• High elastance

• High metabolic demand

• All of above

A 65 years lady with history of IHD. Having breathlessness, received in ICU. she is desaturating in spite of 100% oxygen through NRBM. Which one is best option?

• High flow nasal cannula

• Non-invasive ventilation

• Intubation and mechanical ventilation

• Asthaline nebulization

Recommended settings in ARDS are

• Low rate, low tidal volume, high peep

• High rate, low tidal volume, low peep

• High rate, high tidal volume, high peep

• High rate, low tidal volume, high peep

Patient is on ventilator with volume control mode, sedated and paralyzed. peak pressure 25 cm H2O. And pause pressure = 20cmH2o. Suddenly peak pressure shoots up 45cm H2O and pause pressure= 40cm H2O , What immediate action will you take?

• Ask for chest x-ray to rule out pneumothorax

• Decrease tidal volume to maintain plateau pressure around 30cm H2O

• Decrease the respiratory rate and increase i.e ratio

• Switch the PRVC mode

Following mode works on close loop ventilation principle except

• Adaptive support ventilation (ASV)

• Synchronised intermittent mandatory ventilation. (SIMV)

• Pressure regulate volume control (PRVC)

• Adaptive pressure control (APV)

Which of following mode is recommended in central sleep apnea?

• Pressure support

• CPAP

• Spontaneous (S)

• Spontaneous timed (S/T)
