Effects on the Expiratory Flow of AAD in a Critical Patient With IMV

One of the detrimental effects of invasive mechanical ventilation (IMV) is the alteration of the patient's mucociliary system that requires ventilatory support. The consequence of poor drainage of secretions, triggers secretion retention, atelectasis, and ventilator-associated pneumonia (VAP). Respiratory physiotherapy in the intubated patient facilitates the mobilization of retained and impacted secretions in the bronchial tree, decreasing resistance, improving lung compliance, and decreasing respiratory muscle work. The main objective of the present study is to measure the expiratory flow generated by the application of the DAA technique in the intubated patient during, after, at the end of the technique and at two hours. As secondary objectives, it is proposed to observe whether the application of the DAA maneuver in the patient with IMV improves oxygenation, produces changes in respiratory mechanics, improves air entrapment, decreases exhaled volume post DAA and analyzes the tolerance of DAA in IMV-conscious patients The study will be performed on patients admitted to the Intensive Care Unit (ICU) of the Parc Taulí University Hospital in Sabadell with IMV requirements. The intervention will consist of performing a respiratory physiotherapy session as usual in the daily clinical practice of the ICU, specifically the technique of assisted autogenous drainage, before, during and after the Better CareTM platform will be used to continuously record the physiological variables. necessary for the study.
