Q

T/F

End tidal Co2 is a good indication of late respiratory distress

A

False.

It is an EARLY sign of respiratory distress. If it is outside the 35-45 range, we can tell something is wrong early on.

Q

Why would a sedated patient need to have their ETCO2 monitored?

A

Due to sedation meds they won’t be able to notify us if they are having breathing issues so the filter can help us make sure they are

  • they too can cause resp depression
  • colonoscopy, tee, etc

Q

Your patient has a ETCO2 reading is 34. Their RR is 13. What do you do?

A

You would need to continue to monitor them and check the trends. The range is 35-45. It being 34 is not too concerning right now.
- you can ask them if they are feeling ok

Q

What happens to a patients ETCO2 reading levels if you ventilate them too quickly?

A

Not enough Co2 will be able to build up in the alveoli - which causes a LOWER ETCO2 reading.

Q

What happens to a patients ETCO2 reading levels if you ventilate a patient too slowly?

A

Sort of odd but by ventilating too slowly extra amount of Co2 will be able to build up in the alveoli which will cause HIGHER ETCO2 reading.

Q

Can you get an O2 sat reading on a patient that is coding?

What about end tidal Co2?

A

No, you can’t. They’re not perfusing.

Yes the end tidal CO2 can be read and it can help you see if you’re doing good compressions.

Q

What do you consider if you are consistently getting low Co2 readings?

How can a pulmonary embolism cause a low ETCO2 reading?

Is this perfusion, metabolic, or a psych problem?

A

Think about the perfusion, metabolic, psych problems causing it

A blocked pulmonary artery will cause less Co2 rich blood to return to the lungs and so you can’t breath co2 out

A perfusion issue

Q

How can DKA cause a low ETCO2 reading?

What type of breathing occurs in DKA?

A

DKA involves the body being in an acidosis state. CO = acid. In order to get read of the acid, the body will start to breath rapidly to breath off more Co2 to compensate…… which then turns more slow and labored ultimately leads to LOW ETCo2 levels.

In order to compensate the hyperventilation going on is called Kussmauls = rapid, shallow breathing (like a sigh). The worse the acidosis from dka gets the slower and more labored the kussmauls become due to air hunger.

Q

What is the likely reason someone’s ETCO2 would be high?

A

Respiratory failure of some sort due to not being able to breath off the normal of co2 at first. And it accumulates - so eventually your end tidal volume rises

Q

If someone is going into respiratory arrest which is the best early indicator and why : O2 sat or ETCO2?

A

ETCO2.

You can inhale enough oxygen and still go into arrest due to just being fatigued. The CO2 however doesn’t lie.

Q

what happens to etco2 if the patient is hypo-ventilating?

what happens to arterial co2?

what state does this lead to?

common states that cause this?

Treatment goal?

A

RR breathing is slow so the co2 can not clear out in the lungs so the end product is too much co2 in the alveoli

arterial co2 levels rise too

metabolic acidosis

head injuries and opioids OD

Increase depth and rate of RR to help them blow off all the CO2.

Q

What is an RSI?

What nature of issue would we use this?

A

Rapid sequence intubation where you can give PARALYTIC agent to deploy airway
- used for emergencies because it allows for a quick intubation

34
Q

Reasons to use RSI?

A

It is quick intubation
Helps with perfusion
Decreases aspiration, combativeness, and injury to us actually paralyzing them

35
Q

Reasons we won’t give an RSI to specific?

A

Comatose patients
Cardiac arrest patients

Bc the patient is asleep or the needs is irrelevant

36
Q

Why do we use paralytic agents?

Likely candidates we use this?

What meds do we give NEED to give with these?

A

Intubation success and ease

Post code, hypothermia, severe trauma since body needs to heal
- all to prevent hardship when intubating a patient

Sedative agent such as midazolam (versed) to keep the pt calm and sedated
- remember a paralytic only paralyzes a patient . It doesn’t knock them out

37
Q

How do we ensure the patient is at the right level of paralyticc?

A

Use of the train of four (TOF)

Metal prongs emit electricity and place them on radial artery - and observe for twitches of the thumb.

38
Q

How many train of four twitches do we want when measuring the paralytic effectiveness

What is our back up measurement if we don’t get anything on the radial artery?

What if we get a zero?

A

We want 2/4 twitches when holding medal at the radial site

Move to temporal site and check for 2/4 twitches of the eye

Call physician and then you will decrease the amount the paralytic drip is running

39
Q

List the neuromuscular blocking drugs/PARALYTICS in alphabetical order

A 
Curare
Mivacurium
Pancuronium
Rocuronium
Succincylcholine

You’ll be needing these if your patient is wide awake for a intubation. Just know these aren’t for sedation in intubation

40
Q

What do we do before intubation?

How long should intubation attempts take? What if it takes too long?

A

Pre-O2 the BVM mask at 100% for 3-5 minutes

Less than 30 seconds

  • you will need to remind the crna about this and watch o2 levels
  • You need to bag the patient with 100% o2 and ventilate them in between
41
Q

What happens after intubation?

How do we check where it is?

A

Cuff is inflated by resp therapy and confirm placement of the ET tube
- all while pt is being manually ventilated btw

Check with xray
- and also check the ETco2 levels

42
Q

After intubation how do you measure the end tidal co2 to confirm placement?

Purple meaning?

yellow?

A

Deliver 6 breaths and then measure

Purple means no exhaled co2 detected = bad

yellow co2 is detected = successful

43
Q

Can you detect CO2 during cardiac arrest or other code situations?

