What is IPPB?
Intermittent positive pressure breathing (IPPB), a hyperinflation therapy modality, was one of the primary treatment modalities administered by inhalation therapists in the 1950s, 1960s, and 1970s.
IPPB is primarily prescribed to prevent atelectasis, to assist in clearance of secretions, and to deliver medications when other forms of therapy were unsuccessful.
IPPB delivers a prescribed gas at a positive pressure (usually 10-15 cm H20) for a specified time (usually 15 minutes.) Medications, such as bronchodilators, diluents, mucolytics, and antibiotics can be delivered via a nebulizer built into the breathing circuit. IPPB can be used on patients of all ages.
IPPB is most commonly delivered via a simple mouthpiece but flanged mouthpieces, shields/seals, oronasal masks, and 15 mm trach tube adapters can also be used, as applicable. Following the Sugarloaf Conference in 1974 where the scientific basis for IPPB was questioned, the use of IPPB significantly declined as other therapeutic techniques were substituted.
