How-To Evaluate Carbon Monoxide (CO) Poisoning Symptoms?
Posted on 05. Mar, 2011 by Admin in Indoor Air Quality
What are carbon monoxide poisoning symptoms?
Carbon monoxide poisoning symptoms from one time exposure (acute CO poisoning) can range from not feeling any symptoms at all to feeling major symptoms (but not knowing what’s causing them) to death in minutes. These symptoms depend on the level of CO in the air, how long it is breathed, and a person’s level of activity.
Carbon monoxide reacts with hemoglobin (Hb) in red blood cells and forms carboxyhemoglobin (COHb). This is expressed as a percentage of red blood cells carrying carbon monoxide.
| 0-10% | Generally does not cause symptoms but can cause some loss of coordination, tiredness, dizziness, and difficulty focusing in sensitive people |
| 10-20% | Mild frontal headache, nausea, vomiting, dizziness, loss of coordination, difficulty focusing |
| 20-30% | Headache, rapid heartbeat, confusion, lethargy, visual disturbances All levels of exposure from this forward may lead to death as the victim loses motivation and ability to leave the danger zone (even in a fire) |
| 30-40% | Collapse |
| 40-50% | Seizures |
| 50- 60% | Coma |
| 60-70% | Death in under 2 hours |
| 80-90% | Death in under 1 hour |
| 90-100% | Death in minutes |
