Loss-of-surfactant atelectasis occurs when the surface tension of an alveolus increases because of reduced surfactant action. 2010-06-01 · Absorption atelectasis In an adult subject, the resting lung volume (functional residual capacity, FRC) is reduced by 0.7–0.8 l by changing the body position from upright to supine, and there is a further decrease by 0.4–0.5 l with the induction of general anaesthesia 7 (Fig. 3). Se hela listan på radiopaedia.org If a large volume of nitrogen in the lungs is replaced with oxygen, the oxygen may subsequently be absorbed into the blood, reducing the volume of the alveoli, resulting in a form of alveolar collapse known as absorption atelectasis.

In addition to airway characteristics, other features of atelectasis are important. Atelectasis describes loss of lung volume secondary to collapse. It has many causes, the root of which is bronchial obstruction with absorption of distal gas.

Using lower FIO2 (30%) during induction can effectively decrease the amount of atelectasis, however this is associated with a lower safety margin is patients who may be difficult to intubate.

2020-12-16 · Atelectasis is a loss of lung volume that may be caused by a variety of ventilation disorders, for instance, bronchial injury or an obstructive mass such as a tumor. It may be categorized as obstructive, nonobstructive, postoperative, or rounded. 2020-07-18 · Absorption atelectasis developed within 5 min in the F io 2 1.0 group and after 40 min in the F io 2 0.4 group. Although the impact of oxygen concentration was obvious, this and the present study differed in that the previous study applied the designated F io 2 not only during RM, but also during the rest of the study period. 2015-12-01 · Absorption atelectasis occurs more often in anesthetized patients because of two factors, namely hyperoxygenation and a low ventilation-perfusion (V/Q) ratio. When a patient is undergoing anesthesia, they will often be placed on 100% oxygen before placement of an artificial airway.

PMID: 8669602 Absorbative atelectasis, also called denitrogenation absorption atelectasis, is the collapse of the alveoli due to the loss of the partial pressure of nitrogen within the lungs. 4 Thus at higher Se hela listan på mayoclinic.org Absorption atelectasis can occur by either complete airway occlusion or by reduction of the inspired ventilation-perfusion ratio (V AI /Q) to below a critical level .
