On CPB, the flow through the manifold samples line was severely restricted. It was noticed during administration through the line as it was easy to see clear fluid flowing extremely slowly along the line.
Also, the temperature read by the CDI monitoring was affected, with readings of around 6degrees Celsius lower than the actual one, with effects on pH stat values.
By removing the one way valve, all issues were resolved promptly.
