Pre-Quiz

The main indication for mechanical ventilation is

• Postoperative recovery

• Altered conscious level

• Pulmonary edema

• Inability to protect the airway

Criteria for starting mechanical ventilation is often a clinical one. Which of the following is NOT an Indicator:

• Significant chest trauma

• Tidal volume <10ml/kg or Vital capacity <20ml/kg

• Respiratory rate >35 or <5 breaths/ minute

• Exhaustion, with laboured pattern of breathing

Positive Pressure Ventilation can only be delivered via Invasive (Tracheal Intubation) Method

• True

• False

Volume cycled and Pressure preset are two types of Ventilatory Breaths

• True

• False

Controlled Mechanical Ventilation is not often used in ICU due to:

• Unstable Hemodynamics

• Difficulty in weaning

• Patient Dyssynchrony

• None of above

Assisted Mechanical Ventilation reduces the need of:

• FiO2

• Minute Ventilation

• Heavy sedation

• Inspiratory Pressures

Patient can breathe spontaneously and unassisted in Intermittent mandatory ventilation

• True

• False

PEEP causes a rise in intrathoracic pressure and precipitate:

• Hypoxemia

• Hypotension

• Hypothermia

• Hypokalemia

Continuous Positive Airway Pressure (CPAP) is effective only in spontaneously breathing patients.

• True

• False

Very high inflation pressures may cause barotrauma to the lungs. At what pressures do we need to limit airway pressures:

• 35cmH2O

• 40cmH2O

• 45cmH2O

• 50cmH2O
