OET READING PART B Q 1 EXPLAINED

OET READING PART B
1
Patients undergoing lung resection are jeopardized by relevant postoperative morbidity and mortality. Acute respiratory failure is the most common life-threatening complication after thoracic surgery. Supplemental oxygen is often needed to improve arterial oxygenation in the postoperative period: despite it is effective in treating most cases of hypoxemia, patients with low ventilation-perfusion ratio may be only partially responsive to an increase in oxygen concentration. Noninvasive ventilation (NIV) has been proposed to prevent/treat respiratory failure after lung resection but its routine use in clinical practice requires personnel expertise and technological resources that may not be available in all post-anesthesia care units and surgical wards. In addition, in the early postoperative period, delivery of positive pressure in the airways and eventual patient-ventilator asynchronies during assisted ventilation may pose a risk to the tightness of bronchial anastomosis by means of uncontrolled swings in the transmural pressure of the airways.

1. The paragraph explains?
A) NIV is effective in treating hypoxia
B) In the time of ventilator-patient disparities, NIV is very helpful
C) NIV needs a professional to operate.


STEP 1

READ THE QUESTION 

YOU CAN FIND THAT QUESTION IS ABOUT THE NIV


STEP 2

READ THE PARAGRAPH CAREFULLY.

NOTE THE KEYWORDS.

section 1

Patients undergoing lung resection are jeopardized by relevant postoperative morbidity and mortality. Acute respiratory failure is the most common life-threatening complication after thoracic surgery.  

NO KEYWORDS

section 2

supplemental oxygen is often needed to improve arterial oxygenation in the postoperative period: despite it is effective in treating most cases of hypoxemia, patients with low ventilation-perfusion ratio may be only partially responsive to an increase in oxygen concentration.

section 3

Noninvasive ventilation (NIV) has been proposed to prevent/treat respiratory failure after lung resection but its routine use in clinical practice requires personnel expertise and technological resources that may not be available in all post-anesthesia care units and surgical wards

IN THIS PORTION YOU CAN FIND THAT ..

NIV requires personnel expertise.. that means need a professional to operate.

to confirm the answer check further.

Option 1 

KEYWORD - hypoxia-  in section two you can find that it is effective in hypoxemia, it's not the same.


section 4

In addition, in the early postoperative period, delivery of positive pressure in the airways and eventual patient-ventilator asynchronies during assisted ventilation may pose a risk to the tightness of bronchial anastomosis by means of uncontrolled swings in the transmural pressure of the airways.

from this section, it is clear that option B is also incorrect.
