To compare the efficacy between flow and volume oriented incentive spirometry (IS) after upper abdominal surgery using PFT studies. To determine the effectiveness of spirometer use after abdominal surgeries to prevent post operative pulmonary complications

Experimental study design was adopted for the study.

40(20 in group 1 and 20 in group 2) patients from male surgery ward who had planned for upper abdominal surgery ware randomly selected. Selection of these patients ware based on inclusion criteria.

Systemic Random sampling method is used

40 patients from male surgery ward who had planned for upper abdominal surgery ware randomly selected. Before investigation of IS post operative parameters of FVC, IC, and MVV was investigated for any restrictive condition.

Group1 (flow oriented spirometer):20 subjects were selected in this group. Subject was taught pre operatively the use of this type of IS.

Group 2 (Volume oriented spirometry):20 subjects were selected in this group. They were given a volume spirometer (Voldyne spirometer

Follow up of the patient under study: The PFT values for improvement of the parameters of FVC, IC and MVV was taken on day, 15th day, 1st month and 2^nd month.

Siprometer investigation foe FVC, IC and MVV was performed with patient in seated position using RMS medispiral PC based computer interfaced machine. Pulmonary values were based on effort (best of three). They were done preoperatively and post operatively on intervals of 15^th day, 1st month and 2^nd month respectively.

There is no significant difference between volume and flow oriented spirometry in the mean values of FVC and highly significant difference in IC and MVV.

Different types of incentive spirometer differ considerably in their post operative performance. These difference seen to be clinically relevant because of their impact on post operative incentive spirometer performance. The volume oriented Incentive spirometry allows improved maximal sustained inspiration and therefore might be more suitable for post operative respiratory muscle training.
