    So, asthma causes wheezing which causes a greater expiratory effort which 'increases intrapleural pressure, compressing small intrathoracic airways further and limits expiratory flow'.
    Could anyone explain why the greater expiratory effort increases intrapleural pressure? Is it related to greater expiratory pressure needing the use of abdominal muscles?

    Your airways are narrow so you need to push harder to get air out, hence the pressure increase.

    Your abdominal are your main muscles of exhalation yes.
