Casualties: Unknown Shrapnel and Defibrillator Guide

The common injury set

The official description makes wound care, infection and blood loss central survival tasks. Open the health panel with R or the heart button and identify the problem before choosing an item. This page separates bleeding limbs, lodged shrapnel, infection and dangerous heart rhythms; internal bleeding has its own treatment guide. Sources: Steam and the release tutorials.

How do I stop a limb bleeding?

1. Pick up a dressing and open the health panel.
2. Right-click and drag the dressing over the damaged limb.
3. Left-click and drag around the limb to perform the wrapping interaction.
4. Recheck the limb and blood loss before moving to another injury.

The first three steps are explicit in release Basic Training and the bandaging prompt. A dressing slows bleeding and helps skin healing and fracture stabilization, but does not restore muscle health. Do not treat it as a replacement for the separate internal-bleeding treatments.

Shrapnel

Choose Remove shrapnel in the health panel to begin manual removal. Pull the fragments out slowly: the release minigame warns that moving too fast hurts. Tweezers bypass the speed limit, but the interface also explicitly permits trying removal by hand. See the release removal and minigame text.

What do I do after extracting a fragment?

Inspect the limb again and treat any remaining bleeding with the dressing interaction above. This is a follow-up check rather than a claim that extraction always causes a new wound. Avoid equating completion of the removal minigame with treatment of every condition on that limb.

Infection

Apply antiseptic to the infected site through the health panel. Release Basic Training tells you to repeat treatment every few minutes and use the arrow on the infection icon to see whether the infection is progressing or regressing. Sterilized dressing also counteracts infection. These instructions appear in the release text and the older medical guide.

Splints and limb support

A splint helps fractures and dislocations heal. Putting one on a functional limb still immobilizes it, reducing your capabilities, so check the affected limb before applying it. This constraint is explicit in the release splint description.

Defibrillators and asystole

How do I use the manual defibrillator?

1. Inspect the ECG and the arrhythmia condition in the health panel.
2. Use the manual defibrillator on the chest or upper torso.
3. Match its power to fibrillation progression: low when arrhythmia has just started, higher when the heart is close to stopping.
4. Use the ECG and displayed power estimate to refine that setting.
5. Set power, charge, then shock; repeat as needed until arrhythmia clears.

The release First Aid Course supplies this sequence, independently matching the earlier medical guide. A closer power match improves the chance of success, and higher INT helps operation. The device can still fail, so the instructions do not promise a successful first shock.

Is a stopped heart treated the same way?

The release course distinguishes fibrillation from a heart that has stopped. It describes an autopump maintaining consciousness and epinephrine, found in combat pens, as a possible restart treatment. The release drug description qualifies this as a low chance of success and warns that going over 40 mL causes fibrillation. Do not interpret the training exercise as a guaranteed revival or that warning as a recommended dose. The older medical guide records that since demo 6.1, defibrillators do not always fix asystole. Sources: release First Aid and historical cardiac-arrest guidance.

Evidence limits

The actionable interactions above come from release locale 1.0.1 rather than inferred patch history. Demo 6.0 introduced the two-defibrillator system, and the 6.1 asystole change is historical context. No universal revival guarantee, drug dose or hands-on treatment test is claimed.
