Descriptor English: Ventilator Weaning
Descriptor Spanish: Desconexión del Ventilador
Descriptor desconexión del respirador
Entry term(s) desconexión del ventilador mecánico
Scope note: Técnicas que permiten efectuar la transición de un paciente con insuficiencia respiratoria desde la ventilación mecánica a la espontánea, mientras que alcancen los criterios de que el volumen de ventilación pulmonar esté por encima de un nivel determinado (mayor de 5 ml/kg), la frecuencia respiratoria sea inferior a un determinado nivel (menos de 30 respiraciones/min), y que la presión parcial de oxígeno esté por encima de un nivel dado (PaO2 mayor que 50mm Hg). Los estudios de desconexión centran su atención en encontrar métodos para monitorizar y predecir el resultado de la desconexión del ventilador mecánico así como para encontrar las técnicas de apoyo ventilatorio que facilitarán la desconexión satisfactoria. Los métodos actuales incluyen la ventilación obligada intermitente, ventilación intermitente de presión positiva, y ventilación obligada de volumen minuto.

Scope note: Techniques for effecting the transition of the respiratory-failure patient from mechanical ventilation to spontaneous ventilation, while meeting the criteria that tidal volume be above a given threshold (greater than 5 ml/kg), respiratory frequency be below a given count (less than 30 breaths/min), and oxygen partial pressure be above a given threshold (PaO2 greater than 50mm Hg). Weaning studies focus on finding methods to monitor and predict the outcome of mechanical ventilator weaning as well as finding ventilatory support techniques which will facilitate successful weaning. Present methods include intermittent mandatory ventilation, intermittent positive pressure ventilation, and mandatory minute volume ventilation.
