Chap 9

Question 1

laryngopharynx (hypopharynx)

Answer 1

the structure surrounding the entrance to the trachea

Question 2

Carina

Answer 2

trachea branches at the carina and forms two main-stem bronchi

Question 3

Lower airway

Answer 3

Below the larynx and is composed of the trachea, bronchial passages and the alveoli

Question 4

bronchoconstriction or bronchospasm

Answer 4

• the contraction of the smooth muscle that lines the bronchial passages that result in a decreased internal diameter of the airway and increased resistance to airflow
• Ex. Asthma

Question 5

2 important considerations of assessing airways

Answer 5

“Is the airway open”? and “will the airway stay open”?

Question 6

Stridor

Answer 6

high-pitched sound generated from partially obstructed airflow in the upper airway

Question 7

Airway blockage signs

Answer 7

Gurgling, gasping, crowing, wheezing, snoring, and stridor

Question 8

Sniffing position

Answer 8

upright position with their head pitched forward as if they were attempting to smell something

Question 9

2 different ways of opening airway

Answer 9

• Head-tilt, chin-lift

- Jaw-thrust

Question 10

OPA

Answer 10

Oropharyngeal

Question 11

NPA

Answer 11

Nasopharyngeal

Question 12

Gag reflex

Answer 12

vomiting or retching that results when something is placed in the back of the pharynx. This is tied to shallow reflex

Question 13

Flexible suction catheter sizes

Answer 13

French, larger the number, larger the catheter

Question 14

Suction system minimums

Answer 14

at least 30 liters a minute air intake and vacuum no less than 300mmHg when the tube is clamped

Question 15

Special considerations for suction

Answer 15

• Facial injuries
  
  • Suction for blood might need to be frequent
• Obstructions
  
  • Objects to big for suction might need manual removal
• Dental appliances
  
  • Leave in place unless it endangers airway

Question 16

Rigid pharyngeal tip (suction tip)

Answer 16

Yankauer,
tonsil sucker
Tonsil tip suction

Question 17

What happens when you put the yankauer to far down the pharynx

Answer 17

It might hit the vagus nerve in the back of the pharynx which can slow the heart rate

Question 18

Proper way to insert OPA in infant or child

Answer 18

Use a tongue depressor and slide OPA straight in versus the 180 degree method

Question 19

Different parts of a suction machine

Answer 19

Tubing
suction tip or catheters,
collection containers
Container of clean or sterile water

Question 20

Techniques of suction

Answer 20

Appropriate PPE
No longer than 10 secs(causes hypoxia)
Don’t put in farther than you can see
Suction on the way out 
Suction is best on your side

Question 21

Anatomic considerations

Answer 21

• Mouth and nose are smaller
• tongues are proportionally bigger
• trachea is softer and more flexible
• trachea is narrower and easily obstructed by swelling
• chest wall is softer which makes them depend more on diaphragm breathing
• infants require neutral neck position
• children slight extension of the neck
• use a rigid tip for children and infants
