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.

Any antidepressant takes between 10 days and 2 weeks to start to work. YOu may find that you need your dose increased though, so be patient with it. If you dont feel any change after 10 days i would go back to your doctor and tell them so they can increase your dose.
