WheezeScan is designed to help parents detect wheeze in children with asthma symptoms.

WheezeScan is a tool designed to help parents detect wheeze in children with asthma symptoms. WheezeScan analyzes a child’s breathing to quickly and accurately tell whether or not a child is wheezing, helping to:

  • Remove doubt in the moment of breathing distress
  • Know when and how to follow a doctor’s treatment plan

Product benefits

Quick and accurate
WheezeScan quickly and accurately confirms whether or not a child is wheezing—giving treatment confidence in the moment of breathing distress.

Innovative listening technology
Only WheezeScan uses advanced listening technology to confirm “wheeze” or “no wheeze” with accuracy, even when it occurs at low volumes that you may not be able to hear.

Asthma Diary app
With its complimentary mobile app, WheezeScan does more than accurately detect wheeze. The app allows for logging of wheeze episodes, symptoms, and triggers that can be shared by parents to help you manage their child’s care. Compatible with iOS 10 and above, and Android OS 7 and above.

Wheeze identification challenges

55% of parents identified wheeze differently than clinicians in 1 study.1 Studies found up to 40% of parental reports of wheeze were unreliable.2,3 Parents and caregivers tend to underestimate the severity of their child’s asthma and overestimate asthma control. This is viewed as a major barrier to successful management in children.4

In a qualitative study, caregivers often experienced fear and uncertainty when managing continuing wheeze symptoms with no definitive diagnosis, which resulted in frequent visits to the emergency department.4 A 2013 systematic review found that increased parenting stress is associated with poor psychological adjustment in both caregivers and children and this may contribute to poorer child health outcomes.

Introducing WheezeScan

Read what doctors think about WheezeScan

“Research shows that parents and clinicians agree on the presence of wheezing only in 45% of the cases 3, which reveals the urgent need for a more objective identification of wheeze. From this perspective, we receive the development of the WheezeScan with enthusiasm, which accurately detects wheeze or no wheeze in the critical moment, so that parents can make the right treatment decision”.

Prof. Dr. Wim van Aalderen
Pediatric Respiratory Medicine in the Amsterdam Medical Center, Amsterdam, The Netherlands

“Wheeze is a common asthma symptom in children. But despite its commonality, a wheeze can be a difficult symptom for parents to accurately report on, especially in younger children who are not able to verbally communicate. Research has shown that parents and clinicians disagree on the presence of a wheeze in over half (55%) of consultation instances.

The WheezeScan device can be utilised by parents of asthmatic children to assess a child who may be showing early signs of an asthma attack. It can help a parent to correctly identify wheeze and respond with treatment, rather than waiting to see if other symptoms develop. It can also help parents feel more confident when relaying information to the child's medical team”.

Dr. Zoe Williams

“Wheeze is common among children - 2 in 5 children have at least one bout of wheezing by the time they turn 6 years old. And, for parents and children alike, often scary, especially if asthma is involved. If your young child has been diagnosed with asthma, knowing when they’re wheezing isn’t as easy as you might think – up to 3 in 5 parents don’t recognise that a young child is wheezing. That’s a concern because giving the right treatment early greatly reduces the chance of a severe asthma attack. By the same token, giving inhaled medicine often ‘just in case’ can result in your child having more medication than they need”.
