How does Aerosure work?
Mucus Relief Mode
15Hz: Aerosure transmits vibrations via the oscillating valve to the chest wall to help dislodge mucus from the airways and lungs
Breathe Easier Mode
25Hz: resistance creates an increase in lung pressure and targets muscles of the respiratory system. This helps to work the respiratory muscles harder, which improves respiratory fitness and may result in reduced breathlessness.
In more detail …
- Aerosure provides targeted vibration-training and resistance for the purposes of:
- Respiratory muscle training
- The alleviation of breathlessness
- Assistance with sputum expectoration
- The device produces a rapidly alternating occlusion of airflow as the user breathes through the valve head
- This creates a general increase in resistance to breathing and a vibration of the respiratory tree and associated structures, including the musculature
- This is refered to as high frequency airways oscillation (HFAO)
- Aerosure works by briefly and repeatedly closing and opening the flow of air in to and out of the user’s mouth during respiration:
- When the air flow path is closed, a pressure differential is created between the occluded column of air within the user’s chest and the atmosphere
- By rapidly cycling between a restricted and non-restricted air flow, a pressure oscillation is generated, together with an overall increase in resistance
- Aerosure is electrically driven; so effective regardless of position of user or pressure generated by the user.
- This provides inspiratory muscle training (IMT) effects and oscillatory positive expiratory pressures (OPEP) which, together, result in vibration of the respiratory tree and associated musculature.
