Barotrauma lungs increase lung compliance12/16/2023 ![]() ![]() La mortalidad fue similar en ambos grupos. No hubo diferencias en las presiones ni en los volúmenes respiratorios entre pacientes con o sin barotrauma. Únicamente en estos dos casos se modificó la estrategia ventilatoria. En 7 pacientes fue tan solo de un hallazgo radiológico en los otros dos, se manifestó como un neumotórax bilateral y a tensión, cursando con hipoventilación pulmonar. Nueve pacientes, 7 con neumonía y 2 con trauma torácico, desarrollaron barotrauma (2 enfisema subcutáneo y 7 neumotórax), lo cual supuso una incidencia total del 9% y del 16% en aquellos pacientes con lesión pulmonar primaria. Intervencionesġ) maniobra de reclutamiento pulmonar (MRP) con presión de ventilación fija e incrementos progresivos de presión positiva al final de la espiración (PEEP), seguida de decrementos escalonados hasta establecer la PEEP de apertura en el valor asociado a la máxima distensibilidad respiratoria 2) ventilación asistida/controlada por presión ajustada para un volumen tidal de 6-8 ml/kg y 3) radiografía de tórax después de la MRP y diariamente mientras persistió la insuficiencia respiratoria. DiseñoĮstudio retrospectivo, observacional, descriptivo, en 100 pacientes con insuficiencia respiratoria aguda e infiltrados pulmonares bilaterales. Barotrauma was neither related to high pressures and volumes nor associated with increased mortality.ĭescribir la incidencia y principales características clínicas del barotrauma durante la ventilación mecánica con apertura pulmonar. In most cases, there were only radiological findings without clinical significance that did not require the suspension of OLV. Conclusionsīarotrauma was an exclusive complication of patients with primary lung injury, and the incidence in this group was high. There were no differences in the airway pressures or volumes between patients with and without barotrauma. Only in these two cases was the ventilatory strategy modified. In 7 patients barotrauma was only a radiological finding in the other 2 patients, it manifested as bilateral and tension pneumothorax, inducing pulmonary hypoventilation without hemodynamic impairment. Nine patients, 7 with pneumonia and 2 with chest trauma, developed barotrauma (2 subcutaneous emphysemas and 7 cases of pneumothorax), representing an overall incidence of 9% and 16% in patients with primary lung injury. (1) A lung recruitment maneuver (LRM) with fixed ventilation pressure and progressive positive end-expiratory pressure (PEEP) elevations was carried out, followed by stepwise decreases until establishing open-lung PEEP at the value associated to maximum respiratory compliance (2) assisted/controlled pressure ventilation to achieve a tidal volume of 6–8 ml/kg and (3) chest X-rays after LRM and daily for as long as respiratory failure persisted. DesignĪ retrospective, observational, descriptive study was made of 100 patients with acute respiratory failure and bilateral pulmonary infiltrates. read more after a dive should be referred to a diving medicine specialist for assessment of risks of future dives.To describe the incidence and main clinical characteristics of barotrauma during open lung ventilation (OLV). The main causes of pneumomediastinum are Alveolar rupture with dissection of air into the interstitium of the lung with translocation to. Patients with pneumomediastinum Pneumomediastinum Pneumomediastinum is air in mediastinal interstices. read more may be at risk of pulmonary barotrauma, although many people with asthma can dive safely after they are evaluated and treated appropriately. Patients with asthma Asthma Asthma is a disease of diffuse airway inflammation caused by a variety of triggering stimuli resulting in partially or completely reversible bronchoconstriction. Such individuals should not dive or work in areas of compressed air. read more, or previous spontaneous pneumothorax.

Patients at high risk for pneumothorax Pneumothorax Pneumothorax is air in the pleural space causing partial or complete lung collapse. Proper ascent timing and techniques are essential. Prevention of pulmonary barotrauma is usually the top priority. ![]()
