have you ever wondered how you would treat a sucking chest wound? Always heard about using the wrapper from trauma dressings and tape...... Well my friends there is a simpler solution to this problem. The Asherman Chest Seal - super sticky, one piece unit that can even be applied to yourself in case you get hit. The advantages the ACS has over the old method is speed and ease of use - it is peel and stick simplicity, critical in situations where the fur is still flying while you are performing your medic magic. I have found them online for about $12 each. Food for thought.
