Mechanical asphyxia is a type of asphyxiation caused by external forces or mechanical obstruction of the airways. Common causes of mechanical asphyxia include strangulation, chest compression, and drowning. This type of asphyxia is usually caused by the intentional actions of another person, although it can also occur accidentally.
Strangulation
Strangulation is the most common cause of mechanical asphyxia. It occurs when a person's neck or upper airways are constricted by a ligature, belt, or hands. The pressure compresses the trachea, preventing air from entering the lungs. This type of asphyxiation can happen very quickly, leading to unconsciousness and death.
Chest Compression
Chest compression is another form of mechanical asphyxia. This occurs when someone is pinned down or pressed against a hard surface, such as the ground. The pressure of the surface on the chest prevents the person from taking in a full breath. This can cause a person to experience difficulty breathing, dizziness, and eventually unconsciousness.
Drowning
Drowning is another form of mechanical asphyxia. This occurs when a person is submerged in water and is unable to breathe. The water can fill up the lungs, preventing oxygen from entering the body. Drowning can happen quickly, leading to unconsciousness and death.
Conclusion
Mechanical asphyxia is a type of asphyxiation caused by external forces or mechanical obstruction of the airways. Common causes of mechanical asphyxia include strangulation, chest compression, and drowning. It is important to be aware of the risks associated with each of these causes in order to prevent and treat mechanical asphyxia.
