Clinical SME Oversight
This analysis was developed by Penny Pratt, RN, CSPI, providing Expert-in-the-Loop review to support clinical accuracy, patient safety, and responsible healthcare communication.
Carbon monoxide (CO) exposure remains a significant contributor to unintentional poisoning-related morbidity and mortality, in part because its early presentation closely mimics benign viral illness. For this MedReport Foundation article, I applied my expertise as a Certified Specialist in Poison Information (CSPI) to examine the pathophysiology of CO poisoning, including impaired oxygen delivery, cellular hypoxia, neurologic injury, and cardiovascular compromise.
By integrating CDC surveillance data with established toxicological and emergency response principles, I developed an evidence-based resource that clarifies early recognition, outlines time-sensitive intervention priorities, and reinforces primary prevention strategies. The result strengthens risk communication in settings where delayed recognition can result in irreversible harm.
