A medical emergency is a situation in which the health of a person is at high risk of deteriorating rapidly without immediate medical attention.
For example, chest pains, increasing difficulty in breathing, impaired consciousness and any of the signs of a stroke (facial weakness, inability to lift a limb or slurred speech) constitute an emergency.
In a medical emergency you can access urgent paramedical help by calling 999 (or 911)
NHS 111 is an NHS telephone number to call when you need medical help fast, but if it is a life threatening emergency, you should call 999.
