     
     
         105 . The wearable medical device of  claim 104 , wherein the CPR sensor is positioned at a central portion of the waistband when the CPR sensor is in the stowed position. 
     
     
         106 . The wearable medical device of  claim 104 , wherein the waistband is positioned over a rib of the patient when the patient wears the garment. 
     
     
         107 . The wearable medical device of  claim 100 , wherein the characteristic of the CPR therapy comprises one or more of a chest compression depth or a chest compression rate. 
     
     
         108 . The wearable medical device of  claim 100 , wherein the processor is further configured to provide, via the output device, instructions for a rescuer to remove the CPR sensor from the pocket and position the CPR sensor in the deployed position before initiating the CPR therapy. 
     
     
         109 . The wearable medical device of  claim 91 , wherein the processor is further configured to provide, via the output device, instructions for a rescuer to move the CPR sensor from the stowed position to the deployed position before initiating the CPR therapy. 
     
     
         110 . The wearable medical device of  claim 91 , wherein the CPR sensor is configured to wirelessly communicate with the processor.
