Battaglia/Steele Flashcards
3 types of monitoring in E/CC setting
hands-on, clinicopathologic, device-based
PE includes
inspection, palpation, auscultation, percussion, olfaction, temperature
abdominal palpation
1: cranial-dorsal
2: cranial-ventral
3: mid-dorsal
4: mid-ventral
5: caudal-dorsal
6: caudal-ventral
pulse pressure
systolic-diastolic
pulse deficit
heart isn’t able to pump enough blood
EX: DCM, a-fib, premature arrhythmias
bounding pulses
compensatory shock
weak/thready pulses
poor cardiac output, hypovolemia, tachycardia, arrhythmias
how to use a stethoscope
bell: light contact - low frequency
diaphragm: firm contact - high frequency
percussion
air: hollow
fluid:: dull/flat
maximum amount of blood to draw per week
5 - 7% blood volume (Casal & Bentz, 2018)
rate of glucose metabolism per hour when plasma remains in contact with rbcs
5-10% per hour
cause of lipemic samples
recent meal
panc
DM
hypothyroid
lipid disorders
cause of icteric samples
liver disease or hemolytic anemia
cause of hemolysis
poro sampling technique
IV hemolysis (hemolytic anemia)
MCV
mean corpuscular volume: volume of the average RBC
role of plasma proteins
transportation, coagulation, immune protection, oncotic pressure
interpret the following with high PCV
normal TS
low TS
high TS
-splenic contraction/breed normal
protein loss or decreased RBC production with splenic contraction and dehydration (AHDS)
dehydration
interpret the following with low PCV
normal TS
low TS
high TS
anemia from RBC destruction or dec production
blood loss or dilution
protein over production and anemia (bone marrow diseases, FIP)
interpret the following with normal PCV
low TS
high TS
decreased protein production or loss from GIT/Urinary
dehydration + anemia or increased globulin production (FiP/infectious dx)
perform a blood smear evaluation
low power scan: clumping at feathered edge
x40: monolayer: estimate WBC (1 field x 1600)
x100: platelet count (x 15000)
determine venous vs arterial stick
PCO2: venous»_space; arterial
PO2: venous «_space;arterial
PaO2
how well blood is oxygenating, how well lungs and pulmonary circulation are functioning
PaCO2
indicator of ventilation
HCO3
major buffer
BE
amount of base above or below the normal buffer level
Base deficit (neg) how many units of base are needed to return to neutral
base excess (pos)
steps of a blood gas
1) pH
2) HCO3/BE
3) PaCO2
expected aO2
5x FiO2
PaOO2 < 60 - 80 mmHg
mild to severe hypoxmia
COP
colloid osmotic pressure
Type A lactic acidosis
tissue hypoxia, poor perfusion, shock
Type B lactic acidosis
1) systemic illness
2) drugs/toxins
3) hereditary
4) misc.
Coagulation tests
ACT
BMBT
manual platelet counts
PT/aPTT
Primary hemostasis
relates to platelet or vessel dissorders
measured by BMBT and plt count
ex: VWd, thrombocytopenia, thrombocytopathia, vasculopathies
platelet adhesion, activation, aggregation
secondary hemostasis
coagulation cascade
Pulse oximeter
transmittance type (clip)
reflectance type
92% = PaO2 60 mmHg
Blood Pressure
direct
oscillometric
doppler: 1st systolic, change diastolic
calculate MAP
DP + (SP-DP)/3
EtCO2
alternative to PaCO2 (blood gas) and about 5mm less than arterial
CVP
BP w/in R atrium (cranial or caudal VC)to assess for hopovolemia or at risk of volume overload
normal: 0-10 cm H2O
hypovolemia <normal
goal placement of CVC
mid jugular to second rib space: cranial to right atrium
hydration deficit formula
volume (mL) = dehydration (decimal) x kg x 1000
maintenence fluid requirementrange
40-60 ml/kg/day
storage lesions in blood produccts
no mitochondria = glycolosis for ATP production = lower pH
imapired RBC survival
reduced O2 carrying
proinflammatory and oxidative damage
major XM
patient plasma, donor RBC
minor XM
patient RBC, donor plasma
dose of PPRBC
10mLkg
dose of WB
20mL/kg
RBC dosing formula is known as PCV
90mL x (kg) x (goal PCV - patient PCV) / PCV
RBC dosing formula, PCV 80%
2mL x PCV inc. x BW
RBC dosing formula, PCV 60%
1.5ml x PCV inc. x BW
WB dosing formula, PCV 45%
1ml x PCV inc. x BW
blood filter size
170 - 260 micrometers
Allergic reactions
Type 1 hypersensitivity (igE on mast cells degranulate and release histamine and leuktrienes)
What does SBAR stand for?
SBAR stands for Situation, Background, Assessment, Recommendation.
What does I-PASS stand for?
I-PASS stands for Introduction, Patient summary, Action list, Situation awareness/contingency planning, synthesis by receiver.
