Cardiac Flashcards
small hole located in the septum, which is the wall between the two upper chambers of the heart (atria) that takes most blood to left atrium to bypass lungs and does most of upper body
foramen ovale
is a blood vessel connecting the main pulmonary artery to the proximal descending aorta. It allows most of the blood from the right ventricle to bypass the fetus’s fluid-filled non-functioning lungs and go straight to supply lower body and placenta
ductus arteriosus
what closes when cord is clamped
foramen ovale
what constricts and closes within 10-15 hrs of birth
ductus arteriosus
pressure is higher on which side in unborn baby’s heart
right
newborn HR
120-160
HR at 1 month-1 year
80-140
newborn systolic BP
50-70
newborn RR
30-50
one month old systolic
70-100
one month RR
20-30
when is newborn acrocyanosis not ok
usually after the 1st day but def 2-3 days
assessment of newborn
respirations, pulse, BP, color, chest, hear auscultation, fluid status, activity and behavior, general
why do you do an exam at 24 hours
wait till after heart structures are closed (pre ductal and post ductal stages)
A FULL TERM HEALTH INFANT SHOULD HAVE O2 SAT OF
95-100
pre term infant has O2 sat of?
84-90 but always see what it should be based on facility by the minute
polycythemia
thickened blood (clot risk) due to increased blood viscosity. keep baby hydrated
long term hypoxia
clubbing of nails
TET spells
cold legs and feet/blue spells. dangerous
pulse and BP in ams and legs are different
cardiac defect
what can happen to older kids with heart issues
headache from increased BP in the head
diagnostic procedures
Chest xray, echo-cardiogram, MRI/CT, Cardiac catherization
can measure the heart size, shape, pulmonary markings, and cardiomegaly
chest xray
visualize anatomic structures
echo-cardiogram
diagnose and or treat cardiac defects
cardia catherization
newborn male hemoglobin and hematocrit levels
Hbg - 14.7-18.6 g/dL. Hct - 43.4-56.1 %
newborn female hemoglobin and hematocrit levels
Hbg - 12.7-18.3 g/dL. Hct - 37.4-55-9 %
don’t restrict what in cardiac kids
fluids
increase formula from what to what
20 calories/oz to 30 calories/oz
education for parents and caregivers
humidified oxygen, loose-fitting clothes, positioning techniques
o2 carrying protein of RBC
hemoglobin
percentage of blood made up of packed RBC
hematocrit
