Percussion and Palpation of the Chest
·
Palpation
o
Procedure
o
Place hands lightly on the patient’s chest with fingertips and palms in
contact with the chest.
o
Have the patient take a slow, deep breaths if possible
o
Used to determine
§
Asymmetrical chest movement
§

o
Procedure
o
Placing one or more fingers of one hand between the ribs of the
child and then tapping the tips of those fingers with a finger from the
other hand
o
The sound make is assessed with each area of one lung as compared to the
other.
o
Useful in determining the presence of

Advantages |
Disadvantages |
|
Nasal Cannula |
.01 – 4 LPM |
Variable |
Good for long term care in chronic
disease states, tolerated fairly well, easy to apply and
lightweight |
Active infants may not tolerate
Inaccurate Fi02
Insufficient humidity |
|
Masks
Simple Masks
PRB
NRB
|
Minimum
6 LPM |
Variable |
Higher concentrations of FiO2
over cannula, also good for transport |
C02 can buildup
When there is insufficient
flowrates are used;
Most infants and
Children don’t tolerate very well
and may cause necrosis |
|
Head Hood |
Minimum
7 LPM |
21% - 100% |
Stable Fi02 that does not
interrupt daily care; warm and humidified gas at any Fi02 when
it used with a blender |
If the flow is too high there can
be hearing damage and cause a layering of the Fi02 ; Overheating
can result in apnea;
Underheating can cause increased
02 consumption; Inadequate flow will result in a build-up of
C02 |
|
Mist Tents |
Minimum
10 LPM |
21% - 50% |
A cool aerosol |
Varying in the Fi02 ; fog or mist
with higher
02 output.; Asphyxiation if the tent collapses |
|
Isolette |
|
21% - 70% |
Warmed humidified gas, with a
stable Fi02 when used with a head hood. |
Varying Fi02 without the hood ;
Good for long stabilization; Risk of bacterial contamination

o
The mobilization of bronchial secretions
o
The prevention of secretion accumulation

Improvement of gas exchange in the treatment of acute and chronic lung
disease

Mechanical Ventilation
·
Overview
o
Pediatric patient’s are too often treated as small adults or large
neonate’s
·
Indications
o
Same as any age group
§
Acute respiratory acidosis
§
Impending respiratory failure
§
Apnea
§
Neuromuscular
§

Methods of Ventilation
o
Selected according to the patient’s size and weight
o
Special needs for patients
o
Volume vs. Pressure ventilator
·
Volume
o
Consistent Vt - increase risk of barotrauma
o

·
Pressure
o
Barotrauma is reduced - volumes vary as the lung compliance changes

Parameters
o
Ventilator rate
§
Used in combination with Vt for adequate alveolar ventilation
o
Fi02
§
To maintain a saturation of 92% - 95%
§
Use an analyzer with limits
§
Effects should be to wean the FiO2 below 60% to prevent oxygen toxicity
o
PEEP
§
Titration study
§
The PEEP is increased in small amounts every 10 – 15 minutes

Ethics
·
The study of rational processes for determining the most morally
desirable courses of action with conflicting moral choices
·
Fundamental Ethical Principles
o
Autonomy
§
The patient has the right to make decisions regarding their medical care
§
Two basic requirements
·
The right to decide
·
Act without coercion
§
Paternalism
o
Beneficence
§
All medical decisions must be made so as to do good for the patient.
§
Challenges
·
When the patient, the family, and care givers cannot agree on a course
of action.
§
Medical treatment is not mandated if
·
It is not medically indicated
·
Merely prolongs the process of dying
·
It’s futile and inhuman
