USER’S GUIDE

ANESTHESIA TANK

The PES® is available with a 150 quart tank (Part #

09879) The electroanesthesia

tank has two electrode assemblies. One is permanently ﬁxed to one end of the tank and the other may be placed at varying distances using the guides within the tank interior.

The output cables are attached to each electrode by means of the corresponding connectors. It’s not important which electrode is assigned to either ANODE or CATHODE, as both are electrically isolated from one another. Both electrodes are enclosed within a non-conductive plastic screen to prevent direct accidental contact with the electrode surface.

CARE & MAINTENANCE OF THE ELECTRODES

It may become necessary to clean the electrodes after periods of extended use. Over time, the electrodes accumulate a build-up of oxidation, making settings unpredictable and shortening battery life between recharges. To clean the electrodes, remove the

protective screen covering the electrode plate. On the movable electrode unit, carefully remove the two plastic screws on the outer edges of the top handle assembly. The electrode and handle can be slid out of the screen assembly. On the ﬁxed electrode unit, carefully remove the four (4) screws that hold the screen to the electrode and put the screen aside. Remove the two (2) stainless steel screws holding the electrode plate to the top mounting bracket. Remove any oxidation with an abrasive pad or sandpaper. It is not recommended that you use any cleaning chemicals or solvents, as they may remain on the electrode assemblies and unintentionally contaminate the electroanesthesia tank. Assemble both units in reverse order, taking care not to damage or crossthread the plastic screws.

ELECTROANESTHESIA TANK

STORAGE POUCH

Inside of the lid of the control box is a pouch for the storage of the output cables, remote switch and manual for the PES®. It is constructed of tough, water resistant nylon and features a hook-and-loop closure system on the protective ﬂap. Care should be taken not to overﬁll the pouch with too many items as it could interfere with the closing of the lid.

The pouch may be removed for cleaning and reattached using the hook-and-loop retention system inside the

lid. While we have taken great

care to ensure that the PES® is safe to use near water, it is not designed to be used in the rain, where it could be splashed with water and/or should never be immersed in water.

Never use the PES® if it is wet. Dry unit off with a dry cloth before operating.

If necessary, wipe control panel surface with a moist towel. Solvents or cleansers may damage the control panel or controls. Avoid spilling liquids on the panel as they may damage internal components.

OVERFLOW STANDPIPE

Included with the PES® anesthesia tank is a standpipe that allows users to replenish the fresh water in the tank by running a hose into it, while letting the over-ﬂow water vent safely out the tank’s drain hole.

The 90˚ elbow is attached to the drain from the inside of the tank and the resulting overﬂow goes out the top of the standpipe, while maintaining desired water level. The amount of water in the tank can be adjusted accordingly using different lengths of vertical pipe.

To attach the standpipe to the outlet drain, press the elbow over the drain tube until it can’t go any further.

It is important that the standpipe is not in place when the PES® tank is in transit. Otherwise, it may be damaged by items shifting around inside the tank during shipping./

OPERATIONS

INTERACTING WITH THE PES

Once the unit is turned on, a series of buttons and the centrally located display on the front panel of the device are used to interact with the PES® and to program the electrical doses to be output.

LOAD SETUP, SELECT, SAVE SETUP

The LOAD SETUP button is used to review the various electrical parameters deﬁning a dose. The PES® is pre-programmed with 10 stored, predeﬁned doses (See PREPROGRAMMED DOSES, SPECS.).

After pressing LOAD SETUP, the  and  buttons are used to scroll through the predeﬁned doses (deﬁned by sets of electrical parameters), and the SELECT button is used to load the set of parameters for use. These parameters can be modiﬁed by the user and, if desired, these new parameters can be stored for recall.

The dose to be delivered is programmed by the user and is deﬁned by PULSE TYPE, TIME, VOLTS, FREQ, and DUTY CYCLE.

7 2015

Use the  and  buttons to review the parameters and SELECT to load the parameters into memory. Display messages will prompt the user for the required input. After all parameters have been reviewed, press SAVE SETUP, use the  and  buttons to select the memory location (page) where the newly deﬁned dose will be saved, press SELECT. Use the SAVE SETUP button to save the settings. Up to 10 sets of parameters (doses) can be saved into memory.

