Week 2: Patient Prep and Contrast Agents Flashcards
Why are laboratory values important
if patient is candidate for iodinated contrast
What laboratory values show info about patients kidney functions?
serum creatinine, BUN, eGFR
Normal range of Serum Creatinine
Canada: 50-90 umol/L for female
70-120 for male
American- 0.6-1.7 mg/dl
Normal Range of BUN
7-25 mg/dL
Normal Range of eGFR
above 60ml/min/1.73m
What goes eGRF measure
how much blood passes through kidneys per minute
What provied information about bloods coagulation ability
Prothrombin PT
Partial Thromboplastin time PTT
Platelet Count
Typical Range of PT
11-14 seconds
Typical Range of PTT
25-35 seconds
Typical Platete Count
150,00- 400,000 platekets per mm3
What blood thinners should we pay attention to
Warfarin, Coumadin, Heparin, Plavix, aspirin
Normal range of oral temperature
36.0 - 38.0 C
Average adult pulse
60-100 bpm
Average childs pulse
95-110 bpm
Average infants pulse
100-160 bpm
Adult normal respiration rate
14-20
adolescent youth normal respiration rate
18-22
a child’s normal respiration rate
22-28
Infancts normal respiration rate
30 or greater
Healthy adults BP range
120/80 mmHG
Why are iodinated Contrast agents good
-safe
-water solvable
-easy to administer
-easily distributed/ eliminated by body
Why do IV agents show large attenuation difference between structures
-different tissues enhance differently
-shows different in normal vs abnormal tissue
What is Osmolality
-number of particles in solution per unit liquid as compared with blood
-major factor in non-allergic reactions
High-osmolality compared to blood (HOCM)
7 time blood osmolaity
Isomolar agents compared to blood (IOCM)
same compared to blood (290 most/Kg H20
