Asthma care,
one step ahead.

Sentinel Rhythm Health is developing AirHalo, to help families and their care teams make better decisions about a child's asthma in the moments between clinic visits — when it matters most.

The problem

Between clinic visits, parents manage a child's asthma blind.

Acting early is what keeps a flare from becoming an emergency. But at home, at night, a parent has an inhaler and a guess.

Invisible between visits

Families can't see what is happening in a child's lungs. Between appointments they are left to interpret symptoms on their own.

Acting late is dangerous

Early action keeps a flare from becoming an emergency — but the first signs are easy to miss until things are already severe.

Guessing wrong is costly

Overreact and it's an emergency-room visit for what turns out to be a chest cold. Wait too long and a child ends up needing far more care.

The scale

Millions of families face this every night.

4.8M U.S. children have asthma.
1 in 15 U.S. children are affected.
#1 Most common chronic disease of childhood.
$80B+ Spent on asthma in the U.S. each year, across all ages.

Our product

AirHalo

AirHalo is in development at Sentinel Rhythm Health. It is designed to give families and their care teams better information at the moment asthma symptoms start — so the decision about what to do next rests on more than a guess.

We share more detail directly with clinicians, researchers and prospective partners as the work progresses. Get in touch if that’s you.

Development status. AirHalo is an investigational device under active development at Sentinel Rhythm Health. It is not cleared or approved by the U.S. Food and Drug Administration and is not available for sale. Nothing on this site is medical advice — always follow the asthma action plan you have agreed with your clinician.
