Pneumothorax - not realistic with Thoracentecis treatment!

I'm no doctor, and I also don't know how realistic you want the game to be, but Thoracentecis is not what you use for a Pneumothorax!
And no USG-device either.

Thoracentecis on the other hand can CAUSE a Pneumothorax (or even worse, a Tension Pneumothorax, or Hemothorax, or Hemopneumothorax if those are in the game).

Thoracentecis (never heard of before today) seem to be a pretty quick procedure where you tap out water surrounding the lungs.

For any kind of Pneumo/Hemothorax though, you use a chest tube or similar.
Different ways/procedures, but I think most hospitals still put a tube under/through your ribs, and connect you to a machine with continous suction for a few days that slowly removes air/blood. Others can get a mobile drain attached to the chest and be treated at home and then come back after 5 days to remove it, but that probably won't suit the game as well.
Discomfort should definitly be "high", unless you have "very high" too...

Maybe you could make a quick google, or consult with some doctor, and update procedure in the game? If you think it's necessary that is!

Also, I don't think many doctors would want to have a pneumothorax-patient ventilated, that's kind of dangerous! Happened to my guy at the hospital just now!
But don't trust me 100%, confirm that with someone. I think it's very very dangerous though!

A chest tube is a hollow, flexible tube placed into the chest. It acts as a drain. Chest tubes drain blood, fluid, or air from around your lungs, heart, or esophagus. The tube around your lung is placed between your ribs and into the space between the inner lining and the outer lining of your chest cavity.

Uhm...I just read that you use Thoracentecis is relieving pressure from the (collapsed) lung by removing air or liquid with a needle.
However, if the fluid makes lung and heart operate worse the proper indication would be tube thoracostomy - a chest tube. You get this, when you have the symptom of significant pleural efflusion or a severe pneumothorax (air is the problem) or haemothorax (there is blood causing the problem).

I think for 'soft' cases, the Thoracentecis with the needle is the bread-and-butter solution while the chest tube is for critical cases.
Some diseases in the game seem to have optional symptoms depending on severity and complications i.e. not treated symptoms deteriorating over time.

Maybe get some medical counsel and take a second look at the procedure @devs.

Anyway, you don't use it for a pneumothorax.
With pneumothorax you have a leak in the lung, you need to inflate the collapsed lung and treat it for a while, with a chest tube or similar.
If you've instead had some bacteria or whatever that made you get water in the pleural space, you just tap in and drain it into a plastic bag - that is Thoracentecis.
Something pretty different I would say!

A chest tube is not anything exotic or strange, it's something that could really have it's (small) place in this game

But best with a real doctor to consult them. Anyway the changes made to the game could be kept pretty small and simple.

EDIT: They could just skip the USG-device for all pneumothoraxes, and change the treatment to "chest tube", and write a description.
And (most probably) stop having them ventilated, at all cost!
Forcing down air into the lungs is the last thing you want to do if someone has a punctured lung.

I found this article on the topic very informative: https://www.healthline.com/health/collapsed-lung#treatments
