Asthma, chronic bronchitis and emphysema. The use of intermittent positive pressure breathing with inspiratory flow rate control. A review of the literature.
In chronic obstructive lung disease (asthma, chronic bronchitis, obstructive emphysema) there is a segmental reduction in the caliber of the airways, which always results in obstruction to air-flow. Increased airway resistance is a physiological expression of airway obstruction.The addition of inspiratory flow rate control to an intermittent positive pressure breathing device permits slow filling of a lung with obstructed airways, and is presented as a simple means of reducing the high pulmonary flow resistance and increasing the tidal volume.
