Open R and identify what is failing before spending supplies. The developer’s course explains that keeping the brain alive requires enough flowing, oxygenated blood. A stable-looking limb does not prove the whole circulation system is safe.
Match the sign to the problem
| What you see | First place to investigate |
|---|---|
| A bleeding limb | Dress that limb and inspect its bleeding value |
| Blood falling without a clear external wound | Internal-bleeding moodle and total bleeding rate |
| Arrhythmia warning | ECG, heart rate and circulation; defibrillator interaction |
| Breathing or SpO2 falling | Thorax muscle health and hemothorax warning |
| An infection arrow rising | The infected limb and antiseptic treatment |
These are game systems, not real-world treatment instructions.
Use the right interaction
A health-panel item should be dragged onto its intended body part. Dressings wrap around a limb; defibrillators and chest drains belong on the chest. Applying a whole supply to the wrong place can waste it, as the tutorial’s failure lines explicitly demonstrate.
Recheck after treatment
Look again at the rate or warning you were trying to change. Reducing pain does not establish that bleeding stopped. Resetting fibrillation does not replace lost blood. A tourniquet stops flow temporarily but does not heal the wound.
The First Aid course unlocks at layer 2. Use bleeding treatment, internal bleeding or hemothorax for the matching procedure rather than stacking unrelated items.
