1500 Patient Monitor® Quick reference card

Set-Up Procedure

1. Attach ECG cable, SPO2 cable, Blood Pressure Hose, Temperature cable, and other accessories (if applicable) to right-hand side of the Welch Allyn 1500 Patient Monitor®.

2. Ensure proper lead preparation. Attach lead wires to the electrodes before applying them to the patient. Apply the electrodes to the patient in the proper locations.

3. Turn on the device by pressing the power button located on the front/ right-hand side of the device

4. Device shows up to six waveforms at once (etCO2, IBP, and ST must all be turned on for six waveforms)

a. To Change Waveforms i. Press the Setup button ii. Select Waveforms iii. The waveforms 1 through 6 are conﬁgured through the pull-

down menus.

iv. Set the amplitude for each waveform according to preference

and signal strength. Set the sweep speed according to preference and patient.

v. Select OK to save.

NOTE: The RESP and CO2 sweep speed values are not conﬁgurable, and only

ECG leads are available for waveform 1.

5. Ensure the monitor is in the appropriate Patient Mode: The patient mode is displayed in the lower front/ right hand corner of the device. To change patient mode:

a. Press the Setup Button b. Select Patient Mode. c. Highlight Adult, Pediatric, or Neonate and press trim knob. d. Select OK to save.

NOTE: Neonatal: Birth through 28 days, Pediatric: 29 days through 12 years,

Adult: 13 years and older.

To Admit A Patient Hard-Wired

1. Ensure that you connect the proper monitor network cable to the proper wall jack. There are two hardwired site labels: a blue one used for the Propaq monitor serial cables, and a green one used for the Ethernet devices. Once the Ethernet cable is connected to the wall jack, connect the other end of the Ethernet cable into the back of the device.

2. When the monitor completes the connection to Acuity, the network connection icon screen.

3. The patient data can be changed at the monitor or at Acuity. When conﬁrmed the patient data is synchronized for both the monitor and Acuity. When Acuity is enabled but not connected, the patient information menu option is not given. NOTE: When the device is connected to Acuity, the Arrhythmia/ST menus are not available on the

device as this is done by Acuity.

4. Once connected, the room number is set by the system bed ﬁle and cannot be changed at the device or Acuity.

will appear in the lower right hand corner of the

Appears when there is a loss of connection.

5. Standby, Discontinue Monitoring, Discharge a. When Standby

select Standby, Discontinue Monitoring, or Discharge.

b. For Conﬁrmed Patients

i. Standby: Pressing “Standby” the device will go into a

standby mode. The monitor will read “Standby Mode, Press any key to resume monitoring”. The waveform at Acuity will go into a Blue Patient Disconnected State.

ii. Returning from Standby:

1. The user will be prompted to conﬁrm the same patient.

2. If no is selected, the patient data is deleted.

c. For Unconﬁrmed Patients

i. You will need to acknowledge that you will lose data

if you decide not to conﬁrm the patient before entering into Standby or Discontinue monitoring.

d. Discontinue Monitoring: When you press “discontinue

monitoring” at the 1500, the waveform is removed at Acuity and the patient is no longer monitored. There is no longer an established connection between the device and Acuity.

e. Discharge: When you press “discharge” at the 1500, the

waveform is removed at Acuity, and the patient shows discharged in the patient list. There is no longer an established connection between the device and Acuity.

6. Discharge a patient at Acuity a. Click on the Patient List Icon b. Select patient to be discharged by highlighting name c. Click Discharge. d. Click Discharge again after verifying patient to be discharged.

NOTE: The system does not reestablish a connection until you

press resume. Then the device takes the user through the initial power-on steps.

NOTE: This is a hardwired device. The patient must be

discontinued from monitoring before you can discharge the patient from the Patient List at Acuity. Also as this is a hardwired device, there is no end-tele at Acuity for this device.

NOTE: The monitor sends a 12-lead resting ECG automatically

to Acuity when taken.

in order to avoid moisture buildup and sampling line occlusion, remove the sampling line luer connector from the monitor.

b. Replace the sampling line according to hospital protocol

or when a blockage is indicated by the monitor.

c. When connecting a sampling line to the monitor, screw

the sampling line connecter clockwise into the monitor CO2 port until it can no longer be turned.

d. When the Caution message “Blockage!” appears on the

screen indicating that the ﬁlter line which is attached to the handheld monitor is blocked, the monitor’s CO2 pump will stop pumping the patient’s breath into the monitor for testing. i. Disconnect and reconnect the ﬁlter line. ii. If the message still appears, disconnect and replace

the ﬁlter line. Once a working ﬁlter line is attached to the handheld monitor, the pump will automatically resume operation.

Measuring Respirations

1. The RR measurement ﬁeld is not displayed if the etCO2 ﬁeld is active. If the RR is measured via the ECG instead of etCO2, the etCO2 measurement ﬁeld must be deactivated as follows: a. Press the Setup button b. Select Parameters c. Deactivate etCO2 by selecting “No”.

NOTE: The RR signal is measured via the R (RA) and F (LL)

electrodes of the ECG cable (impedance measurement). After the patient is connected, about 30 seconds can elapse before a reliable value is displayed.

the trim knob. d. Press the trim knob to display the IBP menu. e. Select Zero Set with the trim knob and press to carry out

the zeroing. f. The message “P1 Zeroing” appears followed brieﬂy by

“P1 Zero OK”.

NOTE: Carefully read the manufacturer’s instructions before

using the invasive blood pressure kit.

NOTE: When applying the kit to the patient, make sure that

absolutely no air penetrates the system.

NOTE: The kit and operating procedure vary according to

manufacturer. Please consult the manufacturer’s documentation for connection.

NOTE: P1 is the only connection that can determine the HR/PR source.
