ANS 5160 Intro to Clinical Anesthesia (Lecture
4)
Where do we place the pulse ox? Same side as IV
Where do we place BP cuff? Opposite arm of IV
What type of patient should we Pts with
be careful for when choosing - AV fistula/graft
which arm to place the BP cuff?
- Lymph node dissections
Why should we not put a BP cuff End stage renal disease / dialysis
on the same side as an AV
fistula/graft
Why should we not put a BP cuff Risk of lymphodema
on the same side as a lymph
node dissection?
How many ECG electrodes are there 3-5 (sometimes 12)
in the OR?
black, red, white
What colors are used in a 3 lead
ECG?
How often do you take BP? every 3-5 min
ASA Standard Monitors ECG, pulse ox, BP, temp, gas analyzer
Which ASA monitor is NOT ECG
stored on the computer during
the case? (important to print
out at beginning of case)
Sinus node, AV node, Bundle of His, L/R
bundle branches, Purkinje fibers
Electrical rhythm of heart pathway
, What receives the action potential Myocyte
and squeezes heart?
What "powers" the electrical rhythm electrolytes (Na, K, Ca, Cl)
of the heart?
1 action potential is equal to 1 depol + 1 repol
Atrial depolarization (contraction)
P wave represents
Left side of the p-wave represents RA depolarization
Right side of the p-wave represents LA depolarization
atrial depolarization
What does the PR interval
represent?
ventricular depolarization
QRS complex represents
Where is atrial repolarization on an masked by QRS complex
ecg?
Why is the QRS complex larger than Ventricles are much bigger
the P wave?
ventricular repolarization
T wave represents
No electrical impulse registered
What happens during the ST
segment?
ischemia
ST segment depression and
elevation is a sign of...
PR and ST
Which two segments should always
be on the same level
junction of s wave and start of st segment
J point
The J point can reveal different heart pathologies
Ideally, the J point should be where? Midline
Electrolyte abnormalities present Any interval
themselves in what part of an EKG?
