The Flow-Vu* Indicator is especially useful for caregivers as it allows them to:
- Ensure the mask or mouthpiece is applied correctly creating a secure seal
- Coordinate pressing the puffer at the start of inhalation
- Count the number of breaths taken to ensure all of the medication is received
Flow-Vu* Inspiratory Flow Indicator – the most important advancement in chamber technology.
The AeroChamber Plus* Flow-Vu* chamber may have either a mask or mouthpiece – and will hold the medication for a short time until you are ready to inhale it. Without the chamber, medication may get trapped in your mouth or throat, which can leave a bad taste which often means that some of the medication isn't reaching your lungs.
To be most effective, the inhaler should be pressed during inhalation to optimize the medication delivery to the deepest part of the lungs. Effective delivery of the medication to the lungs is difficult because inhalers deliver the medication dose at a very high rate of speed. The AeroChamber Plus* Flow-Vu* Chamber slows the speed of medication and their anti-static body holds it in suspension until you are ready to inhale it.

Bisphenol A (BPA) is a controversial chemical that is used to enhance the clarity and durability of some clear, plastic products. The use of BPA is the subject of discussion, research and public scrutiny as it may lead to negative health effects.1
Though current findings indicate low health risks from exposure to BPA, experts have been unable to come to an agreement regarding appropriate safe levels for consumer products.2 Nevertheless, the Government of Canada has taken steps to ban the use of BPA in baby bottles to reduce newborn and infant exposure.
Trudell Medical International has chosen to be proactive and manufacture the AeroChamber Plus* Flow-Vu* chambers without any BPA to eliminate any patient risk. The medications taken with our chambers are critical to your health and, as the #1 Brand recommended by pharmacists and physicians,3,4 it is our responsibility to lead in the development of innovative, consumer friendly products.

Different valved holding chambers can deliver different amounts of inhaled medication. When prescribing a valved holding chamber it is important to give due consideration to the chamber that is listed on the Metered Dose Inhaler Summary of Product Characteristics (where specified by name).2
The AeroChamber Plus* Brand of Chamber is listed on the following leading metered dose inhaler’s companies’ Summary of Product Characteristics3:
- Airomir† – IVAX Pharmaceuticals UK
- Alvesco† 40, 80 and 160 – Nycomed, UK
- Atrovent† Inhaler CFC-Free – Boehringer Ingelheim , UK
- Fostair† 100 – Chiesi Ltd, EU
- Qvar† 50/100 – IVAX Pharmaceuticals UK
- Sabumalin† 100 – Aeropharm GmbH, EU
- Seretide† Evohaler† 44 / 110 / 220 – GlaxoSmithKline, EU
- Zenhale† – Merck Canada Inc.
- Clinical data with AeroChamber* Brand of VHC included in Flovent† HFA and Ventolin† HFA inhalation aerosol product monographs
- Any child under the age of 6 that uses an inhaler
- Anyone taking inhaled corticosteroids
- Elderly patients that use an inhaler
- Anyone who has difficulty coordinating actuation of their inhaler with inhalation
Device SelectionDifferent patients have very different needs, so we designed each of our products with this in mind. The Flow-Vu* Indicator provides feedback of correct use – and can only be found on AeroChamber* brand of chambers.

