Extracellular haemoglobin (Hb) in pre, mid & post warmed RC warmed with latent heat or the dry heat blood warmer (n = 67). LH pre = Latent heat prototype, sample extracted from inlet line (before warming). LH mid = Latent heat prototype, sample extracted from outlet line midway through RC unit (warmed). LH post = Latent heat prototype, sample extracted from outlet line at the end of the RC unit (warmed). DH pre = Dry heat blood warmer, sample extracted from inlet line (before warming). DH mid = Dry heat blood warmer, sample extracted from outlet line midway through RC unit (warmed). DH post = Dry heat blood warmer, sample extracted from outlet line at the end of the red RC (warmed).
