Key points #1

Question 1

The difference between patient triggering and spontaneous
breaths.

Answer 1

Patient Triggering: Movement of diaphragm causes machine to initiate breath

Spontaneous: Pt controls all the variables per breath , breathing on their own with ET tube in

Question 2

Types of Breaths on Vent

Answer 2

Spontaneous
Mandatory
Assisted

Question 3

What is trigger sensitivity?

Answer 3

Setting on vent adjusted to trigger breath for minimal wob

Question 4

what happens if trigger sensitivity is set wrong

Answer 4

It can lead to asynchrony and hyperinflation

Question 5

what can set off auto trigger if sensitivity is turned up too high?

Answer 5

Hyper dynamic heart beats, excess water in vent circuit, pt movement

Question 6

Indications for MV

Answer 6

Apnea
Impending Resp Failure ( worsening condition)

Prophylactic Vent support ( head injury, major surgery, shock, trauma)

chronic resp failure: significant pulmonary weakening

Question 7

Contraindications for MV

Answer 7

Pt code status : DNI, DNR, UNTREATED tension pneumothorax, pt ability to wean,
other non invasive options: BIPAP

Question 8

What kind of inspiration and expiration HFOV is

Answer 8

An active process

Uses small Vt 50-250mmL
High frequencies ( 3-15 ) 60

Question 9

Know how to solve for IBW

Answer 9

50kg ( 2 x inches over 5ft)

Question 10

Pressure support

Answer 10

2-6 cm h20

helps trigger ventilation

Question 11

Trigger Variable

Answer 11

parameter that starts insp phase of positive breath

Question 12

control/target variable

Answer 12

PRIMARY variable vent adjusts to achieve inspiration

Question 13

Limit Variable

Answer 13

establishes a maximum value that a variable can reach during insp

Question 14

cycling variable

Answer 14

variable that ends insp phase of + breath

Question 15

what is the alarm for peak

Answer 15

10 +- 40 safe

Question 16

starting pressure for peak

Answer 16

5-6

Question 17

staring vent settings

Answer 17

Vt 6-8 ml/kg of ideal body weight
rr : 8-12
peep: 5-8 increase intermittently

Question 18

ACVC

Answer 18

sets desired Vt trigger peep fio2

Question 19

ACPC

Answer 19

Sets ITIME mandatory rate insp pressure limit peep

Question 20

Vent modes are Ac, SIMV, spontaneous modes

Question 21

VC SIMV

Answer 21

sets

Vt
mandatory rate
peak insp flow
pressure suppoerb

Question 22

PCSIMV

Answer 22

sets
Itime
mandatory insp rate
pressure support
insp pressure limit

Question 23

Pressure Triggered-

Answer 23

The ventilator detects a pressure drop at the proximal airway and begins the inspiratory phase.

Question 24

Flow-Triggered-

Answer 24

Flow-Triggered- The ventilator begins inspiration when a change in flow is detected.

Question 25

time Triggered

Answer 25

Time-Triggered- The start of inspiration flow due to a preset time interval

Question 26

Volume Triggered

Answer 26

Inspiration is initiated when the ventilator detects a small change in volume in the patient circuit during exhalation

Question 27

Manual Trigger

Answer 27

Manual-Triggered- The therapist presses a button or icon on the user interface which initiates inspiration
