There are two known types of atelectasis. The first type is called acute atelectasis which usually results from surgery involving the opening of the chest cavity or the abdominal area. This type of atelectasis may also result from physical trauma to the lungs like during car accidents or stabbing incidents.

The 25 mcg is a relatively small amount, probably a starter dosage. With T4 meds it takes 4 weeks to build up to 90% of its total effect on blood levels. Symptoms tend to lag somewhat changes in blood levels. Also, the lag time depends on length of time you were hypo and the severity. So a lot of patience is necessary for hypo patients.
