    Intermittent positive pressure breathing (IPPB) is a mechanical ventilation method with limited clinical effectiveness for most pulmonary conditions. Its use is now restricted to specific cases of respiratory failure, severe bronchospasm, or refractory atelectasis.

    Area of Science:

    • Pulmonary Medicine
    • Respiratory Therapy
    • Critical Care

    Background:

    • Intermittent positive pressure breathing (IPPB) is a mechanical ventilation technique.
    • Historically used for various pulmonary conditions and medication delivery.
    • Recent clinical trials have questioned its widespread utility and effectiveness.

    Purpose of the Study:

    • To evaluate the clinical effectiveness of IPPB.
    • To determine the conditions where IPPB may still be beneficial.
    • To contrast IPPB with simpler therapeutic alternatives.

    Main Methods:

    • Review of published clinical trials and reports on IPPB.
    • Analysis of IPPB's efficacy in terms of morbidity, mortality, and lung function.
    • Comparison of IPPB outcomes with standard and simpler therapies.

    Main Results:

    • IPPB's effectiveness is short-lived (approx. 1 hour) with unproven long-term consequences.
    • No study has unequivocally demonstrated IPPB's clinical effectiveness.
    • IPPB offers no general advantage over simpler therapies for COPD, asthma, or atelectasis.

    Conclusions:

    • IPPB's widespread application has diminished due to questionable utility.
    • IPPB may be useful in specific patient groups: those at risk of respiratory failure (kyphoscoliosis, neuromuscular disorders), acute severe bronchospasm/COPD unresponsive to standard therapy, or refractory atelectasis.
    • Simpler therapies are generally preferred over IPPB for most pulmonary conditions.
