Elevated carbon dioxide (CO2) levels in the
blood, termed hypercapnia, can cause symptoms like shortness of breath,
confusion, headaches, fatigue, flushing, and a faster heart rate. Conversely,
reduced CO2 levels, or hypocapnia, often due to hyperventilation, may lead to
dizziness, lightheadedness, confusion, muscle twitching, nausea, and chest
discomfort. Healthcare providers utilize a CO2 blood test for diagnosis and
monitoring. Treatment depends on the specific condition, including respiratory
disorders or metabolic imbalances, and may involve medications, oxygen therapy,
or respiratory interventions to restore CO2 balance.
