During NREM (the phase of sleep in which there is no rapid eye movement) breathing becomes deeper and more regular, but there is also a decrease in the breathing rate, resulting in less air being exchanged overall. This occurs because during NREM sleep the automatic, metabolic system has exclusive control over breathing and the body uses less oxygen and produces less carbon dioxide. Also, during sleep the automatic metabolic system is less responsive to carbon dioxide levels and oxygen levels in the blood. Two things result from these changes in breathing control that occur during sleep. First, there may be a brief cessation or reduction of breathing when falling asleep as the sleeper waxes and wanes between sleep and wakefulness and their differing control mechanisms. Second, once sleep is fully obtained, there is an increase of carbon dioxide and a decrease of oxygen in the blood that persists during NREM. Q4. According to paragraph 3, which of the following may occur just before NREM sleep begins? A. The automatic, metabolic system may increase its dependence on air exanges. B. Breathing can stop for a short times as a person falls asleep. C. An increase in the oxygen level inteh blood can occur as sleep becomes fully obtained. D. The level of carbon dioxide in the blood may drop suddenly. 答案是(C) 但我不知道這題要怎麼去定位@@ 我選了A選項，我還是不知道哪裡錯.... 拜託請版友們幫我解題>< -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 112.105.102.52

既然如此，為何不能推出非during NREM，為Increase
