Q

PEEP

A

Positive and expiratory pressure ( 5-10 cm H2O)

Can go all the way up to 15 on high peep but sometimes can be at 5 to keep alveolar open and to keep it from collapsing during expiration

Q

Barotrauma

A

When increased airway pressure distends the lungs and possibly ruptures fragile alveoli or emphysemtous bless ( pt with non compliant lungs such as COPD) at greater risk for this

25
Pt is coughing
Continue to monitor
26
Bronchospasm
Assess for nonproductive consistent cough , give breathing treatments
27
Pulmonary edema
Assess lung sounds and ETT for fluid ; suction needed may need to be placed prone and given diuretics
28
Decreased lung compliance
Assess lung sounds RR, BP and sao2 , notify RT and physician , ventilator mode may need to be changed
29
ETT cuff pressure should be at
<25
30
If cuff pressure is too low
Puts pt at risk for aspiration, unintentional excubation, and pt can talk to us ( we dont want them to)
31
If cuff pressure is too high
It can cause tracheal necrosis
32
Chest xray reveals what about ETT
3-4 cm above carina
33
What should the capnometer reveal
The color yellow to indicate the presence of CO2 But the purple is a no no
34
When we sunction the pt what should we do when it comes to the carina
It already sits about 3-4 cm and when you sunction , barely touch it ..it can cause a cough so that’s how we know when we are there
35
What is the obiturator used for?
If the trache falls out , we can emergently place this to maintain airway.. it is emergency and cold blue situation
36
What is the first thing we do when there is a change in the condition in the pt
Assess the patient
37
What can we trouble shoot if pt seems like they are having a hard time breathing with a trache
May have mucous plugs in inner cannula and suction .. then sit and watch to see if it worsens
38
How often to change inner cannula for the trache
Every shift or PRN
39
How long should you sunction?
10-15 seconds*** at most 10 seconds
40
How often to do oral care?
Every 4 hours
41
What indications for suctioning
Coughing, increase resp, o2 sat down , tachycardia, restless, seeing plegm or hear it when auscultation
42
Restraints for safety
Restraint release q2 hours and skin assessment Do you have an order? Are you doing ROM ? Are you keeping up with the order?
43
Pharm surround mechanical ventilation
Vasopressors Additional fluid Bronchodilator Paralytics Sedatives
44
LEAN drugs
Lidocaine Epinephrine Atropine Narcan
45
Patient safety ETT or trach
Ensure tube is secured Keep tube patent Verify maintain placement Monitor resp status Bag valve mask in the room Keep scissors airway from external balloon
46
How do we make sure air way is what it needs to be with trach
Auscultation , and cuff pressure less than 25
47
What should you always have at the bedside or when you take the pt anywhere
BVM
48
Why should we restraint be placed?
Danger to self and combatitive
49
What should we ensure before suction?
Validate and make sure sunction is working (80 -100 ml of pressure) And you have pre oxygenated the patient with 100%
50
Suction order
Check suction make sure its working Pre oxygenate pt Insert Catheter suction And clear for the next use
51
What should we keep in mind with someone with intracranial pressure if you need to turn them and suction
Give them a break in between
52
Suction can be seen in
Ventilator , trach , ETT
53
Oxygenation toxicity
Chest pain Dyspnea , uncontrolled coughing long period
54
How can we decrease co2?
Increase RR and or tidal volume
55
What if we are having trouble with pao2?
Increase fio2 ( amount of o2) Or increase the peep
56
Important for the nurse in positive pressure ventilation
Verify setting Assess pt Ensure pt safety Trouble shoot as needed Monitor for ABGs
57
A/C ventilation
Pt can’t breath slower than what is set If it is set at 500 ml and they take a spontaneous breath it will sense and make sure breath goes to 500 ml If pt is doing good they may bring down the breaths per min to see if they can do more breaths on their own
58
What is an art line used for
ABGs lab work , blood sugar, vasopressor NEVERRRR for medications
59
The inflated cuff of an ETT
When inflated produces a seal between the trachea and the cuff to prevent aspiration and ensure delivery of a set tidal volume when mechanical ventilation is used.
60
Medications ETT intubations
Paralytic, sedative, ( propofol , medazalam versed)
61
What patient is not for bipap
Shock Altered loc Increase airway secretion
62
Fio2 >50% for more than 24-48 hours
Can cause oxygen toxicity
63
S/s of o2 toxicity
Restlessness, Dyspnea, chest discomfort , fatigue , atelectasis
