Microphone for NIV masks

Useful insight

I would love it if a microphone could be invented for Non-Invasive Ventilation (NIV) masks so that our elderly patients can hear and understand us whilst having their therapy, rather than taking the mask off to communicate and therefore losing the benefits of the mask.

Hi Stuart! This is fantastic to see a post from someone who is working with patients. Could you be so kind to tell us more about non-invasive ventilation masks? I never saw one but I found a few pictures and found some masks which do not cover the ears. I wonder why it is hard for people to hear with it - does the mask make loud noise, and, if so, how loud? Also, is it harder to hear the patient with a mask or impossible? Why do you think it is so? Sorry if my questions are too silly - I just want to learn about these masks more. Thank you in advance!

These masks working by putting a gentle positive pressure into the lungs to increase lung volume. Gaseous exchange is maximized with larger surface volumes and these masks help the alveoli unfold and expand undoing the collapse through pneumonia or other such insults. Taking the mask off to communicate stops the effectiveness of this therapy instantly. The masks do not stop the patient hearing, more their ability to speak, which can be difficult as already short of breath, anxious and now tiring. The machine isn't particularly noisy, but with covid we find it very difficult to hear our patients with all the PPE involved. A simple microphone that could be stuck inside the mask would ensure constant communication and the continuation of the NIV therapy and therefore reduce the time required to help these patients recover.

Thank you for your reply, Stuart! So, I see that it's best that patients don't remove the masks. Do I understand you correctly that if patients try to speak with mask on, they can do that but you won't hear them, correct?

yes it can be really difficult to understand the patient once these masks are applied.

I understand now. Yes, the idea with microphone inside the mask is fantastic. I can imagine myself with the mask, wanting to communicate with medical personnel or my loved ones. Thank you, Stuart!
