The first "sign" would probably be a hole with blood coming out of it. The first "symptom" would probably be the patient screaming in pain.
If you are not sure if a chest wound has penetrated the chest wall completely, treat the wound as though it were an open chest wound.
An Open Chest Wound (Sucking Chest Wound)
Difficulty breathing, jugular vein distention, tracheal deviation, and decreased breath sounds.
Umm, well if it was an open chest wound..there would be an obvious HOLE/CUT in your chest. you would be able to see it.
Let's see...difficulty in breathing, a sucking sound when the victim tries to, lots of blood on the chest part of his uniform, and big holes in the troop's chest are all symptoms of an open chest wound. One thing that must be pointed out: Open chest wounds in combat often come in pairs - one on the front where the bullet entered, one on the back where it exited. Make absolutely sure you check for that second one; patching up one sucking chest wound won't help the soldier breathe better if he has two.
pain, blood coming from the chest,
There will most likely be a large gash in the chest, and a symptom is bleeding and/or crying.
All of the above sabc
Hmmm...difficulty breathing, profuse bleeding from the area where the wound is, and a big hole in the guy's chest that shouldn't be there.
Coughing up blood, sucking or hissing sounds coming from a chest wound, frothy blood appearing from air bubbles coming from the wound

There shouldn't be a knot to tie. The treatment for an open chest wound is to put a piece of plastic over it and tape it down on the sides so that air cannot get in or out of the wound. There's nothing to tie down anywhere in that. You could be thinking of flail chest which has more to do with broken bones then an open chest wound. As an army medic I find your question soul crushingly confusing.
