Sorry if I've not understood correctly, but to use this for a child I would put my phone in their bed, and when the child coughs / wheezes an alarm will sound waking the child and myself up?

Right now yes, it's supposed to be. My friend's child (\~4 months) sleeps in the parent's room, right near their bed, so I thought it might work in this way. Any concerns about that?

Sounds like a baby monitor would provide the exact same functionality without leaving a phone with the child.


doctorforce

Would you be woken up if a child was wheezing through a baby monitor?


trtsmb

Have you ever actually used a baby monitor?


doctorforce

Yes, it probably cost around £20. I can't imagine it would have woken myself or my wife up if my child was wheezing.

Well, the major problem I tried to address is the delay between the actual event of exacerbations and early symptoms.When an asthma attack occurred, it started with reducing the section of the alveolus, which causes the wheezing sound during breathing, and the algo in the smartphone is trying to capture that.What I found is that most of the monitors are relying upon heart rate /respiratory rate/heart rate variability, which does not always explicitly characterize the attack, causing false alarmsSpeaking about the oxygen level, even if it shows correct readings (which is always misleading even in hospital conditions, I worked in Toronto’s children hospital ICU), it provides a signal only post-factual, then regular pulmonary functions are already interrupted for some time.Anyway, even it’s something useless, it’s free for use for anybody:) If I find that nobody is actually using it, I’ll disable servers, and it will just be a project I gained my experience from.

yup, but they cost 300+ bucks, and the app does basically the same (at least for children with asthma) at least the preliminary 1-1 comparisons showed that (not sure how's it generalizes over other people, but it definitely might be fixed)


trtsmb

Most people who have a baby most likely have a baby monitor which are way less than $300. An audio monitor is less than $20.

In that type of situation I could definitely see a use, especially for first time or anxious parents. How are they finding it? I'm picturing my own situation, 2 year old in their own room. My questions would be how well can the app differentiate between wheezing, coughing, and snoring? And can the app set a level of sensitivity when measuring coughing? What I mean is, will the alarm sound from a single cough, a few coughs in a short space of time, or only for coughing fits? Maybe this could be user defined? A very interesting idea, and one I would be very intrigued to see how it develops!


pushthetempo_

\> Maybe this could be user defined? yeah, makes sense probably the problem is that it's kinda not obvious how to adjust it it could be easily changed if some report lots of false alarms \> differentiate between wheezing, coughing, and snoring It's poorly tested (mainly on me, my wife, and my friend's child), but it looks like could be easily detected, the situation with wheezing is OK, and will be improved in the future. Speaking about counting cough, eh , right now it's super-primitive, just trying to catch the caught itself, without analysis of prolongation:)


doctorforce

I'll download and have a play around with it myself! It's good to see people thinking of ways to help children with asthma, so thanks. As it happens, my daughter is poorly which has brought on her asthma, so I was up all night with her last night, and came across your post!
