The Clearway 2 device combines three therapy options;
• Mechanical Insufflation-Exsufflation (MI-E)
• Intermittent Positive Pressure Breathing (IPPB)
• Non-Invasive Ventilation (Therapeutic use only)
IPPB mode and NIV mode must only be used non-invasively.
When used as a mechanical ‘insufflator-exsufflator’ (MI-E), it provides a
positive pressure to the airway, followed rapidly by a negative pressure to
promote the removal of secretions. This is achieved through increasing the
expiratory flow from the lungs, in order to replicate normal cough function.
Optional oscillatory vibrations may assist in loosening and mobilising the
secretions further while the remaining rapid shift to negative pressure results
in achieving a sufficient expiratory flow rate from the central airway, which
enables the clearance of respiratory secretions.
Individuals who may benefit from the use of the Clearway 2 include any patient
with an ineffective cough due to;
• Muscular Dystrophy
• Amyotrophic lateral sclerosis (ALS) or Motor Neurone Disease (MND)
• Myasthenia Gravis
• Poliomyelitis
• Other Neurologic Disorders
• Spinal Cord Injury
The Clearway 2 can be used for Intermittent Positive Pressure Breathing
(IPPB) and therefore may also be used in patients with bronchopulmonary
disease to promote effective secretion removal and or lung volume
recruitment, patient with the following conditions may benefit from using the
Clearway 2 for IPPB;
