Why Multiple Choice Questions on Mechanical Ventilation?

In order to give high quality patient care all health professionals near the bedside must learn about the functions of ventilators, the limitations and advantages of different ventilator modes, and the way a patient adjusts to ventilator. Knowledge about these aspects empower them to promptly identify problems and help them to take corrective action.

An artificial airway like an endotracheal tube is used in the following type of ventilation

  • Positive Pressure

  • Negative pressure

------------------------------------

Answer: Positive Pressure

Pressure is applied to the abdomen and thorax to draw air into the lungs through the upper airway in the following type of ventilation

  • Positive Pressure

  • Negative pressure

--------------------------------------

Answer: Negative Pressure

Iron lung ventilators used after the polio epidemics in the first half of the 20th century belongs to

  • Positive Pressure Ventilation

  • Negative pressure Ventilation

--------------------------------------

Answer: Negative Pressure

One of the following modes of ventilation “locks out” the patients’ efforts to breathe

  • Controlled Mandatory Ventilation

  • Synchronous Intermittent Mandatory Ventilation

  • Assist Control Mode

  • Pressure Control Mode

------------------------------------------

Answer: Controlled Mandatory Ventilation

A step down Intensive care Unit. It does not have Mechanical Ventilators

One of the following modes of ventilation has the risk of patient getting respiratory alkalosis

  • Controlled Mandatory Ventilation

  • Synchronous Intermittent Mandatory Ventilation

  • Assist Control Mode

  • Pressure Control Mode

------------------------------------------

Answer: Assist Control Mode

The mode of ventilation which allows the patient to breathe spontaneously at his or her own respiratory rate and depth between the ventilator breaths is

  • Controlled Mandatory Ventilation

  • Synchronous Intermittent Mandatory Ventilation

  • Assist Control Mode

  • Pressure Control Mode

------------------------------------------

Answer: Synchronous Intermittent Mandatory Ventilation

Minute ventilation is equal to

FiO2 X PEEP

FiO2/PEEP

Tidal Volume X Respiratory Rate

Tidal Volume/Respiratory Rate

---------------------------------------------

Answer: Tidal Volume X Respiratory Rate

Which are the Ventilator Parameters adjusted to maintain the optimum Minute Ventilation?

  • FiO2 and PEEP

  • Tidal Volume and Respiratory Rate

---------------------------------------------------

Answer: Tidal Volume and Respiratory Rate

Which are the Ventilator Parameters adjusted to maintain the optimum oxygenation?

  • FiO2 and PEEP

  • Tidal Volume and Respiratory Rate

---------------------------------------------------

Answer: FiO2 and PEEP

One of the following modes of ventilation reduces the work of breathing by overcoming the resistance created by ventilator tubing.

  • Controlled Mandatory Ventilation

  • Synchronous Intermittent Mandatory Ventilation

  • Assist Control Mode

  • Pressure support Mode

-----------------------------------------------

Answer: Pressure support Mode

Difference between CPAP and BiPAP

CPAP is essentially a constant PEEP. BiPAP is CPAP plus Pressure support.

Both these modes have shown to reduce need for intubation and mortality among COPD patients.

CPAP and BiPAP modes are usually used

  • In conjunction with bronchodilators and steroids

  • to delay intubation

  • as a weaning protocol

  • all of the above

------------------------------------------

Answer: All of the above

Which one of the following modes of ventilation is triggered by time, limited by pressure and affects inspiration only?

  • Controlled Mandatory Ventilation

  • Synchronous Intermittent Mandatory Ventilation

  • Assist Control Mode

  • Pressure Control Mode

------------------------------------------

Answer: Pressure Control Mode

There can be variations in the minute ventilation in one of the following modes of ventilation as the respiratory rate and tidal volume is determined by patient

  • Controlled Mandatory Ventilation

  • Synchronous Intermittent Mandatory Ventilation

  • Pressure Control Mode

  • Pressure Support Mode

------------------------------------------

Answer: Pressure Support Mode

Which of the following conditions require a higher PEEP to be applied in recruiting collapsed alveoli?

  • Asthma

  • Acute Respiratory Distress Syndrome

  • Bronchietasis

  • Emphysema

-----------------------------------

Answer: Acute Respiratory Distress Syndrome

One of the following is a risk of keeping high PEEP

  • Hypotension

  • Hypertension

  • Hyperthermia

  • Hypothermia

-------------------------------------------

Answer: Hypotension

Hi Bethany

I am glad that that answer could be of use to you.

You are most welcome for any further clarifications :)

Thanks for the reply! I was just curious as to if there were some distinguishing features between the two. Being new to the field, it's great to have a perspective on terminology that may not be taught anymore, but that is still thrown around. There's nothing worse than talking to a doctor and hearing a term you aren't familiar with in the hospital atmosphere. Thanks for the learning opportunity.

Hi Bethany

Both terms mean the same. "controlled mechanical ventilation" is relatively an older terminology. I mean when we were (older generation) were students, we were taught is "controlled mechanical ventilation or "controlled mandatory ventilation.

Now you are using the term "continuous mechanical ventilation"

The characteristics are same

However, now a days we hardly see this mode being used

It was a very common mode for post neuro-surgical patients in the 90s

Patients were given sedation and muscle paralysing agents along with CMV

I enjoyed your MCQs, however I'm curious about the term "controlled mechanical ventilation." The term I am familiar with is "continuous mechanical ventilation" and have always been taught that it is interchangeable with assist-control. Just trying to compare my knowledge base to yours! :)
