Total questions: 10
Worksheet time: 6mins
What are the mechanisms leading to Ventilator-Induced Lung Injury (VILI)?
Overdistension of alveoli
Repeated recruitment and collapse of alveoli
Inflammatory mediators
High FiO2
Choose the correct strategy regarding the aims of mechanical ventilation in ARDS
Limit tidal volume
Limit FiO2
Limit minute ventilation
Limit PEEP
When should you consider to reduce PEEP in Lung Protective Strategy?
Increasing vasopressor requirements
Improvement in oxygen saturation
Pplat of 28 cm H2O
Unable to achieve set tidal volume
You are setting the ventilator for a patient with severe ARDS. The patient is dependent on an FiO2 of 1.0. The PEEP that should be set for the patient is
5 cmH20
8 cmH2O
10 cmH2O
18 cmH2O
You are ventilating a patient with severe ARDS. The patient's Ideal Body Weight is 60kg. Which of the following will be your initial settings?
TV 360ml
RR 18
FiO2 0.5
PEEP 5 cmH2O
You are ventilating a patient with ARDS. You notice that the Pplat is 35 cm H2O. You should
decrease RR
decrease PEEP
decrease pressure support
decrease TV
Which of the following are strategies when ventilating the obstructive lung with hypercapnoea?
Increase RR
Prolong expiration time
Ensure Ppeak is not more than 30
Increase tidal volume
While ventilating your severe asthma patient, you notice that the pressure alarm has set off. The generated tidal volume is 150ml. Patient starts to desaturate. What should you do?
Increase tidal volume
Increase set pressure limit
Increase RR
Convert to pressure setting
How do you rectify the highlighted issue in this asthma patient?
add on magnesium sulphate
disconnect the ventilator
increase inspiratory flow rate
continuous nebulised salbutamol
A rising Pplat in the severe asthma could indicate
Worsening bronchospasm
Expansion of pneumothorax
Inadequate bronchodilator use
Inadequate minute ventilation
