Influence of haemorrhage on the pseudo-steady-state remifentanil concentration in a swine model: a comparison with propofol and the effect of haemorrhagic shock stage  T. Kurita, M. Uraoka, K. Morita, M. Suzuki, Y. Morishima, S.

Fig 1 Individual plasma remifentanil and propofol concentrations before and during stepwise haemorrhage. The dotted line in each plot represents the concentration beyond the individual maximum SVR (uncompensated shock).

Fig 2 Relationship between cumulative blood loss (% estimated initial blood volume) and % increases from the prehaemorrhage plasma concentration. The linear regression lines for each relationship were evaluated for data collected at less than (compensated shock) or beyond (uncompensated shock) the individual maximum SVR.

Fig 3 Relationships between plasma remifentanil or propofol concentrations and the reciprocal of CO. The linear regression lines for each relationship were evaluated for data collected at less than (compensated shock) and beyond (uncompensated shock) the individual maximum SVR.
