Hypoventilation (also known as respiratory depression) occurs when ventilation is inadequate (hypo meaning "below") to perform needed respiratory gas exchange. [1] By definition it causes an increased concentration of carbon dioxide ( hypercapnia ) and respiratory acidosis .
Central hypoventilation syndrome (CHS) is a sleep-related breathing disorder that causes ineffective breathing, apnea, or respiratory arrest during sleep (and during wakefulness in severe cases). CHS can either be congenital (CCHS) or acquired (ACHS) later in life.
Central nervous system disorders, such as stroke and tumors, may cause hypoventilation. Drugs may decrease respiratory effort as well, such as opioids, sedative-hypnotics, and alcohol. These lower respiratory drive by blunting the response of the respiratory center of the brain to hypercapnia. [10]
Another possible cause of chest pain that you can reproduce easily is costochondritis, which happens when the cartilage around your ribs becomes inflamed, the Mayo Clinic says. And it most often ...
Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. This failure in ventilation may be caused by depression of the central respiratory center by cerebral disease or drugs, inability to ventilate adequately due to neuromuscular disease (e.g., myasthenia gravis, amyotrophic lateral sclerosis, Guillain–Barré syndrome, muscular dystrophy), or airway obstruction ...
The underlying cause is unclear. Some believe the pain may be from the chest wall or irritation of an intercostal nerve. [1] [2] Risk factors include psychological stress. [2] The pain is not due to the heart. Diagnosis is based on the symptoms. Other conditions that may produce similar symptoms include angina, pericarditis, pleurisy, and chest ...
Fig. 6: Shallow breathing using rib muscles. Shallow breathing, thoracic breathing, costal breathing or chest breathing [1] is the drawing of minimal breath into the lungs, usually by drawing air into the chest area using the intercostal muscles rather than throughout the lungs via the diaphragm.
Surgery is generally a last resort in hypopnea treatment, but is a site-specific option for the upper airway. Depending on the cause of obstruction, surgery may focus on the soft palate, the uvula, tonsils, adenoids or the tongue. There are also more complex surgeries that are performed with the adjustment of other bone structures - the mouth ...
