Indications for Use
Ventilation
The ZOLL Z Vent ventilator is indicated for use in the management of infant through adult
patients weighing greater than or equal to 5 kg with acute or chronic respiratory failure or
during resuscitation by providing continuous positive-pressure ventilation. The ZOLL Z Vent
ventilator is appropriate for use in hospitals, outside the hospital, during transport and in severe
environments where they may be exposed to rain, dust, rough handling, and extremes in
temperature and humidity. With an appropriate third-party filter in place, they may be operated
in environments where chemical and/or biological toxins are present. When marked with an
“MRI conditional” label, the ZOLL Z Vent ventilator is suitable for use in an MRI environment
with appropriate precautions. The ZOLL Z Vent ventilator is intended for use by skilled care
providers with knowledge of mechanical ventilation, emergency medical services (EMS)
personnel with a basic knowledge of mechanical ventilation, and by first responders under the
direction of skilled medical care providers.
Pulse Oximetry (SpO2)
The ZOLL Z Vent ventilator pulse oximeter with Masimo SET technology is intended for use
for continuous noninvasive monitoring of the oxygen saturation of arterial hemoglobin (SpO2),
and pulse rate. The pulse SpO2 oximeter and accessories are indicated for use with adult and
pediatric patients during both no motion and motion conditions, and for patients who are well
or poorly perfused, in hospitals, hospital-type facilities, or in mobile environments.

Warnings
General
•The Z Vent ventilator is intended for use by qualified personnel only. You should read this
manual before using the device.
•Before using the ventilator on a patient, you must test the device in its normal configuration
to ensure proper operation.
•Do not modify this equipment without authorization of the manufacturer.
•This operator’s guide is not meant to supersede any controlling operating procedure
regarding the safe use of assisted ventilation.
•Follow all governing regulations regarding the disposal of any part of this medical device,
the handling of materials contaminated by body fluids, and shipment of the Li-ION
batteries.
Ventilator
•The Z Vent ventilator can operate from its internal battery or from an external power source.
When using external power, position the power cord to avoid accidental disconnect.
•The use of accessories and cables other than those sold by ZOLL may result in increased
emissions or decreased immunity of this device.
•Portable and mobile RF communication equipment may affect the performance of this
device. We describe the EMC performance for this device in Appendix A Specifications of
this guide.
•The ventilator may cause radio interference or may disrupt the operation of nearby
equipment. It may be necessary to take mitigation measures, such as re-orienting or
relocating of the device or shielding the location.
•Do not connect to an electrical outlet controlled by a wall switch or dimmer.
•The protection against defibrillator depends on the use of accessories (including Pulse
Oximeter) that are specified by ZOLL.
•Grounding:
•Do not under any circumstances remove the grounding conductor from the power
plug.
•Do not use extension cords or adapters of any type. The power cord and plug must
be intact and undamaged.
•If there is any doubt about the integrity of the protective earth conductor or power
supply, operate on internal battery power.
•As with all medical equipment, carefully route the patient circuit, patient cabling, and
external power cords to reduce the possibility of patient entanglement or strangulation.
The product design includes materials with phthalates in the pressure lines of
both the manifold design and patient circuit. Patient mask accessories used
with the device also are made with materials containing phthalates.
Phthalates are NOT present in the inspiratory line (Gas Hose) of the patient
circuit.

