  1. 1. Resistance breathing with PEP and CPAP : effects on respiratory parameters

    Författare :Maria Sehlin; Ola Winsö; Karin Wadell; Fredrik Öhberg; Monika Fagevik Olsèn; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chest physiotherapy; breathing exercises; PEP; CPAP; airway pressure; airflow; threshold resistor; flow resistor; inspiratory capacity; Borg CR10;

    Sammanfattning : Background: Positive expiratory pressure (PEP) and continuous positive airway pressure (CPAP) are two forms of resistance breathing used in spontaneously breathing patients. With a threshold resistor or a flow resistor, both PEP and CPAP provide a positive (elevated) pressure level during the expiratory phase. LÄS MER
