Insertion into foot or femoral vein may keep patient from ambulating
Make IV pumps mobile
Observe integrity of insertion side (look for infection, phlebitis)
11
Q
What is infiltration?
A
Medication enters the interstitial spaces instead of the veins, which damages the surrounding tissues.

IVC --> R atrium --> Foramen ovale --> L atrium --> L ventricle --> Ascending aorta
35
What fetal circulation supplies the lower body?
SVC --> R atrium --> R ventricle --> Pulmonary artery --> Ductus arteriosus --> Descending aorta
36
What are the 2 main points of shunting in embryonic heart?
Foramen ovale
| Ductus arteriosus
37
What is the foramen ovale?
Opening between the atria which allows for right to left-blood flow bypassing the lungs
38
What closes the foramen ovale?
Before 1st breath, lungs are high pressure
At first breath, lungs expand with air; this decreases pulmonary vascular resistance and increases systemic resistance
Blood returns to the left atrium making pressure higher on the left than the right which causes the foramen ovale to gradually seal shut (within 3 months)
39
What is the ductus arteriosus?
Connection between the pulmonary artery and descending aorta
40
What closes the ductus arteriosus
After the 1st breath, lungs become filled with O2 which causes blood O2 to rise
The wall of the ductus arteriosus contracts and closes between 10-15 hours after birth. Anatomical closure by 2-3 weeks
41
Where do you look for cyanosis?
Nail beds and lips
42
What is an atrial septal defect?
Hole in septum between the atria (persistent foramen ovale).
Oxygenated blood flows from L to R atria. Can put stress on heart and lead to CHF.
43
What is a ventricular septal defect?
Opening in septum between L and R ventricle.
Blood flows from L --> R. Heart works harder to pump blood to body
44
What is a patent ductus arteriosus?
DA doesn't close.
Oxygen-rich blood from aorta mixes with deoxygenated blood from pulmonary artery. Blood shunts from aorta to right ventricle.
45
What is coarctation of the aorta?
Narrowing of the aorta just after it branches off to the upper body. Blood flow is obstructed to the lower body.
46
What is pulmonary stenosis?
Fused, thickened, or missing leaflets of pulmonary valve
47
What is aortic stenosis?
Fused, thickened, or missing leaflets of aortic valve
48
What is tetrology of fallot?
Combination of heart defects
- Ventricular septal defect
- Aortic override
- Right ventricular outflow obstruction
- Right ventricular hypertrophy
Accounts for 50% of cyanotic defects
49
What is transposition of the great arteries
Aorta comes out of right ventricle, pulmonary artery out of left ventricle
50
What is a balloon atrial septostomy used for?
When transposition of the great arteries requires urgent intervention. Creates an ASD to solve the problem temporarily
51
What is a complete A-V canal defect?
Hole in center of heart where atria and ventricles meet - develop with one large valve
52
What is pulmonary atresia?
Abnormally formed pulmonary valve, often associated with VSD
53
What is tricuspid atresia?
Also Hypoplastic R Heart Syndrome
Tricuspid valve fails to develop. Smaller than normal R ventricle.
ALWAYS have ASD, sometimes VSD
54
What is hypoplastic L heart syndrome?
Underdeveloped or absent L ventricle
Mitral valve stenosis/atresia or aortic stenosis/atresia.
Aorta is underdeveloped and narrowed
55

58
What is the chest wall like in infants?
1/3 of trunk

Narrow intercostal space (ms not at good length-tension relationship; belly breathing)
Minimal sternal stability
Limited ability to expand in all 3 planes
Diaphragmatic nose breather
59
Why is there "reaching" in infant (3-6 mos)
UE muscle groups develop
Getting out of physiologic flexion
60
Why does baby hold head upright and push up in prone (3-6 mos)?
Increased anterior chest and extensor musculature
Getting out of physiologic flexion
61
When are infants able to fully expand their lungs/chest wall?
When they start to sit (around 6 mos). Before then, often laying against a surface
62
Independent sitting at 6-12 months causes what developments?
Trunk tone balances between flexion/ext
Head moves independent of trunk
Developing abdominal muscles pull and rotate ribs downward
Elongation of chest wall
63
What happens when the chest wall elongates at 6-12 months?
Diapragm becomes more dome shaped
Abs increase in strength - secretion clearance, diaphragm/visceral support
Intercostal muscles widen as ribs rotate down - stabilize chest wall, increase 3D dimension during inhalation
64

