LIFEPAK 1000 Defibrillator Operating Instructions

that a shock is needed, the AED will prompt,

IF YOU WITNESSED THE ARREST, PUSH

CANCEL

, which provides the opportunity to end CPR early and proceed directly to delivering

a shock.

• The

CPR FIRST

setting prompts the user to perform CPR immediately after the defibrillator is

powered on. The AED will also prompt,

IF YOU WITNESSED THE ARREST, PUSH CANCEL

which provides the opportunity to end CPR early and proceed directly to analysis.

Organizations that choose to implement this option should develop a protocol and provide
training to responders instructing them when to end the initial CPR interval early. Potential
situations for instructing responders to end CPR early include:

• The patient's collapse was witnessed by the responder.

• The responder ascertains that fewer than four or five minutes have elapsed since the patient's

collapse.

• The patient exhibits agonal breathing, an indicator of a short downtime.

• The responder ascertains that CPR of adequate quality and duration has already been

provided before attaching the AED electrodes.

Initial CPR Time

The

INITIAL CPR TIME

option applies when

INITIAL CPR

is set to

ANALYZE FIRST

CPR

FIRST

. It sets the CPR time for that CPR period. The time choices for

INITIAL CPR TIME

are:

120

, and

180

SECONDS

. The default setting is

120 SECONDS

PreShock CPR Time

The

PRESHOCK CPR

time option inserts prompting for CPR when a shockable ECG rhythm is

detected and during the time the AED is charging. It applies only when analysis results in

SHOCK ADVISED

decisions. When

INITIAL CPR

is set to

OFF

CPR FIRST

PRESHOCK CPR

time applies to the first and all subsequent shocks. When

INITIAL CPR

is set to

ANALYZE FIRST

PRESHOCK CPR

time applies to the second and all subsequent shocks. The choices for

PRESHOCK CPR

time are:

OFF, 15,

and

30 SECONDS

. To prompt for CPR only for the time the

capacitor is charging, select the 15-seconds CPR interval. The

SHOCK

button is not enabled

until charging and CPR time are completed. The default setting for

PRESHOCK CPR

time is

OFF

Note:

Although the

SHOCK

button is disabled during the

PRESHOCK CPR

interval, it

becomes active as soon as the

PRESHOCK CPR

interval ends. To minimize the interval

between the final chest compression and shock delivery (while maintaining responder
safety), protocols that select this option should provide specific training and protocols to
address the rapid transition from

PRESHOCK CPR

to shock delivery.

Stacked Shocks

When set to

OFF

, the

STACKED SHOCKS

option inserts prompting for CPR after each (a single)

shock. This eliminates the three-shock stack. CPR is prompted after the shock regardless of the
ECG rhythm. The CPR time following the shock is determined by the

CPR TIME 1

setting

selected. Choices for the

STACKED SHOCKS

option are

OFF

. The default setting is

OFF

When this option is set to

, the defibrillator follows the previously traditional stacked shock

protocol and delivers up to three consecutive shocks, as necessary, without interposed CPR.
