Figure 6.

Fetal mean arterial blood pressure (left) and heart rate (right) in response to (from top to bottom) pericardial saline or procaine injection in normovolaemic fetuses and responses to slow haemorrhage in fetuses treated with pericardial saline (n = 7 fetuses were treated with saline, both with and without haemorrhage) or procaine (n = 11 fetuses were treated with procaine, both with and without haemorrhage). Data are represented as mean values with vertical bars representing 1 standard error above and below the mean.
