Q

A

22
Q

most common nasal vasoconstrictors

A

pehnylephrine
afrin

23
Q

nasal rae insertion

A

along floor of nasal passage
perpehndicular to face
bevel directed laterally

24
Q

which way is bevel during nasal rae insertion

A

bevel directed laterally

25
Q

why do we need to cover the murphy eye during nasal intubation?

A

murphy eye causes scraping, bleeding, trauma

26
Q

how do you direct the nasal Rae into glottic opening?

A

use the magil forceps

27
Q

what do you need to be cautious off when using magil forceps?

A

do not grab onto the tube cuff
it could tear

28
Q

securing nasal rae

A

pad connector
dont fishhook nare
tape circumferential

29
Q

fishhooking the nare can cause

A

cut off blood flow
blanching tissue
tissue necrosis

30
Q

head flexion with nasal rae

A

pushes NETT deeper into trachea

risk mainstem or carina stimulation

31
Q

head extension with nasal rae

A

withdraws NETT out of trachea

risk tube popping out of airway

32
Q

retrograde intubation

A

place needle through cricothyroid membrane
thread seldingwire through neck and out of mouth
place arndt catheter over seldingwire
remove selding wire
ETT over catheter
remove catheter

33
Q

retrograde intubation requires

A

time
proper MV
definitive pre-ox

34
Q

jet ventilation indications

A

removal of foreign bodies
evaluation of airway dynamics
removal of lesions

35
Q

jet ventilation limitations

A

airway pollution (open airway)
no end-tidal measuring
possible loss of airway
limits ability to multitask

36
Q

jet ventilation anesthetics

A

TIVA only

37
Q

when is jet ventilation used?

A

typically with rigid bronchoscope

38
Q

types of jet ventilation

A

supraglottic
subglottic

39
Q

supraglottic jet ventilation

A

air introduced above glottic opening
rigid bronchoscope accessory port

40
Q

subglottic jet ventilation

A

typically emergency only
small catheter intriduced through glottic or through cricothyroid membrane

41
Q

jet ventilator hooks up to what air supply?

A

wall supply
DISS
50 psi

42
Q

what should you ask surgical team about prior to starting jet ventilation?

A

ask to see the O2 jet adapter

43
Q

do you use an ETT or LMA prior to jet ventilation

A

LMA (typically Igel) w/100% FiO2

44
Q

jet ventilation handle squeeze frequency/duration

A

8 times/min
duration <1 second

45
Q

jet ventilation pressure

A

15 psi (ideal)
25-50 psi may be needed

depends on level of compliance

46
Q

how do you verify adequate pressure during jet ventilation

A

watch for chest rise

47
Q

ventilation includes

A

O2 IN
CO2 OUT

48
Q

do you paralyze during jet ventilation

A

yes

49
Q

what are common symptoms post-jet ventilation?

A

coughing
irritation

treat w/narcotics and humidified air
