1.  What is the main application of electrical impedance tomography (EIT) in the field of medical imaging?
  1. Measurement of bone density
  2. Visualization of brain activity
  3. Monitoring changes in lung ventilation and perfusion of lung tissue in real time
  4. Assessment of cardiac function
2.  Elastic pressure in the respiratory system is required for what specific function?
  1. Expanding the chest wall and lungs
  2. Overcoming airway resistance
  3. Maintaining alveolar pressure
  4. Balancing lung elastance
3.  During an end-expiratory occlusion in a passive patient, what action is taken after applying a gentle bilateral thoracic compression?
  1. Perform an end-expiratory occlusion
  2. Wait for the next occluded inspiratory effort
  3. Perform an inspiratory occlusion
  4. Measure the increase in Paw (airway pressure) and Poes (oesophageal pressure)
4.  What does an upward trend in PetCO2 accompanied by a temporary decrease in V‘CO2, followed by a return to baseline, suggest?
  1. Improvement of ventilation
  2. Increased CO2 production
  3. Decreased CO2 production
  4. Worsening of ventilation
5.  According to the Fick principle, what must be equal for continuous measurement of cardiac output using partial CO2 rebreathing?
  1. Oxygen delivery by mixed venous blood
  2. Carbon dioxide excretion by the lungs
  3. Blood pressure in the arteries
  4. Heart rate
