While the presence of Islam in West Africa dates back to eighth century, the spread of the faith in regions that are now the modern states of Senegal, Gambia, Guinea, Burkina Faso, Niger, Mali and Nigeria, was in actuality, a gradual and complex process.
Hypoventilation is a condition that arises when air entering the alveoli, small air sacs in the lungs that are the site of respiratory gas exchange, is reduced. This causes levels of oxygen to decrease and the levels of carbon dioxide to increase.
Definition - What does Hypoventilation mean? Hypoventilation occurs when the body's lungs cannot absorb enough oxygen and carbon dioxide then builds up in the blood stream. Hypoventilation is caused when the amount of air entering, or processed by, the pulmonary alveoli in the lungs is reduced. The condition is usually diagnosed by measuring the patient's arterial blood gases (ABG) to detect high levels of carbon dioxide.
