breathing system part 2 (quiz 3/11)

Question 1

The self refilling bag is the?

Answer 1

part that we squeeze

Question 2

both valves are one way valves also known as?

Answer 2

check valves

Question 3

where does oxygen and air come into the bag?

Answer 3

bag inlet valve

Question 4

when you squeeze the bag the bag inlet valve will?

Answer 4

close, this is during inspiration.

Question 5

what does the non rebreathing valve do during inhalation?

and why does it do that?

Answer 5

the non rebreathing valve is going to open during inhalation.
opening allows gas to go to the patient when you squeeze the bag.

Question 6

where is the non rebreathing valve located?

Answer 6

near the patient’s mouth area.

Question 7

Does the non rebreathing valve open or close during expiration?
what does this allow for?

Answer 7

the non rebreathing valve closes.

allowing for expired gas to go through the expiratory port.

Question 8

during expiration the bag inlet valve does what?

Answer 8

bag inlet valve opens to let oxygen and air into the self refilling bag so you can have air and oxygen for the next breath!

Question 9

can you use the Manuel resuscitator with no oxygen?

Answer 9

Yes, you can have the patient breathing just air.

Question 10

all man. resuscitators are?

Answer 10

one way valves

Question 11

peep valve located on the ?

Answer 11

expiratory… limb

Question 12

pressure limiting device does what and with what type of patients do you see it used?

Answer 12

protects against barotrauma and may prevent gases from entering the stomach during manual ventilation.
typically seen with pediatric patients.

Question 13

The higher the MV and the greater the I:E ration….. the higher or lower the delivered 02 concentration?

Answer 13

the lower the delivered 02 concentration

Question 14

ASTM requires that resuscitators deliver ?

Answer 14

fi02 of at least 40% when connected to 02 >

Question 15

TV will increase with what amount of hands?

Answer 15

two hands

Question 16

if the valve is stuck in the closed position then when you squeeze the bag it will stay?

Answer 16

deflated and no air coming into the bag part.

Question 17

if the valve is stuck in the open setting MV would stay?

Answer 17

same or go down but 02 concentration would diminish

Question 18

cold air can hold more or less moisture?

Answer 18

can hold less moisture

Question 19

as temp. decreases the air can hold?

Answer 19

less moisture, water.

Question 20

more humidity when it is?

Answer 20

warm

Question 21

warm air can hold more or less water?

Answer 21

MORE!

Question 22

RELATIVE humidity is a ratio so what is the definition of relative humidity?

Answer 22

amount of water a gas is holding in ratio to what it COULD hold.

Question 23

formula for relative humidity?

Answer 23

RH= actual vapor pressure / saturated vapor pressure x 100

Question 24

LMA decreases or increases humidification?

Answer 24

decreases humidification bc you are bypassing the nose.

Question 25

who needs humidification?

Answer 25

pediatrics, frail patients, or ones with pulmonary problems

Question 26

HME tell me what they provide or preserve?

Answer 26

they do provide any humidification or moisture they only preserve.

Question 27

exothermic ?

Answer 27

heat is produced, it exits the system

Question 28

endothermic ?

Answer 28

heat is absorbed, brought into the system

Question 29

CO2 and soda lime react and produce what kind of reaction?

Answer 29

exothermic, produces heat

Question 30

which type of HME is more efficient at moisture and temp conservation? hygroscopic or hydrophobic?

Answer 30

HYGROSCOPIC!

Question 31

Where is the HME located and where is the electric humidifier located?

Answer 31

HME is on the expiatory limb.

electric humidifier is on the inspiratory limb

Question 32

where are HME placed that make them work the best? You get the most moisture and humidification?

Answer 32

Next to the ETT bc less heat and moisture is lost if it can do its job right after the source.

Question 33

humidifiers and vaporizers work the same (humidifier may or may not be heated and a vaporizer has to be heated) so, if you have two HME and 1 vaporizer how many vaporizers do you have?

Answer 33

3 total, you count the HME in the vaporizer count.

Question 34

what are the four phases of inspiration and expiration?

Answer 34

inspiratory flow
inspiratory pause
expiratory flow
expiratory pause

Question 35

I:E ratio? stands for?

Answer 35

inspiration to expiration ratio

Question 36

WHAT is the I:E ratio normally? because the actual ratio will be based of information in the question.

Answer 36

1:2

Question 37

who needs more time to inspire?

Answer 37

restrictive lung dz, obese people

Question 38

who needs more time to exhale?

Answer 38

COPD

Question 39

sigh?

Answer 39

deliberate increase in tidal volume for one or more breaths

Question 40

Why do you sigh?

Answer 40

to recruit alveolar so you can have more gas exchange.
