T/F: Almost all anxiolytic drugs will depress breathing

Answer 2

true

Question 3

Use ___________ to continually measure oxygen saturation

Answer 3

PULSE OXIMETRY

Question 4

what are the normal Hb levels for adult females and males?

Answer 4

12-14 (females)

14-15 (males)

Question 5

what is the most common cause of a decreased Hb level?

Answer 5

Anemia

Question 6

T/F: Pulse Ox levels should be consistent and level

Answer 6

FALSE

• you will see peaks and troughs during systole and diastole

Question 7

At pulse ox of 90%, the partial pressure of O2 is roughly _____ mmHg

Answer 7

60mm mercury

Question 8

at a PO2 of _____, we are approaching hypoxia

Answer 8

60mmHg

Question 9

When pulse ox is at ___%, that correlates to a O2 level of 27mm O2

Answer 9

50%

Question 10

Anything that increases metabolism will shift the P50 curve to the _______

Answer 10

right

increased CO2, dec pH, increased temp….

Question 11

which form of hemoglobin absorbs more infrared light? which form absorbs more red light?

Answer 11

Oxyhemoglobin : absorbs more INFRARED light (940 nm)

Deoxyhemoglobin : absorbs more RED light (660 nm)

Question 12

the more ________ light that reaches the puls Ox meter, the greater the hemoglobin oxygen saturation

Answer 12

more RED light = more oxyhemoglobin

Question 13

“_____________” is the volume of gas inhaled/exhaled in 1 minute

Answer 13

Minute Ventilation

Question 14

a Capnogram is a diagram describing what?

Answer 14

CO2 concentration (in mmHg) of RESPIRATORY GASES

Question 15

what happens during the 4 phases of a Capnogram waveform?

Answer 15

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

Question 16

in a Capnogram waveform, at what point does exhalation begin?

Answer 16

between points A and B

Question 17

what is occurring between points B and C in a capnogram?

Answer 17

exhaling air that was PARTIALLY involved in gas exchange

mix of alveolar and dead space air

Question 18

In a Capnogram, when is the CO2 rich air of the lower lungs beginning to be exhaled?

Answer 18

at point C

Question 19

The ____ section of a capnogram shows us the arterial CO2 pressure

Answer 19

C-D

Question 20

*** CPR aims to maintain a CO2 concentration of what? **

Answer 20

10mm Hg

Question 21

T/F: Systolic HTN is more common in Younger population

Answer 21

FALSE

DIASTOLIC HTN is more common in YOUNG people

Question 22

what population group is at an elevated risk for Silent myocardial ischemia? why is this?

Answer 22

Diabetics

• unable to feel pain of MI due to sensory neuropathy

Question 23

what is the “normal” blood glucose level?

what is Hypoglycemia?

Answer 23

Normal = 90

Hypoglycemia = blood glucose under 50

Question 24

where do the 3 leads of an ECG read from?

Answer 24

a) Lead 1- right shoulder (-) to left shoulder (+)
b) Lead 2 – Right shoulder (-) to left leg (+)
c) Lead 3 – Left shoulder (-) to left leg (+)

Question 25

points D to E on a capnogram represent which phase of ventilation?

Answer 25

inspiration

Question 26

Why should Blood pressure always be taken before administering Nitroglycerin?

Answer 26

It can cause a large drop in BP

- if the pt is already Hypotensive, they could crash

Question 27

What ECG electrode would be used to detect a Cardiac Arrhythmia? which would be used to detect Lateral Wall Ischemia?

Answer 27

Cardiac Arrhythmia = V1

Lateral Wall Ischemia = V5 (shows Left Ventricle)
