1. Symptoms:

Mild: headache, dizziness, palpitation, nausea, and vomiting.

Moderate: flushing complexion, cherry red lips, hyperhidrosis, irritability, and coma gradually.

Severe: Unconsciousness, dementia, incontinence, cold extremities, dilated pupils, decreased blood pressure, weak or stopped breathing, possibly increased body temperature, stiffness or paralysis of limbs, myocardial damage or arrhythmia, disappearance of various reflexes, Or into a pathological reflex.

2. Diagnosis:

The diagnosis can be confirmed based on the medical history and symptoms. The carbon monoxide inspection method:

①The blood is cherry red;

②Take a drop of blood and add it to a glass of water, which turns reddish (yellow for normal people);

③ Take the blood and add 10ml of water, add a few drops of 10% sodium hydroxide, it turns pink (normal people's blood turns green).

Initial dizziness, headache, tinnitus, vertigo, weakness of limbs and general malaise. The symptoms gradually worsen with nausea, vomiting, chest tightness, followed by lethargy, coma, shortness of breath, blood pressure drop, and even death. The severity of symptoms is related to carboxyhemoglobin. It is more or less related. When the blood contains 10%-20% carboxyhemoglobin, headache, nausea, weakness, vomiting, dizziness, confusion, tremor, and even collapse occur when the blood content reaches 30%-50%; up to 50% ~60% have coma and convulsions; up to 70%~80%, the respiratory center will be paralyzed, and the heartbeat will stop. Because the carboxyhemoglobin is red, the patient has no bruising, and the skin and lips are cherry red.
