How Much Blood Can a Person Lose in an Accident? Why Blood Banks Are Critical 

When an accident occurs the most major threat isn’t always the injury itself; it can sometimes be the loss of blood. An individual who has lost a significant amount of blood in a short period of time will soon suffer from shock which could cause the failure of major organs or death. It is important to know how much blood can be lost from an accident and the reasons why having safe blood available immediately can save lives. At Abirami Hospital, the Blood Bank at Coimbatore ensures quick access and safe availability of cross matched blood, designates the blood bank as a necessary service for use in accidents, emergency procedures, and ongoing care of seriously ill patients.

How Much Blood in the Human Body

Normal blood volume in adults ranges from 4.5 to 5.5l depending on age, gender, build and state of health. Blood performs several essential functions:

• Carries oxygen to all body organs.
• Provides nutrients to all parts of the body
• Helps fight infections
• Maintains body temperature
• Assists with blood clotting following damage.

Even an amount of blood loss that may be considered modest can alter the physiology of the body.

What is a dangerous amount of blood loss?

Doctors have defined various stages of blood loss.

Minor Blood Loss (Up to 15%)

A person can bleed 500–750 ml and have minimal symptoms. The system generally compensates quite well, although the person may become mildly dizzy.

Moderate Blood Loss (15%–30%)

When blood loss reaches 750 to 1,500 ml, symptoms become noticeable:

• Rapid heartbeat
• Fast breathing
• Weakness
• Dizziness
• Pale skin
• Increased thirst

Needs Emergency Treatment.

Severe Blood Loss (30%–40%)

Losing 1.5 to 2 litres of blood becomes life-threatening. The patient may experience:

• Confusion
• Very low blood pressure
• Cold and clammy skin
• Difficulty breathing
• Reduced urine output

Emergency blood transfusion is also common.

Critical Blood Loss (More Than 40%)

Depletion of greater than 2 litres of blood rapidly leads to death if not cared for by emergency, surgical and blood replacement procedures.

Why Accidents Cause Massive Blood Loss

Road traffic accidents are one of the most common causes of major haemorrhage. Haemorrhage can occur from:

• Deep cuts and wounds
• Internal bleeding
• Bone fractures
• Head injuries
• Chest injuries
• Abdominal trauma

In some cases bleeding cannot be identified externally and an urgent hospital assessment is crucial.

Why Every Minute Matters

If the body loses blood acutely, many of the organs will no longer be perfused appropriately. This is hemorrhagic shock. Without quick treatment:

• Brain damage can occur
• Kidneys may fail
• Heart function becomes unstable
• Many organs may fail.

This is the reason emergency departements always need access to safe blood immediately.

The Importance of a Blood Bank During Emergencies

An adequately resourced blood bank will be able to provide compatible blood to their patients in a timely fashion. A reliable blood bank provides:

• Whole blood
• Packed red blood cells
• Plasma
• Platelets
• Emergency blood transfusion support
• Blood compatibility testing

These services become critically important during trauma management, emergency procedures, labor and delivery complications and serious illness.

Use of Blood Transfusion in Case of Accident Victims

Yes. Blood transfusions are a potentially life saving occurence when a patient has lost large quantities of blood. Doctors may transfuse:

• Red cells to order in the wake of any restoration of oxygenation once the transfusion with red cells has been completed
• Plasma to improve clotting
• Platelets to control bleeding
• Whole blood in particular emergency conditions

But the type of blood group will vary with the patient because of their condition and blood loss.

The Role of Blood Donors

Blood cannot be artificially produced in laboratories. The hospitals rely on voluntary blood donors to keep the blood stock sufficient. One donation can save many more patients because blood can be separated into blood components. Benefits of voluntary blood donation include:

• Saving accident victims
• Helping cancer patients
• Supporting major surgeries
• Help in the delivery of the mothers.
• Managing diseases of the blood.

Tips During an Accident Involving Heavy Bleeding

If someone is bleeding heavily:

• Call emergency medical services, if possible, without delay.
• Use a clean cloth and press down firmly.
• Try to keep the injured person lying down.
• Don‘t take out objects which are very well hidden.
• Raise the injured limb if there is no fracture.
• Immediately head for the nearest emergency hospital.

Never treat at home a person who is bleeding heavily.

Conclusion

Severe bleeding due to accidents can result in hazardous blood loss within a matter of seconds, so first aid is vital.
