Cystic fibrosis – home airway clearance as part of daily therapy
Cystic fibrosis is an inherited condition in which the body produces very thick, sticky mucus. When this accumulates in the airways it makes breathing harder and can provide a focus for recurrent infections. That is why regular, daily airway clearance is a fundamental part of cystic fibrosis care. An oscillating airway clearance device (OPEP) can help by supporting mechanical mobilisation and coughing up of thick secretions – and salt therapy may help loosen the mucus.
Important – read this first
For cystic fibrosis, the method, device and daily schedule for airway clearance are always determined by the treating physician or the respiratory therapist as part of the therapeutic protocol. The devices shown here are intended to fit into that professional care — they do not replace it, and consultation with the treating physician is essential before introducing them. The information below is general and does not substitute personalised medical advice.
The SaltDome salt therapy device is a home respiratory support device recommended for the treatment of chronic respiratory complaints. It can be used for COPD, asthma, respiratory allergy, the common cold, exercise-induced asthma, and even to ease breathing problems in pets — dogs and cats.
OPEP — an oscillating positive expiratory pressure device that can help clear airway secretions that block the airways in COPD, cystic fibrosis and pneumonia.
How does airway clearance help in cystic fibrosis?
The biggest challenge in cystic fibrosis is the very thick, sticky secretions that build up in the airways. The aim is to remove this mucus regularly so breathing is easier and the risk of infections is reduced. Two methods are commonly used together – OPEP as the main tool to mobilise secretions, and salt therapy to help loosen the mucus.
When you exhale into an oscillating positive expiratory pressure (OPEP) device, it creates vibrations and a slight back pressure. The vibration loosens thick secretions stuck to the airway walls, and the back pressure helps keep the airways open so mucus can move into larger bronchi — from where it can be coughed up. In cystic fibrosis this can be one element of daily airway clearance, assisting mechanical removal of viscous secretions. Device choice and daily scheduling are made in consultation with the treating physician.
A salt‑therapy device delivers tiny inhalable salt particles into the air. Salt that reaches the lungs can attract water to the mucus, which may help dissolve and loosen thick secretions so they are easier to mobilise. In cystic fibrosis, salt therapy may be used alongside mechanical airway clearance (OPEP) to prepare the mucus. As with all elements of care, its use should be discussed with the treating physician.
The two methods together
The logic is similar to other mucus‑producing respiratory conditions: salt therapy helps dissolve and loosen thick mucus, and OPEP moves it and enables coughing it up. In cystic fibrosis the emphasis is on regular, medically supervised daily airway clearance — the exact device combination and protocol are set by the treating physician or respiratory therapist and tailored to the individual.
Important information and limitations
Airway clearance in cystic fibrosis is part of the therapy and is always directed by the treating physician or respiratory therapist — the device, technique and daily schedule are medical decisions. These devices are used as part of professional care, to complement it, and do not replace medical treatment (medications, enzyme replacement, physiotherapy, medical supervision) or remove the need for taught breathing techniques. OPEP should not be used in active febrile pneumonia, untreated pneumothorax, severe heart failure or when coughing up blood. In children with cystic fibrosis device use must be under medical prescription and supervision. If mucus colour or amount changes, or if fever, worsening breathlessness or coughing up blood occur, contact your treating physician without delay.

Frequently asked questions
The treating physician or respiratory therapist decides this based on the individual condition. In general, OPEP is the main device for mechanically mobilising thick secretions, and salt therapy can help loosen mucus as a supplement. Airway clearance for cystic fibrosis is always personalised and medically supervised — discuss device choice with your care team.
No. These devices are part of the complex treatment for cystic fibrosis and do not replace medications, enzyme replacement, physiotherapy or medical supervision. An airway clearance device is used together with taught breathing techniques under the guidance of the care team — it complements but does not substitute other therapy elements.
Airway clearance is especially important in children, but device use must be under the treating physician's prescription and supervision. OPEP requires a forced exhalation technique that very young children may not be able to perform — in such cases the respiratory therapist may recommend another method or training. The child's therapeutic protocol is always set by the care team.
This is determined by the individual condition and treatment plan, so your treating physician or respiratory therapist will advise. In cystic fibrosis regular daily clearance is often required, frequently multiple times a day — but the exact frequency, duration and technique are set by your care team for your situation.
If mucus colour (yellowish, greenish, brownish or bloody) or amount changes, if fever, worsening breathlessness or coughing up blood occur, or if your usual airway clearance is no longer effective. These may indicate infection or deterioration and need prompt medical evaluation. Close, regular contact with the care team is central to cystic fibrosis management.