Note: Because there is a potential for interactions among the electrical parameters deﬁning a “dose”, a review of ALL dose parameters is required when a change is made to any of the parameters deﬁning a dose (PULSE TYPE, TIMER, VOLTS, FREQ, DUTY CYCLE).

Use the 5 and 6 buttons to review the parameters available for use. Use SELECT to load settings into memory.

PULSE TYPE

The “PULSE TYPE” button provides options for type of electric current output by the PES®. After pressing PULSE TYPE use the  and  buttons to scroll through the choices. When the desired output is displayed on the screen, press SELECT to load the option into memory.

Options for output: Ramped DC, Standard pulsed DC, and Bursts of pulses.

RAMPED-DC

This is when the output ramps up from zero to maximum (voltage level programmed by the user) over a period of 1 second. This term applies to continuous DC only and not to pulsed waveforms.

When using the dose TIMER, upon completion of the exposure, the ramped DC output will also decrease back to zero over a period of 1 second. Total exposure time includes the periods for ramping the output up and down; minimum total exposure time is 2 seconds.

When output is controlled manually (via remote switch), upon activation of the remote switch the output current starts low and takes 1 second to reach the

selected maximum; if the output voltage was set for 100 volts the output would take 1 second to raise the voltage to 100 volts level. The output will remain at this level until interrupted by release of the switch. Release of the remote switch deactivates the output immediately. Example: If the pulse timer is disabled when using Ramped DC, the DC output increases from 0 to the prescribed voltage level over a period of 1 second, when the remote switch is activated. The output will remain at this level until the remote switch is deactivated (released). The output immediately decreases to zero upon release of the remote switch.

OPERATIONS

PES® Control panel with central display

If the pulse timer is enabled, the output increases from 0 to the prescribed voltage level over a period of 1 second, remains at that level for exposure time minus 1 second, then decreases to 0 over a period of the ﬁnal second.

If, however, the remote switch is released before the exposure-time has elapsed the output is immediately turned off.

STANDARD PULSED DC

Output immediately goes to maximum voltage and stays constant for the entire pulse duration, then drops to zero. This type of pulse is known as “rectangular”.

BURST OF PULSES

Output is a series of dual-frequency rectangular pulses. This type of output may be referred to as dual-frequency pulsed DC, gated burst pulsed DC, or Complex Pulsed System. The pulses occur at two frequencies, an inner (burst) frequency and an outer (cycle).

USER’S GUIDE

CONTROLS & SETTINGS

VOLTS

The amplitude of the PES® output can be varied between 20 and 400 volts, in 5 volt increments. After pressing VOLTS, use the  and  buttons to scroll through the available voltages. Press SELECT to load the voltage setting into memory.

FREQ

Multiple options available are for the frequency of the pulsed DC output by the PES®. Pulse frequency can be varied between 5 Hz and 100 Hz, in increments of 5 Hz, and then 250Hz, 500Hz and 1000Hz. After pressing FREQ, use the  and  buttons to scroll through the frequency options. Press SELECT to load the desired frequency setting into memory.

When the Pulse-Type is Burst-of-Pulses the Burst Frequency (inner frequency) is displayed ﬁrst followed by the Cycle (outer) Frequency. Each frequency must be selected individually by using the  and  buttons.

When the Pulse-Type is Standard Pulse, only the Cycle Frequency is displayed.

When the Pulse-Type setting is RampedDC, the message “Not used in DC” is brieﬂy displayed, the screen then returns to the previous menu.

DUTY CYCLE

Pressing DUTY CYCLE displays the calculated “percentage of time” for the selected pulse type and frequency. When the Pulse-Type is Standard Pulse, the calculated on-time (the ratio of the length of the pulse to the period of the waveform) is displayed. Options for duty cycle vary between 1 and 99%. After pressing DUTY

CYCLE, use the UP () and DOWN () to scroll through the available options. Press SELECT to load the desired setting into memory. When the Pulse-Type is Burst-of-Pulse, the duty cycle of the two frequencies is displayed. The duty cycle of the inner burst is displayed ﬁrst, followed by the frequency of the outer cycle and the duty cycle of the CYCLE frequency is displayed second. When the Pulse-Type is Ramped-DC the message “Not used in DC” is displayed.

