A
95-97%: children and adults
91-95%: neonates
>60%: cyanotic heart disease
17
Q
Abnormal O2 saturations
A
85-90% indicates moderate to severe hypoxia
Below 85% indicates severe to life threatening hypoxemia
Position them first to see if that helps then suction, then tweak oxygen and maybe give them less
18
Q
When not to do CPR
A
DNAR order
Signs of irreversible death (rigor mortis, decapitation, dependent lividity)
No physiological benefit can be expected because the vital functions have deteriorated despite maximal therapy for such conditions, such as progressive septic or cardiogenic shock
Withhold attempts to resuscitate in the delivery room is appropriate for newly born infants with confirmed gestation < 23 wk or birth weight <400g (Anencephaly or confirmed trisomy 13 or 1)
19
Q
When to stop CPR
A
Normal pulse established
Normal respiratory rate established
Obvious signs of death are apparent
Asystole persist for >20 minutes in the absence of a reversible cause
20
Q
Termination of Resuscitation: Neonate: Termination
A
Occurs with parental agreement: Withhold resuscitation for conditions associated with high mortality and poor outcome: gestation, BW, congenital abnormalities, uncertain prognosis with borderline survival and high morbidity rate, pulse is high, chromosomal or anatomical defects is unlikely to result in survival or survival without extreme disability
21
Q
Termination of Resuscitation: Neonate: Discontinue resuscitation
A
Infants with no signs of life after 10 minutes of continuous and adequate resuscitative efforts (per MD order)
22
Q
Termination of Resuscitation: Child
A
Guidelines for resuscitation termination for children are unreliable
Depends on situation, diagnosis and parental wishes
Children can survive prolonged efforts if: the collapse was witnessed, bystander performed immediate CPR, Early professional treatment ar initiated
23
Q
Organ donation
A
Individual donor can save up to 8 lives through organ donation and tissue donation
Skin is used to treat burn patients and individuals with cancer, bone can be used to treat orthopedic injuries and cancer patients

28
Disaster plan: Personal plan
```
Where will you go
What is your route
Who will pick up the children/pets
Where is meeting place
Emergency travel kit?
Have extra supplies of medication
```
29
Disaster plan: Professional plan
```
Know your facilities policy and procedure for emergency/disaster situations
Protocols
Escape routes
Form of communication, CoC?
Patient evacuation procedures?
```
30
Disaster plan: Community plan
Map of city?
Escape routes?
Shelter in place sites?
Neighbors in need? Elderly? Those with physical and mental disabilities
31
Nurse responsibility in a disaster
Be professionally and personally prepared
Know that you will be called upon and make arrangements with family for absence
Be aware of ethical issues you may encounter when you face patient care decisions
Protect the patient, get them transported to a safer area, crowd control, and triage
32
Weapons of mass destruction
```
Chemical
Radiological
Biological
Nuclear
Explosive or Enhanced conventional weapons
```
33
Disaster preparedness: Know what pt was exposed to
So we can triage
Is it contagious
Precautions?
34
Disaster preparedness: Better natural resistance to aerosolized biologic or chemical agents
Adults
Children and babies are very vulnerable due to curiosity, small, and have sensitive skin that needs extra protection
Children also breath faster
35
Disaster preparedness: Who requires more resources
Children
36
Disaster preparedness: Why are drug formulation availability limited for pedi?
No FDA approval
Limited testing done on infants and children since it requires the parents approval, they are often reluctant to have child on unknown drugs
37
Disaster preparedness: Are children desirable targets t terrorist attacks?
Yes
School especially because they know that children are our most precious asset and such an attack would psychologically cripple the population
Schools are defenseless and unprepared
Tend to gather in large groups
Have natural curiosity and seek out objects of interest
They evoke extreme emotional reaction by rescuers and the public
38
Appearance: Color or Circulation
Should be pink, means good perfusion
Pale or white is a sign of lack of O2, poor perfusion form vasoconstriction because the blood is being shunted to the vital organs away from the extremities. Hands and feet are cold. Next -Blue
Blue is cyanosis- meaning that all compensatory mechanisms have failed
39
Appearance: Eye contact
Are they looking at you?
Are they looking past you?
Glass eyed?
40
Appearance: Speech or cry
If you're doing something and they don't respond, its very concerning
Normal: high pitched, weak, are they crying?
Consolable, Inconsolable?
41
Appearance: Motor activity
Flaccid or limp?
42
Appearance: Increased or decreased RR
Pulse is <60/min, and there are signs of poor perfusion (pallor, mottling of the skin, cyanosis) despite supplemental O2 then start compressions
43

Respiratory distress
```
Can still help them!!!
