The driver had been squatting for a long time, replacing a car wheel. Abruptly standing up, he grabs his head and falls unconscious. What should be done?

Объяснение

Standing suddenly after prolonged squatting can briefly reduce blood flow to the brain and cause fainting. Raising the legs helps restore circulation to the upper body, whereas sitting the person up, splashing water, or striking the face does not correct the cause.
