Final answer:
Post-operative atelectasis involves lung collapse after surgery, presenting with symptoms like respiratory distress and shortness of breath; treatments include respiratory therapies and monitoring using a pulse oximeter, with more severe cases requiring bronchoscopy or CPAP.
Step-by-step explanation:
Post-operative atelectasis is a condition often encountered in the medical field, where there is a partial or complete collapse of a part of the lungs, usually after surgery. Signs and symptoms (S&Sx) that can be experienced by patients include respiratory distress such as shortness of breath, possible wheezing, or coughing. In some cases, if significant enough, decreased oxygenation and shallow breathing may also be noted. Treatment (Tx) for atelectasis may include respiratory therapies, such as deep breathing exercises, spirometry, and in some cases, repositioning the patient to help with lung expansion. In more severe cases, bronchoscopy to remove blockages or continuous positive airway pressure (CPAP) may be necessary to re-expand the alveoli. Monitoring oxygen saturation levels using a pulse oximeter is important, and supplemental oxygen may be provided if needed. Your description of endotracheal intubation during general anesthesia is accurate as it pertains to maintaining an open airway and preventing atelectasis post-surgery.
