Resistance indicates that the gastric balloon has engaged the
cardia and fundus of the stomach ( Fig. 41-5 ).
To maintain proper position of the gastric balloon, apply
continuous traction.
Accomplish this by using an overhead frame and pulley system,
a football helmet or catcher ’ s mask, or the sponge rubber cuff
(provided in most kits) for patients
who underwent nasogastric insertion. Of these methods, the
pulley system is preferred to deliver the recommended 0.5 to
1.0 kg of traction. If the emergency physician does not have
the weights required for a pulley system, a 1-L bag of crystalloid
solution conveniently provides 1 kg of traction
( Fig. 41-6 ).
