1

What type of alarms?

1. high pressure
2. low pressure

2

High pressure alarms mean...

the machine is having to push too hard to get air into the lungs

-increased resistance/pressure

3

Most common reasons for high pressure alarms...

HOLD

high=obstruction

1. kinks---unkink it
2. water condensing in dependent loops---empty it
3. mucous secretions in airway---TCDB, suction

4

Rule for suctioning

ONLY AS NEEDED

when they aren't able to clear it by TCDB

5

So...in what order would you assess an obstruction?

1. unkink
2. empty water
3. TCDB
4. suction

6

low pressure alarms mean...

the machine isn't working hard enough...its too easy to get air into the lungs

-decreased resistance

7

Most common reasons for low pressure alarms...

HOLD

low=disconnections

1. main tubing---reconnect (above waist)
2. O2 sensor tubing---plug back in, black coated wire at site

8

If your patient is in respiratory alkalosis, what would you do to ventilator settings?

lower the settings

they are over ventilating, settings are too high

9

If you patient is in respiratory acidosis, what would you do to the ventilator settings?

turn up the settings

they are under ventilating, settings are too low

10

Doctor gives an order to wean patient off the ventilator in the AM, 6AM ABGs show your patient in respiratory acidosis...what do you do?

call the physician, hold order

-pt is under ventilating on the ventilator..do not want to take them off

11

Doctor gives an order to wean patient off the ventilator in the AM, 6AM ABGs show your patient in respiratory alkalosis...what do you do?

-follow order, wean ventilator

-pt is over ventilating with ventilator, so safe to decrease settings

12

If cause of the alarm cannot be found...

discontinue and manually vent your patient

13

When are ABGs reordered after setting change in weaning protocol?

1 hour after setting change

14

To prevent pneumonia on ventilators..

reposition q2, oral care q4, HOB 30

15

Hyperoxygenation prior to suction is used to...

prevent arrhythmias and oxygen desaturation
