Carboxyhemoglobin Formation Secondary to Nitric Oxide Therapy in the Setting of Interstitial Lung Disease and Pulmonary Hypertension
Carbon monoxide (CO) has been widely recognized as an exogenous poison, although endogenous mechanisms for its formation involve heme-oxygenase (HO) isoforms, more specifically HO-1, in the setting of oxidative stress such as acute respiratory distress syndrome, sepsis, trauma, and nitric oxide use have been studied. In patients with refractory hypoxemia,…
