Introduction
The In-Check DIAL G16 is an inhalation airflow training meter that can help
educate and assess patients who use inhaler devices.
Inhaler devices are designed to deliver medication to the respiratory tract,
and the speed of inhalation through them (the inspiratory flow) can have a
significant effect on the quantity of drug delivered and the clinical efficacy of
the product.
The In-Check DIAL G16 is designed to simulate the "internal resistance" of
common inhaler devices, and measure inspiratory flow. These measurements
enable the healthcare professional to encourage patients to modify their
inspiratory technique (by inhaling with more, or less effort), in order to achieve
a flow rate consistent with clinical efficacy. The coloured 'flow' icons show the
clinically effective flow ranges for each different inhaler device. These 'flow'
icons do not imply any comparison between devices.
Patients that cannot achieve the suggested inspiratory flow for their inhaler
may not gain maximum benefit from their prescribed medication, and
healthcare professionals may wish to take this factor into account when
selecting with the patient, the device that is the most suitable.
Inspiratory Flow and Clinically Effective Flow Range
The inspiratory flow through an inhaler is one of the factors that will
influence the clinical effect of the drug delivery from that device. The
most effective delivery occurs when the patient achieves a flow within
the clinically effective flow range. Flow rates outside this range, may
result in a diminished deposition and clinical efficacy.
Inhaler devices
Drug delivery from the various types of inhaler devices is produced by
different methods.
Inhaler devices are designed to deliver drug particles of a certain size
to the small airways during inhalation. Particles of this size (generally
agreed to be approximately between 1 and 5 microns) are known as the
"respirable dose". The particles are either in aerosol (in a suspension
or a solution) or dry powder form.
Pressurised Metered Dose Inhalers (pMDIs)
With most pMDIs, the aerosol is delivered under pressure at high speed
(often over 90 kilometres per hour). The inhalation should be timed with
actuation of the device and should be slow and steady. Inhaling too fast
may cause a greater proportion of the aerosol to impact at the back
of the throat and be subsequently swallowed, thus reducing the
beneficial clinical effect and increasing the potential for local and
systemic side effects.
