Vent Exam

Question 1

What kind of Modes are on the vents?

Answer 1

AC (Assist control) and SIMV (synchronized intermittent mandatory ventilation)

Question 2

What type of breath types are there on the vent?

Answer 2

Volume and Pressure

Question 3

What is AC ventilation mode?

Answer 3

Assist control, Takes away work of breathing, easier control of ventilations, specific amount of breath is given.

Question 4

What is SIMV mode on vent?

Answer 4

Synchronized Intermittent Mandatory Ventilation. More comfortable for spontaneously breathing patients. Gives breath if patient does not take the spontaneously breath or pushes off the next breath if they do take a spontaneous breath

Question 5

Cons of AC mode?

Answer 5

Can cause breath stacking and barotrauma, Asynchrony

Question 6

Cons of SIMV mode?

Answer 6

Pressure support must be titrated to help remove work of breathing.

Question 7

What is a volume controlled breath type?

Answer 7

A tidal volume is set based on ideal body weight. 6-8 cc/kg

Question 8

What is a pressure control breath?

Answer 8

A pressure you wish the breath reaches

Question 9

What is the ideal pressures for pressure control breaths?

Answer 9

Ideally 15-25 but should not exceed 30 to avoid trauma.

Question 10

What does Spf stand for?

Answer 10

Total number of spontaneous respirations

Question 11

What does f stand for?

Answer 11

Frequency the total number of breaths the patient has received

Question 12

What does PEEP stand for and mean?

Answer 12

Positive End Expiratory Pressure, Keeps alveoli open and improves oxygenation

Question 13

What does FIO2 stand for and mean?

Answer 13

Fraction of Inspired Oxygen, the percentage of oxygen being administered to the patient.

Question 14

I-time means and stands for?

Answer 14

Inspiratory time, the amount of time a machine controlled breath will take to be delivered.

Question 15

Normal I-Time for adults, adolescents, toddler/school age, infant?

Answer 15

Adult: 1 second, Adolescents: 0.7 seconds, Toddler: 0.5 second, Infant: 0.3 seconds.

Question 16

What is PIP?

Answer 16

Peak Inspiratory Pressure. The pressure in your lungs at the peak of a breath

Question 17

What is the normal range for PIP?

Answer 17

Less than 40 but Ideally less than 30.

Question 18

What is pPlat?

Answer 18

Plateau pressure, Represents the pressure applied to smaller airways and alveoli by mechanical ventilator

Question 19

What Is pPlat’s normal range?

Answer 19

Should be less than 30.

Question 20

What categories are in Lung protective strategy?

Answer 20

Barotrauma, Volutrauma, and Environmental trauma.

Question 21

How to protect against Barotrauma?

Answer 21

Keep pPLAT less than 30.

Question 22

How to protect against Volutrauma?

Answer 22

Keep tidal volumes between 6-8 cc/kg of Ideal Body Weight

Question 23

How to protect against environmental trauma?

Answer 23

Utilize the HME filter or humidified vent.

Question 24

What do you do if you have a high pressure alarm with a high pip but normal pPLAT?

Answer 24

Sedate, Suction, and check for kinks and bends in the circuit

Question 25

What do you do if you have a high pressure alarm with a High pPLAT?

Answer 25

Make sure tidal volume is 6-8 cc/kg per IBW. Raise head 30-45 degrees, and treat based on the lung pathology (Ex. COPD patients, Asthma patients, Pneumonia patients.)

Question 26

What to do when a low peak pressure is alarming?

Answer 26

Check circuit for leaks or tubing disconnect, Check tube cuff inflation, Ensure tube is not dislodged, Ensure adequate tidal volume is set.

Question 27

How to measure IBW?

Answer 27

Males: 50kg + (2.3kg x every inch over 5ft)
Females: 45kg + (2.3kg x every inch over 5ft)

Question 28

What is I:E ratio mean?

Answer 28

Inspiratory expiratory ratio. Inspiratory time vs expiratory time

Question 29

What is a normal I:E ratio?

Answer 29

1:2 to 1:4

Question 30

What does spVTE mean?

Answer 30

Spontaneous exhaled volume.
