Carbon monoxide poisoning

Carbon monoxide poisoning occurs when an excessive amount of carbon monoxide accumulates in the bloodstream. When the air contains high levels of carbon monoxide, it replaces the oxygen in red blood cells. This can result in severe damage to tissues and potentially lead to death.
Carbon monoxide is a gas that is invisible, odorless, and tasteless. It is produced when fuels like gas, wood, propane, or charcoal are burned. Poorly ventilated appliances and engines can cause the gas to accumulate to dangerous levels. The situation worsens when there is limited airflow in an enclosed space.
If someone is exposed to carbon monoxide, it is crucial to move them to fresh air immediately and seek medical attention. In cases where an individual is in a coma or unable to respond, emergency medical services should be contacted without delay.
Symptoms
The brain and heart are the two organs most impacted by carbon monoxide overdose. With repeated exposure, it’s possible to develop flu-like symptoms without a temperature. Clearer signs of carbon monoxide poisoning include the following:
- Difficulty of breathing
- Confusion
- Weakness
- Headache
- Blurry eyesight
- Drowsiness
- Dizziness
- Nausea
- Loss of muscle coordination
- Fainting
- Vomiting
The neurological system and the brain may experience symptoms following the recovery from carbon monoxide poisoning. Older persons and adults who have lost consciousness from carbon monoxide are at higher risk for these. Some indications include:
- Movement issues
- Loss of memory
- Alterations in personality
Carbon monoxide poisoning poses significant risks, particularly for individuals who are asleep, under the influence of drugs or alcohol. This toxic gas can lead to brain damage or even death without early detection, making it crucial to be aware of the potential dangers.
Causes
Carbon monoxide is produced by many fuel-burning products and engines. Generally, the amount of carbon monoxide emitted is not a cause for concern in well-ventilated areas. However, if these products are used without proper ventilation or in unsafe ways, carbon monoxide poisoning can occur. This can happen if you leave your car running in a closed garage, if your vehicle’s exhaust system is blocked, or if you use kerosene heaters or gas barbecue grills indoors. When carbon monoxide is inhaled, it replaces oxygen in the blood, leading to a lack of oxygen supply to the body’s tissues and organs. In addition to these sources, breathing in smoke during a fire or smoking through a hookah can also result in carbon monoxide poisoning.
Risk factors
For the following people, breathing carbon monoxide can be very risky:
- Babies in the womb. Compared to adult blood cells, fetal blood cells more readily absorb carbon monoxide.
- Infants and children. Children breathe more frequently than adults do.
- Older adults. Brain damage from carbon monoxide poisoning may be more likely to occur in older people.
- Having other health problems. Having anemia, chronic heart disease or breathing problems.
- Other risk factors. Smoking, living in high altitudes, or having jobs with high carbon monoxide levels (e.g., police officers, forklift operators, firefighters, welders, taxi drivers, garage mechanics, or toolbooth attendants) have higher risk of having carbon monoxide poisoning.
Diagnosis
In cases of suspected carbon monoxide poisoning, immediate treatment is typically initiated for individuals brought to the emergency room. A blood test can be performed shortly after exposure to detect the presence of carbon monoxide, although it cannot determine the severity of the poisoning or predict potential long-term health complications. The healthcare provider will determine the most appropriate course of treatment based on factors such as the duration of exposure, the concentration of the gas, and the patient’s overall health condition.
Treatment
It is crucial to immediately seek fresh air if you or someone with you experiences symptoms of carbon monoxide poisoning. If you or the affected person exhibit signs such as headache, dizziness, nausea, shortness of breath, weakness, or confusion, it is imperative to contact emergency medical services for assistance.
Treatment at the hospital for carbon monoxide poisoning may involve the following approaches:
- Administration of pure oxygen: In the emergency room, a common treatment involves delivering pure oxygen to the patient through a mask covering the nose and mouth. This method helps ensure that oxygen reaches the organs and tissues effectively. For individuals who are unable to breathe independently, a ventilator may be utilized to provide mechanical ventilation.
- Hyperbaric oxygen therapy: This treatment option involves breathing pure oxygen within a specialized chamber for a specific duration. The air pressure inside the chamber is increased to 2 to 3 times higher than normal. Hyperbaric oxygen therapy aids in replacing carbon monoxide with oxygen in the bloodstream. It is typically reserved for severe cases of carbon monoxide poisoning, as it helps protect vital organs like the heart and brain from the damaging effects of carbon monoxide. Additionally, pregnant women may undergo this therapy to protect the unborn baby from potential harm caused by carbon monoxide poisoning.
