Whats the most common O2 administration device used for a neonate and what starting
FiO2 (if not previously on O2) - correct Answer-Oxygen Hood 30-45%
What is the flow rate range of an oxygen hood that will ensure adequate flushing of CO2
- correct Answer-7-15 L/m
Humidity or heated aerosol provided with oxygen hood should be delivered at what
temp. range - correct Answer-30 - 34 C
Where is the best place to analyze O2 within the oxygen hood and why - correct
Answer-At the infants mouth because O2 has a tendency to settle and the bottom.
(↑FiO2 at bottom than at the top)
How can excessive noise from a nebulizer (air-entrainment) transmitted to the oxygen
hood be reduced so that hearing damage and restlessness in the neonate can be
prevented - correct Answer-Use Air-O2 blender to acheive precise FiO2 (quieter than air
entraiment port) and set aerosol mask at 100%
Why is temperature regulation in the oxygen hood important - correct Answer-If too cool
then O2 consumption will ↑
If too warm then apnea and insensible water loss (dehydration) can occur
[Keep temp. between 30 - 34C]
What is the minimum age for use of a non-rebreather mask - correct Answer-Peds at
least 1 year old
Max FiO2 of NRB - correct Answer-100%
If the reservoir bag NRB collapses completely with each breathe then... - correct
Answer-Flow is insufficient...INCREASE THE FLOW
Troubleshooting a NRB mask whose reservoir bag does not collapse at all with each
breath involves... - correct Answer-1. Proper sealing of mask on face (POOR SEAL IS
MOST COMMON CAUSE)
2. Replace mask due to faulty NRB valve
, If the reservoir bag of an NRB does not collapse with each breathe, and a loud "hissing
sound" is heard form the flow meter then... - correct Answer-the flow is set too high
(reduce the flow)
What O2 device should be used for a pt whose has irregular Vt and erractive RR -
correct Answer-Venturi Mask
In order for venti mask to be effective, what should it accomplish with regard the the pts.
breathing - correct Answer-Meet or exceed pt inspiratory demand
How do you know if a venti mask is meeting or exceeding a pt inspiratory - correct
Answer-Total flow of device must be greater than the pt VE
How do you calculate total flow - correct Answer-Magic Box then add parts.
Sum of the parts x set flow = total flow of device
Compare total flow to pt VE
NC are better suited for neonates or peds?
(Not HFNC) - correct Answer-Peds
What is the achievable FiO2 with a NC on a neonate?
What is the achievable FiO2 with a NC on a ped? - correct Answer-60%
45%
(Peds have higher insp. demands therefore will entrian more room air and ↓ FiO2)
What is the flow rate range for a NC on a neonate - correct Answer-0.25 - 2.0 L/m
Since neonatal flowmeters come in mL/min, what should a neonatal flow meter be set a
to achieve a flow of 0.25 L/m - correct Answer-Set neonatal flowmeter at 250 mL/min
Why are neonatal flowmeters measured in mL/min instead of L/min - correct Answer-To
allow very very small changes in FiO2 to achieve a specific SpO2 and thus facilitate
titration
HFNC can deliver flows in excess of ... - correct Answer-30L/min
How is precise FiO2 achieved with HFNC devices such as a Vapo Therm - correct
Answer-Oxygen-Air is premixed with blender
Although CPAP effect is created with HFNC, it usually does not cause expansion of the
alveoli, there is still a beneficial effect which is... - correct Answer-↓ WOB
Which O2 device is used for neonates once FiO2 is at 60% and the PaO2 remains
below 60mmHg or the pt remains cyanotic - correct Answer-Nasal CPAP
