RACP 2022 Q6
Pre-oxygenation is required pre-procedure to allow safe apnoea time. Safe apnoea time is reduced in obesity is due to reduction in
a. FEV1
b. FVC
c. DLCO
d. FRC

A

D

Patients living with obesity have a very different physiology in a number of ways. From a respiratory perspective, this population has a decreased Functional Residual Volume (FRC), generally lower tidal volumes, decreased compliance, higher oxygen demand, and a higher risk of atelectasis. All of these factors together result in patients with obesity desaturating significantly sooner after induction than the non-obese group.

RACP 2022A 25.
Patient with pulmonary hypertension found on echocardiogram. Chronic
thromboembolism (CTEPH) is suspected. What is the next best investigation to confirm a diagnosis?
a. D Dimer
b. CTPA
c. V/Q scan
d. Right heart cath

A

C
The recommended diagnostic work-up of suspected CTEPH starts with transthoracic Doppler echocardiography.
The next diagnostic step for patients at “intermediate” or “high” echocardiographic probability is ventilation/perfusion lung scintigraphy.

RACP 2022B Q1.
What is the primary pathology in idiopathic pulmonary arterial hypertension?
A. Angioproliferative vasculopathy of pulmonary arterioles
B. Thromboemboli of pulmonary arterioles
C. Thrombosis of pulmonary venules
D. Vasculitis of pulmonary arterioles

A

A
PAH is a proliferative vasculopathy, characterized by vasoconstriction, cell proliferation, fibrosis, and microthrombosis. Pathologic findings include hyperplasia and hypertrophy of all three layers of the vascular wall (intima, media, adventitia) in pulmonary arteries <50 microns (ie, localizes to the small pulmonary muscular arterioles). In addition, fibrosis and in situ thrombi of the small pulmonary arteries and arterioles (plexiform lesions) can be seen
