Instruction For Use PMH7000 Version 2
Revision 03 23 July 2019 Page 4 of 20
1. Introduction
1.1 Intended Use
The Humidifier Heater Base PMH7000 is intended to add moisture and to warm the breathing gasses through ET tubes,
Tracheostomy tubes or any NIV interface for any patient adult, paediatric or neonate who needs mechanical or positive
pressure ventilation.
1.2Features of the device
PMH7000 Humidifier base features a dual temperature servo control system, which regulates the temperature of the gas
delivered to the patient and the gas at the outlet of the humidifying chamber. It continuously monitors temperatures using a
platinum dual temperature probe. The Humidifier base warms and humidifies the gas through the humidifier chamber and
in addition a heated wire in the patient breathing circuit further controls and keeps the same gas warm. The operator is
allowed to set the temperature of the chamber outlet gas, which controls the gas humidity just before it is delivered to the
patient. Temperature is displayed on the front panel.
A dual heated wire adaptor lead (REF 5601000) is separately available for the PMH7000 Humidifier base, for use with a
dual heated wire system, a single adaptor lead (REF 5600000) is available when using a single heated wire system.
PMH7000 Humidifier base is equipped with alarms, which activate audible and visual indicators to alert the operator of
adverse conditions. Alarms are provided for high and low airway temperature, high and low chamber outlet temperature,
dual temperature probe disconnect or fault condition, heated wire fault connection, a light on the front panel identifies the
area of alarm.
Various safety monitoring functions are incorporated to detect and prevent the over-heated conditions which may affect the
patient conditions or damage the unit itself. For patient safety, alarm conditions continue for 10 minutes and the Humidifier
base turns off unless set levels are achieved or adjusted by the operator.
2. Safety Precautions
The information provided in this manual should be read and fully understood before using the PMH7000 Humidifier base.
The information applies to the Humidifier base as well as any optional equipment and accessories used with the device.
2.1Warnings, Cautions and Notes
In this manual, a WARNING describes the actions necessary to prevent injury or loss of life. A CAUTION describes the
actions to be taken to protect the equipment from being damaged. A NOTE contains precautions, procedures and actions.
The principal WARNING and CAUTION notices to be observed during use of the PMH7000 are included in this
section for emphasis.
WARNING ! FOR USE BY TRAINED PERSONNEL ONLY: The PMH7000 Humidifier base and accessories are
designed for use by trained medical personnel acting under physician’s orders. It is prohibited that anyone other than
qualified medical personnel use these Humidifier bases.
WARNING ! OBSERVE BEST PRACTICE: The instructions in this manual do not supersede established medical
procedures or staff preferences concerning patient care. “Best Practice” as determined by the medical community and/or
individual institutions is always to be observed.
WARNING ! SETTING-UP: Do not place the Humidifier base and the humidifying chamber higher than patient,
otherwise, condensed water droplets may enter the patient airway.
WARNING ! SETTING-UP: Do not fill the humidifying chamber above the maximum fill level. Droplets of water may
enter into the patient breathing system if the chamber is overfilled.
WARNING ! SETTING-UP: Do not fill the chamber with distilled water in excess of 30C.
WARNING ! SETTING-UP: Ensure that the water level in the chamber is correct before use. Failure to ensure correct
water level in the chamber at start-up could result in the under humidification of the patient (see chamber IFU for details).
WARNING ! SETTING-UP: Ensure that the dual temperature probes are inserted correctly into the breathing system
ports as shown in diagrams on pages 17. Failure to do so may result in gas delivery to the patient above 43C. Before
connecting to the patient, ensure the ventilator or gas delivery device is operating properly and check the flow rate and
pressure levels are functioning correctly.
WARNING ! OPERATION: Prior to the use of this Humidifier base, the user must be totally familiar with the use,
application and safety procedures associated with this device.
WARNING ! OPERATION: Periodic checks of the temperature must be made to ensure that the temperature of the gas
delivered to the patient is as set by trained medical personnel. Excessive heat delivered to the patient may cause harm to
the airways and/or other hazards to the patient.
