OBJECTIVE: To improve post operative atelectasis with Coronary Artery Bypass Graft patients as determined by chest X-ray. Also further compare the results of EzPAP therapy with Incentive Spirometry.

DESCRIPTION: EzPAP from DHD Healthcare combines patient negative pressure breathing and all of its benefits, with a positive expiratory pressure. Using a fluidic process, flow is augmented on inspiration. PEP is provided during expiration. This augmentation provides for a larger flow and volume with less effort than an unsupported inspiration.

DESIGN, SETTING, AND PARTICIPANTS: A study was conducted from August 2001 to October 2001 on 50 patients that were randomly selected to have either EzPAP or Incentive Spirometry after post op Coronary Artery Bypass Graft Surgery.

MEASURES: Chest radiograph was read by radiologist. Atelectasis on chest X-ray were reviewed and compared on postoperative day of surgery and after chest tubes removed.

Results: The Incentive Spirometry group (n=20) showed improved atelectasis 25% vs. EzPAP group (n=30) showed improvement of atelectasis 100%. This improvement was statistically significant (p<.001).

CONCLUSION: EzPAP therapy has demonstrated measurable improvements in atelectatic post surgical Coronary Artery Bypass Graft patients, and should be considered a viable option in the pulmonary management of this population.
