Comparison and agreement between arterial versus venous blood gas analysis and pulse oxymetry in children with acute asthma

Background: Blood gas analysis is critical in managing children intensive care unit primarily respiratory disorders. This study aimed to ascertain agreement between the arterial and peripheral venous measurement of pH, pCO2, pO2 bicarbonate levels along with SpO2 acute asthma.Methods: Hospital based cross sectional analytical was conducted at Pushpagiri Institute Medical Sciences 50 within age group 5-15 years who presented symptoms suggestive asthma a modified PSI>6 after informed consent from parents assent child. monitoring ABG simultaneously VBG were done immediately admission. Statistical find out any correlation using Pearson coefficient Bland Altman plots drawn assess agreement.Results: 5 15 included study. Arterial pH found be correlated significantly, r=0.438. There good pCO2 r= 0.610, values r=0.608. poor PO2 (r=0.030). The bias plot for showed moderate 95% limits being acceptably narrow range. mean 0.0242 (SD=0.04912, = -0.0721 0.12045); -4.04400 (SD=5.53616, -14.8949 6.8069), -0.0940 (SD=2.09, -4.1998 4.0119).Conclusions: Even though there parameters like bicarbonate, cannot replaced asthma. Pulse oximetry also has limitations severe as compared value.
