toddler age group- 2 years and older
Changing the PE approach based on age: 0-6 months
proceed with traditional HtT exam
Changing the PE approach based on age >6 months when there is stranger and separation anxiety (5 tips)
- DON’T begin by examining the head/ears/nose/throat
- DON’T examine the child on the examining table
- Examine the child while in the parent’s lap
- BEGIN the exam with the least anxiety-provoking area, usually start with the chest and abdomen
- Do the head and neck exam LAST, end the exam with the ears followed by the throat
Should you immediately place the stethoscope on the child?
no, have the child first hold the auscultation end of the stethoscope to become familiar and have a penlight, small toy, etc that they can be distracted with
Are your parents useful in the exam?
Yes, they’re your ally
On the newborn and infant exam, how should you proceed?
start with what the baby gives you
if the baby is quiet, start with the heart and lung exam
What percent of children have an innocent heart murmur on physical exam?
50%
what are you inspecting for on the CV exam?
- skin color
- pallor, cyanosis, plethora (polycythemia)?
- chest wall movement.. heaves, symmetry
How do you assess vasculature on the CV exam?
- check cap refill
- palpate brachial and femoral pulses

coarctation of the aorta
or
aortic stenosis
LIFE THREATENING, no blood getting to the body

1-2 weeks
what is plethora/polycythemia?
too many RBCs causes a ruddy (reddish purple) complexion
4 places to auscultate on CV exam
RUSB
LUSB
LLSB
apex
In newborns, you also auscultate on the back for ____
peripheral pulmonary branch stenosis
What is peripheral pulmonary branch stenosis?
stenosis where the pulmonary artery bifurcates
what does peripheral pulmonary branch stenosis sound like on auscultation?
high-pitched whoosh… sounds will echo equally to both lung fields
What can you do if the child is crying on CV exam? (we need a quiet room)
give them something to suck on
take your time
name 2 challenges on the CV exam
- lung sounds often sound like heart sounds
- rate: infants have a baseline rate in the 100s
What’s special about the patient’s position in a pediatric CV exam?
MUST examine in both supine and and upright
Why examine peds supine and upright on CV exam???
Normal heart sounds when sitting up, but systolic murmur when lying down is normal.
What do you expect to hear differently between sitting up and laying down on CV auscultation?
As blood comes back to the hear, the venous return is impacting the murmur..
Sitting up: VR is reduced, murmur is decreased
Laying down: VR is increased, murmur is pronounced
What would you hear if there is Hypertrophic Obstructive Cardiomyopathy (HOCM)?
Opposite of a normal heart murmur..
Sitting up: murmur increased
Laying down: murmur decreased
What are you observing for on the Lung/Thorax exam?

- paradoxical movement between chest and abdomen, “see saw” respirations
What are “see saw” respirations?
Normally, when we breathe in, the chest AND abdomen expand. With these, the chest expands, the abdomen sucks in.
This is due to diaphragmatic fatigue and use of the abdominals to compensate
What should you think about if you see “see saw” respirations?
the patient is on the verge of respiratory failure and need of intubation!
2 tips for auscultating the lungs
- coughing or crying is an excellent opportunity to listen to the lungs
