Cautions A caution indicates the possibility of damage to the device. • Condensation may damage the device. If this device has been exposed to either very hot or very cold temperatures, allow it to adjust to room temperature (operating temperature) before starting therapy.
1.5 System Overview The CoughAssist T70 removes secretions in patients with an ineffective ability to do so on their own. The device clears secretions by providing high frequency oscillatory vibrations while gradually applying a positive pressure to the airway, then rapidly shifting to a negative pressure. The rapid shift in pressure produces a high expiratory flow rate from the lungs, simulating a natural cough.
