VentiChamber

VentiChamber is an anti-static spacer with feedback whistle. Comparative testing demonstrated whistle actuation at flow rates closer to clinically relevant inhalation ranges compared with other inhaler chambers. The device may support inhalation technique..1,2 

The chamber incorporates antistatic material, which reduces electrostatic charge and may support aerosol delivery performance.

Top features

InspirAlert Feedback Whistle

The audible whistle provides feedback during inhalation, with variation in sound indicating changes in inhalation flow. The whistle feedback may support users in maintaining an appropriate inhalation flow rate during use.

SpiraVu Clear Exhalation Port

Unique design directs exhaled medication away from patient’s face.

SealVision Visual Indicator

Integrated flap is designed to confirm the face-to-mask seal, featuring a visual indicator for verification.

Locking MDI Adapter 

Push fit pliable back piece, provides confidence that the MDI is correctly seated. Locks to prevent accidental chamber removal.

One-way Inhalation Valve

Low resistance to airflow.

Comfortable Oval Chamber

Ergonomic1 shape ideal for children and elderly patients. Prevents chamber from rolling when set down.

Built for performance

Comparative testing demonstrated whistle activation closer to target inhalation flow ranges compared to comparator devices.3

The InspirAlert feedback whistle operated closer to the optimum inspiratory flow rate2,5,10,11,12 to ensure medication effectively reaches the lower lungs. 

VentiChamber promotes proper inhaler technique, which is critical for maximising the therapeutic effects of inhaled medications.10,11

Multi-sensory
indicators

We tested VentiChamber using different pMDI inhalers3, as each have their own unique characteristics that can affect how much air is drawn through the inhaler during inspiration.

The VentiChamber whistle activation coaches users to reduce their inspiratory flow rate, which results in a greater lung deposition of medication delivery.

The effect of patients not receiving a high percentage of their prescribed dosage, potentially prolongs their condition.

The role of valved holding chambers
in respiratory care

Valved holding chambers are widely used to support inhaled therapy and may improve aerosol delivery when used with pMDIs.

VHCs act as holding chambers that allow aerosol to be suspended prior to inhalation, which may reduce oropharyngeal deposition and influence lung delivery.6

By mitigating the need for precise coordination between inhalation and medication actuation, VHCs enhance treatment outcomes, particularly in paediatric7 and geriatric populations.

Clinically Validated for Optimal Performance

Research has demonstrated that VHCs significantly reduce common side effects such as throat irritation, dysphonia, and oral candidiasis, which are often associated with inhaler misuse.4,6,7,8

Clinical findings indicate that VHCs improve asthma control, decrease exacerbation rates, and enhance overall patient adherence.8

VentiChamber incorporates audible and visual feedback features that may support correct inhalation technique during use.10,11

Frequently Asked Questions

Spacers are designed to improve medication delivery from a pressurised metered dose inhaler (pMDI).

Spacers function as a reservoir into which an aerosol medication is dispensed to minimize delivery of large, aerosolized particles, and increase the deposition of medication deep into the lungs.

Spacers create space between the medication source (the pMDI) and the patient allowing the medication to break-up into smaller droplets which penetrate deeper into the lungs.

The device must be cleaned before first use and about once a week or more frequently if it’s visibly dirty.

How To Clean VentiChamber

VentiChamber should be disposed of after 30 washes.

Do not use with Dry Powder Inhalers or Nebulisers.

For use by healthcare professionals, trained patients or their carers. The intended patient population is 3 years and older who have been prescribed pMDI medications.

VentiChamber is intended to be used by these patients to administer aerosolised medication from most pressurized Metered Dose Inhalers,(pMDIs).

The intended patient population is 3 years and older who have been prescribed pMDI medications.

The whistle will sound in the range of 10-30L/min for most pMDIs.

A prolonged slight, wavy tone or no tone indicates proper breathing.

If the whistle sounds at a high pitch, continuous tone, patient should slow breathing rate.

SpiraVu is a visual indicator on VentiChamber which will help confirm a correct seal and gives a visual confirmation of correct application.

The SealVision indicator on the mask will move when there is a good seal. The seal is closed during the inhalation and opens during exhalation.

Both SpiraVu and SealVision indicators are colour-coordinated to provide clear visual feedback to the user.

A facemask should be used if the patient cannot achieve an airtight seal using the mouthpiece.

The size of the mask should be determined by the size of the patient’s face. Consult your healthcare professional for guidance.

VentiChamber is Non-BPA (BPA contents less than 0.1mg/ml) and is Latex free.
