Airway Quiz

Question 1

What do Snoring Respirations mean?

Answer 1

Studies suggest snoring respirations are vibrations caused by relaxing upper airways that partially close while you’re asleep. Snoring respirations are entwined with sleeping position, sleep stage, and whether we breathe through the nose or mouth.

Question 2

What is capnography?

Answer 2

Capnography is the monitoring of the concentration or partial pressure of carbon dioxide in the respiratory gases. Its main development has been as a monitoring tool for use during anesthesia and intensive care.

Question 3

What is cyanosis and what causes it?

Answer 3

Cyanosis, broadly speaking, is caused by disorders of deoxygenated hemoglobin and disorders of abnormal hemoglobin. Oxygen might not reach hemoglobin in an adequate or sufficient amount as a result of conditions affecting the respiratory system, cardiovascular system, and the central nervous system

Question 4

When is a BVM used?

Answer 4

A BVM should be used when you need to deliver high concentrations of O2.

Question 5

What are Crackles, Stridor, Rales, Rhonchi?

Answer 5

• Crackles – Fluid in the lungs
• Rhonchi – Disease (pneumonia)
• Stridor – Infection in upper airway
• Rales – Rales are abnormal lung sounds that are rattling sounds or like a Velcro fastener being opened.

Question 6

What is shallow breathing?

Answer 6

Shallow breathing, or chest breathing is the drawing of minimal breath into the lungs, usually by drawing air into the chest area using the intercostal muscles rather than throughout the lungs via the diaphragm. Shallow breathing can result in or be symptomatic of rapid breathing and hypoventilation.

Question 7

What is a patent airway?

Answer 7

Patent airway. An airway that is open and clear and will remain open and clear without interference to the passage of air into and out of the body. Stridor. A high pitched sound generated from partially obstructed air flow in the upper airway.

Question 8

Best way to assess lungs?

Answer 8

Auscultation using a stethoscope.

Question 9

What is inhalation?

Answer 9

Inhalation is the process or act of breathing in, taking air and sometimes other substances into your lungs.\

Question 10

What is exhalation?

Answer 10

The act of breathing out air. During exhalation, the diaphragm relaxes and moves upward, causing compression of the lungs and an outward flow of air. Also called expiration.

Question 11

What is ventilation?

Answer 11

Ventilation: The exchange of air between the lungs and the atmosphere so that oxygen can be exchanged for carbon dioxide in the alveoli (the tiny air sacs in the lungs).

Question 12

How long without O2 for brain damage?

Answer 12

4-6 min possible

6-10 min very likely

Question 13

What is an OPA?

Answer 13

An oropharyngeal airway (also known as an oral airway, OPA or Guedel pattern airway) is a medical device called an airway adjunct used to maintain or open a patient’s airway.

Question 14

What is gastric distention?

Answer 14

When using a BVM or any other ventilation device, be alerted for gastric distention, inflation of the stomach with air.

Question 15

What is cystic Fibrosis?

Answer 15

CF is a genetic disorder that affects the lungs and digestive system

Question 16

What sounds are in asthma and when does it happen?

Answer 16

Wheezing during inspirations/expiration. Excessive mucus in the bronchioles.

Question 17

What is croup?

Answer 17

Infection of the upper airway. Seal barking sounds

Question 18

Symptoms of hyperventilating?

Answer 18

Shortness of breath, or feeling that you can’t get enough air
A faster than normal heartbeat
Feeling faint, dizzy, or lightheaded
Pain or tightness in your chest
Frequent yawn or sighs
A numb, tingly feeling in your hands or feet

Question 19

What is acute pulmonary edema?

Answer 19

Pulmonary edema occurs when fluid accumulates in the air sacs of the lungs – the alveoli – making it difficult to breathe. This interferes with gas exchange and can cause respiratory failure. Pulmonary edema can be acute (sudden onset) or chronic (occurring more slowly over time).

Question 20

Adequate Breathing?

Answer 20

12-20 breaths/min
Regular inhalation/exhalation
Adequate depth(tidal volume)
Unlabored without adventitious breath sounds.

Question 21

Drawback of manual ventilation?

Answer 21

Should not be used on patients with COPD or suspected cervical spine or chest injuries. Has difficulty maintaining airway.

Question 22

When to replace O2 tank?

Answer 22

500 psi

Question 23

Prone airway management?

Answer 23

The prone position improves oxygenation in intubated patients with acute respiratory distress syndrome.

Question 24

Supine airway management?

Answer 24

supine is the most dangerous position for a patient with a compromised airway. The most detrimental position for a patient, from an airway perspective, is flat on their back. Supine is best described as the “COFFIN position,” or “Cannot Oxygenate Face Flat In Neutral position.

Question 25

How much PSI in full O2 canister?

Answer 25

2000 PSI

Question 26

Hypoxia?

Answer 26

When cells and tissues do not get O2 they die. Lates signs include cyanosis. Early signs of hypoxia are anxiety, confusion, and restlessness; if hypoxia is not corrected, hypotension will develop. As hypoxia worsens, the patient’s vital signs, activity tolerance, and level of consciousness will decrease.

Question 27

What organ can survive the longest without O2?

Answer 27

Vascular Smooth Muscles

Question 28

What organ can survive the least without O2?

Answer 28

Brain
