When a ceiling fan falls on someone's head, keep them cool and look for signs of bleeding, swelling, lightheadedness, vomiting, disorientation, severe headache, fainting, impaired vision, or trouble speaking. If you have neck pain, gently apply a cold compress to minimise swelling and refrain from abruptly moving your neck. Head injuries can occasionally result in internal bleeding or a concussion, therefore it's crucial to receive a medical checkup as quickly as possible, even if the patient feels fine. If you experience loss of consciousness, frequent vomiting, seizures, weakness, or unusual tiredness, get emergency medical attention right away.
