"Recovery" by Dr. Leach Flashcards
T/F: Body temp is more important for general anesthesia than it is for oral sedation
true
T/F: Almost all anxiolytic drugs will depress breathing
true
Use ___________ to continually measure oxygen saturation
PULSE OXIMETRY
what are the normal Hb levels for adult females and males?
12-14 (females)
14-15 (males)
what is the most common cause of a decreased Hb level?
Anemia
T/F: Pulse Ox levels should be consistent and level
FALSE
- you will see peaks and troughs during systole and diastole
At pulse ox of 90%, the partial pressure of O2 is roughly _____ mmHg
60mm mercury
at a PO2 of _____, we are approaching hypoxia
60mmHg
When pulse ox is at ___%, that correlates to a O2 level of 27mm O2
50%
Anything that increases metabolism will shift the P50 curve to the _______
right
increased CO2, dec pH, increased temp….
which form of hemoglobin absorbs more infrared light? which form absorbs more red light?
Oxyhemoglobin : absorbs more INFRARED light (940 nm)
Deoxyhemoglobin : absorbs more RED light (660 nm)
the more ________ light that reaches the puls Ox meter, the greater the hemoglobin oxygen saturation
more RED light = more oxyhemoglobin
“_____________” is the volume of gas inhaled/exhaled in 1 minute
Minute Ventilation
a Capnogram is a diagram describing what?
CO2 concentration (in mmHg) of RESPIRATORY GASES
what happens during the 4 phases of a Capnogram waveform?
Phase I: Expiration begins, but CO2 free gas is expelled (anatomic dead space)
Phase II: Mixing of dead space gas and alveolar gas
Phase III (Expiratory Plateau): As exhalation phase continues, remaining gas expelled is almost entirely alveolar
Phase 0: inspiration beins
in a Capnogram waveform, at what point does exhalation begin?
between points A and B
what is occurring between points B and C in a capnogram?
exhaling air that was PARTIALLY involved in gas exchange
mix of alveolar and dead space air
In a Capnogram, when is the CO2 rich air of the lower lungs beginning to be exhaled?
at point C
The ____ section of a capnogram shows us the arterial CO2 pressure
C-D
*** CPR aims to maintain a CO2 concentration of what? **
10mm Hg
T/F: Systolic HTN is more common in Younger population
FALSE
DIASTOLIC HTN is more common in YOUNG people
what population group is at an elevated risk for Silent myocardial ischemia? why is this?
Diabetics
- unable to feel pain of MI due to sensory neuropathy
what is the “normal” blood glucose level?
what is Hypoglycemia?
Normal = 90
Hypoglycemia = blood glucose under 50
where do the 3 leads of an ECG read from?
a) Lead 1- right shoulder (-) to left shoulder (+)
b) Lead 2 – Right shoulder (-) to left leg (+)
c) Lead 3 – Left shoulder (-) to left leg (+)
points D to E on a capnogram represent which phase of ventilation?
inspiration
Why should Blood pressure always be taken before administering Nitroglycerin?
It can cause a large drop in BP
- if the pt is already Hypotensive, they could crash
What ECG electrode would be used to detect a Cardiac Arrhythmia? which would be used to detect Lateral Wall Ischemia?
Cardiac Arrhythmia = V1
Lateral Wall Ischemia = V5 (shows Left Ventricle)
