Accepted Answer

The high airway pressure alarm activates with a pressure increase 3 cm H₂O over the set pressure.

Question 5

The range of continuous positive airway pressure that the Fisher & Paykel Healthcare Bubble CPAP System can provide is _____ cm H₂O.

Accepted Answer

The Fisher & Paykel Healthcare Bubble CPAP System has a continuous positive airway pressure range of 3-10 cm H₂O.

Question 6

Which alarms remain audible in the standby mode on the CareFusion AirLife Nasal CPAP System Driver?
1)Low flow
2)Disconnect
3)High pressure
4)Low oxygen pressure

Accepted Answer

While in the standby mode,the system will operate normally,with all audible alarms muted except for the high-pressure and low-flow alarms.

Question 7

The Cardinal Health Infant Flow Nasal CPAP System driver can operate on battery power for _____ hours.

Accepted Answer

A lead acid battery is contained within the driver.With a full charge,the driver unit operates for 4 hours on battery power.

Question 8

Which of the following are power sources for the Cardinal Health Infant Flow Nasal CPAP System?
1)12-V direct current battery
2)20-psig compressed-air source
3)50-psig oxygen source
4)Alternating current electrical source

Accepted Answer

The continuous positive airway pressure system uses two high-pressure gas sources (50 psig each),an alternating current electrical source,and a 12-V direct current battery as a back-up electrical power source.

Question 9

Which of the following statements is true concerning the CareFusion AirLife Nasal CPAP System Driver?

Accepted Answer

The internal oxygen cell analyzes the fractional inspired oxygen and automatically calibrates oxygen binding on start-up.Adjusting a probe by 1-cm increments is done for the Fisher & Paykel Bubble CPAP System.Bilevel is available only on the CareFusion Infant Flow SiPAP unit.The CareFusion Infant Flow Nasal CPAP System has a proximal pressure line.

Question 10

The Fisher & Paykel Healthcare Bubble CPAP System requires which of the following power sources?
1)110-V alternating current main power
2)12-V direct current battery
3)Air/oxygen blender
4)Air and oxygen high-pressure gas sources

Accepted Answer

The Fisher & Paykel Healthcare Bubble CPAP System requires an air/oxygen blender to power the unit.Only the humidifier requires the electrical source.

Question 11

When is the oxygen blender on the CareFusion Infant Flow Nasal CPAP System recalibrated?

Accepted Answer

The oxygen blender is automatically recalibrated on start-up.

Question 12

A low battery charge alarm condition on a CareFusion SiPAP is caused by which of the following?

Accepted Answer

The low battery charge alarm activates if battery charge falls below 40%.

Question 13

Which of the following units is able to provide more support than traditional noninvasive continuous positive airway pressure to transition infants and pediatric patients from intubation to successful extubation?

Accepted Answer

The CareFusion Infant Flow SiPAP System can provide noninvasive bilevel airway pressure that can bridge the gap between continuous positive airway pressure and mechanical ventilation.

Question 14

What is the respiratory rate available on the CareFusion SiPAP?

Accepted Answer

The respiratory rate on the CareFusion SiPAP is adjustable from 0 to 150 breaths per minute.

Question 15

Which of the following statements concerning the CareFusion/Infant Flow SiPAP Comprehensive System is not true?

Accepted Answer

The CareFusion Infant Flow SiPAP Comprehensive System can provide only up to 2 hours of operating time if the alternating current power source is lost.The battery requires 16 hours to become fully charged from a discharged state.

Question 16

Patient inspiration causes which of the following to occur on the CareFusion Infant Flow SiPAP System?

Accepted Answer

When the patient makes an inspiratory effort,the flow generator converts the kinetic energy of flow to pressure to stabilize pressure delivery at the patient interface.The unit uses flip-flop fluidic logic.

Question 17

The "comfort-flow feature" on the CareFusion AirLife Nasal CPAP System Driver refers to which of the following?

Accepted Answer

This unit automatically adjusts the gas flow to achieve the desired pressure levels and to compensate for leaks.A constant level of nasal continuous positive airway pressure is maintained.

Question 18

Which of the following statements concerning the use of the Fisher & Paykel Healthcare Bubble CPAP System is true?

Accepted Answer

Large prongs decrease blood flow to the area,causing blanching of the rim of the nostrils.The bubbling in the continuous positive airway pressure generator should be gentle and continuous.If the prongs are too small,there will be an increase in airway pressure,and gas will leak from the system.The prongs should be placed,with the curved side down,into the infant's nostrils.

Question 19

What is the maximum amount of time an alarm condition must persist on the CareFusion Infant Flow Nasal CPAP System for an alarm to be delayed when the ventilator is being set up?

Accepted Answer

Alarms are delayed for 120 seconds after entering the main screen to allow time for ventilator set up.

Question 20

Which of the following is not true of the Hamilton ARABELLA System?

Accepted Answer

The major difference between the ARABELLA and the CareFusion Infant Flow Nasal CPAP Systems lies in the design of their flow generators.
