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.

Generally, after pushing the button on the PCA, initial relief of discomfort can begin in as little as five minutes. The PCA medication kicks in quickly, but usually lasts for only a few hours â a much shorter time period than oral pain pills. Oral pain pills dissolve in the stomach and take between 30-45 minutes to start working from the time they are swallowed. Because these pills dissolve slowly in the stomach, they generally work to control pain for 3-4 hours at a time.
