Q

List the symptoms of patient with a high Co2.

What does the high CO2 do to BP?

What does this lead to?

A

fatigue, headache, confusion

If you have too much co2, your vaso will vasodilate so BP drops

Fluid retention
&
Can lead to kidney and brain issues

Q

What happens to vessels if co2 is low?

What happens to the HR next?

A

the vessels vasoconstrict

HR increases to get more perfusion done
and sometimes the perfusion isn’t enough for peripheral body parts

Q

Your ventilated patients CO2 levels are high. What nursing intervention will you consider doing before calling the doctor?

A

Suction secretions bc these can block the Co2 from exiting

Check their o2 sat
- remember how to power-shoot if this is off

19
Q

What should the HOB be at for a ventilated patient?

When we assess the patient’s lungs, what are we assessing for?

A

HOB at 45 degrees
- to avoid aspiration & pneumonia

Assess for crackles

20
Q

before suctioning what is a good intervention to do on the mechanical vent?

A

hyperventilate so they don’t de-sat

21
Q

You need to reposition your vented patient. Since they’re ventilated, what should you do?

A

Hold the tubing in place so that it doesn’t accidentally come out.

22
Q

You hear the high pressure alarm go off for the vented patient.
What does it mean if it goes off?
What do you do?

Your vented patient begins to cough. What do you do?

A

There is a blocked airway or occlusion.
Or something more serious like a Tension pneumothorax

You should always check and see why it is going off.

Reassure them and tell them to cough. Stay with them & talk them through it.

23
Q

What does it mean when you hear a low pressure alarm go off on the ventilator?

What should you do if you hear it?

A

The vent didn’t reach the pressure it needed to be at or exhale wasn’t measured properly.

Check tubing and wipe away any condensation.

24
Q

You hear alarm go off on the mechanical vent. What should you do in order?

What should you make sure is in the room at the start of the shift?

A
  1. Check the patient first.
  2. Check the tubing.
  3. Call RT
  4. Bag pt with ambu bag

Ambu-bag

25
Q

How can you tell theres disconnected tubing or an air leak

What are some common places for leaks?

A

You can hear the patient begin to grunt or whisper with the tube in low o2

Cuff, connections, drain & access ports

26
Q

How do you document for tube on ventilated patients

A

ETT location = 8F , 22 cm @ the lip

so 8 is the the size of the tube’s gauge
22 cm is how far in

27
Q

what is a pneumothorax

Types of degrees?

main intervention/fix?

A

collapsed lung - due to air leaking between lung and chest

Pneumothorax can be complete or partial

chest tube!

  • nclex q
  • assess it by making sure it is secure.
  • check tubing
28
Q

What does P.E.E.P. stand for?

What if the effect of PEEP?

A

positive end expiratory pressure
- it is a setting on a ventilator

Effect of peep is to supply pressure to the alveoli in the lungs so they never have to close all the way. it makes gas exchange easier

29
Q

Where will the PEEP setting be located on the monitor?

Avg PEEP value

what is the overall range a PEEP setting can go to if the lungs are “stiff” (meaning they have issues like ARDS or acute respiratory distress syndrome)

A

The setting will be on the bottom ribbon (actual pull will be on the top ribbon)

PEEP of 5cm H20

Between 8-12 is common but up to 20 of H20 if the lungs are too stiff to keep pt comfortable at 5
- higher peep, sicker the patient

30
Q

What does the Tidal Volume setting on the monitor represent?

Which ribbon will this be for the patient is pulling?

A

Amount of preset air volume of o2 and air that can is set to move in and out of the lungs

top ribbon
- settings from pulm. will be on bottom ribbon

31
Q

What is vital capacity on the monitor mean?

what is the constant value for this?

A

Total of the maximum volume that can be inhaled and exhaled in single breath

trick question. not every breath will give you the same tidal volume.

32
Q

What is F.I.O2?

trend

what aspects help determine this

A

It is the amount of o2that the vent delivers
- percent or number between 0 and 1

sick people need more fio2

2 abgs
pulse ox

33
Q

What is ACVC setting on the vent?

Where is the symbol on the monitor?

A

Stands for assist control meaning every breath is supported so the vent does all the work (regardless if the pt can breath a lil on their own)

C on top ribbon

34
Q

Good reason a patient will be on the ACVC (all the work) vent setting?

A 
Recently resuscitated 
ARDS
paralyzed or sedated
- since they cant consciously breath
- not the same thing tho
35
Q

What is Pressure Support setting on a vent?

Can you be on pressure support and acvc at the same time?

A

Provides pressure to give the patient that extra push to draw in breath
- back up for peep

no pressure support and acvc cannot work at the same time

36
Q

What do you need to anticipate if a sedated patient wakes up from you stopping their med drips?
why do we need to calm them ?

A

They will try to pull out their tubing! don’t let them.

  • due to panic
  • anxiousness affects breathing
37
Q

FIO2 meaning

You increase FIo2 on your patient. what happens to pO2 and Co2

A

FIO2 is the amount of oxygen the vent delivers

po2 increases*
no change for Co2

38
Q

PIP increase? idk if we talked about this yet

A

…

39
Q

Tidal volume meaning

If you increase tidal volume on the vent, what happens to pO2 and Co2

A

Set amount of air that moves o2 in and out of the lungs

co2 decreases *
po2 increase or no change

40
Q

What happens to pO2 and Co2 if you increase peep?

A

Peep is pressure blowing up alveoli w air so

increased o2

41
Q

if you increase the RR on the vent what happens to the pO2 and Co2

A

Co2 will decrease bc you breathe it off

o2 increase or no change

42
Q

What happens to pO2 and Co2 if you increase MAP

A

the pO2 will increase

Co2 most likely decreases

43
Q

What is I-time?

norm?

A

Inspiratory time set for patient to inhale and exhale

0.8-1.2 seconds

44
Q

If vent patient ABG returns with a high CO2 what do you anticipate ?

A

You will be trying to get the co2 lowered.

And to do that, you can increase the RR to breathe off the acidic co2
