LIFEPAK 15 Monitor/Defibrillator Operating Instructions
metronome prompts the rescuer to perform CPR at the selected compression to ventilation
(C:V) ratio.
Age-Airway Considerations
The default C:V ratio for the metronome (in both AED and Manual modes) is Adult - No
Airway (30:2) because most patients in cardiac arrest are adults who have an initially
unsecured airway. In Manual mode, the user can choose the most appropriate C:V ratio
based on the patient’s age and current airway status. The Age-Airway selection determines
the C:V ratio of the metronome sounds. The default C:V ratios are shown in the following
table.
Table 22 Default Age-Airway C:V Ratios in Manual Mode
AGE-AIRWAY C:V RATIO
Adult - No Airway* 30:2
Adult - Airway** 10:1
Youth - No Airway*** 15:2
Youth - Airway 10:1
* No Airway = No artificial airway in place
** Airway = Advanced artificial airway in place
*** Youth = Pre-pubescent child
Note:
The compression-to-ventilation ratio selections can be set up according to local
medical protocols. For more information, see the LIFEPAK 15 Monitor/Defibrillator Setup
Options provided with your device.
Activating and Deactivating the Metronome
To activate the CPR metronome in Manual mode:
1. Press
CPR
. The CPR Metronome
menu appears and the metronome is
activated using the Adult-No Airway
default setting.
2. Use the SPEED DIAL to highlight and
select the desired Age-Airway setting.
When the metronome is on, a message
appears in the message area that indicates
the current Age-Airway selection.
Note: If the VF/VT alarm is on, it is suspended when the metronome is on to prevent false
VF/VT alarms. If other vital sign alarms activate when the metronome is on, the visual
indicators occur, but the alarm tone is suppressed until the metronome is deactivated.
