Safety Checklist

Before you train with the PrO2, always review this safety checklist. Since you will be breathing in deeply, it is important that both your mouth AND the device are free from loose particles that might accidentally be pulled into your lungs.

• Your mouth is clean. Ideally, brush your teeth if you have eaten recently.
• No loose components on device
• Removable mouthpiece is tightened
• Device powers on and wireless light is blinking
• Filter is attached (optional)

Power on Device

The back of the device contains the power button. Press and release the button. Within a couple seconds, the Bluetooth LED should start blinking. On the display version Ready will be shown on the display.

Open the App

Open the PrO2 app. Choose Login if you already have an account or choose Create a New Account and follow the prompts to register a new account.

Measure FIT

The PrO2 can be used to be used for single breath measurements or full RMT training. In either case, you start by measuring your FIT score.

Click measure FIT.

Inspiratory testing: Exhale all the air out of your lungs and breath in as hard as you can and hold the breath as long as you can.

Expiratory testing: Inhale a full breath of air into your lungs then exhale into the device as hard as you can and hold the breath as long as you can.

At the end of the breath your FIT score will be displayed. Once you have your FIT score baseline breath you can either click Done or Train.

Training

If you click Train after your baseline it will start your training protocol. Follow the same instructions as measuring FIT score. Be sure to do your best with each breath.

Between each breath you will have time to rest. The rest interval decreases with each set. The standard protocol is 6 breaths at 6 different rest intervals: 40, 30, 25, 20, 15 and 10 seconds.
