The symptoms associated with high blood carbon dioxide levels include increased blood pressure, rapid pulse, rubor (redness), muscle twitches, headache, chest-pain, confusion, and fatigue. All of these symptoms depend on the severity of case.
Carbon Monoxide robs you of what you need most: oxygen, which is carried to your cells and tissue by the hemoglobin in your blood. If you inhale CO, it quickly bonds with hemoglobin and displaces oxygen. This produces a toxic compound in your blood called carboxyhemoglobin (COHb). Carboxyhemoglobin produces flu-like symptoms, for example: headaches, fatigue, nausea, dizzy spells, confusion, and irritability. Since symptoms are similar to the flu, carbon monoxide poisoning can be misdiagnosed.
