Ain-Shams Journal of Anesthesiology

Table 3 Comparison between responders and non-responders regarding cardiac output (CO) values of the studied patients

		Responders	Non-responders	Test value^a	P value	Sig.
		No.= 29	No.= 29	Test value^a	P value	Sig.
CO (baseline)	Mean ± SD	4.70 ± 0.26	4.75 ± 0.23	− 0.796	0.430	NS
CO (baseline)	Range	4–5	4.3–5.1	− 0.796	0.430	NS
CO (after volume expansion)	Mean ± SD	5.36 ± 0.21	4.83 ± 0.22	9.295	< 0.001	HS
CO (after volume expansion)	Range	4.9–5.6	4.5–5.3	9.295	< 0.001	HS

P value > 0.05: nonsignificant (NS); P value < 0.05: significant (S); P value < 0.01: highly significant (HS)
CO: cardiac output (L/min)
