Respiratory and Airway Management — Flashcards

Flashcard 51: Phase _____ of normal capnography is sharp rise in pCO2 to a plateau indicating sampling of transitional gas between the airways and alveoli

Answer: II

Flashcard 52: In the Berlin definition of Acute Respiratory Distress Syndrome (ARDS), what is the PaO2/FiO2 ratio threshold for diagnosis?

Answer: ≤ 300 mmHg (with PEEP or CPAP ≥ 5 cmH2O)

Extra: ARDS Severity Categories (Berlin Definition): • Mild: 200 < P/F ratio ≤ 300 • Moderate: 100 < P/F ratio ≤ 200 • Severe: P/F ratio ≤ 100

Flashcard 53: Percentage of glottic opening (POGO score) and Cormack Lehane (CL) classification is broadly used to describe _____ view during direct laryngoscopy

Answer: laryngeal

Flashcard 54: Management of flail chest with respiratory failure is _____

Answer: IPPV

Flashcard 55: Is extreme obesity an indication or contraindication for IPPV (controlled ventilation) during anesthesia?

Answer: Indication

Flashcard 56: Which ventilatory mode can lead to potential hyperventilation?_____

Answer: Assist control mode ventilation

Flashcard 57: Laryngeal mask airway is associated with _____ risk of gastrointestinal aspiration when compared with tracheal intubation.

Answer: increased

Flashcard 58: Patients with an RSBI _____ are eligible candidates for successful extubation

Answer: < 105

Extra: RSBI (Rapid Shallow Breathing Index) = Frequency / Tidal Volume (f/Vt in Liters). An RSBI < 105 breaths/min/L is a predictive parameter for successful weaning and extubation.

Flashcard 59: _____ Ventilation is time-triggered, time-cycled, and pressure-limited.

Answer: Pressure Controlled
