noninvasive BP measurements are based on what?
oscillation
T/Fone reason for allowing pts to take their own Beta blocker is for cardiac protection
True
for a pt with HTN, how close do you want to keep their baseline BP within
20 percent
when deciding to use invasive vs noninvasive BP monitoring, what should you consider?
the type of case
which artery for A-line insertion has highest risk of infection?
femoral
which leads are considered standard limb leads?
which are considered augmented leads?
limb leads- I,II, III
augmented leads- AVR, AVF, AVL
ST elevation for lateral wall MI is in what leads?
I, AVL (V5, V6)
what is normal axis
-30 to 90 degrees
what EKG changes are you expecting to see with hypokalemia?
T wave flattening to T wave inversion, U wave, ST depression, increased amplitude P waves
a pt is going for an elective surgery and you see new EKG changes such as 6 ectopic beats, what should you do?
cancel the surgery b/c it is elective and consult cardiology
lower than normal SVO2 may indicate what two things?
increase in 02 demand or consumption & decrease in 02 delivery
the two main compensatory mechanisms of the body that help maintain balance between oxygen supply and demand are?
increase CO2 and increased 02
what statement about SVR is incorrect?
catecholamine release causes a decrease in SVR
what two body mechanisms assist in reduction of PVR?
recruitment and distention
the single most important factor regulating stroke volume of a normal heart beat is?
volume of blood in the ventricle prior to contraction
to maintain a steady state core temperature, the body must balance energy ____ and energy____?
gain and loss
general and regional anesthesia inhibits thermoregulation and cause significant _______ such that temperature monitoring is warranted?
vasodilation
_______ is the form of heat transfer which accounts for the majority of heat loss in the pt undergoing surgery?
radiation
which temperature monitoring sites is known as inaccurate during open chest procedures?
pulmonary artery monitoring
the most sensitive and earliest indication of malignant hyperthermia is?
increased ETC02
T/F- the “a-wave” on the cvp correlates with the “p-wave” of the ECG and represents atrial contraction?
true
what cardiac abnormality is associated with giant/cannon a-waves on cvp?
junctional rhythm
T/F you must always float the swan through the pulmonary artery with the balloon down?
false
the wedge pressure indicates what the pressure is in what side of the heart?
left
T/F practitioners should always use the most invasive means to obtain clinical data?
false
