In short: After a blow to the head, rest — no sport and no work. Call 112 if the person lost consciousness even briefly, vomits more than once, behaves oddly, has a seizure, a limb is weak, balance or vision is affected, or blood or clear fluid comes from the nose or ears. Even if everything seems fine, watch for 24 hours: signs can appear later. All 38 first-aid instructions, based on state-institution and international guidelines (Lithuanian Ministry of Health, NVSC, VVKT, ERC, IFRC), are in the InCaseMap app and work offline — together with a map of hospitals, pharmacies and shelters.

What to do

  1. After a blow to the head – no sport and no work, rest.
  2. Serious injury – ask them not to move the head and neck; if they are lying down, support the head with your hands.
  3. Call 112 if they lost consciousness even briefly, vomit more than once, behave oddly or speak unclearly, have a seizure, a limb is numb or weak, balance is affected, they see double or blurred or light hurts, blood or clear fluid comes from the nose, ears or mouth, or a severe headache does not pass in 2 hours even after painkillers.
  4. Only a bump, a mild headache or nausea – rest and watch.
  5. Even if everything seems fine, watch for 24 hours: signs can appear later.
  6. A suspected concussion must be assessed by a doctor.
