CH 6 pt. 1- Airway management & O2 therapy

Question 1

Impact of head tilt chin lift on C-spine

Answer 1

opens the air way but comprimises c-spine

Question 2

Name the types of airway adjuncts (5)

Answer 2

oropharyngeal airway (OA)
nasalpharyngeal airway (NPA)
manual suction
head tilt/chin lift
jaw thrust

Question 3

Name the types of oxygen delivery devices (6)

Answer 3

resuscitation mask
bag valve mask (BVM)
pulse Ox
Oxygen
nasal cannula
non-rebreather mask (NRM)

Question 4

3 advantages of breathing devices

Answer 4

1. increases O2 in the blood stream
2. enhanced performance of artificial respiratory
3. decreased risk of transmission

Question 5

what is an oropharngeal airway adjunct & when should you take it out?

Answer 5

device that is inserted in the mouth of an unresponsive person.
Take it out if the person gags

Question 6

what is an nasopharyngeal airway adjunct & when should you not use one?

Answer 6

Device used to assist in maintaing an airway in a responsive or unresponsive adult
-Not used if the person has head trauma, facial or skull fracture, raccoon eyes/broken nose

Question 7

what sign tells you to use a manual suction/has debris in their mouth?

Answer 7

they will gurgle

Question 8

flow rate of resuscitation mask & when to use

Answer 8

flow rate 6-10LPM & use when someone is under respiratory arrest or distress/cannot breath for themselves

Question 9

BVM flow rate, primary & secondary use & how many responders needed?

Answer 9

15+ LPM
primary- ventilate a non-breathing patient
secondary- assisted ventilation on a breathing patient in respiratory distress

Must be used with 2 responders

Question 10

advantages & disadvantages of BVM

Answer 10

adv.- more 02 than mouth to mouth mask (90%+)
-decrease risk of transmission

dis- takes regular practice to be proficient
-longer assembly time

Question 11

define pulse oximetry

Answer 11

measurement of percent of oxygen saturation of the blood and pulse

Question 12

define pulse oximeter

Answer 12

the device that measures percent of hemoglobin saturated with oxygen

Question 13

name 6 csigns/symptoms of hypoxia

Answer 13

1. increased respiration rate
2. increased heart rate
3. restlessness
4. cyanosis
5. chest pain
6. changes in responsiveness

Question 14

name the required items (4) for the oxygen tank (supplemental O2)

Answer 14

1. O2 cylinder
2. pressure regulator with flow meter
3. key
4. delivery device

Question 15

nasal cannula: flow rate, hypoxia rate needed, may be ineffective when (3)…

Answer 15

1-4LPM
02 (91-94%)
Ineffective when:
- nasal injury
-nasal illness
-do not use if facial fracture is present

Question 16

Non-rebreather mask: flow rate,Hypoxia state & when to use

Answer 16

10+LPM
02 (86-90%)
Use when the person is breathing

Question 17

when to use supplemental oxygen (6)

Answer 17

1. asphyxiation (suffocation)
2. dyspeana
3. hypoxia
   4.SpO2 lower than 95%
4. carbon monoxide poisoning
5. decompression sickness

Question 18

when working with O2 cylinders always… (5)

Answer 18

1. use pressure gauges & regulators designed for oxygen use
2. mainatin hardware in good condition
3. use medical grade O2
4. store O2 in cool, ventilated room
5. have cylinders checked every 5 years

Question 19

when working with O2 cylinders never… (7)

Answer 19

1. drop a cylinder/let it fall
2. leave a cylinder free standing
3. allow smoking around O2
4. operate open flames or sparks
5. use adhesive tape on tank
6. drag or roll O2 tank
7. Leave O2 flowing when using AED
