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.

If it is going to help, the benefit of depo-medrol should be apparent in 3 to 5 days. I think depo-medrol shots work quickly, usually within 24 hours at most & inmediately for some people. i've only have one mild shot of Depo & had some relief within 12 hours but due to an ongoing staph infection still had drainage.
