What is the medical term meaning deficient breathing?

The medical term for deficient breathing is hypoventilation. Hypoventilation occurs when the lungs are not adequately ventilated, resulting in a decrease in the amount of oxygen in the blood and an increase in the amount of carbon dioxide. Hypoventilation can be caused by a variety of factors, including:

- Respiratory muscle weakness, such as from neuromuscular disorders

- Airway obstruction, such as from asthma or COPD

- Central nervous system depression, such as from drug overdose

- Chest wall deformity, such as from kyphoscoliosis

- Obesity

Hypoventilation can be a serious condition, and can lead to respiratory failure and even death. Treatment for hypoventilation typically involves the use of mechanical ventilation, which can help to support breathing and improve oxygen levels.
