Hematic auto-management and extraction for arterial line (HAMEL), a blood-preserving arterial line system: an animal study

According to the study design, the estimated amount of blood loss per one experiment was at least 115 mL (For first sub-experiment; 45 mL, 11 blood samples, for second sub-experiment; 70 mL, 20 blood samples) plus 30 mL (for additional blood sampling due to the test errors). Estimated time spent for all procedures (sedation and intubation of pig, first and second sub-experiment) was at least 3 h. We could afford only one experiment per one pig for this reason, and as we planned to obtain 50 blood samples for each of first and second sub-experiment, we used a total of five pigs for…
