Models and Options
The specifications for the different models of the pneumatonometer are found in the General Specifi-
cations section of this manual.
The pneumatonometer is a tonometer that provides the following tests: manual tonometry, pulse
tonometry or tonography.
In the manual mode, the pneumatonometer provides a single pressure value and ends the test when
the probe is removed from the surface of the patient’s eye. The pulse mode provides pressure
output with pulse fluctuations and ends the test after it has read ten ocular pulses or the probe is
removed from the eye surface. The tonography test records changes in IOP when a weighted probe
is held on the cornea for a specified time. The tonography test enables the operator to conduct a
two-minute or four-minute test for each eye.
The Model 30 Pneumatonometer handpiece and probe assembly (Figure 1-6) includes:
1. Tip and membrane assembly (Applied Part)
2. Auto sensor assembly and probe handle
3. Double lumen tubing
4. Quick-flow connector

Installation
Consider the following factors as you find a location for the Model 30 Pneumatonometer:
• When taking tonometry measurements with the pneumatonometer, the patient can be either seated
or supine. When conducting tonography tests, the patient must be supine.
• The console should be close enough to an electrical outlet so that the operator can connect the sys-
tem with the power cord.
• The operator should be in a position to look directly at the contact between the probe and the sur-
face of the eye.
• The operator should be able to see the instrument’s LCD readout and chart recorder easily during a
test.
• This medical device complies with IEC/EN 60601-1-2 Safety Standard for Electromagnetic Compat-
ibility, Requirements and Test. However, if the equipment is operated in the presence of high levels
of EMI or highly sensitive equipment, interference may be encountered and the user should take
whatever steps are necessary to eliminate or reduce the interference.
Pneumatonometer Installation
WARNING: CARE MUST BE TAKEN TO ARRANGE THE CABLES FOR THE ACCESSORIES SUCH THAT THEY DO
NOT PRESENT A TRIPPING HAZARD TO THE EXAMINER OR A DANGER TO THE PATIENT.
WARNING: POSITION THIS INSTRUMENT SO THAT IT IS NOT DIFFICULT TO OPERATE THE DISCONNECTION
DEVICE (PLUG).
1. Set the ON/OFF switch on the front panel to the OFF position (the O is
pushed in). Refer to Figure 1-7.
2. Remove the yellow shipping bracket according to the following steps. Refer
to Figure 1-8.
A. Remove the screw at the top of the air vent and remove the air vent.
B. Loosen the screw that secures the yellow shipping bracket onto the
back of the compressor.
C. Remove the bracket and then tighten the screw.
D. Replace the air vent and secure it using the screw that was removed.
E. Leave the yellow shipping bracket off and store it in a safe place so that
if it is needed for future shipping, it is available.
3. Plug the power cord into the back of the unit and the other end into an electrical outlet that has the
correct input power parameters as indicated in the General Specifications section of this manual.

Pneumatonometer Installation (continued)
4. Remove the probe from its container and place the clean tip and
membrane assembly that was sent with the unit onto the probe, if
one is not already installed. If a tip is not installed, perform the fol-
lowing:
A. Perform the steps of the Disinfection of the Tip and Membrane
Assembly as indicated in the Reprocessing Guidelines section
of this manual
B. Install the tip and membrane onto the probe tip so that the tub-
ing is positioned approximately half way down the metal tube
as shown in Figure 1-9.
Note: The correct installation of the tip and membrane assembly is
that the tubing is installed approximately half way down the metal tube.
5. Plug the other end of the probe tubing into the front panel connector as follows: (Refer to Figure 1-10)
A. Push in the probe connector into its mating connector.
B. Ensure the connection is tight and that there is no sound of leaking air from around the connector.
6. Loosely coil the probe tubing around the probe tray using the cutouts at either end of the tray and place
the probe in the tray so that the tip is not in contact with any other item.
7. If the unit includes the optional footswitch, connect the footswitch cord into the receptacle on the back
panel. Refer to Figure 1-5 for the location of the footswitch receptacle.
8. Make sure that the printer has the correct thermal paper installed properly. If the unit needs thermal
paper installed, refer to the Maintenance section of this manual for the installation instructions.

Quick Verication Check
Verify the operation of the probe and base unit using the calibration
verifier in the Manual mode. Refer to Figure 2-7.
1. Fill the tube of the Calibration Verier up to the line marked 15
mmHg with ltered water.
2. From the Main Menu, touch the Manual IOP icon. A menu screen
will be displayed describing a summary of the Manual IOP mea-
surement process. Touch the OK icon to continue to the Manual
IOP screen.
3. The Model 30 Pneumatonometer will display the OD and OS
menu. Touch the OD or the OS icon and touch the probe of the
unit to the membrane and align the tip of the probe so that white
part of the probe handle is between the red and black lines on the
metal tube. When the probe is between the red and black lines,
the Model 30 Pneumatonometer will be ready to display the aver-
age IOP readings and its standard deviation. Refer to Figure 2-8.
Note: If the unit makes a loud vibration, remove the shipping bracket located on the back of the unit.
Note: The tone will settle to a lower tone when the probe is aligned properly. During an actual test,
the tone will change to a noticeably lower pitch when the standard deviation is below 1.0
mmHg for at least three seconds.
A lower tone change signies that the instrument has acquired usable data.
After the reading is acquired, the probe can be removed from the Calibration Verifier.
Note: If the IOP is not 15 mmHg (± 2.0 mmHg), go to the Troubleshooting section of this manual for
assistance. If the Troubleshooting section of the manual did not help, contact Reichert at the
address or phone number in the Introduction section of this manual.
4. Touch the HOME icon to display the Main Menu.

Operating principle
The Model 30 Pneumatonometer measures intraocular
pressure (IOP) non-invasively through applanation tonome-
try. The Pneumatonometer probe contains a gentle, floating
pneumatic sensor that touches the surface of the anesthe-
tized cornea with the exact amount of applanating force
required to take a tonometry or tonography measurement.
Refer to Figure 3-1.
The sensing element is a lightweight plastic tip covered with
a thin, highly elastic silicone membrane. The tip is mounted
on a floating piston supported by a porous bearing.
A precisely regulated flow of filtered air enters the piston from the Model 30 Pneumatonometer and travels
through the end of the sensor tip until it is blocked by the membrane. When nothing is touching the mem-
brane, air flows to the periphery of the tip, where it escapes through venting ports. However, when the tip
touches the eye, the pressure against the membrane causes it to seal the vents, blocking the escape of
air and building up pressure in the
system. The pressure increases until
it matches the IOP and stops when
the eye is applanated. At this point,
the membrane can no longer maintain
the seal. Any increased back pres-
sure in the system is released through
the venting ports. Applanation is
then automatically maintained by the
pneumatic feedback system. Refer to
Figure 3-2.
The Model 30 Pneumatonometer monitors the back pressure in the sensor and displays a real-time mov-
ing average of the IOP as well as its standard deviation. The Model 30 Pneumatonometer generates an
audible tone to tell you when the most accurate reading is obtained. The tone will change to a noticeably
lower pitch when the standard deviation among IOP readings remains below 1.0 mm Hg for three seconds.
The reading remains on the LCD readout when the probe is removed from the eye.
The Model 30 Pneumatonometer in the tonography mode calculates and displays the C value (aqueous
outflow coefficient) using either a two-minute or a four-minute tonography examination.
