E Series Options
The following sections describe the E Series options.
12 Lead Option
The ZOLL E Series 12 lead option is used to acquire ECG data needed to assist in the diagnosis of myocardial infarction (“heart attack”), often caused by
a coronary artery occlusion. The 12 lead ECG can be viewed on the display one lead at a time in monitoring and diagnostic bandwidths and printed in the
standard 4x3 format with 12 simultaneously acquired leads.
The 12 lead option provides for the recording, printing and automated analysis of 12 lead ECG using GE Marquette 12SL
 Analysis and supports the
transmission of these reports by fax to a remote location, such as a hospital. In the pre-hospital environment, the 12 lead reports can be faxed to a physician
as the patient is en route to the Emergency Department. As a result, the physician can initiate hospital accommodations immediately, such as activating the
staff of the cardiac catheterization lab, prior to the patient’s arrival and subsequent treatment. Or the patient may be treated in the pre-hospital environment
with thrombolytic agents.
The 12 lead cable is required to produce 12 lead reports. E Series unit must have the 12 lead option installed. All limb leads and V-leads must be connected
to initiate a 12 lead acquisition. Printed 12 Lead bandwidth is user configurable to be either 0.05-150 Hz (per AAMI EC11) or 0.05-40 Hz. The 0.05-40 Hz
bandwidth selection is used to reduce noise artifact in the high end of the diagnostic frequency range. Reports can be printed in a standard 4x3 or Cabrera
format. Faxed reports can be configured in a 2x6 format in addition to 4x3 and Cabrera formats.
The GE Marquette 12SL Analysis algorithm provides measurements of the 12 lead waveforms along with interpretive statements. The algorithm is
interpretive, not “diagnostic.” (A physician should always confirm interpretive statements. A diagnosis requires a complete clinical assessment including
other modalities, such as a physical examination.) 12SL produces global waveform measurements as well as a measurement matrix containing
measurements on each lead. Both the interpretive statements and measurement matrix are configurable to be printed or not printed.
The acquired 12 lead with 12SL may be faxed to a remote location using landline or cellular phone technology. Specific PCMCIA fax modems are
supported and the modem determines the specific phone compatibility. The E Series supports Group 3 facsimile, Class 1, Class 2 and Class 2.0. 12 lead
reports may be re-printed or re-transmitted using the Patient Records capability. Individual patient records may be selected based on patient ID, date, and
time.
Pulse Oximetry (S P O

)
The ZOLL E Series pulse oximetry option enables the user to continuously, noninvasively, and painlessly monitor the percentage of oxygen saturation of
arterial hemoglobin at a peripheral measurement site (i.e.foot, toe or finger.)
The oximetry sensor contains two light emitting diodes, or LEDs, that transmit red and infrared light through the body’s extremities. A photodetector
receives the transmitted light. Oxygen saturated blood absorbs light differently than unsaturated blood. Thus the amount of red and infrared light absorbed
