Ambu's patented hygienic system protects the student and makes internal cleaning entirely unnecessary. The stiffness of the chest is infinitely variable, allowing students to train on different body builds. Airways open only when head is correctly hyperextended. A carotid pulse can be activated manually by the instructor. It is also activated during chest compressions. The lifelike anatomy makes it suitable for training of correct placement of defib pads in training use of Automated External Defibrillators (AED). AmbuMan has the tried and tested mechanical monitoring instrument that gives you instant feedback on ventilation volume, stomach inflation, chest compression depth and wrong hand position. PC connection is possible via the Ambu CPR Software Kit (sold separately). In addition the Ambu I.V. Trainer Arm (also sold separately) can be mounted. You can also purchase an upgrade kit so that your BLS manikin can also function as an early defibrillation manikin. The monitoring instrument included in model C is available according to Guideline 2005 (AHA, ARC, ERC, CLAR, NZRC and RCSA)recommendations. All manikins are delivered with 5 face pieces and 100 head bags in a soft carry bag that can be used as a training mat.