Airway open and maintainable
Tachypnea
Increased respiratory efforts
Grunting
Retractions- substernal/intercostal
Nasal flaring
Abnormal airway sound (wheezing, stridor)
Tachycardia
Pale to cool skin
Change in mental status (anxiety, agitation)/ GCS
(manage immediately!! Child will rapidly progress into respiratory failure, shock, and arrest)
```
50
Respiratory Failure
```
Trying to prevent!!
Airway not maintainable (NC or facemask will not help, NEED ET)
Bradypnea
Apnea
Decreased or no respiratory effort
Poor to absent distal air movement
Bradycardia
Cyanotic
Stupor
Coma
Flaccid muscle tone
Unresponsive
```
51
What is Cardiac arrest
Abrupt cessation of normal circulation of the blood due to failure of the heart to contract effectively during systole- cardiovascular collapse is impending shock
Cessation of clinically detectable cardiac mechanical activity
52
Cardiac Arrest: Characterized by
Unresponsiveness, apnea, absence of detectable central pulses
53
What to obtain when a child experiences cardio-pulmonary arrest
```
Age
Recent illnesses
Previous medical problems
Current meds
Recent trauma
Time of day of incident
Location of child during incident
Access to toxins/medicines/poisons
Access to potential foreign bodies
Length of downtime- affect recovery
Was CPR initiated and for how long?
Overall appearance
ABC
Vital signs
SpO2
LOC/GCS
Tracheal deviation
Subcutaneous air/crepitus
Pupillary response
Evidence of trauma
Surgical scars
```
54
Evidence of prolonged time since death
Rigor mortis
Dependent lividity
Corneal clouding
55
Effective CPR prolongs:
Presence of Vfib and improve chances that a shock will terminate this lethal rhythm
Need electrical activity to shock the heart
56
Compressions
30-2 and 100 compressions a minute
57
Reserved O2
Many patients have left over O2 in their blood and lungs from their last breath so we can take advantage of that and do compressions until help arrives
58
Where to palpate pulse on: Infant <1 yr
brachial artery
59
Where to palpate pulse on: Infant >1 yr-adolescent
Carotid artery
60
Children HR <60
Start compressions
61
Children Respiratory rate <10/gasping/apneic
Bag mask ventilation (rescue breaths)
62
What to do first with unresponsive child
Assess unresponsiveness (gently stimulating them)
Check breathing
Quick check for pulse
Call for help (code button, call out for code cart)
Position for CPR (hard flat surface, backboard, CPR lever)
No pulse, poor perfusion (HR<60 start compressions)
Rescue breaths (gasping isnt enough air for perfusion, slow breathing arent enough for perfusion)
63
Witnessed arrest vs. didnt witness arrest
Witnessed: call for help then begin compressions
| Didnt witness: initiate compressions and continue with rescue breaths for 5 cycles (2 minutes) then call for help
64
Neonatal arrest
Predominantly axial in nature, so the ABC resuscitation sequence with 3:1 ratio of compressions to ventilations has been maintained, except when etiology is clearly cardiac
65
Circulation: Compression to ventilation ratio for Infants and children: Single rescuer
30:2
66
Circulation: Compression to ventilation ratio for Infants and children: 2 HCP rescuers
15:2
67
Compressions on an infant <1yr
Use 2 thumbs-hands encircling the chest technique, midtesternal or 2 fingers midsternal just below the nipple line
Compress the chest about 1.5 in
(alone: use 2 thumbs, with help: use 2 fingers)
68
Compressions on a child 1-8yr
Use the heel of one hand to compress the lowe 1/2 of the sternum
Compress about 2 inches
69
Compressions on >8yr
Use adult method, 2 hands at a depth of 2 inches
70
Compression techniques
Arms straight, bent over give good force
Ribs break... we want them to breath and live
Effective compression (hard and fast)
Rate: 100/min
Depth: 1.5-2 inches
Always allow for complete recoil of the chest
Compressions must not be interrupted except for ventilation
Re-evaluate after 5 cycles or 2 minutes
Know that the rhythm on the stip will not be accurate
71
Airway
Maintain patent airway
Use head-tilt chin lift (if no cervical spine injury suspected)
Use jaw thrust (if possible cervical spine injury)
Open mouth, visually inspect and suction
Vomitus or foreign material may obstruct the airway (clear it out)
Nasopharyngeal or Oropharyngeal airway is used/placed
Position to help visualization, and ventilatilation
Sniffing position
72
Airway: Most common cause of upper airway obstruction
tongue
73
Sniffing Position
Theres a towel under patients neck to get better visualization of airway, and nose is angles up like their sniffing
For older children, can use a towel behind the neck to extend it for a good head tilt chin lift
74
Breathing
Start rescue breathing if patient has a palpable pulse of >60, and theres inadequate breathing of <10 breaths/min, and continue until spontaneous breathing returns
Is HR is at <60 then do compressions in addition of rescue breaths
Reassess every 2 minutes
75
Breathing: Rescue breathing: lone provider
30:2
| Just breathing: rate of 12-20 breaths/min (1 breath every 3-5 seconds)
76
Breathing: Rescue breathing: 2 rescuers
15:2
| Just breathing: rate of 10-12 breaths/min (1 breath every 3-10 seconds)
77
If patient isn't able to maintain airway
Place an artificial airway
78
ET tube
Preferred because it allows greatest control of airway
Directly inserted into trachea all the way done to the carina of the bronchi
Can suction fluids and secretions through them
Can prevent aspirations
79
LMA
Inserted directly into pharynx, and does not go as far down as ET tube
Mostly used when patient is trapped in a sitting position
Also when there's suspected trauma to cervical spine or head tilt chin lift isn't possible
Also when intubation with an ET tube is unsuccessful
Easier to insert causing less pain than ET tube
Cannot suction
Do not prevent aspiration
80
Physician needs for intubation (blades)
L-shaped blade -Miller
Curved blade -MaCintosh
RN responsibility to ask the provider what size ET they want, or RN see what size they needed based on: swelling, age, weight,.