88
How does positive expiratory pressure (PEP) work?

93
When do you start teaching autogenic drainage?
Around 10 years old
94
Exercise capacity was an independent predictor of...
life expectancy in CF patients
95
What is the relationship between exercise and secretion mobilization?
Exercise forces us to do the huffing maneuver
96
Sternal precautions (pediatrics)
2 weeks: no prone
For 6 weeks: no bilateral UE over head, no pull to sit, no lift from under arms, no forward bend, no lifting > 10 lbs, no driving
97
Relationship between exercise and CF patients?
Sodium conductance in respiratory epithelium is partially blocked during moderate intensity which increases water content of mucus and enhances airway clearance.
98
Why is postural re-education important in cardiopulmonary PT?
All trunk muscles are both respiratory and postural muscles
99
Why should you do scar massage on pediatric patients who had surgery in the trunk?
Scars can limit mobility as the child grows (decrease trunk expansion)
100
Indications for mechanical ventilation

Respiratory failure
Allow for sedation
Improve/maintain ventilation and respiration
101
Ventilator considerations
```
Route
Mode
Pressure support
Rate
Tidal volumes
Positive end-expiratory pressure
FiO2
```
102
Things to remember about patients on a mechanical ventilator
Don't pull it out
Don't move it
Patient will be uncomfortable and will cough if they move; let them adjust to new positions
Not a contraindication for mobilization though might change how you go about it (ex: don't do a sit-pivot transfer)
103
Types of ventilator routes
Endotracheal tube (ETT)
Tracheostomy / Trach collar
Ventilator circuit
104
How far down does a ventilator tube go?
Down to the carina
105
Damage that can be caused by an ETT?
Damage to throat structures
If pushed in too far, can go into the R lung
106
What is a water trap for on a ventilator circuit?
For condensation buildup - needs to be lower than patient so they do not aspirate
107
What is the balloon/cuff for on an ETT/trach?
Holds the tube in place and creates a seal to make sure air gets into the lungs
108
If a patient can speak while on a trach, you should suspect...
a cuff leak
109
If a patient is on a trach and can speak, but there is no cuff leak, what could that mean?
Trach without a cuff is being used to wean the patient off the ventilator (look for lack of inflation tube)
Fenestrated trach (hole in proximal tube) allows for talking even with a cuff inflated
Cuff just isn't able to create a seal
110
PT considerations with Route
Don't pull it out
Comfort
Inspect airway and note position
Cuff (is patient able to talk?)
111
Why do you wean a patient off of a ventilator? PT consideration?
To prevent respiratory muscle atrophy.
Weaning requires more energy toward respiration. Activity after this can fatigue them too much.
112
If a patient has a trach and wants to talk, what can you do?
Deflate the cuff and cover trach hole
113
ETT vs. trach
ETT - short-term, no surgery
Trach - long-term, aid in weaning, decreased resistance, improves mobility, comfort, speech/eating, pulmonary hygiene, reduced laryngeal injury
114
Types of breath provided by ventilators?
Mandatory breath
Assisted breath
Spontaneous breath
115
Modes on the ventilator?
Assist control (AC)
Intermittent Mandatory Ventilation (IMV/SIMV)
Pressure Support Ventilation (PSV)
Continuous Positive Airway Pressure (CPAP)
116
If patient moves from more to less support during the day, that means...
they are improving (though their exercise might be just the work of breathing)
117
What is SIMV?
Same thing as AC but lets patient take over if he initiates the breath. Must overcome resistance of trach, though.
118
What is CPAP?
Keeps a little extra pressure in the airways to keep them from collapsing which allows for more time for oxygenation
119
Low pressure alarms
Patient disconnection
Circuit leaks
Airway leaks
120
High pressure alarms
```
Patient coughing
Secretions or mucus
Patient biting tube
Reduced lung compliance
Increased airway resistance
Patient fighting ventilator
```
