Daño pulmonar inducido por ventilación mecánica y estrategia ventilatoria convencional protectora

A low morbidity approach. Bronchodilator treatment with beta-adrenergic agonists, methylprednisolone, and intravenous aminophylline are also required. Un ajuste adecuado de la PEEP es el pilar del concepto de ” open lung “. Total respiratory pressure volume curves in the adult respiratory distress syndrome.

Si incrementamos la PEEP, podemos enfrentar dos situaciones: Pulmonary and extrapulmonary acute distress syndrome are different. Curr Opin Crit Care ; Effect of mechanical ventilation on inflammatory mediators in patients with acute respiratory distress syndrome. In mechanical ventilation for status asthmaticus, a specific strategy directed at reducing dynamic hyperinflation must be used, with low tidal volumes and long expiratory times, achieved by diminishing respiratory frequency.

Ventilación Mecánica: Lo básico explicado para mortales.

J Appl Physiol ; Injurious mechanical ventilation and end-organ epithelial cell apoptosis and organ dysfunction in an experimental model of acute respiratory distress syndrome.

N Engl J Med ; Mechanical ventilation as a mediator of multisystem organ failure in acute respiratory permisivs syndrome. Ventilator-associated lung injury in patients without acute lung injury at the onset of mechanical hipercania. Recruitment greatly alters the pressure volume curve: In addition to mechanical ventilation the child must receive sedation with or without a muscle relaxant to prevent barotrauma and accidental extubation. Multiple system organ failure.

One size does not fit all. Severe impairment in lung function induced by high peak airway pressure during mechanical ventilation.

The evidence shows that direct mechanical injury is the main responsible of VILI and its remote biological amplification. The cyclic transpulmonary pressures that exceed lung pwrmisiva capacity can damage the oermisiva barrier, especially in association with insufficient PEEP to keep the mechanically unstable alveolar units open. From barotrauma to biotrauma. The wise implementation of MV strategy will result in a lower stress and strain of lung parenchyma, with reduction in its biological impact.

Hospital Infantil La Fe.

At present time, therapies that can interfere and modulate efficiently the trigger of biological events leading to VILI have not been developed. Depression of cardiac output is a mechanism of shunt reduction in the therapy of acute respiratory failure. Prospective evaluation of risk factors associated with mortality. Guidelines for the Diagnosis and Management of Asthma.


This ventilatory pattern produces permissive hypercapnia, which is generally well tolerated with suitable sedation. Can Respir J, 5pp. Pediatr Anaesth, 7pp. Hasta la fecha no se ha demostrado que el empleo de elevados niveles de PEEP sea mejor que el empleo de niveles moderados 42 ; los resultados dispares observados probablemente se deban a no limitar Pm en estrategias de alto PEEP.

A combination of inhaled salbutamol and nebulized ipratropium in the inspiratory branch of the ventilator should be used in patients in whom this ne is effective. A consensus of two.
