Question | Answer |
---|---|
Natural hemostasis | Clot formation or vessel spasm |
Artificial hemostasis | Compression or ligation |
Four factors for hemostasis to occur | Adequate numbers of platelets Platelet normal function Vascular integrity All coagulation factors present |
Coagulation | Formation of a clot |
Number of clotting factors | 13 |
Clotting factors are... | proteins |
Intrinsic pathway is located | intravascular system |
Extrinsic pathway occurs | Tissue system |
The key to the clotting mechanism | Thrombin |
Factor VIII | von Willebrands |
Factor I | Fibrinogen |
Factor II | Prothrombin |
Qualitative | pertaining to observations of a categorical nature |
Quantitative | pertaining to observations of a numerical nature |
Coagulopathy | Any disorder of blood coagulation |
Tubes that "tie up"/bind calcium to prevent the coagulation cascade | Btt-Sodium Citrate & Ltt- EDTA |
Blood to anticoagulant ratio | 9:1 |
EDTA/LTT tube for | Platelet counts |
BTT/Sodium Citrate | Coagulation testing/Evaluation of intrinsic and extrinsic pathways |
Platelet Poor Plasma | Coagulation testing |
Platelet Rich Plasma | Platelet Function Testing |
Whole Blood Clotting Time is also called the | Lee-White method |
Activated Clotting Time | Intrinsic clotting mechanism |
ACT activating agent: | Diatomaceous Earth |
ACT normal value | 60-90seconds |
Buccal Mucosa Bleeding Time (normal time) | 1-5min. (1-3) |
BMBT prolonged with | platelet defects, increased capillarity fragility, Von Willebrands |
OSPT normal range | 7-10 seconds |
