Cardiopulmonary resuscitation assisting apparatus

A cardiopulmonary resuscitation assisting apparatus which assists cardiopulmonary resuscitation when the cardiopulmonary resuscitation is performed on a target, the apparatus comprising:

• a first sensor which detects acceleration of movement of a compressed part of the target due to compression operation;
• a second sensor which outputs information corresponding to a magnitude of compression on the compressed part of the target due to the compression operation;
• a first calculation section which obtains a relational expression between a compression depth calculated based on second-order integration of the acceleration information acquired from the first sensor, and the information corresponding to the magnitude of the compression acquired from the second sensor;
• a determination section which differentiates the relational expression with respect to an output value of the second sensor and compares a resulting differentiated value of the relational expression with a predetermined threshold to thereby determine whether notification for assistance of cardiopulmonary resuscitation is necessary or not;
• and
• a notification section which performs the notification for assistance of cardiopulmonary resuscitation when determination is made by the determination section that the notification is necessary.
