-Format: Multiple-choice / Flashcard

Question 1: ETCO2 level indicating effective ventilation

Answer:

35-45 mm (Greater than 50 signifies depressed ventilation Question 2: In a patient who is unable to open their mouth or unresponsive, how do we assess the airway?

Answer:

Jaw- thrust maneuver is performed to open airway and mouth to assess for obstruction

Question 3: Wha is a result of inadequate oxygenation?

Answer:

Hypoxemia Resulting in anaerobic metabolism and acidosis

Question 4: If an airway is patent, what is the goal?

Answer:

Focusing efforts at maintaining and supporting a patent airway (Pt may be allowed to assume position that facilitates better air exchange so long as no CSI is suspected)

Question 5: What is a definitive airway?

Answer:

Tube securely placed in the trachea with cuff inflated.

Question 6: Can an oropharyngeal airway be used in someone with a gag reflex?

Answer:

No Question 7: Why is AVPU beneficial to use at the beginning of the initial patient assessment?

Answer:

Will help determine appropriate airway intervention

Question 8: Sign of inhalation injuries

Answer:

Singed nasal hairs Carbonaceous sputum Hoarse voice

Question 9: Why is alertness included in the airway assessment?

Answer:

Including this helps evaluate the patient's ability to protect their own airway

Question 10: What inspecting the airway, what are we inspecting for?

Answer:

Expose the patient's chest and inspect for the following:

Spontaneous breathing Symmetrical chest rise and fall Depth, pattern and rate of resps

Work of breathing (accessory muscles, pursed lip, diaphragmatic breathing) Skin colour Contusions, abrasions, deformities Open pneumothorax JVD Signs of inhalation injuries Question 12: List some conditions or situations that would require definitely secured airway

Answer:

Apnea GCS of 8 or less Severe maxillofacial fractures Evidence of inhalation injury Laryngeal or tracheal injury or neck hematoma High risk of aspiration and patient unable to protect airway Compromised or ineffective ventilation Anticipation of deterioration of neurological status

Question 13: What pneumonic is used to assess a patient level of alertness?

Answer:

A: Alert

V: Responds to verbal stimuli

P: Responds to pain

U: Unresponsive

Question 14: How to assess for proper placement of a definitive airway (3 steps)

Answer:

• Attach CO2 detector (assess for presence of CO2 after 5-6 breaths)

• Adequate rise/fall of chest with assisted ventilation

• Auscultate for gurgling over epigastrium and presence of bilateral breath sounds.
