Using VitaBreath is simple. Just press the start button and wait for VitaBreath to get up to speed. Then put your mouth on the mouthpiece, being careful to create a good seal on the device, and breathe in and out. VitaBreath will sense your breathing pattern and provide the right level of pressure at inhalation and exhalation. When you feel your breath has come back, turn your VitaBreath off, wipe off your mouthpiece, replace the cap, and store it.