TIMER

Termination of the output of the PES® can be automated with the TIMER or controlled manually. The TIMER can be adjusted from 1 to 255 seconds or “disabled”. The output of the PES® is always controlled by the hand switch. When PULSE TYPE is STANDARD PULSES or GATED BURST the minimum time for output is 1 second and the maximum is 255 seconds. When PULSE TYPE is Ramped-DC the minimum time is 2 seconds and the maximum time is 256 seconds: One second is needed to ramp up the voltage and one second to ramp it back down.

DUAL MODE

The PES® can be conﬁgured to output two different doses, in sequence. In this conﬁguration, a secondary dose is delivered following a primary dose, when the primary waveform TIMER elapses on a single activation of the remote switch. Each of the phases of the exposure the primary phase and the secondary phase are programmed by the user using the PULSE TYPE, DUTY CYCLE, FREQ,

9 2015

PES: PORTABLE ELECTROANESTHESIA SYSTEM

TIMER, and VOLTS buttons, as previously described for a single phase output.

Releasing the remote switch at any time will stop the output of the PES.

In Dual-Mode the preﬁx “Pri” is displayed for the Primary dose setting. Pressing “SELECT” advances to display the preﬁx “Sec” for the secondary dose. Pressing “SELECT” again sets the displayed option for the Secondary dose type.

Dual mode requires the pulse TIMER for the primary waveform. Disabling the primary waveform timer disables the dual mode.

CONTROLS & SETTINGS

DEFAULT SETTINGS

The PES® comes with 10 sets of parameters pre-programmed as default doses. The individual parameters of the doses can be changed. The 10 storage locations (identiﬁed on the screen) can be reviewed, changed, and stored in memory for future use, by the user. To restore the factory default settings press the “MENU” button, press the “UP” arrow to cycle to “System Menu 9/10”, “Restore factory default settings?” and then press “SELECT”. Press the “UP” arrow to conﬁrm the operation. When powered on, the unit initializes with the dose settings previously loaded by the user. The dose settings to be used should be reviewed prior to operation of the unit.

MENU GUIDE

1 STATUS DISPLAY

On Startup and at the end of various other menu operations the PES® displays the current Status. There are 3 or 4 Status displays. If a menu button is pressed while in another menu the PES® returns to the status display. The default is to display the current waveform settings such as these:

The up or down arrow (or) will cycle the to one of the other Status displays like these:

2 LOAD SETUP

There are 10 settings in memory. Pressing LOAD SETUP will display one of these settings. The setting number is shown in the upper right corner of the display. The up and down arrows will cycle through all settings from 0 to 9. Pressing SELECT will load the displayed setting, display a message to that effect and return to the Status Display.

Note: For the Dual mode settings the Primary (Pri) waveform is displayed ﬁrst regardless of which arrow is pressed. The Secondary (Sec) wave form is only displayed if the up arrow is pressed while viewing the Primary waveform setting.

Example settings:

3 SAVE SETUP

In the save setting menu only the setting

number is display in the upper right corner. Pressing SELECT will overwrite the setting at that memory location with the current waveform parameter settings. The display will then return to a Status Display.

Example:

4 TIMER

The TIMER button allows the pulse timer to be changed. When the pulse TIMER is enabled the output is only active for the set number of seconds after the output switch is pressed and then the output automatically stops. With the Wave Time disabled the output remains active for as long as the output button is held on.

Pressing the Timer button displays the current setting which can be changed by pressing the up or down arrow until the desired setting is displayed and then pressing SELECT. After pressing SELECT the display will then return to Status Display.

Like most wave settings menus if Dual mode waveform is enabled the ﬁrst display will show the Primary waveform setting for that parameter. Pressing SELECT, whether or not a change is made, will switch the display to the Secondary waveform setting.

11 2015

PES: PORTABLE ELECTROANESTHESIA SYSTEM

PES® MENUS

Note: For dual waveform output to function the Dual mode setting must be enabled and the Primary Wave Timer must not be disabled. The PES® switches from the Primary waveform to the secondary waveform when the Primary Wave Time expires. Even if Dual mode is enabled the output will not switch if the Primary Wave Time is disable. The Secondary Wave Time can be disabled. In that case the output will switch from the Primary waveform to the Secondary waveform when the Primary Wave Time expires and the PES® will continue to output the Secondary waveform for as long as the REMOTE SWITCH is held.

