摘要This study compares the accuracy and capabilities of various ventilators using a paediatric acute respiratory distress syndrome lung model. Various compliance settings and respiratory rate settings were used. The study was done in three parts: tidal volume and FiOhttp://aims.cuhk.edu.hk/converis/portal/Publication/2 accuracy; pressure control accuracy and positive end-expiratory pressure (PEEP) accuracy. The parameters set on the ventilator were compared with either or both of the measured parameters by the test lung and the ventilator. The results revealed that none of the ventilators could consistently deliver tidal volumes within 1 ml/kg of the set tidal volume, and the discrepancy between the delivered volume and the volume measured by the ventilator varied greatly. The target tidal volume was 8 ml/kg, but delivered tidal volumes ranged from 3.6-11.4 ml/kg and the volumes measured by the ventilator ranged from 4.1-http://aims.cuhk.edu.hk/converis/portal/Publication/20.6 ml/kg. All the ventilators maintained pressure within http://aims.cuhk.edu.hk/converis/portal/Publication/20% of the set pressure, except one ventilator which delivered pressures of up to http://aims.cuhk.edu.hk/converis/portal/Publication/27% higher than the set pressure. Two ventilators maintained PEEP within 10% of the prescribed PEEP. The majority of the readings were also within 10%. However, three ventilators delivered, at times, PEEPs over http://aims.cuhk.edu.hk/converis/portal/Publication/20% higher. In conclusion, as lung compliance decreases, especially in paediatric patients, some ventilators perform better than others. This study highlights situations where ventilators may not be able to deliver, nor adequately measure, set tidal volumes, pressure, PEEP or FiOhttp://aims.cuhk.edu.hk/converis/portal/Publication/2.
