In conjunction with the opening of the American Society of Anesthesiologists annual meeting in Boston, Mindray has announced the introduction of its Neuromuscular Transmission (NMT) Module for its Passport 17m and 12m monitors. The NMT Module provides a stimulus to a nerve in the hand and measures the response to that stimulus. The response provides an indication of the level of muscle relaxation in the patient under a neuromuscular blockade.
