Comparing the Inspiratory Capacity Measurements Obtained by Incentive Spirometry and Ultrasonic Spirography in the Early Postoperative Period in Cardiac Surgery Patients

Incentive spirometry is one of the most common methods used for respiratory rehabilitation in early period after cardiac surgery. Inspiratory capacity values, obtained by a patient using spirometer, are not reliably trusted. Objectives. To compare volumetric parameters measured with incentive spirometer and results bedside ultrasound-based to assure feasibility use assess inspiratory e?ectiveness postoperative rehabilitation. Materials methods. The study included 50 patients elective Pulmonary involved various therapy Spirography was performed before each session. Both approaches were simultaneously obtain maximum (SMIC) ultrasonic spirography (MIC) index an spirometer. Patient’s discomfort adverse events during procedures recorded. Results. absolute values MIC session two dissimilar, however, average increment (6) did show statistically significant differences. correlation analysis revealed strong positive relationship between 6 SMIC ( R = 0.74 session, 0.79 0.77 across whole data set, P < 0.01), also consistent Bland–Altman analysis, evidencing that more than 95% all fell within ± 1.96 SD mean difference. method showed good diagnostic accuracy (sensitivity 87%, specificity 85%, area under curve (AUC) 0.8 (95% CI: [0.76; 0.83]), 0.001). Refusals procedure often documented spirography. Conclusion. shows agreement measurements. Therefore, can be effectiveness interventions surgery period.
