Peds Oxygenation Flashcards
Hypoxemia
low oxygen content in the blood
Hypoxia
low oxygen supply in the tissues
How do newborns breathe for the first 4 weeks
through their nose
How much mucus do newborns/infants produce and why does it create an infection risk
very little, mucus is a cleaning agent
When do sinuses develop
6-8 years old
Size of pediatric nasal passages
very small (easily obstructed)
Risk for obstruction throat anatomy
large tongues, tonsils, and adenoids
What is the first sign of a respiratory illness
increased respirations
What does cyanosis occur from
hypoxemia
What does pallor result from
peripheral vasoconstriction
What are beta adrenergic agonists used for
short acting inhalation for asthma, CF, bronchiolitis, bronchospasm
How does beta adrenergic agonists work
bind to receptors in the lungs to cause relaxation
Side effects of beta adrenergic agonists
nervousness, jitteriness, tachycardia
What is racemic epinephrine used for
bronchodilation (croup, emergent drug)
When do we monitor for rebound bronchospasm
with the use of racemic epinephrine
When is racemic epinephrine contraindicated
cases of epiglottitis
When are antivirals used
RSV patients on ventilators
What should be provided during oxygen delivery
humidification
What oxygen delivery system is not good for mouth breathers
nasal canula
Nasal canula
1-4 L/min
What oxygen delivery system mixes room air with O2 and is most often used with COPD
venturi mask
What oxygen delivery system is used most often for severly hypoxic patients
nonrebreather mask
What oxygen delivery system is used for infants with humidification
oxygen hood
What is the flow of high flow nasal canula dependent on
patient weight, titrated based on work of breathing and respirations
