Needle Decompression

If you patient develops a tension pneumothorax, he will need to have the air trapped inside his chest cavity removed before it collapses one or both lungs.

Locate the third intercostal space, between the 4th and 5th ribs, midclavicle.

Clean the affected side or sides. Under dire circumstances I've seen this skipped many times. Its easier to treat an infection later then let someone die right now.

Betadine works well for this. Use one to scrub the area and the second to clean from the inside of the site to the outside.

There are several different techniques and tools available for this. The simplest and most likely available is a large IV angio. A 3 inch long 14 gauge (orange) is best but 16 gauge (gray) will also work. It needs to be longer then the normal IV angio since it must pass through the muscle, fat and other matter before it can reach the lung.

Insert the angio at a 90 degree angle till you hear air escaping. Then advance the catheter into the site, and remove the needle. If you have a NACL syringe, first attach it to the angio and you will see it bubble when you have reached the proper depth. Advance catheter only and remove the syringe. If you hit a rib, go over the top of the rib and not below to not damage the neuro-vascular bundle.

With the angio in place you can either use a premade kit with a 4 way stop cock or you can improvise. The hole made by the angio is very small compared to the trachea. Even if the person did not have a tension pneumothorax you would only cause a minor pneumo which many people suffer from without adverse affect.

If you do not have a premade kit, you can occlude the catheter by inserting the IV through a glove finger first. Lay the glove finger over the angio hole. When the patient breaths in, the finger will occlude the hole. If air builds up it will force past the glove.
