Signs of Asphyxiation by Strangulation
Asphyxiation is a form of suffocation caused by a lack of oxygen in the body. Strangulation is a type of asphyxiation caused by external pressure on the neck that obstructs the flow of air. It can be caused by compression of the trachea or by constricting the carotid arteries, both of which are located in the neck. Strangulation can be fatal if not treated quickly, and it is important to be aware of the signs and symptoms.
Tracheal Compression
When the trachea is compressed, it restricts the airflow into the lungs. This can lead to a rapid decrease in oxygen levels in the body, leading to asphyxiation. Signs of tracheal compression include difficulty breathing, gasping for air, and a hoarse or raspy voice.
Carotid Artery Compression
Compression of the carotid arteries can also cause asphyxiation due to a decrease in oxygen levels. Signs of carotid artery compression include a decrease in blood pressure, lightheadedness, and loss of consciousness.
Other Signs and Symptoms
Other signs and symptoms of asphyxiation by strangulation include dizziness, nausea, chest pain, blurred vision, and confusion. Additionally, the skin may become pale and the lips and fingernails may appear blue due to a lack of oxygen.
If you suspect that someone is being strangled, it is important to act quickly to prevent further damage or death. Call 911 or your local emergency services immediately and provide as much information as possible about the situation.
