Question 1

Operating principle of manual resuscitation bag

Answer 1

Portable hand held device
Delivers positive pressure to airway
Ventilate pt

Question 2

Common uses of manual resuscitators

Answer 2

Ventilate during CPR and transport
Hyperventilate pre/post suction
Management of mechanically ventilated pts

Question 3

Standard fittings on manual resuscitator and which attaches to mask or ET tube

Answer 3

15mm inner diameter -> connects to ET/trach

22mm outer diameter -> connects to mask

Question 4

Types of patient valves and which allow spontaneous inhalation

Answer 4

Spring loaded

Diaphragm: leaf/duckbill/fish (spontaneous)

Question 5

Good self-inflating mask characteristics

Answer 5

Easy to disinfect/sterilize
Standard sizes
High FiO2 @ high SV/rate
Self inflating
Non-rebreathing (one way valve)
Adults, peds, and infant sizes

Question 6

Troubleshooting of manual resuscitator: bag fills quickly but depletes easily

Answer 6

inlet valve

Question 7

Purpose of pressure relief valve

Answer 7

Prevent excessive pressure in peds/infants

Decrease barotrauma/pneumo

Question 8

What pressure does a pressure relief valve function off of

Answer 8

40 cmH2O

Question 9

What effects oxygen concentration delivery of self-inflating resuscitator

Answer 9

Rate
O2 flow
Refill time
Stroke volume
Reservoir capacity

Question 10

Effect of rate on O2 concentration

Answer 10

Faster rate -> decreased FiO2

Slower rate -> increased FiO2

Question 11

O2 flow effect on O2 concentration

Answer 11

Higher flow -> increased FiO2

Lower flow -> decreased FiO2

Question 12

Reservoir capacity effect on O2 concentration

Answer 12

no reservoir -> 35-40% @ 10-15lpm
Reservoir present -> up to 100% @ 10-15 lpm
Increased size -> increased FiO2

Question 13

Refill time effect of O2 concentration

Answer 13

Increased time -> increased FiO2

Decreased time -> decreased FiO2

Question 14

SV effect on O2 concentration

Answer 14

Increased SV -> decreased FiO2

Decreased SV -> increased FiO2

Question 15

Observations tho assure ventilation

Answer 15

Rise and fall of chest
Breath sounds
ABG
Oximetry

Question 16

Hazards of bag-mask resuscitation and how to prevent

Answer 16

Gastric insufflation -> intubate ASAP
Vomit/aspiration -> decreased compliance -> intubate ASAP
Barotrauma -> don’t squeeze until pop-off
Pneumothorax -> one-sided chest rise
Hypoventilation -> use both hands, check bs

Question 17

Pneumatic resuscitator/demand valve

Answer 17

50 psi source
Press lever
Adults only
Can be triggered by neg pressure

Question 18

Advantages and disadvantages of pneumatic

Answer 18

Adv -> 100% FiO2, can go solo

Dis -> 50 psi source, cannot feel compliance

Question 19

Potential hazards of pneumatic

Answer 19

Barotrauma -> gastric distension -> pneumothorax

Question 20

PEEP valve indications

Answer 20

Pt on PEEP w vent -> match PEEPS
Increase oxygenation when FiO2 insufficient (refractory hypoxemia)
Increase FRC

Question 21

Effect of PEEP on ABG and how/why

Answer 21

Increase PaO2 -> increasing oxygenation -> pop open alveoli and keep open

Question 22

Equipment needed for transportation

Answer 22

Mask, stuff for emergency trach

Tank

Question 23

Affect of aspiration on lung compliance when ventilating a pt with a manual resuscitator

Answer 23

Decreased, squeeze bag harder

Question 24

As patients lung compliance increases, RT should

Answer 24

Ease up on compression depth

Question 25

troubleshooting manual resuscitator: hard to squeeze

Answer 25

mucous plugging

Question 26

troubleshooting manual rescusitator: high flow

Answer 26

valve jam -> decrease FiO2 flow
