Initial Vent set up Flashcards

1
Q

Determine the pts vents need based on…

A
1. Is the problem restrictive, obstructive, or normal patient lung.
2. Calculate pts. IBW
2
Q

Vent modes for Normal lung mechanics

A
```Use either PC, PRVC, VC to achieve Vt
3-5 ml/kg
--------------------------------------------------------------
1. Use either PC, PRVC, VC, to achieve
Vt 6-8 ml/kg```
3
Q

Most common initial vent mode

A

AC-PC
Or
AC-VC

4
Q

VC

Volume control

A
1. Set sensitivity/trigger 1-3
2. Set Rate 10-20
3. Set fi02 40-60% (100% in Emergency)
4. Set PEEP 0-5
5. Set Vt (based on 3-5 or 6-8 ml/kg IBW)
6. Set flow(V) (40-60) to achieve I:E of 1:2- 1-4
7. Flow pattern=ramp
5
Q

PC pressure control

A
1. Set sensitivity(trigger) 1-3
2. Set Rate 10-20
3. SetFi02 40-60% 100% Emergency
4. Set PEEP 0-5
5. Set pressure limit 15-25 to achieve appropriate Vt.
6. Set I-time .8-1.2 to achieve an I:E of 1:2 to 1:4
7. Rise time(leave set at 1+ (default setting))
6
Q

PRVC (pressure volume control)

A
1. Set sensitivity(trigger) 1-3
2. Set Rate 10-20
3. Set Fi02 40-60% 100% Emergency
4. Set PEEP 0-5
5. Set target Vt
6. Set set pressure limit in alarms 30-40
7. Set I-time .8- 1.2
8. Set rise time
7
Q

SIMV

spontaneous intermittent mechanical ventilation

A

Choose breath type (PC or VC)
Set vent parameters then attach Pt. to vent.
Set Alarms

8
Q

Ventilator Alarm parameters

A

Pressure (PIP) high=10-15
(PIP) low= 5 below

Rate= high=10-15
Low=5 below

Ve=high=+2
Low=-2

Vt=high=+200ml
Low=100ml below

9
Q

PSV (pressure support ventilation)

A

Gets added on to a spontaneous mode.

SIMV applies to spontaneous inspiration only

Used to overcome RAW

Used to achieve spontaneous Vt less than or equal to 5ml/kg

Pressure limited/ patient cycled

10
Q

Auto PEEP (intrinsic PEEP)

A

To determine amount of auto PEEP,
The assess flow versus time graph

Fix by :::

1. Increasing E-time (by increasing flow or decreasing Vt.)
2. decrease rate Or volume
3. Sedate
4. Bronchodilators
