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.

Second, today's blood pressure medications last quite a while. In many cases, they only need to be taken once every 24 hours. When you take the medications during those 24 hours should not matter, as long as you take them at the same time every day. Experiencing disturbed sleep when taking blood pressure medications before bedtime is a common issue.