Improper mask fit or design can lead to gaps – as small as ½ cm – which may allow ambient air to enter the mask and reduce medication delivery to the lungs by more than 50%.5
The anatomically designed ComfortSeal* Masks minimize the amount of dead space (the space between the valve and the patient). Patients find this comfortable as it requires less pressure to form a secure seal. In addition, the EZ Flow Exhalation Valve, Flow-Vu* Indicator and Alignment Feature all help parents and caregivers ensure that the chamber is assembled and applied to the face correctly.
A recent study tested 7 commonly used facemasks and found the ComfortSeal* Masks incorporated in our Valved Holding Chambers have the lowest dead space volume6 resulting in improved aerosol delivery efficiency. This is due in part to the integrated Exhalation Valve that minimizes re-breathing and directs exhaled flow away from the patient's face.
To ensure your patient is using a properly fitted mask, please download our custom Mask Sizer (see left hand column).
- BPA is an endocrine disruptor, which can mimic the body's own hormones and may lead to negative health effects1
- Use of BPA in products continues to be a subject of discussion, research and public scrutiny - with experts unable to agree on 'safe' levels of exposure2
- Health Canada has moved to ban the use of BPA in baby bottles
- Trudell Medical International has chosen to migrate to BPA free technology to eliminate any risk that may be present
- Mouthpiece Cap
Protects the mouthpiece from dirt and debris when the device is not in use.
- Exhalation Valve
Valve closes upon exhalation to retain any medication inside the chamber for the next breath.
- Flow-Vu* Inspiratory Flow Indicator
Moves as the patient breathes and helps provide assurance that inhalation is being performed correctly by allowing caregivers to ensure a secure seal, coordinate actuation with inhalation and count patient breaths.
- Alignment Feature
Helps align the Backpiece for proper assembly after cleaning.
- FlowSignal* Whistle
Provides audible feedback when the patient is inhaling too rapidly, encouraging proper inhaler technique.
- Universal Backpiece
Can be used with all commonly prescribed Metered Dose Inhalers.
- Clear Anti-Static Chamber
Requires no pre-treatment and provides consistent drug delivery right out of the package.
- Inhalation Valve
Valve is responsive to very low inspiratory efforts, ensuring medication is delivered during acute exacerbations when flow rates can be significantly reduced. Special 'low-flow' valves in pediatric and youth chambers.
- ComfortSeal* Masks
The anatomically designed ComfortSeal* Masks have a flexible, curved lip to ensure a reliable seal with as little as 0.7 kg applied force6 (gentle). Exhalation valves mean the chamber can remain in place so patients do not have to remove the device to exhale.
Targeting drugs to the airways: the role of spacer devices
Results: Spacers minimise problems of poor inhalation technique with pMDI, reduce oropharyngeal deposition and increase lung deposition. Spacers improve the clinical effect of inhaled medications, especially in patients unable to use a pMDI properly. Compared to both pMDIs and dry-powder inhalers, spacers may increase the response to ß-adrenergic bronchodilators, even in patients with correct inhalation technique. A pMDI plus spacer has proven to be a viable lower cost alternative to the use of a nebuliser for delivering large brochodilator doses in patients with severe acute asthma, or chronic obstructive pulmonary disease. Lavorini F and Fontana GA. Expert Opin Drug Deliv (2009);6(1):91-102.
Developing a “Universal” Valved Holding Chamber Platform with Added Patient Benefits Whilst Maintaining Consistent In Vitro Performance
Two recent improvements made to the AC plus VHC to mitigate electrostatic charge and provide visual feedback to users have not affected in vitro performance compared with the original nonconducting VHC. These devices also provide comparable delivery of fine particles to the pMDI alone in the likelihood that the user delays inhalation after actuating their inhaler. Jolyon P. Mitchell, Mark W. Nagel, Heather A MacKay, Valentina A. Avvakoumova, and Jamie Malpass. Respiratory Drug Delivery Europe 2009.
Importance of Patient-Friendly Features to Address Lack of Inhaler Compliance: A Laboratory Evaluation of an Inspiratory Flow Indicator as a Feedback Aid for a Valved Holding ChamberResults: Fine particle mass/actuation (FPM2s) for pMDI alone (mean±SD) was 34.8±1.4 μg, compared with 33.2±3.3 μg/actuation for the pMDI+VHC group. The IFI moved from the inhalation valve closed to open position immediately upon initiation of sampling. Conclusions: The IFI provided feedback on the delivery of this widely prescribed ’rescue’ medication and did not interfere with the new VHC, delivering substantially comparable FPM2s to that from the pMDI alone. It should therefore aid patient compliance. Mitchell J, Nagel M, Malpass J. Journal of Aerosol Medicine and Pulmonary Drug Delivery, Vol 24, #3, 2011, 46,. P-075..