5 PULSE TYPE

Press the PULSE TYPE menu button to select one of the three output waveform types; Ramped DC, Standard (Rectangular Pulses), or Burst of Pulses. On pressing the PULSE TYPE menu button the current setting is displayed. Pressing the up or down arrows changed the display and pressing the SELECT button changes the setting to the one displayed and return the display to Status Display.

If Dual mode waveform is enabled the ﬁrst display will show the Primary Waveform pulse type. Pressing SELECT will set the type for the Primary waveform and the display will then show the Secondary waveform type. Pressing SELECT again would set the Secondary waveform type and the display will return to Status Display. Graphical display are shown only for example and are in no speciﬁc order.

6 VOLTS

Pressing the VOLT menu button displays the current voltage setting. The up and down arrows change the voltage value in the display and the SELECT button sets that voltage for the waveform. If Dual mode is enabled the display ﬁrst shows the Primary wave voltage. Pressing SELECT sets the voltage for the Primary and switches the display to show the Secondary waveform voltage setting which can be changed with the arrow buttons and set

with the SELECT button.

7 FREQ.

Pressing the FREQ. button displays the current frequency setting, if the pulse type is set for DC, in which case the display moves to the next waveform of a Dual mode setting or brieﬂy displays an error message and then returns to Status Display. With some frequency displays, the bottom line of the display also shows the calculated width of the pulse in milliseconds using the current setting for Duty Cycle. The displayed waveform frequency setting can be varied up or down with the up or down arrows and the setting of the waveform is changed to that displayed value when the SELECT button is pressed. The range of frequencies may be limited by the current Duty Cycle setting, as the PES® has limits for pulse width.

If BURST OF PULSES wave type is set, the ﬁrst display in the frequency menu is for the Burst Frequency. Pressing SELECT sets that frequency and switches the display to the Cycle Frequency display where it can be raised, lowered or left unchanged. Pressing SELECT again would then set the Cycle Frequency and the display would return to Status Display.

12www.smith-root.com

USER’S GUIDE

If Dual mode is enabled the ﬁrst display shows the frequency setting of the Primary waveform. If that waveform is a Burst of Pulses type the display would show the setting of the Burst Frequency of the Primary Waveform otherwise the display will simply show the Cycle Frequency. Changes to the displayed setting can be made with the up or down arrows. Pressing SELECT would save that setting and change the display to the next menu item.

Menu items follow the following order depending on the Dual mode setting and the Pulse Type settings. The display cycles to the next menu item when SELECT is pressed.

• Cycle Frequency > Status Display

• Burst Frequency > Cycle Frequency >Status Display

• Primary Cycle Frequency > Secondary Cycle Frequency > Status Display

• Primary Burst Frequency > Primary Cycle Frequency > Secondary Cycle Frequency > Status Display

• Primary Cycle Frequency > Secondary Burst Frequency > Secondary Cycle Frequency > Status Display

• Primary Burst Frequency > Primary Cycle Frequency > Secondary Burst Frequency > Secondary Cycle Frequency > Status Display

• Primary Cycle Frequency > Status Display

• Secondary Cycle Frequency > Status Display

• Primary Burst Frequency > Primary Cycle Frequency > Status Display

• Secondary Burst Frequency > Secondary Cycle Frequency > Status Display

If one of the waveform types was set to Ramped DC in the last four sequences, the menu state that would have displayed and that set’s waveform frequency would be skipped.

Note that in DUAL MODE, if the Primary wave Pulse Type is set to Ramped DC, the frequency menu starts with the frequency setting of the Secondary waveform. The following graphical displays are shown only for example and are in no speciﬁc order.

8 DUTY CYCLE

The DUTY CYCLE button is use to view and set the duty cycle, percent of the wave cycle (where the output is at the set voltage). If the pulse type is BURST OF PULSES, the DUTY CYCLE button sets the number of pulses in a burst. The pulse width, calculated using the current frequency setting, is shown on the last line of the DUTY CYCLE display.

If the wave type is set for DC and DUAL MODE is not enabled or the secondary wave type is also DC, an error message is shown brieﬂy before returning to Status Display.

