Percantage of circulatory blood loss (136/1700)

A butcher stabbed accidently his groin. He bled so much that the towel was soaked in blood and
BP=80/50mmHg, pulse=130bpm. What % of circulatory blood did he lose?
a. <15%
b. 15-30%
c. 30-40%
d. 40-50%
e. >50%


























answer C
Classification:
1. Class 1 up to 15% of blood volume lost: pulse <100; systolic BP normal; pulse pressure normal; Respiratory rate 14-20; urine output greater than 30 ml/hour.
2. Class 2 15%-30% blood volume lost: pulse 100-120; systolic blood pressure normal; pulse pressure decreased; respiratory rate 20-30; urine output 20-30 ml/hour.
3. Class 3 30%-40% blood volume lost: pulse 120-140; systolic BP decreased; pulse pressure decreased, respiratory rate 30-40; urine output 5-15 ml/hr
4. Class 4, blood loss of greater than 40%: pulse rate >140; systolic BP decreased; pulse pressure decreased’ respiratory rate >35; urine output negligible.
