AIM Aerosol Inhalation Trainer

Improve inhaler technique through training


The Vitalograph AIM™ assists medical practitioners in identifying the appropriate inhaler type and in training patients to use their inhaler correctly.

Mastery of the correct technique will support more accurate drug delivery in a range of DPI and MDI inhalers and good patient compliance, resulting in better disease management.

Using a hygienic single-use disposable inhaler simulator, AIM provides clear feedback and information to support correct technique including:

  • Inspiratory acceleration at start of inspiration
  • Timing of firing of MDI
  • Inspiratory flow rate throughout inspiration
  • Inhalation time within target flow range
  • Breath hold time at end of inhalation
  • Inhaler types:
    • MDI
    • DPI
    • Generic
    • DISKUS
    • Ellipta
    • Custom inhaler types are also available.

The battery powered AIM provides accurate and objective live feedback on inspiratory flow rate and breath hold during inhaler use. A summary visual result is displayed to clearly illustrate the difference between good and poor technique. The parts of the inhalation process which a patient has yet to master, including factors that are difficult to observe by eye, are clearly highlighted thereby enabling physicians to concentrate on specific aspects of patient technique.


  • Validates effective use of an inhaler
  • Identifies correct choice of inhaler device type
  • Identifies and quantifies poor inhaler technique
  • Objective identification of proper use of the inhaler device
  • Assists in training patients to use their inhalers correctly
  • Provides clear feedback and instructions to patient and trainer
  • Easy to use, hygienic and low cost
  • MDI, DPI and spacer training options

The AIM is an effective training tool which detects and measures the elements required for correct inhaler technique such as actuation, inspiratory flow rate and breath hold time and compares these with known requirements for effective drug delivery.

The AIM will give either a good, poor or fail indicator, showing which element of the technique caused the problem (if applicable).
