Abstract

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.

Claims

1. a portable manual resuscitation bag system for the emergency administration of cardiopulmonary resuscitation and for patient transport comprising:

a) a deflatable bag having a terminal for connection with a source of oxygen

b) 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,

c) an exhalation port in flow connection with said flow channel

d) an indicator mounted adjacent said system for detecting at least one of exhalation flow and pressure within at least one of said flow channel and said exhalation port.

2. The resuscitation bag system of claim 1 wherein said indicator is elastomeric.

3. The resuscitation bag system of claim 1 wherein said indicator is a flow indicator.

4. The resuscitation bag system of claim 1 wherein said indicator is a pressure indicator.

5. The resuscitation bag system of claim 1 wherein said indicator is mounted adjacent said exhalation port.

6. The resuscitation bag system of claim 2 wherein said indicator is a visual indicator.

7. The resuscitation bag system of claim 1 wherein said indicator is an auditory indicator.

8. The resuscitation bag system of claim 1 wherein said indicator is a pneumotachometer.

9. An improved method of bagging a patient during cardiopulmonary resuscitation using disposable manual resuscitation bag system, the system including a deflatable bag having a terminal for connection with a source of oxygen, said system further having a flow channel connected with said bag, for connection with an indwelling endotracheal tube, said flow channel providing for the flow of gas from the bag into the patient and from said patient through said flow channel, said flow channel having an exhalation port in flow connection with said flow channel, the method comprising steps of:

a) disposing, adjacent said system, an indicator of at least one parameter indicative of persistent flow of gas through at least one of said flow channel and said exhalation port,

b) deflating said bag by applying compressive force to said bag to induce flow through said conduit to inflate a patients lungs,

c) releasing said compressive force, said patient passively exhaling said gas through said conduit and out said exhalation port,

d) monitoring said at least one parameter and adjusting time allowed for exhalation based on said monitoring.
