Brief Summary:
finding surrogate to co to trace the effect of preload challenge would make the test more applicable without the need of advanced hemodynamic monitors,suggested that co2 gap can be used to detect FR after mini fluid challenge and fluid bolts .

Condition or disease Intervention/treatment Phase
Liver Transplantation Diagnostic Test: Fluid challenge Not Applicable

Detailed Description:

use of carbon dioxide gap and arterio venous oxygen content to trace the effect of preload challenge by giving via a specific venous line , first 150 ml is infused over one minute, after stroke volume at one minute measure the remaining 350 ml is infused over 14 minutes at constant rate , the fluid challenge performed with albumin 5% , fluid responsiveness is an increase in stroke volume by 15% after infusion of 500ml albumin 5%.

Objectives is to investigate the ability of VA-co2 gap and gap/ ratio to predict the hemodynamic response to mini fluid challenge, and to compare the validity of VA-co2 gap and gap/ratio with svo2 for prediction of fluid responsiveness.

Arm Intervention/treatment
Experimental: CO2 gap
The patients will receive fluid bolus and observe changes in co2 gap and gap/ ratio in them.
Diagnostic Test: Fluid challenge
Fluid challenge and measure change in co2 gap

Primary Outcome Measures :
  1. co2gap [ Time Frame: 30 minuets after fluid bolus ]
    Difference between arterial and venous co2 gap

Secondary Outcome Measures :
  1. Stroke volume [ Time Frame: Baseline 30 minutes after Icu admission, 1 minutes after mini fluid challenge , 30 minutes after fluid bolus ]
    Stroke volume assessed by cardiometry
