The Ultima Dual Airflow Pressure Sensor™ is intended for use during sleep disorder studies as a
measure of respiratory airflow for recording onto a data acquisition system.
The Ultima Dual Airflow Pressure Sensor™ is a battery-powered pressure transducer that uses
state-of-the-art-miniaturized technology to detect and reproduce waveforms associated with
respiratory airflow from both the nose and mouth. Respiratory pressures are converted into
voltage signals compatible with a variety of data acquisition systems.
The differential pressure system uses either custom Braebon™ cannulas (Model 0589, 0588,
0582s, or others) or standard oxygen (O2) cannulas with the Braebon™ safety filter. The single-
use nasal cannula has a 0.2-micron hydrophobic filter that prevents the spread of contaminants
between patients and prevents moisture damage to the pressure sensor. The cannula attaches to
the positive input of the Ultima Dual Airflow Pressure Sensor™.
The pressure sensor essentially functions as an uncalibrated pneumotachograph. The sensor
detects and amplifies pressure swings from the cannula using a stable pressure transducer
capable of detecting differential pressures in the ±25 cm H2O range. The corresponding voltage is
then output for data acquisition.

The Ultima Dual Airflow Pressure Sensor™ is a differential pressure transducer that detects and
amplifies pressure swings in the cm of H2O range. The voltage corresponding to the
differential pressure is output for data acquisition.
The Ultima Dual Airflow Pressure Sensor™ has three inputs and six outputs with an output range
of volts. With the Ultima Dual Airflow Pressure Sensor™, you can adjust the gain and baseline
controls for both the nasal and oral output channels. The output range will vary according to the
gain and baseline settings you used during recording.

The Ultima Dual Airflow Pressure Sensor™ has three inputs: nasal input, nasal differential input
(CPAP connection), and oral input.
Nasal Input
With the nasal input, you can either combine oral and nasal breathing into one channel using
a single lumen, oral/nasal cannula connected to the nasal input or you can record nasal
breathing only using any nasal cannula connected to the nasal input.
Nasal Differential Input
With the nasal differential input, you can subtract a known pressure from the nasal baseline by
connecting your CPAP circuit to the nasal differential input.
The nasal differential input is your baseline for the nasal input. If you do not connect anything,
then you are using atmospheric pressure as your baseline for your nasal input. However, if
you attach a CPAP circuit to the nasal differential input, then you are using the CPAP pressure
as the baseline instead of atmospheric pressure.
Oral Input
With the oral input, you can record oral and nasal breathing on separate channels using a
dual lumen, oral and nasal cannula connected to both the oral and nasal input.

On the right side of the Ultima Dual Airflow Pressure Sensor™, there are four, 20-turn screws that
allow you to adjust both the gain and baseline settings for both the nasal and oral outputs. The
baseline is set to zero volts in our factory. Under most circumstances, however, you will NOT need
to make adjustments.
Gain adjustment screws
There are two gain adjustments screws: a nasal gain screw and an oral gain screw. The nasal
gain screw allows you to adjust the gain for all the nasal outputs. Similarly, you can adjust the
gain for all the oral outputs with the oral gain screw.
By adjusting the gain or sensitivity, you enlarge or reduce the size of the waveform on the
display of your recording system. You do not change the actual recorded signal.
By turning the gain screw clockwise, you increase the sensitivity to make the signal larger. By
turning the gain screw counterclockwise, you decrease the sensitivity to make the signal
smaller.
Baseline adjustment screws
The baseline is set to zero volts in our factory. Under most circumstances, however, you
will NOT need to make adjustments.
If you do want to make adjustments, there are two baseline adjustments screws: a nasal
baseline screw and an oral baseline screw. The nasal baseline screw allows you to adjust
the baseline for all the nasal outputs. Similarly, you can adjust the baseline for all the oral
outputs with the oral baseline screw.
When you turn the baseline adjustment screw, you change the position of the waveform
on the display of your recording system. You move the waveform further up or further
down on the display so you can view the signal peak-to-peak. The baseline is set to zero
volts in the factory.
By turning the baseline screw clockwise, you move the baseline higher; that is, increase
the baseline voltage. By turning the baseline screw counterclockwise, you move the
baseline lower; that is, decrease the baseline voltage.
Caution: Do NOT adjust the baseline without a voltmeter.

