Quick Flashcards
Cat 1 triage
Unconscious, likely to die without immediate
Primary life threats
CV, resp, neuro, blocked cat
HyperK of UO and Addisons caues
Atrial standstill
PCV/TS for comp/decomp shock
Comp: hyperemic/
Expiratory effort, loud/harsh, crackles
lower airway (asthma, bronchitis)
Mixed insp/exp effort, harsh sounds/crackles, short/shallow
Parenchymal (contusion, hemorrhage, pneumonia)
Insp effort, short/shallow, quiet
Pleural dz (pneumothorax, pl eff)
Insp effort, stridor
Upper airway
Dog CO dop at
180 bpm
Vacular resistance formula
inversely proportional to radius to 4th powr
Worry about a cat when
Less than 160
Contractility decreases in
Sepsis, SIRS, heart dz
Treat contractility
Sepsis/SIRS- dobutamine
Heart dz- pimobendan
Fever anatomy
Ant hypothal
What determines body hydration
Na determines total body hydration
Dehy from, hypovol from
interstitial, intercellular; intravasc
Insensible losses
Sweat, saliva 20-30 mL/kg/day
5-7% dehy
CRT normal, tacky, mild tent
8-10% dehy
long CRT, tachy, poor pulse quality
Isotonic fluids
270-350
Bolus water IV
RBC swell from intracell shift (zero tonicity)
Maintenance characteristics
Low Na, Cl, higher K- NEVER bolus
Maint fluids
Norm M, PLyte 56
Replacement characteristics
Like plasma- high Na, Cl, low K; isotonic
Replacement fluids
NormR, PL148, 0.9 salline, LRS
Hypertonic fluids- contra
Dehydrated, hyperNa
Colloid function
Hold fluid in vasc space
Albumin portion of COP in health
80%
Gibbs Donnan effect
Charge is important, molecular weight does not effect osmolality (Na and Alb same contribution to osmolality without charge)
Alb contras
P who has had human, healthy- leads to anaphyl, delayed hypersens
Use for FFP
Clotting factors > colloid
Alb deficit
estimating anmount needed to increase alb conc to a desired level
Greater effect on coag- DS or molecular weight
DS
Effect of HES
interferes with vWF and factor VIII- platelet dysfunction
Monitor colloids
COP increases with HES concentration but TS no change, false increase in USG 2-3 hours post
Why CPR
Perfuse heart and brain
BPM in CPR
10-12 breaths, 100-120HR
Hyperventilation in CPR=
decreased CO leading to increased ischemia of coronary and cerebral
Open chest indications
pleural eff, pneumo, pericardial eff, chest trauma, DOA, too large- NOT abd wall problems
