CPAP

In this form of CPAP the positive pressure level is established by the therapist immersing the distal end of the expiratory limb of the circuit below the water surface at a designated level.  Which form of CPAP is it?

• SiPAP
• BiLevel
• Bubble CPAP
• HFNC

Where should the pop-off valve of a CPAP system be placed in regard to patient safety?

• On the dry side of the humidifier
• At the machine to detect disconnection
• As close to the patient's airway as possible
• 6cm from the patient

What form of CPAP is associated with a "wiggle"?

• Bubble CPAP
• SiPAP
• HFNC
• Oscillator CPAP

Which of the following structures is most likely to suffer skin breakdown from improper placement and monitoring of a CPAP device on a neonate?

• Tragus
• Philtrum
• Nasal bone
• Maxilla

You increase the level of CPAP on an infant admitted for RSV to improve oxygenation following blood gas results reflecting a PaCO2 of 45mmHg and PaO2 of 72mmHg.  15 minutes later blood gas results are as follows:  pH 7.33, PaCO2 52mmHg, PaO2 66mmHg.  What could have been the complication?

• FiO2 should have been increased
• There might be a leak in the system
• The CPAP level was raised too high
• The CPAP level was not raised high enough

Why are retractions so prominent in neonates in comparison to large children and adults?

• Because they aren't strong yet
• Neonates have fast respiratory rates
• Neonates have thin and weak musculature and a less rigid thorax
• Neonates have small airways

Which of the following BiPAP settings can influence upper airway stability?

• EPAP
• IPAP
• Rise time
• Mode

The infant airway is funnel shaped.

• False
• True

CPAP stabilizes the chest wall.

• True
• False

Which of the following interventions would be appropriate for a neonate with a RR of 65 while displaying grunting, nasal flaring, cyanosis, and paradoxical chest wall movement with the following blood gas data:  pH 7.30, PaCO2 52mmHg, PaO2 64mmHg, BE -2?

• Intubation and mechanical ventilation
• CPAP
• HFNC
• Suction of the airways
