At what flow rate is a nebulizer typically set?

A nebulizer is typically set to a flow rate of 6 to 8 liters per minute. This range is optimal because it ensures that the medication delivered through the nebulizer can effectively aerosolize into fine particles that can be inhaled deeply into the lungs. At this flow rate, the nebulizer is able to generate a consistent mist and maintain adequate delivery of the medication over the duration of the treatment session.

Setting the flow rate too low might result in an inadequate aerosol generation, leading to less effective treatment, while a flow rate that is too high could waste medication and lead to increased velocity of airflow, which may not allow for optimal deposition in the respiratory tract. Therefore, 6 to 8 liters per minute strikes a balance, making it the standard practice for nebulizer use.
