ConchaTherm Neptune Performance Characteristics:

Patient Airway Temperature Ranges (Adjustable):
Invasive Mode
Non-Invasive Mode
Temperature Display:
High-Temperature Alarm Limit: 41.0°C typical
Tracking Alarm: ± 2.0°C of the selected airway temperature, after the set temperature has been
reached.
Warm-up time: (Warm up is defined as patient temperature within 2°C of set point)
Heated-Wire
Non-Heated Wire
Recommended Flow Rates*:
Adult (22mm Circuits)
Adult (22mm Circuits)
Pediatric (15mm Circuits)
Pediatric (15mm Circuits)
Infant/Neonatal (10mm Circuits)
Infant/Neonatal (10mm Circuits)
Continuous Flow Oxygen:
*The Invasive Mode of the Concha Neptune was designed to provide 100% RH , as evidenced by moisture con-
densation, or "rainout" in the circuit at the recommended flow rates over the settable proximal airway tempera-
ture settings at zero gradient. In some cases, the use of positive gradient settings "
the recommended ranges may result in increased warm-up times or lower than recommended humidity outputs.
Additionally, some environmental conditions, such as warm ventilator outlet gas temperatures and/or high ambi-
ent temperatures, may require the use of the negative gradient setting "
moisture droplets in the circuit.
Humidity Output:
Invasive Mode > 33 mg H
gradient at the recommended Flow Rates listed above.
• Use of Positive or "Sun" gradient settings in some conditions can result in
humidity outputs at the patient of less than 33mg H
inspect for condensation droplets in the inspiratory circuit after one hour of
operation, and periodically thereafter.
Non-Invasive Mode > 10 mg/L at 32º C proximal airway temperatures when set at zero
gradient at the recommended Flow Rates listed above.
• This mode should only be used when the patient airways ARE NOT
bypassed.
