Compressive Asphyxia

The tragic stampede at the Tamilaga Vetri Kazhagam (TVK) rally in Velusamypuram has claimed 41 lives, with doctors attributing most fatalities to compressive asphyxia caused by the crowd crush.

What is Asphyxia?

Asphyxia, or asphyxiation, refers to a condition where the body does not get enough oxygen to function properly. Respiration is the process through which we breathe in oxygen, which is then circulated to all cells via the blood, and carbon dioxide is expelled from the body.

When asphyxia occurs, the body is deprived of oxygen, leading to serious consequences, such as unconsciousness and, in severe cases, death.

About Compressive Asphyxia

Compressive asphyxia is a form of physical asphyxia that happens when external pressure prevents the expansion of the chest, making it impossible to breathe properly. Essentially, the lungs get "crushed," and the person is unable to take in air.

This can occur in various scenarios:

1. Crowd Crush: In tightly packed crowds, people can be pushed or compressed by the weight of others, restricting their ability to expand their chest. This is the most common cause of compressive asphyxia during stampedes or large-scale gatherings.

2. Physical Weight: It can also occur when a heavy object or person presses down on the chest, restricting breathing.

How Compressive Asphyxia Leads to Death

When a person's chest is compressed, it makes breathing impossible, and oxygen intake becomes limited. Without enough oxygen, the body’s vital organs, including the brain, cannot function properly, which can lead to unconsciousness and ultimately death.

In the case of a stampede, the sheer force and pressure from the crowd, coupled with limited mobility, can cause people to become trapped and unable to breathe, leading to asphyxiation.