A

Not exactly because there’s no perfusion. BUT you can if you are doing compressions

44
Q

T/F

ETCO2 can detect right main stem intubation

A

False. it cannot.
a very common misplacement actually
- instead, check for bilateral lung sounds.if they aren’t equal then the may be a stem placement. then get xray

45
Q

You use a colorimetric detector to check to see for proper trachea tube placement. You get a positive result . Should you immediately think there is proper placement

A 
No- you can get a false positive due to acidity from stomach and acidic drugs like epinephrine. 
Put all the pieces together to check 
- auscultate
- colorimetric/other co2
- xray
46
Q

T/F

Incorrect tube placement on a patient is not emergent

A

false. It is an emergency

47
Q

Main goal when there is an incorrect tube placement ?

What do you need to support?

A

Stay with patient and maintain the airway with BVM and 100% oxygen

support ventilation

48
Q

When there is an incorrect tube placement , what should you prepare for?

What do you try to monitor?

A

Prepare for re-intubation

Vitals, ekg, and pulse ox

49
Q

How will you as a nurse be maintaining correct tube placement?

How often should you monitor the et tube?

A

You will need to know the proper tube size and french placement always. (22@ the lip)

2-4 hours

50
Q

What if you notice the et tube is slipping?

How do we prevent the pt from pulling et tube out?

A

Let RT know so they will tape it for you if it is slipping
- best with 2 people so you may have to assist

Use of soft limb restraints can keep the patient from pulling the tube out

51
Q

T/F

Tubing always stays in place if a patient is moving

A

False.

You need to check and support the tubing if the pt is moving because it can come out.

52
Q

Common injuries that occur due to ET tube placement?

A

Lips, teeth, orapharynx, and vocal cords

- so assess for these

53
Q

What is a possible risk due to the gag reflex in intubated patients?

A

Vomiting and aspiration

54
Q

What nerve can be triggered by intubation?

A

Vagus nerve which leads to bradycardia

- watch vitals the entire time

55
Q

Common misplaced intubation locations?

A

Esophageal and right main stem intubations

- if this is the case, the lung sounds won’t be equal

56
Q

When you xray for intubation placement where should the tube be

A

3-5 cm above the carina

57
Q

Why do you need to check the cuff when dealing with an ET tube?

A

Check for proper cuff inflation because there could be leaks or sounds the patient makes
check o2 and if it is trending down, call RT to check the cuff inflation.

58
Q

What do you need to check for when it comes to stabilization of the Et tube?

A

Make sure it is taped properly around the mouth so no gas escapes!

59
Q

What do we need to check for skin integrity wise due to the et cuff?

how do we prevent this?

A

It can cause pressure and skin injuries

Cuff pressure is measured and recorder on routine basis
utilize RT if you think there might be a leak

60
Q

How do we maintaining tube patency?

What are indications to suction?

A

Assess need for suctioning because we do not suction routinely - bc we don’t do this routinely. Can cause coughing and affect abgs

  • Decrease in o2 sats and secretions to indicate the need to suction
  • Sudden onset of resp distress
    Listen for lung sounds of fluid or crackles
  • An increased respiratory rate and so they cough - which can lead to monitor going off.
61
Q

Open suction technique

A

Using oral suction to get around the tube

62
Q

close suction technique

A

suctioning that is inside the et tube where you push the button and draw out the suction tubing

  • enclosed in plastic
  • the one you did at capstone first day
  • safer for you since there is less exposure of secretions
63
Q

What should you do before suctioning?

How long should suctioning last?

Vital to watch?

A

Hyper-oxygenate before hand
- but if their o2 sats are high and good then you don’t always need to

Less than 10 seconds

Watch 02 levels

64
Q

What should suction pressures be limited to?

What should you avoid while suctioning?

A

less than 12o mmhg

Avoid overly vigorous catheter insertion

65
Q

Reasons why secretions could be thick

How to fix this?

A

Not getting enough liquid

Call for IV fluids
Supplemental humidification

Postural drainage

Turning patient every 2 hours

Percussion to break everything up

66
Q

Potential complications that may occur while suctioning

A

Hypoxia because it blocks their airway

Bronchospasm

Increased ICP

Dysrhythmias (pvc)

BP changes (up or down)

Trauma to airway (bleeding - call if acute!)

Infection!!! (Due to sores or breakdown)

67
Q

Practice Q:

What are indication for suctioning patient?

A

Bucking the vent

Their o2 goes down

Secretions

Resp distress all of a sudden

68
Q

How often should you provide oral care to your ventilated patients?

A

Oral care is done every 2 hours. Always!

Do it more often if needed

69
Q

Why would a ventilated patient need to be on DVT prophylaxis?

What med can we use?

Nonmed intervention?

A

This patient is lying in bed 24/7. We need to make sure they don’t throw a clot.

Heparin drip
SQ Lovenox

SCD

70
Q

We need to prevent stress ulcers in ventilated patients. How would you do this?

A

The patient will be ventilated and be laying down. So we turn them q2hrs.

71
Q

How do we usually feed ventilated patients?

A

Gut feedings w protein (if diet allows). And it is super important bc it helps them heal.

72
Q

What should the bed angle be at for a ventilated patient ?

What about for tube feedings?

A

Elevate HOB between 30-45 degrees

30-45 for tube feedings too

73
Q

What are navel drugs again?

Is there a golden rule set dose for NAVEL drugs? Route difference?

A

Drugs that can be given with ET tube that are lipid soluble

Nope no set amount but the the dose is 2-2.5x higher than IV/IO

74
Q

Since NAVEL drugs are liquid soluble, how much do we mix them with?

What do we do once we are done giving the NAVEL meds>

A

5-10 mLs of NS

Do 1-2 ventilations
