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.

Usually antibiotics start working in 24-36 hours.However, when the infection is in atooth or jaw (bone) it takes longer merely because the blood supply is not as good in that kind of tissue .Warm compresses help to increase the blood flow into the area and carry the meds to the area.Karen James.
