Aarc Guideline: Intermittent Positive Pressure Breathing

چکیده
IPPB 2.0 DESCRIPTION/DEFINITION: The first American Association for Respiratory Care (AARC) clinical practice guideline (CPG) for Intermittent Positive Pressure Breathing (IPPB) was published in 1993. Since that time there have been additional studies, systematic overviews, and a meta-analysis that specifically addresses the eff icacy of IPPB as compared to other hyperinflation and aerosol delivery techniques.1 Those studies have been added as references to this revised CPG. IPPB remains a technique used to provide shortterm or intermittent mechanical ventilation for the purpose of augmenting lung expansion, delivering aerosol medication, or assisting ventilation.2 A caveat, however, is that IPPB is not the therapy of first choice for delivering aerosol or as a method of lung hyperinflation in spontaneously breathing patients when other less expensive therapies can reliably meet the clinical objectives prescribed for the p a t i e n t .1 , 3 1 2 It should be noted that noninvasive positive pressure ventilation (NPPV) may be considered as a form of IPPB to assist ventilation, although a review of this therapeutic modality was not included in this CPG. 2 . 1 IPPB can include pressureand time-limited, as well as pressure, time, and flow-cycled ventilation. 2.2 IPPB may be delivered to artificial airways and nonintubated patients.

Intermittent positive-pressure breathing after lung surgery.
Intermittent positive-pressure breathing is thought to avoid atelectasis and improve pulmonary function after major lung resections. Since no clear scientific data was available to confirm this, our objective was to determine whether atelectasis can be avoided and if postoperative lung function is improved. Prospective analysis was carried out in 135 patients operated on between 2007 and 2009; ...
متن کاملThe use of positive pressure devices by physiotherapists.
The aim of this paper is to review the indications for use by physiotherapists, such as physiological rationale and the comparative efficacy of intermittent positive pressure breathing (IPPB) and continuous positive airway pressure (CPAP). A brief discussion of nasal intermittent positive airway pressure is also included. The use of IPPB for post operative prophylaxis has not been supported in ...
متن کاملPhysiological studies of the effects of intermittent positive pressure breathing on cardiac output in man.
Three types of positive pressure breathing have been differentiated : a) continuous positive pressure breathing where a pressure above atmospheric is maintained in the lungs throughout the respiratory cycle, b) expiratory positive pressure breathing in which a pressure above atmospheric is present during the expiratory phase of breathing, and c) intermittent positive pressure breathing (IPPB), ...
متن کاملComparison of salbutamol given by intermittent positive-pressure breathing and pressure-packed aerosol in chronic asthma.
A double-blind crossover study was performed to compare 4 . 8 mg salbutamol given by pressure-packed aerosol and intermittent positive-pressure breathing nebulization in chronic asthmatic patients. The two delivery techniques produced similar changes in respiratory function and pulse rates. Given equal effect, a high-dose pressure-packed aerosol would have advantages in cost and convenience ove...