Also give stylet to be place in ET tube before insertion
Also ask what size blade and endoscope they want
81
Artificial airway established
Once placed, continue compressions and no longer need to cycle to ventilate
Rescue breaths are provided 1 breath every 6-8 seconds (about 8-10 breaths/min)
ABGs are drawn (how we know what to set the ventilator to)
Excessive ventilation should be avoided
NGT placed to decompress the stomach, preventing aspitations, and get air out of tummy
Document size, depth of ET tube and that it is secured
82
IV sites
Scalp
Heel
Antecubital
Last resort: IO (after 2 unsuccessful attempts)
83
Causes of difficulty getting IV in children
Shock, hypothermia, vasoconstriction
84
IO placement
Only in emergency situations when IV access is not available or feasible
Can be done on any age except preterm neonates
Placed in the proximal medial aspect of the tibia
Ultimately central circulation
Marrow functions as a non-collapsible venous access route, whereas peripheral veins do collapse due to vasoconstriction
Need to push hard to get fluids in
85
IO complications
```
Extraversion of fluids when needle is misplaced
Compartment syndrome
Infection
Pain
Fracture
```
86
Most commonly used IVF pedi
```
0.9%: Normal saline (20mL/kg bolus)
Lactated ringers: LR
5% dextrose in water: D5W
5% dextrose and 0.9% NS: D5NS
5% dextrose and 0.45% NS: D5 half NS
Any K added to their IVF will be indicated in RED!!
```
87
IVF rate
100mL for first 10kg
50mL for next 10kg
20mL for any remaining kg
88
Drug therapy: Cardiac arrest
Next to last line of treatment
Majority of pediatric resuscitations will not require a lot of drugs
Pediatric drug doses are based on weight
Some medications in the crash cart will tell you the dosages
89
IV medications administration
ALWAYS look at the concentration
Triple check calculations
When pulling up medication: show to another person and say what and how much, then pass it to whos delivering it, they will say what and how much given now. The person documenting will document what and how much given at ___ time.
90
Code drugs
```
Epinephrine
Atropine
Amiodarone & Lidocaine
Dextrose
Sodium bicarbonate
Naloxone
Adenosine
Dopamine
Dobutamine
```
91
Code drugs that can be given through ET tube

Epinephrine
Atropine
Naloxone
```
92
Epinephrine
Increased HR, contractility, and BP
93
Atropine
Increased HR
94
Amiodarone & Lidocaine
Converts V.fib, pulseless Vtach or Vtach with pulse
| Some atrial tachyarrhythmias
95
Dextrose
Reverse hypoglycemia
96
Sodium bicarbonate
Reverse metabolic acidosis
97
Naloxone
Reverse opiate narcotic depression
98
Adenosine
Converts paroxysmal SVT, push hard and fast, momentarily stops the heart
99
Dopamine
Improves BP
100
Dobutamine
Increases contractility of heart
101
Blow by O2
Keep their head midline
| May be either a narrow O2 catheter with small perforations through with O2 can flow or corrugated tubing
102
Blow by used when
The child will not tolerate other means of O2 therapy, Low O2 concentrations with humidification are needed, if they are vomiting, or have facial injuries
Concentration of O2 delivery varies according to the flow rate and proximity to the face
Can be used for young infants
103
Nasal cannula
Low flow
High flow
Can be use to deliver low concentrations of O2
Flow rate set higher than 6L will irritate the nasopharynx without improving the child's oxygenations
Correct placement of nasal prongs
104
NC Liters/ Min percentages
```
1L/min: 24%
2L/min: 28%
3L/min: 32%
4L/min: 36%
5L/min: 40%
6L/min: 44%
```
105
O2 Facemask
Agitated and refused facemask: mom can hold baby and facemask near face
Bag has to be full
Size of the mask is important when administering O2
-Mask should extend from the bridge of the nose to the cleft of the chin
-Should fit snugly on the face but put not pressure on the eyes to avoid stimulating the vagal response
106
Types of facemask
Simple face mask
| Non rebreather
107
Simple face mask
30-60% O2 with a flow rate of 6-10L/min when a tight seal is maintained on face
108
Non-rebreather
60-90% O2 with a flow rate of 12-15L/min when a tight seal is maintained on face
109
Common dysrhythmias
Bradycardia
Asystole
Pulseless electrical activity (PEA)
110
Asystole
Do not administer shock because there is no electrical activity, continue CPR until something else is figured out
111
PEA: Characterized
Unresponsiveness and the lack of a palpable pulse in the presence of an organized cardiac electrical activity
Some situations that cause sudden changes in preload, afterload, or contractility often cause this.