Centred on the face of the Ultima Dual Airflow Pressure Sensor™, there is a Battery Status
Indicator LED. The LED flashes either green or red to indicate the status of the batteries in the
Ultima Dual Airflow Pressure Sensor™. See Table 2 Battery Status.
Usually, the batteries will last about 30 - 50 nights (8-hour recordings) depending on the battery
type used. When the Battery Status Indicator LED blinks red, replace your batteries with new AA
alkaline batteries. See the Troubleshooting section, if the LED is not blinking.

The connection set-up and recorder settings for the pressure sensor depend upon the sleep
recording system you are using:
Warning: Always use a new single-use Ultima Airflow Pressure Cannula
(Model 0589, 0588, 0582s, or others) and a new safety filter (Model 0583) with
each patient. The safety filter is required to prevent the spread of contaminants
between patients and to prevent moisture damage to the pressure sensor.
Caution: To prevent dust contamination to the Ultima Dual Airflow Pressure
Sensor™, keep safety filters attached to the unit at all times and change the
safety filters immediately prior to patient use.

The inputs you use on the pressure sensor depend upon whether you plan to record nasal and
oral breathing on separate channels or on a single channel, record nasal breathing only, or
perform a CPAP titration study in which you subtract a known pressure from the nasal baseline.
• Record nasal and oral
breathing on separate
channels
Using a Braebon™ Ultima Oral & Nasal Dual Lumen
Cannula (Model 0588), connect the safety filters on the
cannula to the nasal and oral inputs.
• Combine nasal and oral
breathing into one
channel
Using a Braebon™ Ultima Oral/Nasal Cannula and filter
(Model 0589), connect the safety filter on the cannula to the
nasal input only.
• Record nasal breathing
only
Using any cannula with a Braebon™ Safety Filter (Model
0583) attached, connect the safety filter on the cannula to
the nasal input only.
• Subtract a known
pressure from the nasal
baseline
1. Connect the CPAP circuit to the Braebon™ Safety Filter
(Model 0583). See Figures 5, 6, and 7 for illustrations of
different CPAP connection options.
2. Connect the safety filter to the nasal differential input on
the Ultima Dual Airflow Pressure Sensor™.
NOTE: You will only be able to affect the baseline on the
nasal output signals.

into the nose and in front of the mouth as illustrated in Figure 8.
Figure 8 Positioning the Cannula
2. Once the nasal/oral prongs are comfortably placed, slide the cannula tubing over the patient’s
ears and down the front of the chest.
3. Slide the cinch tubing toward the neck for a comfortable fit under the chin.
4. Mount the pressure sensor on the wall or bedside table.
Warning: Always use a new single-use Ultima Airflow Pressure Cannula
(Model 0589, 0588, 0582s, or others) and a new Braebon™ safety filter (Model
0583) to prevent the spread of contaminants between patients and to prevent
damage to the pressure sensor.
Caution: If you are mounting the pressure sensor on the wall, mount the unit
upside down to minimize the likelihood of bending or kinking the cannula
tubing.

The Ultima Dual Airflow Pressure Sensor™ contains four 20-turn potentiometers (pots) which
allow for precise adjustment of both gain and baseline settings for the nasal and oral outputs.
Under most circumstances, you will NOT need to make any adjustments.
$GMXVWLQJWKHJDLQ
You can enlarge or reduce the size of the waveform on the display by turning the gain screw
clockwise or counterclockwise respectively. You do not change the actual recorded signal when
you increase or decrease the gain.
7RDGMXVWWKHQDVDORURUDOJDLQ
1. To increase the gain (enlarge the waveform), turn the appropriate gain screw clockwise.
2. To decrease the gain (shrink the waveform), turn the appropriate gain screw counterclockwise.
$GMXVWLQJWKHEDVHOLQH
When you turn the baseline adjustment screw, you change the position of the waveform on the
display of your recording system. By turning the screw clockwise or counterclockwise, you
move the waveform further up or further down on the display so you can view the signal
peak-to-peak. The baseline is set to zero volts in the factory.

1. Using the interface cable appropriate to your recording system, connect a 1 mm keyhole
connector to either the Nasal Airflow and Snoring output or the Oral Airflow and Snoring
output.
2. Connect the voltmeter to the interface cable.
3. Do the following:
• To move the baseline higher, that is increase the baseline voltage, turn the appropriate
baseline screw clockwise.
• To move the baseline lower, that is decrease the baseline voltage, turn the appropriate
baseline screw counterclockwise.
Caution: Do NOT adjust the baseline without a voltmeter.
