A resuscitation system for the administration of cardiopulmonary resuscitation of asthma patients, and for teaching the cardiopulmonary resuscitation of asthma patients. The invention includes a deflatable bag and a gas flow channel connected with said bag, for connection with an indwelling endotracheal tube so that gas can flow from the bag into the patient and from said patient through said flow channel, an exhalation port in flow connection with said flow channel and an indicator mounted adjacent said system for detecting expiration flow and/or pressure within at least one of said flow channel and exhalation port to detect inadequacy in the expiratory component of ventilation during CPR and to train healthcare workers in the emergency ventilation of severe asthmatic patients in the field and emergency room.
