A:延迟显像 B:甲状腺素抑制试验显像 C:甲状腺三相显像 D:多体位显像 E:Tc-(V)-DMSA显像

患者送入ICU后，最合适的监护措施是

A:氧输送(D0)监测 B:无创血压监测 C:心排出量监测 D:动脉血氧饱和度监测 E:呼气末二氧化碳分压监测

某女，24岁，气急、咳嗽、发绀，RR30次/分，BP100/60mmHg，动脉血气pH 7.35，PaCO40mmHg，PaO45mmHg，拟“ARDS”。

对该患者采用PSV通气模式机械通气，吸入氧浓度(Fi0)为80%，潮气量10ml/kg，呼吸频率20次/分，30min后，复查动脉血气：pH 7.36，PaCO50mmHg，PaO49mmHg，最合理的调整方案是

A:加用PEEP B:增大FiO至100% C:增大潮气量至14ml/kg D:增加呼吸频率至30次/分 E:减少潮气量至5ml/kg

Across the Deserts

　　The SaharaDesertis the largest desert in the world. It stretches across Africa fromSenegaltoEgypt. TheSaharaDesertis an unfriendly environment. During the day it"s very hot, and at night it’s sometimes very cold. It is also difficult to find water in theSahara.

　　In 2006, Kevin Lin, Ray Zahab, and Charlie Engle decided to do something very difficult. They made the decision to run across the Sahara Desert 4,300 miles (6,920km). It seemed impossible to do, but they wanted to try. The three men liked to test themselves, and this would be a very big test.

　　On the morning of November 2, Kevin, Ray, and Charlie started their trip across theSahara. Every morning they began running at 5:00. At11 a.m. they stopped and rested until 5 p.m. Then they ran again until 9:30 in the evening. Each day they ran about 40 miles (64 km). Every day it was the same thing. They got up and ran. They listened to music on their iPods, and they ran and ran.

　　Kevin, Ray, and Charlie needed to eat a lot of food during their trip. Most people need about 2,000 calories of food each day. Kevin, Ray, and Charlie needed between 6,000 and 9,000 calories every day. That"s a lot of food! They also needed to drink a lot of water.

　　The three men had some problems on their trip, and many times they wanted to quit and go home. It was often very hot (140°F/60°C) during the day, and the heat made them sick. Their legs and feet hurt. Sometimes it was very windy, and they couldn"t see. One time they got lost. But they didn"t quit. After 111 days, Kevin, Ray; and Charlie successfully finished their trip across theSaharaDesert. They hugged each other and put their hands in the water of theRed Sea. Then they ran to a hotel to take a long shower.
