Background- Arterial blood gas (ABg) is the gold standard for blood gas analysis. in asthma exacerbation severity evaluation,
ABg is important; however, it is somehow difficult and potentially dangerous. Using venous blood gas (VBg) sampling is easier for
less expert personnel, with minimal damage for patient. in this research, we want to compare aBg & VBg indexes in asthma
exacerbation.
method-this prospective diagnostic study was done with convenience sampling of 50 admitted children, 36 boys and 14 girls,
between 3 and 6 years (mean 4.18) in pediatric emergency ward in shariati hospital in isfahan with asthma exacerbation during
2009 spring. they were normotensive and their temperature between 36-38.5. ABg sampling as routine in asthma management
and VBg sampling along other venous tests were done without any excessive cost for patient. For both ABg and VBg test, we used
an AVl compact1 analyzer few minutes after sampling. For data analysis, we utilized sPss ver. 14.
results-From 17 patient with PO < 60 in ABg, 100% had PO 60, 80.77% had PO >60 in VBg

and for seven with normal PO in ABg 57.14% had normal value in VBg. For relationship between PO in ABg and VBg P-value was

From nine patients with PCO > 45 in ABg, 66.67% had PCO >45 in VBg.For 22 patients with PCO
