PerSys S.O.S. Definitely Add This To Your IFAK!


PerSys has introduced a dressing that I’ll simply describe as fast-food for treatment of an open chest wound. It address all of the important issues encountered by anyone attempting to deal with an open chest wound in less than optimal conditions. Add the S.O.S to your medical kit!

PerSys S.O.S., is an advanced occlusive dressing developed for the treatment of open chest wounds and for the prevention of tension pneumothorax.

The PerSys S.O.S. utilizes an ultra-strong, medical-grade hydrogel adhesive which clings to skin despite blood, sweat, hair, sand, or water. The dressing’s four vent design allows for one-way airflow out of the chest cavity during exhalation, while preventing airflow into the chest cavity during inhalation.

Unlike more complicated “valve systems” which are prone to clogging, the rugged simplicity of the S.O.S. stands up to water, sand, mud, debris, and bodily fluids. The dressing’s compact packaging and 3 year shelf life make it an ideal component of any kit.
