CAUTION:Use of other oxygen sensors may cause improper oximeter
performance.
CAUTION:Unintended movement may occur if the casters are not locked. The
operator should lock casters during use of the machine.
CAUTION:Unsecured devices may slide off the top shelf. Devices should be
securely attached to the top shelf.
CAUTION:The voltage on the auxiliary outlets is the same voltage as the outlet
into which the A5/A3 machine is plugged. Ensure that devices plugged
into the auxiliary outlets are rated for the same supply voltage as the
A5/A3.
CAUTION:During the transport and storage of the vaporizer, block the gas inlet
and outlet of the vaporizer with plugs to prevent foreign substances
from entering the vaporizer.

Spirometry loops reflect patient lung function and ventilation. They also indicate other related
parameters such as compliance, over-inflation, breathing system leak, and airway blockage.
The system provides three types of spirometry loops: pressure - volume loop (see FIGURE 3-18), flow volume loop (see FIGURE 3-19) and pressure - flow loop (see FIGURE 3-20). Loops data comes from
pressure and flow data. Only one loop is displayed at a time.
The Spirometry tab displays four softkeys: Loop Type, Show Reference, Save Loop, and Review Loops.
3.5.1Loop Type
The Loop Type selection is used to select pressure - volume loop, flow - volume loop or pressureflow loop to display on the Spirometry screen. Default loop type is pressure - volume loop.

System InterfaceSpirometry Tab (A5 Only)
3.5.2Show Reference
The Show Reference softkey can be selected only after a baseline has been saved via the Save Loop
softkey.
The Show Reference softkey (see FIGURE 3-21) is used to select and display a saved baseline loop,
reference loop, or no loop (Off ) in the spirometry loop window, overlapped with the currently
plotting loop. Only the four most recently saved reference loops are listed chronologically.
When a reference loop or baseline loop is selected to display in the spirometry loop Window, the
time stamp will also be displayed.
3.5.3Save Loop
Select the Save Loop softkey (see FIGURE 3-21) to save the currently plotting loop (including its
numeric data) as either a baseline loop or reference loop. Only one baseline loop and up to four
reference loops can be saved. Additional plotting loops can be saved to replace the baseline loop or
reference loops. Only the four most recent reference loops are saved.
The saved baseline or reference loop can be reviewed with its numeric data (via Review Loops
softkey) or displayed with the currently plotting loop on the same graph for comparison (via Show Reference softkey).
NOTE:A reference loop cannot be saved without first saving a
baseline loop. The A5 System will always makes the first saved
loop as the baseline loop if no previous loops have been saved.
Afterward, additional loops can be saved either as a baseline
replacement or as a new reference loop.
To save a baseline loop:
1. From the main screen, select Spirometry tab > Save Loop softkey.
If there is no baseline loop saved in memory, the currently plotting loop will be saved
automatically as the baseline loop.
2. If a baseline loop is already saved in memory, a dialog box will appear with the choices of
“Baseline“ and ”Reference“. S el ect ” Baseline”. A confirmation dialog will be displayed with
the text “Selecting Yes will replace the currently saved Baseline loop. Do you want to proceed?” If “Ye s ” is selected, the currently saved baseline loop will be replaced. If “No” is
chosen, the save will be aborted.
To save a reference loop:
1. From the main screen, select Spirometry tab > Save Loop softkey. If a baseline loop is
already saved in memory, a dialog box will appear with the choices of "Baseline" and
"Reference". Select "Reference".
A maximum of four (4) sets of reference loops plus one (1) Baseline loop and corresponding numeric
data can be saved.
When the maximum of four (4) loops is reached, and the user attempts another save, a confirmation
dialog will be displayed with the following text, “Selecting Yes will replace the oldest reference loop. Do you want to proceed?” If “Yes ” is chosen, the oldest data will be removed as the new data
is added. If "No" is chosen, the save will be aborted.
3.5.4Review Loops Button
Selecting the Review Loops softkey (see FIGURE 3-21) displays the Review Loops screen (see

Loop Type: The Loop Type softkey is used to choose the type of loop to review. The choices are:
Pressure - Volume, Flow - Volume and Pressure - Flow. Default loop type is Pressure - Volume
loop.
Delete Loop: The Delete Loop softkey is used to delete a selected reference loop. When a reference
loop is deleted, the newer reference loops will shift to the left. The Delete Loop softkey will be
disabled (grayed out) if no reference loops have been saved. The baseline loop cannot be deleted. It
can only be replaced by another baseline loop.
