Twenty patients with cystic fibrosis (CF) were trained to mobilize intrabronchial secretions by a new method of positive expiratory pressure mask (PEP mask) physiotherapy (PT). Patients repeatedly expired forcefully through the PEP mask; expiratory resistance was varied by eight different internal diameter resistors at the outlet. Forced vital capacity with the mask (FVCPEP) was determined for each resistor and was compared with the one measured without the instrument (FVC); simultaneously the…

Positive expiratory pressure physiotherapy for airway clearance in people with cystic fibrosis.
TLDR
The effectiveness and acceptability of PEP devices compared to other forms of physiotherapy as a means of improving mucus clearance and other outcomes in people with CF is determined.
Non-invasive ventilation assists chest physiotherapy in adults with acute exacerbations of cystic fibrosis
TLDR
Reduced inspiratory muscle strength and oxygen desaturation during chest physiotherapy are associated with inspiratory Muscle weakness and severity of lung disease in adults with exacerbations of CF.
Non‐invasive Ventilation as Airway Clearance Technique in Cystic Fibrosis
TLDR
Non-invasive ventilation was shown to be a good alternative to PEP in chest physiotherapy for patients with cystic fibrosis who are severely ill and there was a significant reduction in lung clearance index (LCI) following NIV compared with PEP.
Cystic fibrosis: comparison between conventional chest physical therapy and positive expiratory pressure in hospitalized patients
TLDR
There were no statistically significant differences between the two groups with respect to outcome in the treatment of cystic fibrosis patients during hospital treatment of exacerbation and PEP gives more autonomy to the patients.
Physiologic evidence for the efficacy of positive expiratory pressure as an airway clearance technique in patients with cystic fibrosis.
TLDR
Low PEP and high PEP improve gas mixing in individuals with CF, and these improvements were associated with increased lung function, sputum expectoration, and SpO(2).
Positive expiratory pressure physiotherapy for airway clearance in people with cystic fibrosis.
TLDR
The effectiveness and acceptability of PEP devices compared to other forms of physiotherapy as a means of improving mucus clearance and other outcomes in people with cystic fibrosis were determined and there was a significant reduction in pulmonary exacerbations in people using PEP.
Self-administered chest physiotherapy in cystic fibrosis: A comparative study of high-pressure pep and autogenic drainage
TLDR
Patients with cystic fibrosis were trained in 2 self-administered chest physiotherapy techniques: high-pressure PEP-mask physiotherapy (PEP), and autogenic drainage (AD); patients with airway hyperreactivity should either prefer AD or take a bronchodilator premedication before PEP.
Positive expiratory pressure techniques in respiratory patients: old evidence and new insights
TLDR
The rationale for the use of positive expiratory pressure (PEP) techniques as a means of chest physiotherapy in respiratory patients is discussed and both the effectiveness and problems of the most popular PEP devices in clinical practice are compared.
Chest physiotherapy in hospitalized patients with cystic fibrosis: a study of lung function effects and sputum production.
TLDR
High-pressure PEP-mask PT resulted in significant lung function improvements, and not only maintained but increased its effect in the course of the hospitalization.
Effect of positive expiratory pressure breathing in patients with cystic fibrosis.
TLDR
In patients with cystic fibrosis positive expiratory pressure breathing increases lung volumes in relation to the expiratories pressure imposed; these changes in lung volume did not, however, lead to an improvement of mucus transport.

Evaluation of the forced expiration technique as an adjunct to postural drainage in treatment of cystic fibrosis.
TLDR
Patients with cystic fibrosis who have had to rely on the help of others for their home treatment may now perform more effective treatment without help, thanks to the forced expiration technique.
Bronchodilators increase airway instability in cystic fibrosis.
TLDR
In 18 children with cystic fibrosis, routine pulmonary functions and VACMEFV were measured before and after bronchodilator medication, significantly improving FVC, FEV1, FEF25-75, VC, PEF, Raw, and also VACmeFV, which correlated directly with the curvilinearity of the flow-volume curve and inversely with the clinical and radiologic score.

Cystic fibrosis: physical exercise versus chest physiotherapy.
TLDR
Regular physical exercise could replace the inhalation-physiotherapy routine in some children with cystic fibrosis and indicate improvement of airways function plus some ventilatory muscle training.

TLDR

Significance of the relationship between lung recoil and maximum expiratory flow.
TLDR
A theoretical relationship between the static recoil of lungs and the maximum rate at which gas can be expelled from them is developed and the configuration of maximum expiratory flow-volume curves are found.

The site of airway obstruction in cystic fibrosis.
TLDR
Differences in the extent to which measurements of airway resistance and distribution of ventilation are altered in patients with cystic fibrosis may be used to localize the site of obstruction and to follow the different stages in the natural history of the pulmonary disease.
