All or part of the breath is

Answer 13

generated by the ventilator

Question 14

Three types of breath delivery timing or sequence are available on current ICU ventilators:

Answer 14

• Continuous mandatory ventilation (CMV)
• Intermittent mandatory ventilation (IMV)

Question 15

All breaths are mandatory and can be volume or pressure targeted; breaths can be timed or pt triggered

Answer 15

Continuous mandatory ventilation (CMV)

Question 16

When the breaths are time triggered the breaths are described as

Answer 16

controlled ventilation (control mode)

Question 17

When the breaths are pt triggered during CMV, the breaths are

Answer 17

assisted ventilation

Question 18

Controlled (time- triggered) ventilation is appropriate only when a pt

Answer 18

cannot make an effort to breath

Question 19

Pt receives a set number of mandatory breaths but can also breath spontaneously breaths between mandatory breath

Answer 19

Intermittent Mechanical Ventilation (IMV)

Question 20

All breaths are spontaneous and pt triggered

Answer 20

Continuous spontaneous ventilation (CSV)

Question 21

VC-CMV is also referred to as

Answer 21

volume- controlled continuous mandatory ventilation (targeted)

Question 22

All breaths are _____________ in VC-CMV

Answer 22

mandatory

Question 23

If the pt triggers the breath it is called

Answer 23

assisted

Question 24

Once thought to minimize WOB DURING mv; Pt receiving this mode of ventilation may actually perform 33%- 50% or more of the work of inspiration

Answer 24

VC-CMV

Question 25

All breaths are timed or pt triggered **pressure** targeted, time cycled. What kind of ventilation is this?

Answer 25

Pressure- Controlled Continuous Mandatory Ventilation (PC-CMV)

Question 26

PC-CMV is also called

Answer 26

pressure- triggered or simply pressure controlled ventilation

Question 27

Answer 27

PC-CMV

Question 28

The maximum pressure limit during PC-CMV is typically set to approximately

Answer 28

+10 cm H2O

Question 29

The operator sets the length of ___________ the pressure level and the back rate of ventilation

Answer 29

inspiration

Question 30

The ____ is delivered by the ventilator is influenced by the ____________ and resistance of the pt's lungs, pt effort and the set pressure

Answer 30

VT; compliance

Question 31

The pt can breathe spontaneously between mandatory breaths at any desired baseline pressure w/o receiving a mandatory breath

Answer 31

Intermittent Mandatory Ventilation (IMV)

Question 32

Involves **periodic** volume - or pressure targeted breaths that occur at set interval (Time triggering)

Answer 32

IMV

Question 33

Three basic modes for providing CSV during MV

Answer 33

- Spontaneous breaths - Continuous positive airway pressure (CPAP) - Pressure support ventilation (PSV)

Question 34

pts can breath spontaneously through a ventilator w/ receiving any mandatory breaths

Answer 34

Spontaneous modes

Question 35

In this mode a continue level of positive pressure is applied to the pt's airway through inspiration and expiration

Answer 35

Continuos positive airway pressure (CPAP)

Question 36
