Too much carbon dioxide will not be poisoned

Carbon dioxide is non-toxic, but it can be fatal, and the affinity with hemoglobin is 200 times higher than that of oxygen and hemoglobin (about 250 times to be exact), not carbon dioxide is carbon monoxide. The diffusion coefficient of oxygen is smaller than that of carbon dioxide because of the low solubility of oxygen. In the body, oxygen and carbon dioxide are mostly transported in a combined form, and carbon dioxide is transported in two ways in the body, carbamoylhemoglobin and bicarbonate ions.

Excessive inhalation or impaired excretion of carbon dioxide can lead to a primary increase in plasma carbonic acid concentration, resulting in respiratory acidosis. The decrease in hemoglobin affinity for oxygen due to excess carbon dioxide is also due to this reason, because the decrease in blood pH leads to a decrease in p50 and the oxygen dissociation curve shifts to the right.

Not poisoning, but death.

Carbon dioxide, which reduces the binding capacity of hemoglobin and oxygen, because we know that the affinity of carbon dioxide and hemoglobin is two hundred times higher than that of oxygen and hemoglobin!

When too much carbon dioxide is inhaled, hemoglobin cannot carry oxygen, and the person dies.

No, carbon dioxide is not toxic, it just doesn't supply breathing.

Yes, it can lead to carbon dioxide poisoning and eventually death.

Carbon monoxide, commonly known as coal gas, is a colorless, odorless, odorless, lighter than air. Carbon monoxide poisoning is mainly due to the combination of carbon monoxide in the air and hemoglobin of red blood cells that transports oxygen to produce carboxyhemoglobin, which makes the blood lose the ability to carry oxygen, causing people to suffer from hypoxia and produce various poisoning symptoms, such as headache, nausea and vomiting, weakness of limbs, etc. When the concentration of carbon monoxide in the blood reaches a certain level, it can cause suffocation and death.

How can I prevent carbon monoxide poisoning?

Be vigilant about some stoves connected to a kang or a warm wall, do not seal the stove before going to bed, and let the fire burn out to avoid poisoning.

The harm of carbon monoxide poisoning is mainly divided into the harm to patients and the impact on family members, there will be a series of complications after severe carbon monoxide poisoning, even if you actively accept **, there will be many sequelae, seriously affecting the health of patients.

1. Harm to patients.

Severe carbon monoxide poisoning can have a range of complications, such as pulmonary fever, cardiac lesions, aspiration pneumonia, or pulmonary edema. Even if you accept **, you may also have dementia, poor comprehension, memory loss, or limb paralysis and other sequelae, which will have a serious impact on the patient, and may even have long-term depression.

2. Impact on family members.

Severe carbon monoxide poisoning can also cause a series of sequelae, the most common of which is neurological sequelae, which will not only affect the quality of life of the family, but also increase the financial burden of the family. Because you need nursing care for a long time, it can also have a serious impact on your family.

Carbon monoxide poisoning refers to gas poisoning, which usually occurs when carbon-containing substances are not completely burned and ventilation is poor. Carbon monoxide has a hundred times more affinity for hemoglobin than oxygen for hemoglobin.

Carbon monoxide poisoning mainly causes hypoxia, especially in the central nervous system, which can lead to widespread damage to brain tissue. Severe carbon monoxide poisoning can lead to coma and even death, and patients who are in a coma can wake up and turn the corner after resuscitation.

However, some patients have mental and neurological symptoms immediately after waking up, and some patients have mental and neurological symptoms after being awake for days, weeks or even two months, among which some patients show dementia and stiffness, and at the same time have mental retardation, sluggish expression, incompetence in previous work, and even inability to take care of themselves, incontinence, and muscle rigidity.

Accelerated respiration can mobilize the alveoli that were not involved in respiration to increase the breathing area, improve the diffusion of oxygen, and increase the oxygen saturation of the arteries. Allows more fresh air to enter the alveoli, increases the partial pressure of oxygen, and decreases the partial pressure of carbon dioxide; The increase in the amplitude of thoracic motion, the increase of intrathoracic negative pressure, the increase of blood return to the heart, and the increase of cardiac output and pulmonary blood flow are conducive to oxygen uptake and transport.

Carbon monoxide is very easy to combine with hemoglobin to form carboxyhemoglobin, which makes hemoglobin lose its oxygen-carrying ability and effect, causing tissue suffocation. It has a toxic effect on tissue cells throughout the body, especially on the cerebral cortex.

No. In terms of gas properties, carbon dioxide gas is non-toxic, but if the concentration in the air is too high, it will cause suffocation, because the concentration of carbonic acid in the blood increases, the acidity increases, and acidosis occurs. <
