Clinical signs of
hypoxia?
tachycardia, tachypnea, grunting,
nasal flaring,
decreased rectal temperature,
bradycardia,
apnea and cyanosis
Methods to reduce incidence of ROP and BPD?
constant monitoring of FiO2, SaO2 and PtCO2, control teperature and humidity, administer Vitamin E prophylactically and maintain PaO2 in the acceptable range of 50-80mmHg
Methods to maintain the infant's NTE?
increase warmth, keep infant dry (evaporation), place in warm environment ( conduction), do not place by cool air currents (convection) and do not place on cool surface (radiation).
How is TcO2 monitoring used?
in the hyperbaric chamber for wound treatment, monitors perfusion.
Warming the TcO2 site causes?
vasodilation, increases temperature which leads to a shift to the right which equals less affinity and changes in lipid structure of the skin which allows for greater diffusion
Why is TcO2 less than PaO2?
O2 is extracted in the tissues
Why is TcCO2 greater than PaCO2?
CO2 is picked up in the tissues
Describe the required two-point calibration for transcutaneous monitoring?
PtO2 requires a zero solution of sodium sulfate and PtCO2 requires a 5% and 10% CO2 mixture
What type of electrode is TcO2 monitored by?
Modified clark electrode
What type of electrode is TcCO2 monitored by?
Severinghause electrode
Amount of power required to maintain temperature at site is __________ related to perfusion.
directly
This quadrant of the chest is best for monitoring preductal arteriosis oxygenation?
Upper right quadrant
This can be effected by a change in an infant's position?
perfusion
If preductal PO2 is greater than postductal PO2 what does this indicate?
a right to left shunt
What is the most common site to place an arterial catheter in the neonate?
umbilicus
If the neonates HR is less than 100 what should you begin?
assissting ventilation with BVM
If the neonates HR is less than 60 what should you begin?
chest compressions
Describe two chest compression techniques for the neonate?
two handed with thumbs compressing the sternum or two fingers if infant is large or rescuer hands are too small
The compression rate for an infant should be?
90
How many events should occur per minute when performing neonate resuscitation?
120
What does APGAR stand for?
Appearance of skin color, Pulse, Grimace or reflex irritability, Activity or muscle tone and Respiratory effort
Name four drugs used for therapy during neonal resuscitation?
epinepherine, bicarb, dextrose and narcan
Recommended ET tube size for an infant less than 1000g?
2.5
Recommended ET tube size for an infant between 1000g-2000g?
3
Recommended ET tube size for an infant between 2000g-3000g?
3.5
Recommended ET tube size for an infant greater than 3000g-4000?
3.5-4.0
How is CPAP administered?
head chamber, nasal prongs, nasopharyngeal tube and ET tube
