In-Check DIAL G16

Guiding correct DPI & pMDI inhalation rate

Many patients do not use their inhalers correctly, failing to inhale at the correct flow rate. International asthma management guidelines call for inhaler review.

In-Check DIAL G16 enables healthcare professionals to coach patients to use their inhalers correctly. The device measures peak inspiratory flow rate, and can simulate the resistance characteristics of the specific inhaler of a patient, providing the device is set on the correct setting. The patient can then be trained to inhale at a flow rate known to be suitable for their personal DPI or pMDI.

The In-check DIAL has been revised

The changes made

The former In-Check DIAL has been revised, now grouping inhalers as a function of their internal airflow resistance, in order to accommodate information on the new devices. There are six resistance groups, five of which relate to dry powder inhalers (DPIs) and one of which to pressurised metered dose inhalers (pMDIs). A guide to identify the resistance group for each inhaler is provided on the In-Check DIAL G16 and on the associated guide. The ability to use In-Check DIAL G16 to measure specific flow rate of a particular inhaler can still be achieved through the use of a specific restrictive adapter. An example adapter is now included in the pack.

Clinical efficacy

The In-Check DIAL can be set to a resistance setting to match any particular inhaler by identifying the inhaler from the chart and selecting the appropriate resistance setting. When the patient inhales their inspiratory flow rate will be shown by the pointer.

Clinical efficacy

The aim is to encourage flow rates that are within the green band indicating the range of flows consistent with clinical efficacy. The arrows within the bands indicate that for DPIs a stronger flow is generally to be aimed for and for pMDIs the opposite applies, a gentle technique is better. Having acquired the correct flow rate patients can then apply this to their inhaler.

5 resistance settings that relate to DPI

pMDI setting

In-Check DIAL offers five resistance settings that relate to DPIs; high, medium-high, medium, medium-low and low. A guide to the resistance of individual inhalers is provided. Additionally a sixth resistance setting represents the average resistance of pMDIs.

How to use adapters

Setting ‘0’ pMDI

Specific adapters are available for the following devices:- 

  • Turbohaler
  • Promedica
  • HandiHaler
  • Diskhaler 4 Blister
  • Clickhaler
  • Easyhaler
  • Autohaler/Accuhaler/Discus
  • Easybreath
  • Foradil
  • Accuhaler/Discus
  • Easybreath- Breezhaler/Foradil
  • Grenuair
  • Evohaler - freeflow setting

To use adapters the In-Check DIAL must be set to position O (pMDI) and the adapter connected between the IN-Check DIAL and the disposable mouthpiece.

Multi-patient use

The In-Check DIAL is a tool for doctors, nurses and pharmacists to use and is intended for multi-patient use. Individual patients should use a one-way disposable inspiratory mouthpiece, which should be discarded after use. The In-Check DIAL may be washed in soapy water in accordance with instructions.

Disposable inspiratory one-way valve mouthpieces

Minimise cross infection

Infection control has become a critical issue in healthcare. Clement Clarke offer a wide range of mouthpieces, designed to minimise cross infection between patients, making many devices safe for multi-patient use.
