CAUTIONS
•
Operation of this equipment may be affected by the presence of strong electromagnetic or radio frequency fields such as those
produced by electrocautery.
3.1.3.1. ASYNCHRONIC MODE
Turn on the device and/or select the desired energy by selector switch, marked “1”.
Prepare the paddles with conductive paste or gel.
Press the CHARGE key, marked with “2”, for energy charge.
Place the paddles on the patient (see section “EXTERNAL PADDLE POSITIONING”) and make sure no one is near or in contact with
the patient.
Shock the patient pressing both buttons RED of the paddles, marked with “3”, or pressing the shock key, indicated by “3” in the front
panel.
3.1.3.2. SYNCHRONIC MODE
WARNING! Conscious patients must be anesthetized or sedated before performing synchronized cardioversion.
WARNING! Before performing cardioversion, correct synchronism with R wave must be assess.
Turn on the device and/or select the desired energy by selector switch, marked “1”.
Select the appropriate lead and place the snaps (see section “MENU MONITOR”).
Prepare the paddles with conductive paste or gel.
Press the CHARGE key, marked with “2”, for energy charge.
Press the SYNC key, then the led will light indicating that it is in synchronous mode and also be displayed on the display the text
“SYNC”.
Place the paddles on the patient (see section “EXTERNAL PADDLE POSITIONING”) and make sure no one is near or in contact with
the patient.
A beep will ring simultaneously with the QRS complex; in addition, the SYNC indicator will be shown on the screen.
Hold down both red buttons from the paddle, indicated with “3”, or press shock key on the front panel of the device, also indicated with
“3”, and discharge energy over the patient will be made within 60ms after detected the next R wave (see figure below), for SYNC mode,
R wave must be at least 0.3mV amplitude.
After shock it cancels the SYNCHRONIC mode, the led indicator goes off, and disappear the display the message “SYNC”. In case you
need cardioverter again, you must press again the SYNC key.
3.1.4. TIME OF ENERGY CHARGE
The defibrillator charge time, from fully discharged till its full energy (200Joules) is:
Powered from AC line:
a)
With nominal line voltage (90Vac - 240Vac): 6 seconds.
b)
With line voltage at 90% of the nominal: 7 seconds.
Powered from internal battery:
a)
With the battery fully charged: 6 seconds.
b)
After 15 shocks at maximum energy: 6 seconds.
The time from initial power up, or any operator programming mode till its full energy (200Joules) is:
Powered from AC line:
a)
With nominal line voltage (90Vac - 240Vac): 8 seconds.
b)
With line voltage to 90% of nominal: 9 seconds.
