Carbon Monoxide Poisoning

Every year in the United States, accidental carbon monoxide poisoning tragically claims the lives of over 400 individuals. Additionally, more than 100,000 people end up in emergency rooms due to exposure to this deadly gas.

Recognizing the Symptoms and Causes of Carbon Monoxide Poisoning

Early Signs and Symptoms

Carbon monoxide poisoning can be subtle at first. Early symptoms include:

• Mild headache
• Nausea
• Shortness of breath

Moderate Exposure Symptoms

As exposure continues, the symptoms can become more severe:

• Chest pain
• Dizziness and weakness
• Loss of consciousness (fainting)
• Loss of muscle coordination
• Mental confusion
• Severe headache
• Upset stomach, nausea, and vomiting

If you notice any of these warning signs, it’s crucial to leave the environment immediately and contact 911 or local emergency services. Do not stay inside to make the call. If you can’t safely leave, open a window or door and stay close to it while seeking help.

Delayed Symptoms

Even low levels of carbon monoxide can cause delayed symptoms that might not appear right away but are still dangerous. Prolonged exposure to this toxic gas can lead to severe health issues, so if you suspect carbon monoxide exposure, contact emergency services immediately.

Causes of Carbon Monoxide Poisoning

Carbon monoxide poisoning happens when you inhale the fumes from burning fuel. Normally, our lungs transfer oxygen into our bloodstream, but carbon monoxide hinders this process. Many everyday appliances and vehicles emit carbon monoxide when burning fuel, but they are safe if used and maintained correctly. Problems arise when these appliances operate without proper ventilation. For example:

• Leaving a car or truck running in an enclosed space, like a garage.
• A vehicle with a blocked exhaust system, potentially due to snow in the tailpipe.
• Using a kerosene heater or a gas barbecue grill indoors.

The Effects of Carbon Monoxide on the Body

Carbon monoxide interferes with the oxygen-carrying function of red blood cells, leading to oxygen deprivation in vital organs. High levels of carbon monoxide exposure can quickly replace oxygen in your bloodstream, causing severe health issues, including loss of consciousness and suffocation within minutes.

Who is at Risk?

Everyone is at risk of carbon monoxide poisoning, but certain groups are more vulnerable, especially in winter when heating systems are in use more frequently. High-risk groups include:

• Developing fetuses
• Infants
• Adults over age 65
• People living at high altitudes
• Individuals with chronic heart disease, anemia, or respiratory issues
• Tobacco smokers
• Pets and small animals, which may show symptoms before humans
• Occupations like firefighters, mechanics, drivers, and welders

Complications of Carbon Monoxide Poisoning

Carbon monoxide poisoning is life-threatening, and even a few minutes of exposure can be fatal. Prompt treatment can reverse its effects, but lingering complications might affect your health, including breathing difficulties, memory loss, heart abnormalities, and, in pregnant individuals, the risk of miscarriage or abnormal fetal development.

Diagnosing and Treating Carbon Monoxide Poisoning

Diagnosis

Healthcare providers diagnose carbon monoxide poisoning with blood tests to assess CO levels. They might also monitor your heart rate and oxygen levels using a finger oximeter. A thorough medical history and details about CO exposure are crucial for diagnosis.

Treatment

The primary treatment involves inhaling pure oxygen, administered through a mask, to help eliminate carbon monoxide from the body. If you suspect exposure, contact emergency services immediately and move to a well-ventilated area to await help.

Home Treatment

Attempting to treat carbon monoxide poisoning at home is not advisable. If you suspect exposure, contact emergency services right away. Healthcare providers can monitor your oxygen levels to prevent long-term complications. Ensure your home has proper ventilation and working appliances, and install a carbon monoxide detector to provide early warnings of CO leaks.

Preventing Carbon Monoxide Poisoning

Annual Inspections

Each heating season, hire a professional to inspect fuel-burning appliances in your home, including oil and gas furnaces, gas water heaters, gas ranges, and ovens, gas dryers, gas or kerosene space heaters, fireplaces, wood stoves, and flues and chimneys.

Appliance Safety

For fuel-burning appliances, follow these precautions:

• Choose appliances that vent fumes outside and ensure they are properly installed and maintained.
• Purchase gas equipment with national testing agency seals.
• Follow instructions for fuel-burning appliances and use the right fuel for unvented gas or kerosene space heaters while ensuring proper ventilation.

Carbon Monoxide Detectors

Install a battery-operated or battery backup carbon monoxide detector in your home. Regularly test the detector, change its batteries, and place it where you can hear the alarm.

Reducing Risk at Work

For occupations involving potential CO exposure, wear safety equipment and ensure adequate ventilation. If you suspect CO exposure, leave the area immediately and call emergency services.

Outlook and Prognosis

Carbon monoxide poisoning can be fatal, especially with high concentrations of CO. Quick action is essential if you suspect exposure. The long-term outlook depends on the duration and level of CO exposure, with the potential for permanent damage to the brain and heart.

Living With Carbon Monoxide Poisoning

Self-Care

Install a carbon monoxide detector in your home. If the alarm sounds, exit the area, call 911, and wait for emergency responders to ensure it’s safe to reenter.

Emergency Room Visits

If you suspect carbon monoxide exposure, move to fresh air and call for help immediately.

Questions for Your Provider

If you receive treatment for carbon monoxide poisoning, ask about the potential for permanent damage, the need for follow-up care, preventive measures, long-term treatment, and potential effects on your reproductive system or fertility.

Staying informed and taking preventive measures can help protect you and your loved ones from the dangers of carbon monoxide poisoning.
