Abstract:
Clinically significant methemoglobinemia is rare and difficult to diagnose when other causes of cyanosis are likely. We report a patient in whom unstable angina pectoris and chronic obstructive pulmonary disease were assumed to be responsible for preoperative cyanosis. The use of cardiopulmonary bypass for aortocoronary grafting enabled the clinical diagnosis of methemoglobinemia to be made.

Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...
Pneumothorax-I
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
