The Smart Bag MO has been designed to allow the provision of consistent ventilations while almost completely eliminating the risks associated with conventional BVM ventilation. The unique actuating mechanism hidden inside the neck bushing of the SMART BAG MO actually responds to the rescuer and the patient.
By responding to the rescuer’s squeeze and release of the BVM, the SMART BAG MO limits the excessive flow of gas into the patient’s airway, significantly reducing the risk of gastric insufflation by effectively lowering the airway pressure generated. In a normally compliant and resistant airway, the airway pressure is limited to below the esophageal sphincter opening pressure of 19 cm H2O.
The response by the SMART BAG MO is proportional to the rescuers squeeze. The harder the squeeze, the grater the restriction to flow. This alerts the rescuer to ease up on the squeeze, reducing the effort required, resulting in the airway pressure being kept to the minimum to achieve adequate ventilation. At no time is the flow of gas into the patient compromised by the SMART BAG MO, allowing the rescuer to ventilate even the stiffest lung or most restrictive airway.
To assist the rescuer a visual warning of incorrect ventilation technique of the SMART BAG MO is provided. If the SMART BAG MO is squeezed too hard, the SMART BAG MO responds by closing the value to lower the flowrate. Should this occurs the “red pressure actuating indicator” moves to the forward position in the neck of the patient value producing a visual warning of improper technique.
If the patients airway is less compliant or more restrictive (as in patients with COPD or asthma), higher airway pressures will be required to provide adequate ventilation. In responding to this increased pressure required in the patient’s airway, the SMART BAG MO decreases the resistance to flow from the BVM, balancing the pressure on either sidi of the value. This allows the required pressure to be exerted by the rescuer on the patient’s airway to overcome the resistance / compliancy problem and provide adequate ventilations.
The SMART BAG MO is equipped with a manual override control to disable the action of the SMART Valve. Current research indicates that, for all patient conditions, the manual override control should not be used and the “SMART VALVE” should be left in the “Enabled” position. This recommendation maintains operation of the device in strict compliance with the correct Guidelines for CPR and ECC as published by the American Heart Association and European Resuscitation Council.
To ensure correct operation of the manual override, do not switch into disabled mode which squeezing the bag.
