Inspiratory Muscle Strength Training in Infants With Congenital Heart Disease and Prolonged Mechanical Ventilation: A Case Report by Barbara K. Smith, Mark S. Bleiweis, Cimaron R. Neel, and A. Daniel Martin ptjournal Volume 93(2): February 1, 2013 © 2013 American Physical Therapy Association
Devices used to evaluate and train inspiratory muscle strength: (A) A unidirectional valve and respiratory monitor adapter was attached directly to the end of the endotracheal tube to measure maximal inspiratory pressure.
