1
Q

Intubation Indications

A

Unable to swallow
cannot ventilate/oxygenate (failed airway algorithm)
GCS <8
Expected clinical course (inhal. burns, circum. burns, anaphylaxis)
Apnea
Airway obstruction
Respiratory Failure

2
Q

In respiratory failure, only one value needs to be off to indicate the need to intubate. These values include:

A

pH, CO2, PaO2

3
Q

LEMON pneumonic

A
Look
Evaluate 3-3-2
Mallampati (I-IV)
Obstructions
Neck Mobility
4
Q

3-3-2 rule

A

3 fingers in mouth
3 fingers btw jaw and hyoid
2 fingers between hyoid and thyroid

5
Q

Airway Grading

A

Mallampati

6
Q

Mallampati I

A

Patients with a tall, thin neck are usually graded Mallampati

A

I

8
Q

Difficulty level of Mallampati I

A

none

9

A

Tonsillar pillars hidden by tongue

10
Q

Difficulty level of Mallampati II

A

none

11
Q

Mallampati III

A

Only base of uvula seen

12
Q

Difficulty level of Mallampati III

A

Moderate

13

A

Miller

17
Q

Direct downward pressure on the thyroid cartilage occluding esophagus and preventing aspiration during intubation:

A

Sellick’s Maneuver

18
Q

Do NOT release Sellick’s Maneuver or BURP until intubation is

A

complete

19
Q

BURP pneumonic

A

Backward
Upward
Rightward
Pressure

20
Q

FAILED AIRWAY ALGORITHM

A

Patient requires secured airway
3 attempts of direct laryngoscopy unsucc.
Ventilate by BVM/simple airway/blind airway
Unable to ventilate/oxygenate SaO2 >90%
Cricothyroidotomy indicated (Cric)

21
Q

Gold standard of placement confirmation

A

Chest X-ray

22
Q

Distal tip of ETT should be

A

2-3 cm above carina or
1” above carina or
level of T2 or T3 vertebrae

23
Q

2nd most reliable confirmation method

A

visualization of tube passing thru cords

24
Q

When inflating the distal cuff on an ETT, the pressure should be between

A

20-30 mmHg to prevent mucosal tissue damage (only use amt required to make good seal)

25
Q

Consider saline instead of air in ETT

A

cuff

26
Q

Tube check

A

Bulb placed over ETT after intubation to confirm placement

27
Q

End tidal CO2

A

Measurement of CO2 in expired air; confirms ETT placement in trachea

28
Q

Colimetric Device

A

one-time device that changes colors when CO2 passes through it

29
Q

CapnoCheck

A

reusable ETCO2 device that both ETCO2 and RR (aka EMMA Emergency Capnometer)
