Internal bleeding in Casualties Unknown can be difficult to recognize because blood loss doesn't always come from a visible injury. Without treatment, it can also cause Hemothorax, making breathing increasingly difficult. Fortunately, several medical items can help control the damage.
How to Stop Internal Bleeding in Casualties Unknown
To treat internal bleeding, use an L.R.D. on your thorax with 25 mL of L.R.D. Serum. This immediately reduces the internal bleeding value by 55%. A Makeshift L.R.D. also works, although its reduction is only 25% per 25 mL of serum.
Other treatments can help when an L.R.D. isn't available:
| Treatment | Internal Bleeding Reduction |
|---|---|
| L.R.D. | 55% per 25 mL of serum |
| Makeshift L.R.D. | 25% per 25 mL of serum |
| Procoagulant | 5% every second while active |
| Healing Crystal | 50% upon contact |
| Bunchunk | 25% when consumed |
| Helluce | 20% when consumed |
Procoagulant is particularly useful for sustained treatment because its effect continues reducing internal bleeding over time. The other methods provide immediate percentage reductions.
I'd prioritize an available treatment rather than risk additional injuries searching for a stronger one. Internal bleeding can worsen from further impacts, fractures, and other damage.
Does Internal Bleeding Heal on Its Own?
Yes. Internal bleeding naturally decreases by 0.045 points per second. This makes recovery without medical supplies possible, provided your condition isn't continually worsening.
However, allowing the bleeding to continue can cause blood to accumulate inside the chest. Natural recovery is therefore less desirable when significant blood loss or breathing complications have already developed.
How to Identify Internal Bleeding
The most important warning sign is unexplained blood loss without an obvious external injury. Internal bleeding can develop after serious falls, fractures, head or thorax impacts, and certain traps.
Once the internal bleeding value rises above 5, a status warning can appear if you have the required chip. Your character may also experience nosebleeds or occasionally vomit blood as the condition progresses.
Check your bleeding rate after a severe injury, particularly when visible wounds don't account for the amount of blood being lost.
How to Treat Hemothorax
Hemothorax is a separate complication caused by blood accumulating inside the chest. It progressively reduces oxygen capacity, slows respiration, and increases thorax pain.
To treat Hemothorax, use a Chest Drain on your thorax. Each application reduces the Hemothorax value by 35 points.
Hemothorax can recover naturally at 0.036 points per second, but only after internal bleeding reaches zero. This makes controlling the original bleeding an important first step.
Remember that reducing internal bleeding doesn't immediately eliminate accumulated blood. If breathing problems remain after the bleeding is controlled, Hemothorax may still require treatment.
