• Abstract

  Lung collapse (atelectasis) usually occurs during general anesthesia with mechanical ventilation what could cause hypoxemia and postoperative complications (infection and acute lung injury). The use of low fraction of inspired oxygen (FIO2) and PEEP (Positive End Expiratory Pressure) may reduce the amount of lung collapsed. Currently, there is no device that allows continuous evaluation o…

  Continous lung function analysis using Electrical Impedance Tomography for monitoring of lung collapse and perfusion during general anesthesia., AP.R

• Abstract

  Pulmonary atelectasis is commonly developed during general anesthesia and mechanical ventilation which can cause adverse consequences either intraoperatively or postoperatively. The use of physiological tidal volume (6-8 ml/Kg of ideal body weight) during the intraoperative period to minimize the risk of lung injury is associated with increased amount of atelectasis. The use of PEEP can p…

• Abstract

  Acute Respiratory Distress Syndrome (ARDS) is characterized by shunt and increased dead-space ventilation, resulting in hypoxia and increased carbon dioxide tension with respiratory acidosis. Historically, MV with high tidal volumes (VT=10-15 mL/kg) and high pressures had been recommended in patients with ARDS to ameliorate gas exchange. However, there is convincing evidence suggesting th…

• Abstract

  The acute respiratory distress syndrome (ARDS) increases the morbidity and mortality of patients admitted to the intensive care unit. In the postoperative period of cardiac surgery, the use of intraoperative cardiopulmonary bypass is one of the triggers of the syndrome, increasing its incidence. Potentially a protective ventilatory strategy with optimal PEEP setting individualized and ide…

• Abstract

  Introduction: The alveolar recruitment maneuver (ARM) is used in cases of Acute Respiratory distress syndrome (ARDS) for opening alveolar collapsed units in regions dependent on gravity, which can improve oxygenation and reduce the risk of ventilator induced lung injury. After ARM, the appropriate PEEP setting allows to keep alveoli opened. It is still controversial which is the best appr…

• Abstract

  Studies have shown that an additional reduction of tidal volume (TV<6ml/kg) that promotes a reduction in the driving pressure can cause less injury and pulmonary inflammation determining reduction in mortality. However, the use of low TV is associated with hypercapnia and respiratory acidosis. There are two easy-to-carry out interventions to optimize the CO2 clearance: increase of respira…
