peds respiratory Flashcards
Upper respiratory tract
Oronasopharynx, pharynx, larynx, and trachea
Lower respiratory tract
Bronchi, bronchioles, and alveoli
Diameter
The diameter of the trachea is roughly the size of the child’s pinky finger
Distance
The structures are shorter
Allows organisms to rapidly move down
Allows fluid to build-up
Age - younger than 3 months
Immunity increases with age
Infants younger than 3 months Still have maternal antibodies
mycoplasmal more common
(my fall and winter)
in fall and winter
RSV - when does it occur?
(S is for spring)
spring and winter
Generalized signs and symptoms and local manifestations different in young children - think about the lecture
Fever
Anorexia
R/T vomiting, diarrhea, abdominal pain
Cough, sore throat, nasal blockage or discharge
Respiratory sounds
obligate nose breathers until when?
until about 4 weeks can’t coordinate mouth breathing
Infants are abdominal breathers- Diaphragm movement creates what type of pressure?
Ribs are primarily cartilage
Very flexible
Inefficient ventilating
Diaphragm movement during inspiration creates negative pressure allowing lungs to expand
Assessment with Auscultation
Adventitious breath sounds
Stridor
Wheezes
Rhonchi
Crackles
Diminished breath sounds
What if you heard wheezes in a child, then an hour later the wheezes were “quieter” or “softer”?

Oxygen Mask - how much O2? and can they eat with it?
Variety of sizes to fit
Deliver up to 100% FIO2
Young children afraid to wear mask
Can’t eat or drink while wearing mask
“Blow–by” Oxygen - when to use?
Humidified Oxygen/Air
No way to measure FIO2 child receives
Use if child won’t tolerate any other modality
Oxygen Hood - what percentage of O2?
FiO2 up to 100%
High humidity
Easy access to body
Oxygen Tent (“Croupette Tent”) - how high is the FIO2?
(tenting at 40)
High humid environment
FIO2 only up to 40%
Separation Anxiety
Aerosol Therapy
Metered-dose inhalers
Use a spacer
Nebulizers
Used to administer meds such as bronchodilators
Vaporizers
Increases humidity in room
FLUIDS
Children with respiratory conditions get dehydrated easily
Fluids thin the sputum/mucous
Encourage PO fluids
Popsicles, jello, juice, electrolyte drinks, breast feeding, water
IV fluids
Humidified O2
MEDICATIONS
Bronchodilators
Ipatropium Bromide, Albuterol Sulfate, Epinephrine
Decongestants
Nose Drops (NS), Expectorants
Antipyretics
Acetaminophen, Ibuprofen
Antibiotics
For know bacterial infections
Prophylactic secondary bacterial infections
PULMONARY TOILET - 2 things
postural drainage and incentive spirometers
ease respiratory effort
Increase humidity, maintain cool environment
Elevate HOB
Promote nasal and pulmonary drainage
Clean nares with bulb syringe
Suction oronasal pharynx
Perform postural drainage and chest physiotherapy
administer o2
care of epiglottis - avoid using what?
Avoid using tongue blade
Keep tracheotomy set at bedside
Provide tracheostomy care
Infectious Agents
Viruses
RSV
Para-influenza
Others
Group A β-hemolytic streptococci
Staphylococci
Chlamydia trachomatis, Mycoplasma, pneumococci
Haemophilus influenzae
OM and Infant Feeding Methods - which immunoglobulin?
Breast-fed infants have less OM than bottle-fed infants
Immunoglobulin A
Position in breast-feeding may decrease reflex in eustachian tubes
Acute Otitis Media (AOM) - caused by which organisms? 2 of them
(ears are hemophaliacs w/ strep)
Bacterial Infection in middle ear:
Haemophilus influenza and Streptococcus pneumoniae
Diagnosis of AOM
Otoscopy (handheld to look in ear)
Tympanic membrane (measures pressure in ear, not done very often)
Bright red, bulging, may be dull with no visible landmarks or light reflection, diminished mobility
C&S of drainage indicates organism
AOM Treament
