Ventilator Quiz

What is the primary function of ventilators?

• To monitor heart rate

• To provide nutritional support

• To artificially ventilate the lungs

• To administer medication

Which type of ventilator is primarily used in hospitals for intensive care?

• Portable ventilators

• Negative-pressure ventilators

• Home care ventilators

• Intensive care respirators

What is a key characteristic of positive-pressure ventilators?

• They are only used for short-term treatment

• They create negative pressure in the pleural cavity

• They are less sophisticated than negative-pressure ventilators

• They apply pressure greater than atmospheric pressure

What is the main drawback of negative-pressure ventilators?

• They are only suitable for chronic conditions

• They are too expensive to manufacture

• They can create a venous blood pool in the abdomen

• They are too small for patient use

In mandatory ventilation, what does the ventilator control?

• Only the tidal volume

• All parameters of the breath

• Only the respiratory rate

• Only the oxygen concentration

What does CPAP stand for in the context of spontaneous ventilation?

• Cyclic Positive Airway Pressure

• Continuous Positive Airway Pressure

• Constant Positive Airway Pressure

• Controlled Positive Airway Pressure

What is the purpose of the positive end expiratory pressure (PEEP)?

• To prevent alveoli from collapsing

• To enhance oxygen delivery

• To reduce respiratory rate

• To increase tidal volume

Which mode allows the patient to initiate a breath while the ventilator assists?

• Mandatory ventilation

• Spontaneous ventilation

• Assisted ventilation

• Controlled ventilation

What is a common feature of volume-controlled ventilation?

• It raises airway pressure to a set level

• It is less popular than pressure-controlled ventilation

• It is used only in chronic care

• It delivers a specified tidal volume

What is the role of microprocessors in modern ventilators?

• To provide oxygen supply

• To control metering devices and algorithms

• To manually operate the ventilator

• To monitor patient heart rate
