Carbon monoxide poisoning is the most common form of asphyxia. The patient should be ventilated immediately, cut off the source of the poisoned substance, move the patient away from the place of poisoning and at the same time rush to the hospital for treatment; for those whose heartbeat and breathing have stopped, cardiopulmonary resuscitation should be performed immediately and then immediately sent to the hospital for resuscitation. Remember to send and rescue at the same time, without interruption.
