Congenital central hypoventilation syndrome - Global Genes

WebObesity hypoventilation syndrome (OHS), or Pickwickian syndrome, is a breathing disorder that affects some people who have obesity. The condition results in too much carbon dioxide in your blood and not enough oxygen. This occurs due to hypoventilation, which means breathing at an abnormally slow rate. OHS can cause life-threatening health issues. WebThus, despite deliberate global hypoventilation, these functioning units may sustain ongoing high tidal volume injury, made worse by their own local respiratory alkalosis.23Inspired carbon dioxide guarantees that all lung regions, at a minimum, will always see a Pco 2 equivalent to the inspired value.

WebThe alveolar hypoventilation leads to a rate of excretion of CO 2 that is less than its metabolic production. This net gain in CO 2 causes a rise in the PaCO 2. The lungs may be subject to diffuse hypoventilation (global alveolar hypoventilation), or only parts of the lungs may be involved (regional alveolar hypoventilation).
