Inconsistent Medication Delivery
A number of factors contribute to effective aerosol delivery for patients
using a Valved Holding Chamber (VHC) with a pressurized Metered Dose Inhaler
(pMDI). Healthcare providers understand the significance of the details that
go into the manufacture of these devices, but patients will need to be
educated how a carefully designed device can contribute to better disease
management through consistent drug delivery.
Features like an anatomically designed facemask or feedback mechanisms like
those found on the AeroChamber Plus* VHC with Flow-Vu*
Inspiratory Flow Indicator helps caregivers feel secure in knowing proper
technique is being used. A study by Crompton et al recommended all
chambers have a way of confirming that inhalation is being performed
correctly to encourage better compliance and thereby better disease
management.1
Helping your patients understand how these features can improve their
technique and identifying the proper device to meet their needs is critical
to good disease management.
The AeroChamber* Brand of VHC has been carefully designed to
include a number of characteristics that promote consistent medication
delivery, such as:
Compact size to minimize the number of breaths required to empty the chamber
-
Anti-static materials or equivalent pre-treatment of transparent materials
-
Responsive inhalation valves
-
Capability to observe valve movement
-
Ability to observe and ensure a good facemask seal to face
-
Anatomically designed products to minimize dead space in facemask
-
Exhalation valve in facemask to minimize re-breathing and offers low-resistance to dead space
-
Clear instructions for washing and pre-treatment both before use and at specified intervals
