心里轻松了许多!
后来补充:
我查到一篇论文,讲的和你说的一样:
FEV1/FVC, FEV3/FVC, and 1 – FEV3/FVC characterize expiratory obstruction
well. In contrast, FEF25–75 measurements can be misleading and can cause an
unacceptably large number of probable false-negative results and probable
false-positive results.

做一次,然后吸一种药,然后再测一次,所有结果都无改变。
只有一个结果不正常,FEF,forced expiratory flow只有70%多。
其余各正常结果是:
FVC 157%
FEV1 156%
FEV1/FVC 99%
PEFR 91%
计算机报告自动生成的解释是,possible early obstructive pulmonary impairment
。(看起来很吓人。。。我大致google了一下,似乎多是有毒物质导致的肺损坏)
医生给开了抗生素和一种镇咳的药,说如果好了就不用X光了,如果不好再回去拍片。
觉得心理不踏实呢。。。偶的工作不接触任何有毒物质,无家庭肺病史,从不吸烟。。。最近一次
咳嗽也是04年了,感冒后,冬天,半个多月,痰浓,吃了阵子抗生素好的。这种吹气测试过去从
没做过。
哪位达人提供一下看法?有些怕怕。感激不尽!! |

i wouldn't worry too much about, your FEV1/FVC is 99%, so i don't think
there is any obstructive issue here, FEV 25-75% is a fine parameter looking
into patients with obstructive disease how severe there small airway
obstruction is, it's calculated from a formula that takes into account of
your height and age, i don't remember exactly how the formula is, but i
think depends on whether you are white, hispanic, or black t |
