CCHS is an uncommon syndrome that is mostly present from the time of birth. It is widely defined as the malfunctioning of automatic control of breathing. The affected individuals have missing or insignificant "ventilatory sensitivity to hypercapnia and hypoxaemia during sleep and wakefulness" (Chen, and Keens 182). This is the reason why patients with CCHS experience progressive hypercapnia and hypoxaemia during sleep (Chen, and Keens 182). Hypoventilation (shallow breathing) is the distinguishing feature of…
