@@truehope287 Excessive cold or heat will more than likely degrade the vent inside. I would keep it inside to be safe.

How does this stop bleeding.

Thank you for the video. Just bought a pack in case I need to be me or my family's own first responder

[@Gunit0121]

Thank you..got mine from Tactical Rifleman...little advertisement. I sure do appreciate the video..the what if scenario

[@DrJonez]

How tolerant of heat/cold are these? Wondering if storing one in my car first aid kit would be ok. I feel like the summer heat and winter cold would break down the adhesive though? Can't seem to find any information on this.

[@IntoTheWildernessBushcraft]

Thank you for the info. I have 2 of these.

[@dyscea]

It’s great to have all these awesome products for my go bag or emergency kit. But might be rendered useless if I don’t know how to use them properly. 😆 Thx for the instructional!!

Thanks for sharing MDA

[@fraflorescl]

In the scenario where the gunshot has an exit hole at the back of the victim. Should I use both chest seals? I mean, one on the front (entry hole) and one on the back (exit hole)? For example, in a case of 9x19mm parabellum shoot

[@senboc]

Trying to use one of these but KZbin decided to give me a double ad.

[@Mike-ww3bq]

Dude that’s just gotta be a real pain in the chest 😅

[@Lezura]

A year late to your comment, sorry, but the product is simply plastic with an adhesive backing, there should be no issues with cold weather, however the adhesive may degrade over time.

[@spacedaddycereal73]

A few questions.. do i use a gauze to plug the hole, then apply the seal? If there's a exit wound would i do the same for that wound also or just apply chest seal only to both wounds?

[@NineEyedCyclops]

You do NOT pack the wound with the gauze first. The chest seal is designed to allow the exhalation of air through the wound to reduce the chance of tension pneumothorax. It won't hurt to place these chest seals on any chest wound, but prioritize the wounds depending on their location. If there is only one entry/exit, you can use chest seals on both sides, provided that the blood flow is not heavy. Heavy blood flow - Pack and Pressure. In general, the closer the wound is to the lungs takes priority. Next, prioritize one on each the left and right side if there are multiple gunshot wounds to the chest. Any other wounds after this could be packed with gauze and/or pressure applied until EMS arrives. Then, if the patient is falling out, do CPR (chest compressions only). Also, check the legs to see if there is any significant blood loss that needs pressure / a tourniquet. Best of luck, and stay calm.

[@isheworthy]

NEVER pack an open chest wound with gauze unless there is serious uncontrolled bleeding.

[@nicolasm.bronner2747]

very nice! Thanks for the video. I have a doubt though... in the video, it looks like the seal applied on the pectoral of the victim is having 3 ways where blood can flow out, so it's not really sealed, or is it just an impression ?

[@Noahs_Crazy_Kid]

It is vented. By design. It’s designed to let pressure out but not in. This helps protect from unwanted pressure building up inside the body which could cause a collapsed lung. It’s basically a one way valve. That’s why it’s called a vent chest seal. Hope this helps. Stay safe.

[@nicolasm.bronner2747]

@@Noahs_Crazy_Kid Thanks a lot for the clear explanation :)

[@dyscea]

The package says “vent” on it. I wonder if they still make them unvented. Something to look out for!

[@xavierbreath2227]

I see both vented and non vented chest seals available. When do you use one vs the other?

[@ek8652]

Can I open both packs and combine them to save space in a pocket ifak?

[@petercho546]

I dont understand. Is this all you would do to a chest wound? If air can escape but not go in, doesnt that mean blood can escape? Therefore making this useless as it solves the pneumo, but doesnt stop the bleeding? I thought stopping the bleed was the priority Edit: Also, it looks like the 3 vent tubes/openings dont have any way to close? How does it close when air is being sucked in?

[@dyscea]

Hope someone more knowledgeable would jump in, but I’ll share my thoughts. Air is more important than blood. I mean, blood is pretty close behind, tho. So deal with that next! The plastic should be close enough to the skin that it gets sucked in on the inhale, making a good seal. And all we’d be doing is just allowing an injured person to survive to have the EMTs come. The EMTs are allowing the them to survive until they get to a surgeon. Edit: I don’t think that’s that much blood in a chest wound for concern with blood loss (for awhile). Not like hitting a major artery.

[@Pugrug.]

Stopping massive hemorrhage is important but you can’t do much outside of an operating room. You need to repair organs and if blood vessels are hit, you can’t pack the chest because there is no solid tissue. The way the seal works is when you exhale the vents are open, but when you in hale the negative pressure in the chest closes the vents. It’s kinda like when you try to breath with a plastic bag over your mouth. You can blow air out but once you breath in the bag seals against your mouth. Same concept with seals.

[@Nerdelkin]

You can't do pretty much anything to stop bleeding in case of chest/stomach injuries outside of hospital. With chest ones you just can make sure to prevent pneumothorax with chest seal and only IF you're trained with a decompression needle. And in case with stomach wounds you can only cover it with non pressing bandage. And if there is a penetrating object, i.e. knife, making sure it doesn't move but never pull anything out. So yeah, pretty much you can just do that and pray nothing major is damaged.

[@NiqHowie]

So if theres an entrance and exit wound, would you want to place a seal on both sides? And when would you burp it?

[@carsongrube5491]

sorry to respond late but yeah you would want to seal both sides, both front and back wounds can give you a sucking chest wound which is a big no no.

[@richardhaas1555]

Only burp if difficulty breathing increases and or decreased lung sounds on the affected side or tracheal deviation, which is an extremely late sign of a tension pneumo... If you are a medic you will dart the affected side if the symptoms persist.

[@fastbern]

I have been told by several trauma Docs that a chest seal is not necessary unless you have a dart. Thoughts ?

[@UnfiItered]

Both are needed and should be taught by professional medics. Old chest seal(not vented) stop air from going in but also prevent blood and air pressure from coming out. With the new vented chest seal, they fixed that. You can still get tension hemithorax, so knowing how to use a "dart" is important to relive the hemithorax.

[@roosdad1]

Why didn't you pick someone with chest hair? I give this a (3)

[@isheworthy]

Because a guy with chest hair would experience some issues getting that thing off. XD In real life, use a razor to shave the area first (if you have time). This should ideally only take a few seconds. If not, just slap the seal on and hit the road.
