New in the app: select different inhale / exhale ratios for your sessions

Blog post by Marco Altini

With the next update of HRV4Biofeedback, we are bringing to the app one of the most frequently requested features: the possibility to select other inhale to exhale ratios, apart from the standard 50 / 50

The update will be available in a few days and will provide three options:

• 50 / 50: inhale and exhale are of the same duration. This is the option currently available in the app
• 40 / 60: inhale is 40%  of the cycle, therefore exhale is a bit longer
• 1 / 2: inhale is half the exhale period

​In all cases, the base breathing frequency will be the one you have configured manually or determined via the resonant frequency test. This base frequency will be modulated according to your selection, to allow you to use different ratios
