Capnographyyy!

Question 1

What is capnography?

Answer 1

continuous analysis and recording of carbon dioxide concentrations in respiratory gases

Question 2

What value does a capnography obtain on a cardiac monitor?

Answer 2

ETCO2

Question 3

What is normal ETCO2 value?

Answer 3

35-45mmHg

Question 4

What is ETCO2 value is hypoventilation?

Answer 4

> 45mmHg

Question 5

What is ETCO2 value is hyperventilation?

Answer 5

<35mmHg

Question 6

___ RR + ____ CO2 = hyperventilation

Answer 6

high rr, low co2

Question 7

___ RR + ____ CO2 = hypoventilation

Answer 7

low rr, high co2

Question 8

Capnography benefits:

Answer 8

reflects ventilation
hypoventilation/apnea detected right away

Question 9

How many phases are in a normal waveform?

Answer 9

4

Question 10

Phase III is the…..

Answer 10

expiratory phase!!

Question 11

What phase is the ETCO2 is matched and measured CO2?

Answer 11

end of phase III

Question 12

CAPNOGRAPHY: Esophageal Intubation?

(Wave form + management)

Answer 12

absence of wave form!
Management would be: RE INTUBATE

Question 13

CAPNOGRAPHY: CPR?

(Wave form + value + management)

Answer 13

Squarebox waveform
10-15mmHg
Management- change rescuers if ETCO2 falls below 10mmHg

Question 14

If ETCO2 stays under 10mmHg for a prolonged period of time… what does this mean?

Answer 14

the chance of a ROSC LOWERS

Question 15

CAPNOGRAPHY: Obstructive airway?

(Wave form + management)

Answer 15

shark fin!!!!! -prolonged expiratory phase
can be seen before actual attack
indicative of bronchospasm (asthma, COPD, allergic reaction)

Question 16

CAPNOGRAPHY: ROSC?

(Wave form + management)

Answer 16

Sudden jump in ETCO2 value

management- check for pulse

Question 17

CAPNOGRAPHY: HYPOVENTILATION?

(Wave form + management)

Answer 17

prolonged waveform
>45mmHg
management- assist ventilations or intubate as needed

Question 18

CAPNOGRAPHY: HYPERVENTILATION?

(Wave form + management)

Answer 18

shortened waveform
ETCO2 <35mmHg
management- if conscious; coaching, if unconscious, slow ventilations

Question 19

How can you use to do identify ROSC in cardiac arrest?

Answer 19

ETCO2
Perfusion (pinking up)
Decreased compliance during oxygenation - personal breathing on their own
