TEMPORARY HEMOSTAIS
- tourniquet
- elastic compression
permanenet hemostasis
vesse ligation
tourinquet
it limits NOT STOPS the flow of blood
during surgeries what things can contrinute to bleedingj
preocedural factors
what does extrinsic pathway begin with
7
what does intrisic begin with
12
what is the common agent in both pathways
10
