This torso allows an instructor to teach and a student to practice properly inserting a needle to permit built up air pressure to escape the thorax. Emergency care doctors recommend this relatively simple procedure to release air pressure from the thorax of a trauma victim. This model will allow emergency medical personnel to develop the needed skills before administering to a live patient. This model accepts needle thoracotomy in the second intercostal space in the midclavicular line, or the fifth intercostal space in the mid-axillary line. The model is complete with replaceable lungs, a rib cage, and a soft, lifelike replaceable skin. Unit can be punctured 75 to 100 times before replacement is necessary. Three-year warranty.
