Are there disposable parts that need to be discarded after every patient?

Does the machine have an automatic pre-operational check system?

Alarm limits and management

Does the process involve manual maneuvers?

In case of a complete automatic test, does the machine have a short test for emergencies?

Can the machine adjust alarm limits, and are they patient-type-specific?

Automatic Parameters Adjustment

Does the machine propose or change alarm limits based on patient settings?

Is there an alarm limit auto-adjustment button?

Does the machine have different settable ranges for different patient types? (Adult, Paediatric and Neonatal)

Do the parameters have dynamic safety ranges according to the entered IBW of the patient?

Core technology

Does the selectable range depend upon another interdependent parameter like rate and Inspiratory time are interdependent on each other?

Does the selectable range have any automatic changes or adaptability according to set alarm limits?

What technology does the ventilator employ, and how does it affect noise levels and precision?

Does the machine require an additional air supply or a compressor?

Can the machine function entirely on battery backup?

Technical Specification

does the machine support the intrahospital transfer of patients?

What is the lifetime and warranty on the Blower?

Tidal volume range

Pressure Range

Respiratory Range

Leakage compensation

Maximum achievable flow


User Interface

Touch or non-Touch

Gesture control for easy manoeuvrability

Data Storage

Does the machine have configurable screens, parameters, and other elements, or it is fixed?

Is the machine configurable for a suitable screen layout?

Does the machine store patient monitoring data?

Does it also store the events and other important things like changes in settings?


What is the storage capacity?

Can this data be exported in an easy way?

Does the machine have only basic modes or advanced modes like Volume guarantee pressure modes, Inverse ratio ventilation, etc?

Clinical Tools

Does the machine have any auto ventilation mode?

Does the machine support oxygen therapy and Non-invasive ventilation modes?

Does the machine have inbuilt Spirometry?

Does the machine measure crucial parameters like Intrinsic PEEP, Compliance, and Resistance of the patient?

Does the machine have a tool to help in Weaning?

Lifetime cost and maintenance

Does the machine have a tool to assist the doctor in deciding the optimum PEEP level?

What is the Lifetime cost of the machine?


Does it cover all the accessories required to maintain the sterilization protocol?

What is the overall Lifetime cost of the machine?

What is the standard warranty provided with the machine?

Are there any parts of the machine not covered by this warranty?

Maintenance Cost
