A couple of points, clarifications:
A needle thoracentesis to decompress a tension pneumothorax is relatively easy to do, but requires some assessment skills to know when and where to do it. The stethoscope is very useful for that. The IV catheter JI mentions may be useful for others to use who have such skills, but don't have the needed equipment at the time of need.

The rare person who has a spontaneous pneumothorax (without a penetrating wound, mostly tall skinny adolescents), will not be helped by a chest seal: There is nothing to seal on the skin. For relief, the needle thoracentesis provides the quickest relief and can sometimes avoid need for a chest tube.

A one-way flap valve can be fashioned from a nitrile or latex glove finger cut off from the glove to fit over the hub of the thoracentesis needle/catheter and secured in place to prevent air -reentry.

Emergency cricothyroidotomies are really rare; done mainly for acute upper airway obstruction from a suddenly swollen epiglottis, or massively swollen tongue, or a hangman's injury, etc. The trachea is what is intentionally punctured, not the esophagus: One more reason to carry a small very sharp blade, and a pen, which can be disassembled and the longer part of it thrust thru the new opening in the trachea to allow air-exchange. Again, someone else at the scene may have the skills, but not the equipment needed.

YouTube of course has the videos.

The American College of Surgeons Advanced Trauma Life Support course and Tactical Combat Casualty Courses cover these techniques, but these courses may be very difficult to access if you are not in medicine/nursing/EMT/Paramedic/firefighting/law enforcement already.
