Question 1

When using the BirdMark 7A ventilator, manipulating the flow-rate control to increase the flow will cause the:
I. tidal volume to decrease
II. tidal volume to increase
III. inspiratory time to increase
IV. inspiratory time to decrease

Accepted Answer

Increasing the flow rate on a ventilator like the BirdMark 7A will increase the tidal volume because more air is delivered to the patient per breath. It will decrease the inspiratory time because the higher flow rate fills the lungs more quickly, thus reducing the time needed for each inspiratory cycle.

Question 2

When using the BirdMark 7A ventilator, manipulating the flow-rate control to decrease the flow will cause the:
I. tidal volume to decrease
II. tidal volume to increase
III. inspiratory time to increase
IV. inspiratory time to decrease

Accepted Answer

Decreasing the flow rate on a ventilator like the BirdMark 7A will result in a decrease in tidal volume because less air is being delivered per breath. Additionally, the inspiratory time will increase because it takes longer to deliver the set volume at a lower flow rate.

Question 3

Accepted Answer

The answer of The flow-rate control on the BirdMark 7A...

Question 4

Accepted Answer

The answer of The spring tension on the venturi gate...

Question 5

You are using a BirdMark 7A ventilator for IPPB therapy. You notice that before the ventilator delivers a breath, the pressure manometer indicates a -8 cmH₂O. What control should you manipulate?

Accepted Answer

The negative reading on the pressure manometer indicates that the patient is not initiating a breath, and the ventilator is triggering a breath based on the sensitivity setting. Therefore, manipulating the sensitivity control is necessary to adjust the triggering of breath delivery.

Question 6

When using a BirdMark 7A, changing the pressure control to increase the pressure will cause the:
I. tidal volume to decrease
II. tidal volume to increase
III. inspiratory time to increase
IV. inspiratory time to decrease

Accepted Answer

Increasing the pressure control on a BirdMark 7A will increase the tidal volume (II) because more pressure allows more air to be delivered to the patient. It will also increase the inspiratory time (III) as it takes longer to reach the higher pressure.

Question 7

What flow pattern is delivered when the air mix control is pushed in and the BirdMark 7A is operating on source gas (venturi not being used)?

Accepted Answer

When the air mix control is pushed in and the BirdMark 7A is operating on source gas (venturi not being used), the flow pattern delivered is rectangular.

Question 8

The apnea (expiratory timing) control should not be used during intermittent positive-pressure breathing (IPPB) therapy, due to:

Accepted Answer

The apnea (expiratory timing) control may cause asynchrony with the patient's own respiratory pattern during IPPB therapy, as the machine is delivering pressure and controlling the timing of each breath. It is better to allow the patient to control their own breathing pattern during IPPB therapy.

Question 9

Peak flow through the BirdMark 7A when using the venturi (air mix) can be up to:

Accepted Answer

The BirdMark 7A ventilator, when using the venturi system for air mixing, can achieve a peak flow of up to 80 L/min.

Question 10

Sensitivity is adjusted in the BirdMark 7A ventilator by:

Accepted Answer

The BirdMark 7A ventilator adjusts sensitivity by altering the magnetic attraction against a diaphragm, which controls the effort required by the patient to trigger the ventilator.

Question 11

The center body of the BirdMark 7A ventilator contains:
I. the ceramic switch and clutch plates
II. the venturi
III. the timing cartridge
IV. the flow-rate control

Accepted Answer

The BirdMark 7A ventilator's center body houses the ceramic switch and clutch plates, the venturi, the timing cartridge, and the flow-rate control, making all four components integral to its operation.

Question 12

You are using the BirdMark 7A for IPPB therapy. What prevents gas from escaping from the circuit to the ambient air during inspiration?

Accepted Answer

The exhalation valve prevents gas from escaping from the circuit to the ambient air during inspiration by only allowing gas to flow out during expiration. Options A, B, and D do not prevent gas from escaping during inspiration.

Question 13

The venturi gate on the BirdMark 7A will close when pressure in the pressure chamber reaches approximately:

Accepted Answer

The answer of The venturi gate on the BirdMark 7A...

Question 14

Pressure is adjusted in the BirdMark 7A ventilator by:

Accepted Answer

The BirdMark 7A ventilator adjusts pressure by altering the magnetic attraction against a diaphragm, which controls the pressure delivered to the patient.

Question 15

When using the BirdMark 7A ventilator, changing the pressure control to decrease the pressure will cause the:
I. tidal volume to decrease
II. tidal volume to increase
III. inspiratory time to increase
IV. inspiratory time to decrease

Accepted Answer

When pressure control is decreased, tidal volume will also decrease as there is less pressure available to deliver the set tidal volume. Inspiratory time will also decrease as the breath is delivered faster due to less pressure being delivered.

Question 16

F_IO₂ delivery increases during inspiration while the BirdMark 7A is operating using air mix. Which of the following contribute to this fact? I. Increasing pressure in the pressure chamber decreases air entrainment. II. At 12 cmH₂O, the venturi gate closes. III. After about 12 cmH₂O, gas flow through the circuit is source gas. IV. Excess flow (source gas) is directed through the timing cartridge.

Accepted Answer

I. Increasing pressure in the pressure chamber decreases air entrainment, which means more source gas is used, leading to an increase in delivery during inspiration.
II. At 12 cmH2O, the venturi gate closes, allowing less air entrainment and more source gas to be used, which increases delivery during inspiration.
III. After about 12 cmH2O, gas flow through the circuit is source gas, which increases delivery during inspiration.
IV. Excess flow (source gas) is directed through the timing cartridge, which helps regulate the delivery and ensures accurate tidal volume. However, this does not directly contribute to the increase in delivery during inspiration.

Question 17

You are using a BirdMark 7A ventilator during IPPB therapy. You need to decrease tidal volume. How can you decrease tidal volume without altering inspiratory time?
I. increase the pressure
II. decrease the pressure
III. increase the flow rate
IV. decrease the flow rate

Accepted Answer

To decrease tidal volume without altering inspiratory time on a BirdMark 7A ventilator during IPPB therapy, you would decrease the pressure (which directly reduces the volume of air pushed into the lungs) and decrease the flow rate (which reduces the speed at which air is delivered, thus reducing volume). Both adjustments lead to a decrease in tidal volume without changing the duration of inspiration.

Question 18

For intermittent positive-pressure breathing (IPPB) therapy, when adjusted correctly the sensitivity on the BirdMark 7A should be set for:

Accepted Answer

The sensitivity on the BirdMark 7A should be set for 1 to 2 cmH2O below ambient for IPPB therapy to allow the patient to trigger the ventilator easily.

Question 19

You are using a BirdMark 7A ventilator during IPPB therapy. You need to increase tidal volume. How can you increase tidal volume without altering inspiratory time?
I. increase the pressure
II. decrease the pressure
III. increase the flow rate
IV. decrease the flow rate

Accepted Answer

Increasing the pressure and the flow rate will increase tidal volume without altering inspiratory time. Decreasing the pressure or flow rate would decrease tidal volume.

Question 20

Which of the following characteristics are true regarding the BirdMark 7A ventilator's classification?
I. electrically powered
II. pneumatically powered
III. time or pressure triggered
IV. pressure cycled

Accepted Answer

The BirdMark 7A ventilator is pneumatically powered, can be time or pressure triggered, and is pressure cycled.
