Emergency knowledge to know

• Clammy skin, weak and rapid pulse, anxiety, nausea, thirst and faintness are signs of shock - organs aren't getting enough blood or oxygen.

• An allergic reaction may cause anaphylactic shock, a sudden drop in blood pressure and trouble breathing. Anaphylaxis can occur minutes after exposure and severe cases can lead to death within half an hour.
