WebOne of the adverse consequences of such a pre-oxygenation strategy is pulmonary atelectasis. High concentrations of inspired oxygen result in absorption atelectasis, even … WebDuring anaesthesia the combination of breathing at low lung volume, the administration of nitrous oxide and high inspired oxygen concentrations produces conditions that favour absorption atelectasis. Measures such as adding nitrogen to the inspired mixture and avoiding high inspired oxygen concentra …
WebAtelectasis during general anesthesia may be prevented by limiting the fraction of inspired oxygen ([F io 2] “absorption atelectasis”) 4 and by promoting alveolar recruitment with positive end-expiratory pressure (PEEP) and recruitment maneuvers. 5 The effectiveness of these interventions has been thoroughly investigated during induction and maintenance … WebMar 24, 2011 · Potential complications of oxygen therapy include absorption atelectasis, apnea with loss of respiratory drive in patients with chronic respiratory failure, retinopathy of prematurity, and oxygen toxicity (see Potential complications of oxygen therapy).

WebFrom this body of research, it appears that absorption atelectasis does occur in healthy anesthetized adults breathing 100% oxygen. Data reviewed suggest that absorption atelec- tasis does not have significant clinical implications in healthy adults.
WebBackground. The use of 100% oxygen during induction of anesthesia may produce atelectasis. The authors investigated how different oxygen concentrations affect the formation of atelectasis and the fall in arterial oxygen saturation during apnea.Methods.
