what is mild dependent atelectasis

Atelectasis is the condition wherein the lungs get collapsed due to various reasons and the lungs are unable to perform the function of exchange of gases in an efficient manner. Atelectasis is also known as a collapsed lung or partially collapsed lung. In the group without atelectasis, we found a SatO2/FiO2 ratio of 357 (230 to 438), compared to 411 (331 to 453) in those with small atelectasis (p=0.07) and to 182 (113 to 359) in those with large atelectasis (p=0.17). When lying down, you may be asked to ensure that your head is below the level of your heart. Incidence doesn't increase in patient with increased age, The incidence of atelectasis in patients who have recently undergone general anesthesia is as high as 90%, It is commonly observed as a complication in, Atelectasis is less commonly seen in patients with conditions like, Cephalad displacement of the diaphragm in, pathophysiologic mechanism (e.g., compressive atelectasis), the amount of lung involved (e.g., lobar, segmental, or subsegmental atelectasis). The length of in-hospital stay was different among groups (p=0.01). This can be caused by: Some people may be more likely than others to have atelectasis. Also talk to them about a device called an incentive spirometer, which helps promote proper breathing. When larger units of lung parenchyma is involved it is called "collapse" (or .
