This type of atelectasis may also result from physical trauma to the lungs like during car accidents or stabbing incidents.

Intermediate-acting insulin reaches the bloodstream in two to four hours, peaks in four to 12 hours, and works for up to 18 hours. Long-acting insulin takes six to 10 hours to start working, but it lasts for 20-24 hours. Many people with diabetes may use different types of insulins to get the optimal effect on their blood sugar levels.
