抽象的
本研究旨在测试目前由呼吸师医生给出潜在缺氧患者的建议,规划航空旅行的建议变化,并非证据。进行了一项潜在观察研究,调查英格兰和威尔士的呼吸师医师。六十二个百分之次回应。近三分之二在区综合医院,大学医院的四分之一工作,其余的高等教育(专业)中心或其组合。最常提供建议;大多数剩余部分都在请求或如果有关。评估包括肺活量测定,血液气体水平测量,血氧测量,预测方程和缺氧攻击试验。25%的医生测量血液气体水平推荐在动脉氧张力(PA,O2)<7.3kPa,当PA,O2为7.3-8.0kPa时的50%。使用Spirometry的三分之二推荐氧气当强制呼气量在预测值中的40%的次数<40%时。半推荐氧气当动脉氧饱和度(SA,O2)<90%,33%时,SA时,O 2为90-94%。 Fewer than 10% of district hospital physicians (and none in other hospitals) use predictive equations. More than half of specialists but fewer than 10% of district hospital physicians perform hypoxic challenge tests. The risk of hypoxia at altitude is recognized by most respiratory physicians in England and Wales, but assessment methods and criteria for recommending oxygen vary widely. This suggests that most current advice is not evidence-based. Evidence-based guidelines are required.
