BACKGROUND-EzPAP is an option for treating and preventing atelectasis. It provides positive pressure that amplies an input ow of either air or oxygen approximately 4 times and this auguementation provides a larger ow with less effort than an unsupported inspiration and PEEP provided on expiration.So it clear secrections,increase lung volume and improve gas exchange.It provides positive pressure therapy independent of patient efforts;thus improve lung functions.EzPAP is an easily implemented ,disposable device that delievers continous positive airway pressure using ow from an oxygen ow meter via a mouthpiece or facemask .It provides a costeffective and easily utilized form of CPAP. OBJECTIVE-This study was carried out to compare the effects of EzPAP therapy on pulmonary function test after abdominal surgeries under general anaesthesia for more than 3 hrs and compare the postoperative volumetric spirometric values FVC,PEFR,FEV with preoperative baseline values. 1 Method-we conducted a prospective interventional study in 35 ASA I and II patients posted for elective abdominal surgeries .Various parameters such as age ,sex,surgeries ,time for surgery ,pulmonary spirometric values FVC,PEFR,FEV at preoperative 1 24 hrs and postoperative 48 hrs are noted.Quantitative analysis done. RESULTS-In this selected group of patients who are taken EzPAP therapy difference between preoperative and postoperative lung volumes was higher in postoperative conditions for parameters FVC,PEFR,FEV after EzPAP therapy.Medway NHS 1 foundation trust department based clinical study in their study ,EzPAP in relation to increasing or maintaining lung volumes and results in improvement in all physiological parameters. CONCLUSION- This prospective interventional study suggests that;EZPAP positive airway pressure device is a useful to improve respiratory functions and clinical improvements in lung volumes in the post operative patients undergoing general anaesthesia for more than 2 hrs , preventing atelectasis and postoperative hypoxemia . |
