What is a characteristic of soft mist inhalers?

A characteristic of soft mist inhalers is that they are handheld and produce small particles. This design is significant because soft mist inhalers utilize a specific mechanism to aerosolize medication, allowing for fine particles that are typically between 1 to 5 micrometers in size. These small particles are crucial for deep lung delivery, as they can reach the lower airways more effectively than larger particles.

The ability to produce a soft mist allows for a slower, more prolonged inhalation, which can improve medication deposition in the lungs and reduce oropharyngeal deposition. This characteristic enhances the overall effectiveness of the inhalation therapy, making soft mist inhalers an effective choice for patients requiring respiratory medications.

The other options do not accurately capture the unique characteristics of soft mist inhalers. For example, while some inhalers do contain propellants, soft mist inhalers typically do not function on that principle; instead, they create aerosolized medication through a mechanical process. Breath-actuation is also a feature distinct to some inhalers, but not all soft mist inhalers operate this way – they may allow for manual actuation. High inspiratory flow rates are generally not required for soft mist inhalers, making them easier to use for patients who may struggle with
