The manikin has the tried and tested mechanical monitoring instrument that gives you instant feed back on ventilation volume, stomach inflation, chest compression depth and wrong hand position. Chest rigidity is adjustable so that different body builds can be simulated. Flexible defib electrodes so that you can train with all leading brands of defibrillators. Intubation with ordinary oral tube, Laryngeal mask and Combitube, defibrillation, ECG lead diversion and IV training can be trained on the manikin making the training scenario realistic. Optional Ambu CPR Software Kit and Printer can be added. The Ambu ECG Box simulates as many as 26 rhythms and 2 artefacts giving you a wide variety of ECG options. The ECG Box has two optional power sources: an internal battery pack, or an external 9V adapter giving you the flexibility to train on location and the security of knowing that the system will always work even if the batteries are low or missing.
