[An oxygen delivery device with a jet nebulizer function (Inspiron Nebulizer or Aquapak Nebulizer) can not provide high concentrations of oxygen to adult patients with respiratory failure].
Oxygen delivery devices with a jet nebulizer function are widely used in Japan. The device, utilizing the Bernoulli principle, can provide oxygen concentrations of 24-100%. The present study demonstrated that maximal inspired oxygen concentration provided by this oxygen delivery device is theoretically 60%, as total gas flow is insufficient to meet all inspiratory requirements to provide oxygen concentrations of greater than 60%. This theoretical calculation was verified using a face model to which oxygen was delivered using an Inspiron Nebulizer or Aquapak Nebulizer.
