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.

I was diagnosed with high blood pressure and given Lisinopril. I have to get my bp down before taking my physical for work again and i was not sure how long i should wait before scheduling it. Answers (3) Blood Pressure medicine should start help to lower you blood pressure as soon as you take it. I am on BP medicine and I have a BP monitor so from my experience I took my pressure before my medication and then rechecked it in about a half hour.
