You should treat a person who is conscious but suffering from circulatory shock calmly and gently as stress can worsen the condition. Make sure that he or she is warm, does not bleed and can breathe unrestricted.
Do not give the person any form of food or drink as it may end up blocking the airways if the person vomits or faints.
A person who has been severely injured and lost a lot of blood may suffer from a life-threatening condition called circulatory shock. Circulatory shock means that blood circulation is so poor that it can lead to oxygen deficiency and cell damage.
A person with circulatory shock has a rapid pulse, greyish and clammy skin and is cold, thirsty, worried and restless.
