Estimation of lung vital capacity before and after coronary artery bypass grafting surgery: a comparison of incentive spirometer and ventilometry

Table 2 Comparison with averages and Standard deviation variables: age, BMI, DVC through ventilometry and spirometry in pre and post operatory groups

VARIABLES	PRE OPERATORY AVERAGE ± SD	POST OPERATORY AVERAGE ± SD	p
Age	49.7 ± 15.13 years	49.7 ± 15.8 years	0.985
BMI	24.8 ± 3.3 kg/m ²	25.5 ± 2.5 kg/m ²	0.353
DVCV	32.95 ± 11.4 ml/Kg	28.27 ± 12.48 ml/Kg	0.304
DVCI	28.9 ± 11 ml/Kg	26.98 ± 11 ml/Kg	0.859

BMI: Body mass index, DVCV: direct vital capacity measured with ventilometer. DVCI: direct vital capacity measured with incentive inspirometer.
