1 Tachycardia may result from pain, apprehension, hypoventilation, or hypovolemia.

2 Methods: The animals achieved hypercapnic acidosis with mechanical hypoventilation before ischemia - reperfusion.

3 Results Apnea hypoventilation index (AHI) decreased and the lowest SaO2 increased and sleep architecture was improved in all patients.

4 While sleep-apnea hypoventilation syndrome(SAHS) is also a kind of common diseases with latent risks.

5 It is commonly caused by chronic alveolar hypoventilation or air way mucus plugging.

6 For their sleep problems alone, snorers spent about $1,000 extra per year, sleep apnea sufferers paid more than $5,000, and those with obesity hypoventilation syndrome exceeded a whopping $15,000.

7 Many neuromuscular diseases caused some sleep disorders such as hypoventilation and chronic respiratory failure.

8 Inadequate ventilation can lead to respiratory acidosis increased, and respirator confrontation occurred, and further exacerbate hypoventilation.

9 Sam, aged six, is just one of around 60 people in Britain with congenital central hypoventilation syndrome (CCHS), which means he often stops breathing.
