Pals 3 Questions And Answers WithVerified Solutions 100% Correct!!!
does resp or cardiac arrest have better neuro outcomes - ANSWER✔✔ resp
o2 consumption in kids v adults - ANSWER✔✔ kids 6-8ml/kg compared to 3-4
ml/kg in adults
what is hypoxemia - ANSWER✔✔ decreased arterial oxygen sat detected by pulse
ox or direct measuremnt of o2 sat in an abg
so you want their oxygen level at least - ANSWER✔✔ 94
hypoxia v hypoxemia - ANSWER✔✔ hypoxemia is low blood o2 sat, hypoxia is
pathologic odnition in which body as a whole or region of body is deprived of
adequate oxygen
you can be hypoxic without hypoxemia
you can have hypoxemia without hypoxia
example of hypoxemia without hypoxia - ANSWER✔✔ cyanotic heart disease
leading to decreased overall sats but compensated for by increased CO and
polycythemia
example of hypoxia without hypoxemia - ANSWER✔✔ anemia
,early v late signs of hypoxia - ANSWER✔✔ tachypnea to bradypnea with
inadequate effort
increased effort like flaring and retractions leading to head bobbying and seesaw
respirations, grunting
tachy leading to brady
both have pallor, mottling, cyanosis can be early or late
agitation/anxiety/irritable leading to decreased level of consiocuness
o2 content formula - ANSWER✔✔ 1.36*Hgb concentration x SaO2 + .003xPaO2
causes of hypoxemia - ANSWER✔✔ low atmospheric po2----altitude
alveolar hypoventilation
diffusion defect
v/q imbalance
right to left shunt
why can you get hypoxemic from altitude - ANSWER✔✔ decreased barometric
pressured leading to decreased paO2
alveolar hypoventilation examples and mechanism - ANSWER✔✔ cns infection,
tbi
overdose
, neuromuscular
apnea
hypercarbia---dsipalces alveolar o2 resultion in decreased o2 tension and
hypoxemia
diffusion defect examples and path - ANSWER✔✔ pulmonary edema
instertital pneumonia
alveolar proteinosis
impaired movement of o2 and co2 leading to hypoxemia and if severe increased pa
co2
diffusion defect treatment - ANSWER✔✔ positive pressure ventilation
v/q imbalance exsamples and path - ANSWER✔✔ pneumonia
atelectasis
ards
asthma
bronchiolitis
foreign body
mismatch of ventialtion and perfusion, blod lfow through areas of lung that are
inadequatley ventilated resulting in incomplete oxygenation of blood------
decreased o2 sat and PaO2 and lesss increased pa co2
