⩥ MRI Suite Safety.
Answer: Zone 1 = public access, no supervision = hallway outside of
MRI suite
Zone 2 = public access, minimal supervision = entrance to MRI suite
Zone 3 = limited access, strict supervision = MRI control room
Zone 4 = very limited access, very strict supervision = MRI scanner
room
safe metals = stainless steel, titanium, aluminum, copper
- make sure pt doesn't have pacemaker, ICD, aneurysm clip, metal
implant, implantable pump, shrapnel
- EKG = might have T wave + ST segment artifact
- MRI safe cylinders = silver with color code on top
,⩥ Aldrete Score.
Answer: - quantifies readiness for discharge from PACU
- score 9 or higher suggests readiness for discharge
- PONV not assessed
- Activity = 0>> cannot move head or extremities, 1 >> moves 2
extremities voluntarily + lift head 2 >> moves all extremities + can lift
head
- Respiration = 0 >> apneic, 1 >> dyspenic/shallow, 2 >> breathes
normally + effective cough
- Circulation = 0 >> BP > 50 mmHg of preanesthetic value, 1 >> BP
within 20-50, 2 >> BP within 20 mmHg (min SBP 90)
- Consciousness = 0 >> unconscious, 1 >> arousable to voice, 2 >> fully
awake
- Oxygen Saturation = 0 >> SpO2 <90% on O2, 1 >> SpO2 > 90% but
needs O2, 2 >> SpO2 > 92% on RA
⩥ fluid compartments.
Answer: Body water distribution = 60/40/20(15/5)
>>Water (60%) / intracellular volume (40%) / extracellular volume
(20%)
,extracellular = interstitial fluid (15%) / plasma (5%)
70 x 0.6 = 42L (60%) total body water
70 x 0.4 = 28L (40%) intracellular volume
70 x 0.2 = 14L (20%) extracellular volume
70 x 0.15 = 11L (15%) interstitial fluid
70 x 0.05 = 3.5L (5%) plasma fluid
***neonates have higher TBW by weight
***females, obese, + elderly have lower TBW by weight
⩥ plasma volume.
Answer: >> non-cellular fraction of circulating blood volume (5%)
>> pores in capillaries allow plasma to be in direct contact with the
interstitial fluid
>> net movement of fluid between the intravascular and interstitial
spaces determined by starling forces + glycocalyx
Starling forces >>
>> hydrostatic pressure PUSHES fluid
>> oncotic pressure PULLS fluid
, Glycocalyx >>
>> the endothelial glycocalyx forms a protective layer on the interior
wall of the blood vessel >> gatekeeper that determines what can pass
from the vessel into the interstitial space
>> anticoagulant properties
>> disruption of the glycocalyx contributes to capillary leak >>>
accumulation of fluid + debris in the interstitial space reduces tissue
oxygenation >>> example = sepsis, ischemia, DM, major vascular
surgery
⩥ Blood Volume.
Answer: erythrocyte = intracellular compartment
blood volume = plasma volume + blood cell volume
hct = fraction of blood that is occuied by erythrocytes
>>increased by increased number of RBCs (polycythemia) or decreased
plasma volume (hypovolemia)
>>decreased by decreased number of RBCs (anemia) or increased
plasma volume (hemodilution)
⩥ Interstitial fluid.
Answer: interstitium is the space between cells
