So I donated blood immediately before a Jujutsu class. Did okay in general, but felt myself fading out a couple times, like if you stand up too quickly on a hot day sometimes. Once I would have keeled over if I hadn't paused and taken a knee. Anyway, thought it was an interesting experiment. |

You donated more than one unit of blood? One unit is not "significant" blood loss. |

Anyway, thought it was an interesting experiment. I made the mistake once in working out after giving blood. I was doing my warmup on the bike when field of vision started shrinking to a narrow tunnel. I made it off the bike and sitting against the wall before vision shrunk to a pinhole. I didn't pass out, but it was a few minutes before I could stand again. |

I have seen the resulting puddle of blood where a man was shot dead lying on a tile floor. Of course it was not all of the blood in him, as at some point his heart stopped pumping after being shot six times. It was a significant size puddle! |

I say loosing 10% of your blood IS significant and thank you for your observations Rodent. I'm sure loosing 20-30% is even more significant and have heard that after loosing 3 units it's pretty tough going. |

Donor performance of combat readiness skills of special forces soldiers are maintained immediately after whole blood donation: a study to support the development of a prehospital fresh whole blood transfusion program Study design and methods: Twenty-five fit male soldiers from a special forces unit were divided into three groups and tested on 1) a Bruce protocol treadmill stress test, push-ups, and pull-ups; 2) a 50-round rapid pistol shooting test; and 3) an uphill hiking exercise carrying a 20-kg backpack. After baseline testing, the soldiers performed the tests again (2-6 min) after donating 450 mL of blood. The training program included blood collection and reinfusion procedures and we measured success rate of venipuncture, time for blood collection, and success in placing sternal intraosseous needle and reinfusing 1 unit of autologous blood. Results: We did not find any significant decrease in performance either in physical or in shooting performance after donating blood. Nonmedic soldiers had a 100% success rate in blood collection and also infusion on fellow soldiers after a short introduction to the procedures. Conclusion: This study supports the fact that buddy transfusion may be feasible for healthy well-trained soldiers and does not decrease donor combat performance under ideal circumstances. Since not everybody is a fit male solider from a special forces unit I think knowing your personal limits and capabilities is a useful thing |
