CHAPTER 1 - HEMOSTASIS Flashcards
purplish red, pinpoint hemorrhagic spots in the skin
Petechiae
caused by loss of capillary ability to withstand normal blood pressure and trauma.
Petechiae
1-2 mm
Petechiae
cause: rupture of weak capillary (due to genetics, thrombocytopenia (low plt ct))
Petechiae
non-blanching (Diff to rash) or non-palpable
Petechiae
produced by hemorrhage of blood into small areas of skin, mucous membranes, and other tissues
Purpura
First appears red-purple the turns brownish yellow
Purpura
> or = 3 mm
Purpura
Bigger than Petechiae
Purpura
Coalesced Petechiae (united)
Purpura
small areas of the skin and mm, and other tissues
Purpura
cause: bleeding under the skin (hemmorhage)
Purpura
Purpura types:
(exists on the kin)
(from the skin, deeper to mm)
more significat
dry type
wet type
wet type
appears like hemmorhagic blisters
Purpura
indicates thrombocytopenia)
Purpura
non-blanching or palpable
Purpura
a form of purpura in which blood escapes into large areas of skin or mucous membranes, but not into deep tissue.
Ecchymosis
Appears Black/blue then turns greenish brown to yellow
Ecchymosis
> 1-2 cms
Ecchymosis
bruising on large areas of the skin (subcutaneous accumulation of blood)
Ecchymosis
difference in color is caused by breakdown of Hb to biliverdin to bilirubiin
Ecchymosis
Cause: on going coagulation or damage to the blood
Ecchymosis
Nosebleed
Epistaxis
One of the symptoms of vascular fragility
Epistaxis
low plt ct or genetic cause
Epistaxis
Petechiae
significance: vasc fragility (hema)
Epistaxis
leakage of blood into a joint cavity
Hemarthrosis (-ses for plural)
Cause: trauma
Hemarthrosis (-ses for plural)
attributed to bleeding disorders ex: Hemophilia, any other casesw/ cog factor deficiency
Hemarthrosis (-ses for plural)
vomiting of blood
Hematemesis
Cause: ulceration in the GIT
Hematemesis
vomiting from GI
Hematemesis
happens when blood vessels does not close
Hematemesis
Hematemesis 3 components:
o BV
o CF
o Plt
expectoration of blood secondary to hemorrhage in the larynx, trachea, bronchi or lungs
Hemoptysis
Spitting of blood from the respiratory system
Hemoptysis
a swelling or tumor in the tissues or a body cavity that contains clotted blood
Hematoma
> 2-3 cm
Hematoma
solid clot causing swelling under skin
Hematoma
cause: broken blood vessels and bleeding disorders
Hematoma
hard and painful
Hematoma
