Oxygenation Flashcards
what are some risk factors r/t the upper airway
6
smaller airway position of trachea tonsils and adenoids larger epiglottis higher in the neck larger tongue cartilages easily collapse
what are some risk factors r/t the lower airway
4
few alveoli
abdominal breathers
ribs horizontal
higher metabolic rate - > O2 need
what are the 3 most common causes of oxygenation disorders
infection
congenital disorders
FB obstruction
what are 2 examples of congenital disorders
asthma
CF
when does the number of alveoli reach it’s max
8 years
when do the tonsils and adenoids reach actual size
12 years
where should you listen for lung sounds
side & back
what is a very serious sign when assessing a pt with an oxygenation problem
head bobbing
which 2 types of retractions come first
substernal
subcostal
which 2 types of retractions come last
intercostal
supracostal
what is an increased work of breathing
respiratory distress
what is a clinical condition in which there is inadequate blood oxygenation and/or ventilation to meet the metabolic demands of tissues
respiratory failure
what is the absence of breathing
respiratory arrest
what are 6 indications of respiratory distress
restlessness nasal flaring circumoral cyanosis expiratory grunting retractions tachypnea
what is the earliest sign of hypoxia
restlessness
what occurs prior to respiratory arrest
bradycardia
what are 5 s/s of severe respiratory distress
grunting severe retractions diminished breath sounds hypotonia decreased O2 sats
what are 6 s/s of respiratory arrest
mottling unresponsive absent chest wall movement absent respirations weak/absent pulses bradycardia limp
for which disease is a sweat chloride test done
CF
what does a cxr show
location of illness
what does an mri/ct show
FB
obstruction
why are cultures not immediately done
can cause further irritation
what are 5 ways to manage oxygenation problems
oxygen humidity suctioning chest PT meds
what position should the pt be in
fowlers/semi-fowlers