If the wave type is set for STANDARD PULSE than the current waveform’s duty cycle setting is displayed.

Changes to the displayed setting can be made with the arrow buttons, limited by the currently set frequency, and the PES®’s

PES® MENUS

pulse width limitations. The SELECT button saves that display setting and the display returns to the Status Display.

If the current pulse type is BURST OF PULSES, the ﬁrst display shows the number of pulses per burst. The number shown can be changed with the arrow keys. After the parameter is set with the SELECT button, the display will show the current duty cycle setting. This displayed setting can also be changed with the arrow keys and selected with the SELECT button.

As in other menus if Dual mode is enabled the display will show the setting(s) of the Primary waveform, which can be changed with the arrow keys. After pressing the SELECT button, the Secondary wave’s setting will be displayed. After pressing the SELECT button for the secondary waveform’s duty cycle, the display returns to Status Display. The menu cycles through the following items based on the setting of Dual mode and Pulse Type(s) with each press of the SELECT button.

• Duty Cycle > Status Display

• Pulses/Burst > Burst Duty > Status Display

• Primary Duty Cycle > Secondary Duty Cycle > Status Display

• Primary Pulses/Burst > Primary Burst Duty > Secondary Duty Cycle > Status Display

• Primary Duty Cycle > Secondary Pulses/ Burst > Secondary Burst Duty > Status Display

• Primary Pulses/Burst > Primary Burst Duty > Secondary Pulses/Burst > Secondary

Burst Duty > Status Display

• Primary Duty Cycle > Status Display

• Primary Pulses/Burst > Primary Duty Cycle > Status Display

• Secondary Duty Cycle > Status Display

• Secondary Pulses/Burst > Secondary Duty Cycle > Status Display

The last four cycles occur when either the Primary or the Secondary wave type is set for DC. Graphical display are shown only for

example and are in no speciﬁc order.

9 MENU BUTTON

The Menu Button allows access to a set of system operating parameters. The menu always starts with the same parameter and cycles forward with the up arrow and backward with the down arrow. In most menu items the display shows the parameter and the setting change that would occur if the SELECT Button is pressed. To leave the setting unchanged cycle to another menu parameter with the arrow buttons or abort the System Menu by pressing the menu button again and the display will return to Status Display. If the SELECT button is pressed the system setting is changed a message may be brieﬂy displayed before the display returns to the Status Display.

PULSED DC WAVEFORMS

The Pulse Width of these waveforms are the duty cycle times the Period. For a standard waveform the duty is multiplied by the Cycle Period but for a Burst Waveform the duty is multiplied by the Burst Period. For the Standard wave the Pulse Width would be 0.25 times 200 milliseconds which is 50 milliseconds. The Pulse Width for the Burst Waveform would be the duty cycle time the Burst Period, 0.50 times 50 milliseconds or 25 milliseconds.

Figure 1

Figure 1 shows a graphic representation of two pulsed DC waveforms. The top waveform is a Standard Pulsed Waveform with a Cycle Frequency of 5 Hertz and a 25% duty cycle. The bottom waveform depicts a Burst of 3 pulses with a burst frequency of 20Hz, a duty cycle of 50% and a cycle frequency of 5 Hertz.

Other characteristics of a Pulsed DC Waveform are the Period and the Pulse Width.

The Period of a waveform is simply the inverse of the Frequency. For the Standard Pulse in Figure 1 the period is 1-second divided by 5-Hertz which is 200 milliseconds. The Cycle period of the Burst Waveform of Figure 1 is the same as the cycle period of the standard waveform: 200 milliseconds. The Burst Period is 1-second divided by the burst frequency of 20-Hertz which make the Burst Period 50 milliseconds.

19 2015

When selecting the parameters for a waveform it is best to determine, in advance, the setting that will produce the desired output. When changing the settings of an existing waveform, consider the side effect that a change, such as frequency, will have on another characteristic, such as pulse width. Note also that when conﬁguring for a burst of pulses that the cycle period must be greater than the product of the burst period time the number of pulses. (While in theory the relation may be greater or equal, but the resultant waveform would then be identical to a standard waveform. The Burst waveform in Figure 1 could conceivably have 4 pulses in each burst but that would make it a standard wave at 20hz and in reality the timing granularity may not allow it.)
