Airway Management Flashcards

A 6-year-old child requires intubation. Using the formula (age/4) + 4, what is the correct uncuffed ETT size for a 4-year-old?

Answer: 5.0 mm

Using (4/4) + 4 = 5.0 mm, which is the appropriate uncuffed tube size for a 4-year-old child.

What is the correct depth of ETT insertion for an average adult male measured at the teeth?

Answer: 19-23 cm

In adult males, the ETT is typically secured at 21-23 cm at the teeth to ensure proper positioning above the carina.

Which of the following describes the BURP maneuver and its purpose during intubation?

Answer: Backward, Upward, Rightward Pressure on the thyroid cartilage to improve glottic view

BURP (Backward, Upward, Rightward Pressure on the thyroid cartilage) is an external laryngeal manipulation that improves the laryngoscopic view of the glottis.

In a patient with severe facial trauma making oral intubation impossible and BVM ineffective, what is the definitive surgical airway procedure?

Answer: Surgical cricothyrotomy

Surgical cricothyrotomy provides a definitive surgical airway with adequate tidal volumes when other methods have failed.

A patient has a history of malignant hyperthermia. Which RSI drug should be AVOIDED?

Answer: Succinylcholine

Succinylcholine is a known trigger for malignant hyperthermia and should be avoided in patients with this history or susceptibility.

When using a bag-valve-mask, what tidal volume should be delivered to an apneic adult patient?

Answer: 500-600 mL

Current guidelines recommend 500-600 mL tidal volumes with BVM to achieve visible chest rise while minimizing gastric inflation.

Which anatomical landmark is used to identify the cricothyroid membrane for cricothyrotomy?

Answer: Space between the thyroid cartilage and cricoid cartilage

The cricothyroid membrane lies between the thyroid cartilage superiorly and the cricoid cartilage inferiorly and is palpated in the midline.
