心肺復甦術訓練按壓回饋方法

Disclosed is a compression feedback method for cardiopulmonary resuscitation training, comprising: setting a three-axis accelerometer at a preset compression position in the chest cavity of a dummy for cardiopulmonary resuscitation training to sense the compression action of a trainee, and calculating the pressing frequency of the pressing action, the pressing depth, the offset orientation of the actual pressing position, and the offset distance of the actual pressing position. The X and Y axis acceleration values ​​sensed by the three-axis accelerometer are input into a so-called rotation angle formula to calculate a rotation angle θ so that the offset orientation of the actual pressing position is obtained. In addition, an inclination angle φ of the Z axis sensed by the three-axis accelerometer is calculated, and the offset distance of the actual pressing position is obtained by a linear regression equation that is established in advance.
