Title: Want more apnea time during Rapid Sequence Intubation? Raise the head of the bed.
題目：在快速序列插管時需要更長窒息時間嗎？將床頭抬高
Author 作者: Haney Mallemat

The supine position during rapid sequence intubation may result in posterior lung atelectasis thereby reducing lung volumes, oxygenation reserve, and ultimately apnea time.
在快速序列插管時，平臥位所造成的肺后葉的肺不張可導致肺容量和肺氧儲備量減低，使窒息時間縮短。
Several studies have shown that elevating the head of the bed by at least 20 degrees or placing a patient in reverse Trendelenberg position (for patients with contra-indications to elevating the head of the bed) during RSI may significantly increase apnea time.
有一些臨床研究顯示，將床頭抬高至少20度或將病人處于反Trendelenburg位（如果不允許將病人頭部抬高）可以在快速序列插管時明顯延長窒息時間。
Elevating the head of the bed may be especially helpful for patients with BMIs >35
抬高床頭尤其會對體質指數（BMI）大于35的病人有效。
