Use a Chest drain on the chest for Hemothorax. The moodle describes blood accumulating in the pleural cavity because of internal bleeding, progressively impairing breathing. A dressing on an arm does not address that chest condition.
The targeted procedure
- Open the health panel and confirm the Hemothorax warning.
- Select a Chest drain and use it on the chest.
- Recheck the warning, respiratory rate and blood oxygen afterward.
- Also investigate the internal bleeding that caused the accumulation.
The item description says it reduces hemothoraces and is reusable after some time. It does not specify a precise cooldown here, so do not assume you can repeat it instantly or quote a made-up number.
Draining is not the entire diagnosis
Low breathing can also follow severe thorax muscle damage. The First Aid course uses a bruise kit on the thorax to restore muscle health and breathing in that scenario. Check whether the moodle, muscle damage or both are present before choosing supplies.
Likewise, removing accumulated fluid does not establish that the underlying internal bleed stopped. Continue monitoring circulation and treat each remaining sign.
Edition and evidence
This procedure follows the developer’s release 1.0 text. We have not playtested a universal recovery sequence, and difficulty settings change how quickly the situation develops. Use internal bleeding and thorax muscle health for the next branch of diagnosis. All descriptions concern the game.