General Information
9650-002360-01 Rev. A ZOLL Z Vent Ventilator Operator’s Guide 1-11
•Do not use in MRI environment unless MRI marking is present.
•Do not operate the ventilator on a patient when the USB port is connected to any other
device (the USB port is only for servicing the ventilator).
•The ZOLL-supplied patient circuit’s labeling provides the resistance and compliance values
for the circuits under normal operating conditions. If added accessories are used
(e.g. HME, filters etc.), you should assure they do not degrade the performance of the
device.
Pulse Oximeter
•Do not use the pulse oximeter as an apnea monitor.
•A pulse oximeter should be considered an early warning device. As a trend towards patient
deoxygenation is indicated, blood samples should be analyzed by a laboratory co-oximeter
to completely understand the patient’s condition.
•Measurements: if the accuracy of any measurement does not seem reasonable, first check
the patient’s vital signs by alternate means and then check the pulse oximeter for proper
functioning.
Inaccurate measurements may be caused by:
•Incorrect sensor application or use.
•Significant levels of dysfunctional hemoglobin (e.g. carboxyhemoglobin or
methemoglobin).
•Intra-vascular dyes such as indocyanine green or methylene blue.
•Exposure to excessive illumination, such as surgical lamps (especially ones with a
xenon light source), bilirubin lamps, fluorescent lights, infrared heating lamps, or
direct sunlight (exposure to excessive illumination can be corrected by covering the
sensor with a dark or opaque material).
•Excessive patient movement.
•Venous pulsations.
•Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter,
or intravascular line.
•The pulse oximeter is defibrillator-proof. The pulse oximeter can be used during
defibrillation, but the readings may be inaccurate for a short time.
•Interfering Substances: carboxyhemoglobin may erroneously increase readings. The level of
increase is approximately equal to the amount of carboxyhemoglobin present. Dyes, or any
substance containing dyes, that change usual arterial pigmentation may cause erroneous
readings.
•Alarms: Check alarm limits each time the pulse oximeter is used to ensure that they are
appropriate for the patient being monitored.
•Loss of pulse signal can occur in any of the following situations:
•The sensor is too tight.
•Excessive illumination from light sources such as a surgical lamp, a bilirubin lamp,
or sunlight.
•A blood pressure cuff is inflated on the same extremity as the one with an SpO2
sensor attached.
•The patient has hypotension, severe vascoconstriction, severe anemia, or

•Sensors:
•Before use, carefully read the Masimo LNCS®sensor directions for use.
•Use only Masimo oximetry sensors for SpO2measurements. Other oxygen
transducers (sensors) may cause improper performance.
•Tissue damage can be caused by incorrect application or use of an LNCS sensor for
example, by wrapping the sensor too tightly. Inspect the sensor site as directed in
the sensor Directions for Use to ensure skin integrity and correct positioning and
adhesion of the sensor.
•Do not damage LNCS sensors. Do not use an LNCS sensor with exposed optical
components. Do not immerse the sensor in water, solvents, or cleaning solutions
(The sensors and connectors are not waterproof). Do not sterilize by irradiation,
steam, or ethylene oxide. See the cleaning instructions in the directions for reusable
Masimo LNCS sensors.
•Do not use damaged patient cables. Do not immerse the patient cables in water,
solvents, or cleaning solutions (the patient cables are not waterproof). Do not
sterilize by irradiation, steam, or ethylene oxide. See the cleaning instructions in
the directions for reusable Masimo patient cables.
•Do not use the pulse oximeter sensor during magnetic resonance imaging (MRI) scanning.
Inducing current could potentially cause burns. The pulse oximeter may affect the MRI
image and the MRI unit may affect the accuracy of the dosimetry measurements.
Batteries
•Only use the power supply provided with the device. Use of any other power supply could
cause damage or create a fire and/or destroy the battery and device.
•If you witness a battery or the battery compartment starting to balloon, swell up, smoke, or
feel excessively hot, turn off the device, disconnect external power, and observe it in a safe
place for approximately 15 minutes and send the device for service. Never puncture or
disassemble the battery packs or cells.
User Safety
•Electric shock hazard: Do not remove equipment covers. You may only perform
maintenance procedures specifically described in this manual. Refer all servicing to
ZOLL or a ZOLL-authorized service center.
•Possible explosion hazard if used in the presence of flammable anesthetics or other
flammable substances in combination with air, oxygen-enriched environments, or nitrous
oxide.
•This device is not intended for use in explosive atmospheres.
•Pins of connectors identified with the ESD warning symbol should not be touched. Always
use precautionary procedures with ESD-sensitive connections.
Patient Safety
•To ensure patient electrical isolation, connect only to other equipment with electronically
isolated circuits.
•Do not place the device or external power supply in any position that might cause it to fall
on the patient. Do not lift the device by the power cord, patient circuit, or pulse oximeter
patient cable.
•Never service the ventilator while in use with a patient.
