Overview
Methemoglobinemia will present with different signs and symptoms depending on the methemoglobin levels in the blood.
History and Symptoms
- Depending on the levels of MetHb in the blood we can observe different symptoms as follows: Patients with MetHb levels of up to 15% will present with skin and blood color (chocolate-brown) changes. Patients with MetHb levels above 15% will present with hypoxia and MetHb levels above 70% can lead to death.[1] [2]
- Cyanosis that is unresponsive to oxygen treatment is the main physical finding in people with methemoglobinemia, along with that the patient can present with dizziness, nausea and shortness of breath.