112
PEA: Most common cause
Hypovolemia
113
PEA: Treatment
Rapid fluid bolus of 20ml/kg of NS IV
114
Treatment of PEA and Asystole
Determine reversible causes (PAT2H4)
115
PAT2H4
P: pneumothorax
A: acidosis
T2: toxic ingestion, tamponade
H4: hypovolemia, hypoxia, hypo/hyperK, hypothermia
116
Vfib/Vtach
Not common in children
| May be seen in adolescents with OD
117
Vfib
Abnormal heart rhythm and is seen in sudden cardiac arrest
Chaotic and unorganized
Heart quivers and cannot effectively pump blood
Short lived and will deteriorate to asystole if not treated properly and promptly
118
Vfib cause
By an abnormal and very fast electrical activity in heart
119
Vfib Treatment
Only effective treatment is electrical shock called defibrillation ( an electrical current applied to the chest)
120
Vfib Defibrillation goal
Electrical current pass through the heart stopping the Vfib and giving an opportunity for heats normal electrical system to take over
The defibrillation helps the heart reorganize and start pumping blood effectively again
121
AED
Comes in various sizes
| They give you verbal instructions of how to apply pads, and will set amount of Joules according to the patient's rhythm
122
Defibrillator
Manual and you'll adjust this according to Broslowe tape of instructions or your code sheet
123
AED/Defibrillator pads
Different size for 1-8yrs
Adult pads
If there isn't Pedi pads then you can use adult pads but make sure they dont touch. Place one in the center of the child's chest and the other on the center of the child's back
124
AED/Defibrillation: Reminders
Make sure chest hair is out of the way
Make sure there is no pacemaker (place pad at least 1in from the device)
Look for medicinal patches, don't place pad on the patch
Clear before activating it
Dont use in water!! Dry the patient off before shocking, remove the patient from any water before shocking
125
Bradycardia Treatment
Oxygenation/ventilation
| F/u with Epinephrine, atropine and transcutaneous pacing
126
V tach (hemodynamically stable) Treatment
Amiodarone or lidocaine or Procainamide
127
Unstable Tachyarrhythmia Treatment
Immediately synchronized cardioversion for PSVT
| IV access available give adenosine before cardioversion
128
Vfib or pulseless Vtach Treatment
Immediate defibrillation, epinephrine, intubation
| Consider amiodarone, lidocaine, magnesium sulfate
129
Asystole and PEA Treatment
```
We want to establish some type of rhythm/electrical activity
Cant use AED
Not shockable
Continue CPR
Intubation
Epinephrine
Determine cause - reverse it
```
130
Nurses role in resuscitation
Patient assessment
Start CPR
Breathing really fast or stop breathing: start CPR
Witnessed it? Not witnessed?
131
CPR: Team leader
Oversees the entire process, monitors effectiveness, orders drugs, treatments, labs,
Doctor is the one that runs the code not the nurse
132
CPR: Team member
Each has a specific job: compressions, BMV, starting IV, drawing labs, labeling and giving meds, "go-fer": labs, equipment, recorder, charting, keeping family members informed
Any time an order is given, it must be repeated back to physician for confirmation and so that every team member hears
There has to be someone whose role is to just document on the ode sheet
133
CPR: Nursing intervention: Family support
During arrest: support is aimed at keeping family informed of child's status, assuring them that all is being done
Must consider needs, fears and concerns of family members
Family should be able to be present during code
