These are mannequins that combine the two functions (CPR & Choking) in one mannequin: It allows switching between CPR training mode and normal airway obstruction simulation mode. It may include additional features such as carotid artery pulse simulation to enable the trainee to check vital signs. Its features include: - Simulation of normal airway obstruction. - Ability to perform CPR maneuvers, airway opening, and chest compression simulation. - Training on adult first aid surgery in Heidagger. - Carotid artery pulse simulation. According to the degree of compression strength, the trainee can distinguish between the degree of pulse and the frequency of the carotid artery. - Individual replacement of mouth and nose pieces, as each set contains 3 mouth and nose pieces. - Net weight: 7 kg.
