1.3 General Warnings & Cautions
WARNING
DHAMAN-III ventilator is a critical care medical equipment and must be operated by
a trained medical or healthcare worker/professionals in accordance to the
guidelines given in this booklet.
Always perform Functional Check prior to connecting the ventilator to a patient.
To ensure that the internal battery remains functional, fully recharge the battery at
least every 2 months when the ventilator is not in use.
Always keep alternative means of ventilation ready for use in case of equipment
failure in order to avoid possibility of patient death or serious deterioration of health.
Breathing system filters and heat & moisture exchanger require frequent
replacements to prevent build-up of resistance and blockage.
In case of the following, stop the use of ventilator and contact service assistant:
If abnormal screen shows up
If an alarm cannot be settled
If the device creates any abnormal sound
If the device is operating abnormally or shows unexpected failure
The ventilator must always be kept in the vertical position during use.
If the ventilator is connected to a patient,
Carefully monitor the patient.
Prepare/keep a reserve ventilator for back-up, should the device fail
unexpectedly.
Do not raise or separate the expiratory part.
Always check the setting and measurement values displayed on the screen.
Do not cover the ventilator in any way. This will lead to errors in its functions.
Do not block or obstruct the vent (brass mesh filter for mixer damping - sintered
disc) on right side of ventilator as it may affect oxygen concentration delivery.
Continuously check the Expiratory part of the ventilator for contamination.
Do not use the system with worn or frayed hoses or hoses that have been
contaminated, or that may have come in contact / contaminated by combustible
materials such as grease or oil.
Oxygen enriched gas is extremely flammable: if you detect a burning odour, then
disconnect the oxygen supply to the ventilator and turn off the system.
The gases used in the system must be free from particles.
The system is not intended to be used with any anaesthetic agent.
NOTE
This Symbol represents “NOTE”
This symbol is associated with issues you should note regarding the surrounding
environment or additional references to the descriptions in this manual. It does not
pertain to possible damages to the product or the patient.

CAUTION
Always use a humidifier or disposable humidifies for prevention of dry lung tissues.
When separating or transporting the ventilator or its parts, refer to User Manual or
contact us for any kind of assistance. Always take care while transporting the
ventilator against damages, contamination and missing of loose parts.
Be careful when handling tube, connector, and patient tube parts. Use of support
arm can reduce the weight of tube exerted on the patient and improve the comfort
for the patient.
Do not remove or renovate any part of the ventilator.
Under no circumstances should you attempt to service or repair the device
yourself, if you do so our company is not responsible for safe operation of
ventilator.
While using nebulisation breathing system, filters and heat and moisture
exchangers could require more frequent replacements to prevent build-up of
resistance and blockage.
Please turn off the power to recharge the battery when it is not used.
DHAMAN-III ventilator system is a product conforming to Class II.
