Adaptability and Description

Compact design

GraphNet ts provides a clear and complete display of vital signs variables on a built-in 12-

inch LED screen. User-friendly and intuitive programming helps managing critical patients safely through:

  • User-friendly and intuitive programming.
  • Touch screen.
  • Rapid-access keys.
  • High visibility alarm indicator.

Comprehensive monitoring

Monitoring of vital signs variables such as mandatory and spontaneous minute ventilation, spontaneous frequency, exhalation time constant, leaks.

Built-in respiratory mechanics menu provides a vital tool for making correct information- based decision increasing the efficacy of treatment and guaranteeing patient safety.

Non-invasive ventilation

A ventilation mode with automatic leak compensation. Provides effective patient ventilation, while keeping the upper respiratory airways intact.

Reliable volume and leak monitoring through an interface that improves synchronization and patient comfort.

Intra-hospital transport mode

Allows transferring patients inside the medical facility without interrupting ventilation and monitoring.

Alternative air supply

In the case of absence or deficiency of the central air supply, an available medical grade air compressor is a viable alternative source of air supply. Optional accessory including 4-wheel cart.
