Acute asphyxiation is a condition where the body is deprived of oxygen, which can lead to loss of consciousness, brain injury, or death. Asphyxiation can result from various causes, including drowning, choking, strangulation, seizure, drug overdose, inhaling chemical substances, and more. The symptoms of asphyxiation can include hoarse voice, sore throat, difficulty swallowing, shortness of breath, hyperventilation, worsening of existing asthma, anxiety, poor concentration, headache, blurry or reduced vision, and more. The treatment of asphyxiation depends on the underlying cause and may include immediate intervention to restore oxygen supply, such as CPR, oxygen therapy, or mechanical ventilation. It is important to remain calm and seek emergency medical attention if someone is showing signs of asphyxiation.
