Effect of positive expiratory pressure breathing in patients with cystic fibrosis.
The effect of positive expiratory pressure breathing, alone and in combination with coughing, was investigated in eight patients with cystic fibrosis. Functional residual capacity and total lung capacity was measured with a body plethysmograph before, during, and immediately after breathing with expiratory pressure of 5 and 15 cm H2O, and after a coughing period. The positive expiratory pressur...
متن کاملPositive Expiratory Pressure (PEP) versus Conventional Chest Physiotherapy in Pediatric Patients with Acute Exacerbation of Cystic Fibrosis
Background Pulmonary involvement is the main cause of mortality in cystic fibrosis (CF). Airway clearance techniques are non-pharmacological complement options for CF patients. The aim of this study was to evaluate the short-term outcome of airway cleaning treatment in patients with cystic fibrosis in a children's hospital. Materials and Methods This clinical trial study conducted on 40 CF pati...
متن کاملPositive expiratory pressure changes aerosol distribution in patients with cystic fibrosis.
HYPOTHESIS We hypothesized that aerosol distribution in the lungs of patients with cystic fibrosis changes with positive expiratory pressure (PEP). METHODS Eight patients were randomized to one of 2 conditions. On one study day, patients inhaled saline aerosol containing 99mtechnetium generated by a Pari LC Plus nebulizer and exhaled through a Pari PEP device. On another day, the same patient...
متن کاملPhysiologic evidence for high-frequency chest wall oscillation and positive expiratory pressure breathing in hospitalized subjects with cystic fibrosis.
BACKGROUND AND PURPOSE This investigation identified ventilation distribution, gas mixing, lung function, and arterial blood oxyhemoglobin saturation (SpO2) physiologic responses to 2 independent airway clearance treatments, high-frequency chest wall oscillation (HFCWO) and low positive expiratory pressure (PEP) breathing, for subjects who had cystic fibrosis (CF) and who were hospitalized duri...
متن کاملImmediate changes in blood-gas tensions during chest physiotherapy with positive expiratory pressure and oscillating positive expiratory pressure in patients with cystic fibrosis.
OBJECTIVE To assess and compare immediate effects of chest physiotherapy with positive expiratory pressure (PEP) versus oscillating PEP on transcutaneously measured blood-gas tensions in patients with cystic fibrosis. METHODS Fifteen patients (mean age 12.5 y, range 6.9-21.5 y) participated. The treatments were randomized and performed on 2 separate occasions, 8 weeks apart. Spirometry was co...
