Respiratory Medicine Flashcard Deck - 10 Cards
Flashcard 161: What are the different types of respiratory pressure support (least → most invasive)?
_____
CPAP
NIV (BiPAP)
Mechanical ventilation
Answer: High-flow nasal cannula (HFNC)
Flashcard 162: What pathophysiological mechanisms cause type 1 respiratory failure?
_____, abnormal diffusion, right to left cardiac shunts, low inspired oxygen tension (low FiO2)
Answer: Ventilation/Perfusion (V/Q) mismatch
Extra: Type 1 Respiratory Failure (Hypoxemic) is defined by PaO2 < 60 mmHg with normal/low PaCO2.
Note: Hypoventilation primarily causes Type 2 (Hypercapnic) Respiratory Failure (PaCO2 > 45 mmHg).
Flashcard 163: What pathophysiological mechanism causes type 2 respiratory failure?
_____ with or without V/Q mismatch
Answer: hypoventilation
Flashcard 164: Definitions:
Type 1 respiratory failure: _____
Type 2 respiratory failure: Hypoxia (<8kPa) AND hypercapnia (>6.0kPa)
Answer: Hypoxia (<8kPa) AND normo/hypocapnia
Flashcard 165: What is the main side effect of bleomycin (chemo)?
_____
Answer: Pulmonary fibrosis
Flashcard 166: Patients with superior vena cava syndrome can present with _____ due to venous congestion of the airway
Answer: dyspnoea

Answer: malignancy (mostly lung cancer)
Flashcard 168: A patient with known lung cancer presents with facial swelling and a distended jugular vein. What is the most likely diagnosis?
_____
Answer: Superior vena cava obstruction
Flashcard 169: Vaccination against pneumococcal 23 serotypes is given _____
Answer: at 65 years old
Extra: Current CDC guidelines for pneumococcal vaccination in adults ≥65 years:
- If never received a pneumococcal conjugate vaccine: Administer PCV15 followed by PPSV23 (after 1 year) OR administer PCV20 alone.
- PPSV23 contains 23 purified capsular polysaccharide antigens.
