ASPHYXIA – THE BASIC
1.Primary Apnea: When asphyxiated,
the infant responds with a increased RR.
If the episode continues, the infant
becomes apnic, followed by a drop in HR
and a slight increase in BP.The infant will
respond to stimulation and therapy with
spontaneous respirations.
2. Secondary apnea: after primary
apnea, the infant responds with a period
a gasping respirations, falling HR, and
falling BP.The infant takes a last breath
and then enters the secondary apnea
period.The infant will not respond to
stimulation and death will occur unless
resuscitation begins immediately.
* Because after delivery of an infant it is impossible to
differentiate between primary apnea and secondary
apnea, assume the infant is in secondary apnea and begin
resuscitation immediately.

Equipment
Equipment and medications should be checked
as a daily routine and then prior to
anticipated need. Used items should be
replenished as soon as possible after a
resuscitation.
The delivery room should be kept relatively
warm and the radiant heater should be
preheated when possible. Prewarming of
towels and blankets can also be helpful in
preventing excessive heat loss from the
neonate.

ANTICIPATION
ASSESSMENT OF ACTION
1.PREVENT HEAT LOSS
Place the infant under an overhead
radiant heater to minimize radiant and
convective heat loss.
Dry the body and head to remove
amniotic fluid and prevent evaporative
heat loss. This will also provide gentle
stimulation to initiate or help maintain
breathing.
