Basic Airway Management

Question 1

Manual maneuvers

Answer 1

Jaw thrust, head tilt chin lift

Question 2

Oropharyngeal airway

Answer 2

Measured from corner of the mouth to tip of earlobe/angle of the jaw

Question 3

Nasopharyngeal airway

Answer 3

Measured from tip of the nose to the earlobe

Question 4

Oxygen cylinders

Answer 4

Store pure oxygen, always check label and test date, various sizes, oxygen delivery is measured in L/min

Question 5

When to replace oxygen cylinder

Answer 5

When pressure falls to 200 psi or lower (safe constant)

Question 6

How to calculate how long a tank will last

Answer 6

Tank factor X (psi on gauge) divided by L/min to be delivered

Question 7

Oxygen regulators

Answer 7

Bourbon-Gauge Flowmeter, Pressure-Compensated Flowmeter

Question 8

Oxygen humidifier

Answer 8

Bottle of sterile water that moisturizers oxygen; keep upright - only practical with fixed unit on ambulance

Question 9

Nasal cannula

Answer 9

Two small prongs; 24%-44% O2, best for patients who need long term O2 therapy

Question 10

When is a nasal cannula ineffective?

Answer 10

Apnea- poor respiratory effort, severe hypoxia, mouth breathing

Question 11

Nonrebreather Mask

Answer 11

Preferred in pre-hospital setting; 90%-100% O2, mask and reservoir bag

Question 12

Tracheostomy Masks

Answer 12

Cover the stoma and have a strap that goes around the neck; improvise by placing a face mask over the stoma

Question 13

Positive pressure ventilation

Answer 13

Patient is not breathing/breathing inadequately; need artificial ventilation with high flow supplemental oxygen.

Question 14

Bag-Valve-Mask Device

Answer 14

Can deliver nearly 100% O2, column of O2 to deliver is based on visible chest rise

Question 15

Bag-Valve-Mask Device Technique is not adequate if?

Answer 15

Chest does not rise and fall, rate of ventilation is to slow or to fast, pulse rate does not improve

Question 16

If BVM technique is not adequate, what can you do to trouble shoot?

Answer 16

Reposition the airway/head or insert an airway device, reposition the mask, check airway for obstruction

Question 17

Suctioning; yankauer catheter

Answer 17

used with adults, infants, children

Question 18

Suctioning key points

Answer 18

Removes oxygen; pre-oxygenate before suction if possible, utilize 80-120mmHg of suction pressure

Question 19

Maximum suctioning time

Answer 19

Adult: 15 seconds
Child: 10 seconds
Infant: 5 seconds

Question 20

How to measure yankauer catheter?

Answer 20

Corner of the mouth to the earlobe
