Introduction
In case of asphyxiation or poisoning, immediately remove the individual from the toxic environment, maintain airway patency, administer emergency first aid, eliminate residual toxins, and record key information. Prompt and proper management can reduce the risk of harm. If severe symptoms such as loss of consciousness, difficulty breathing, or seizures occur, call emergency medical services immediately and seek prompt medical attention. Quickly move the patient to a place with fresh air.

　　In the event of asphyxiation or poisoning, immediately remove the individual from the contaminated environment, ensure airway patency, administer emergency first aid, eliminate residual toxins, and record key information. Prompt and scientific management can reduce the risk of harm. If severe symptoms such as loss of consciousness, difficulty breathing, or seizures occur, call emergency medical services immediately and seek professional medical care.

　　1. Remove from the toxic environment: Quickly move the patient to a safe area with fresh, well-ventilated air, away from the source of the toxin to prevent further inhalation or exposure. Take appropriate personal protective measures during the transfer.

　　2. Maintain airway patency: Loosen the patient’s collar and waistband, clear any foreign objects from the mouth. If the patient is conscious, place them in a lateral (side-lying) position; if unconscious, lay them flat with the head turned to one side to prevent airway blockage by vomit.

　　3. Administer emergency first aid: For choking victims unable to breathe, immediately perform the Heimlich maneuver. If breathing or heartbeat has stopped, begin cardiopulmonary resuscitation (CPR) immediately and continue until emergency responders arrive.

　　4. Remove residual toxins: For skin exposure, rinse the affected area thoroughly with large amounts of running water for at least 15 minutes. For eye exposure, flush the eyes with clean water or saline solution—do not rub the eyes.

　　5. Record critical information: Note the name of the toxin, time and route of exposure, and the patient’s symptoms to assist medical treatment. Never give water or induce vomiting in an unconscious person.

　　Handle the patient gently during transfer to avoid secondary injuries, keep them warm to prevent hypothermia, closely monitor breathing and level of consciousness, and retain samples or containers of the substance involved for medical reference.

Can patients with anxiety disorder experience difficulty breathing or wake up feeling suffocated during sleep?
In general, whether patients with anxiety disorder experience difficulty breathing or awaken from sleep due to suffocation depends on the type of anxiety disorder, severity of the condition, individual differences, and the presence of any comorbid conditions. Avoid drinking strong tea or coffee before bedtime; instead, a small cup of warm milk may help promote relaxation. Keep the bedroom well-ventilated, with suitable temperature and humidity, and choose comfortable pillows and bedding.

Why does anxiety cause a feeling of breathlessness and suffocation, and what should be done about it?
In general, the sensation of breathlessness or suffocation associated with anxiety may be caused by hyperventilation, sympathetic nervous system activation, panic attacks, anxiety disorders, asthma, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve symptoms through breathing regulation, medication, or other methods under a doctor's guidance. In daily life, avoid excessive rumination when alone and engage more in social activities to divert attention.

Is stomach bleeding painful?
In general, whether gastric bleeding causes pain depends on the underlying cause and the progression of the condition. If any discomfort occurs, prompt medical attention is recommended. Once symptoms related to gastric bleeding are identified, regardless of whether pain is present, eating and drinking should be stopped immediately to avoid further burden on the stomach. It is also important to maintain a lateral or supine position to prevent suffocation in case of vomiting blood. The analysis is as follows:

Can gastrointestinal bleeding cause vomiting blood?
In general, whether gastric bleeding leads to hematemesis (vomiting blood) depends on specific factors such as the location of the bleeding, the volume of blood loss, and the bleeding rate. If any discomfort occurs, prompt medical attention is recommended. When symptoms suggestive of gastric bleeding are noticed, regardless of whether hematemesis occurs, immediate medical assistance should be sought. If vomiting blood does occur, the patient should maintain a lateral recumbent position to prevent airway obstruction and potential suffocation caused by vomitus.

Who Are the Five Types of People Who May Be Harmed by Eating Almonds?
Infants' and young children's digestive systems are not yet fully developed. Almonds are relatively hard in texture and contain oils, which can easily cause indigestion after consumption. Inadequate chewing may also lead to coughing, choking, or even the risk of suffocation, posing a threat to health. Certain types of almonds contain small amounts of toxins. Due to their unique physical condition, pregnant women consuming almonds may affect both their own and the fetus's health.

Why is drinking water discouraged in the treatment of heatstroke?
In general, drinking water is avoided during the treatment of heatstroke because it may cause choking and suffocation, worsen electrolyte imbalances, increase the burden on the heart, interfere with gastrointestinal function, or lead to water intoxication. During heatstroke treatment, it is essential to strictly follow the guidance of medical staff and not to give water to the patient without authorization. If fluid and electrolyte replacement is necessary, it should be done under professional supervision.

Why is drinking water prohibited for heatstroke?
Heatstroke patients often experience impaired consciousness and weakened or lost swallowing function. In such cases, drinking water easily causes liquid to enter the trachea, triggering severe coughing, and in serious cases, leading to airway obstruction and a risk of suffocation; therefore, water intake should be prohibited. During high fever, the heart is already in a state of excessive workload. Drinking water rapidly increases blood volume, further burdening the heart and potentially inducing arrhythmia or heart failure.
