Helping patients control Asthma & COPD 

1st February 2024

Flo-Tone CR (Controlled Resistance) is a reusable training device with a built-in positive whistle that fits onto the mouthpiece of most aerosol inhalers. It emits a positive whistle sound which responds at the same flow rate of the inhaler, irrespective of the inhaler’s individual resistance. 

As a patient starts to inhale, the whistle provides a clear positive signal to actuate their inhaler and they will hear the whistle sound maintained as the medication is drawn deep into their lungs.  

Flo-Tone CR is part of our Respiratory Management Toolkit which helps you to diagnose, assess, train and control Asthma or COPD.

Clinically Proven

In a 2022 study, using the urinary salbutamol excretion pharmokinetic model, a significant increase was shown of drug deposition in the lungs of the Clip-Tone and Flo-Tone + pMDI cohort compared with using pMDI alone. There was no difference between the Clip-Tone and Flo-Tone groups, showing equal efficacy.
