Article information

Over the last 10 years, noninvasive ventilation has become a treatment option for respiratory insufficiency in pulmonology services. The technique is currently included in pulmonology teaching programs. Physicians and nurses should understand the devices they use and the interaction between the patient and the ventilator in terms of respiratory mechanics, adaptation, and synchronization. We present a readily assembled lung simulator for teaching purposes that is reproducible and interactive. Based on a bag-in-box system, this model allows the concepts of respiratory mechanics in mechanical ventilation to be taught simply and graphically in that it reproduces the patterns of restriction, obstruction, and the presence of leaks. It is possible to demonstrate how each ventilation parameter acts and the mechanical response elicited. It can also readily simulate asynchrony and demonstrate how this problem can be corrected.

Key words:
Noninvasive ventilation
Lung simulator
Patient ventilator-interaction
Asynchrony
Leaks

Desde la última década la ventilación no invasiva se ha incorporado al tratamiento de la insuficiencia respiratoria en los servicios de neumología, y actualmente forma parte del plan de formación de esta especialidad. Médicos y enfermeras deben conocer los equipos con los que trabajan y entender la interacción que se produce entre el paciente y el ventilador en términos de mecánica respiratoria y de adaptación y sincronización. Presentamos un modelo de simulador de pulmón de fácil montaje, reproducible e interactivo, que permite alcanzar estos objetivos. Basado en un sistema de bagin-box, este modelo permite aprender de forma sencilla y gráfica la mayoría de los conceptos de la mecánica respiratoria en ventilación mecánica, pues reproduce patrones de restricción, obstrucción o presencia de fugas. Puede comprobarse cómo actúa cada parámetro del ventilador y la respuesta mecánica que genera, y permite simular numerosas asincronías, así como el modo correspondiente de corregirlas.

Palabras clave:
Ventilación no invasiva
