Frequently asked questions
Does this unit provide stable anesthesia output?
Yes. The GE Tec 4 features advanced temperature and flow compensation. This engineering ensures that the output remains constant, reliable, and precise even during extended procedures or temperature fluctuations.
Is the operation simple for clinicians?
Absolutely. It is designed for straightforward use, featuring a single control dial with a clear concentration scale. This allows for quick, consistent, and intuitive adjustments during anesthesia delivery.
How does the safety interlock system work?
The integrated safety interlock is a critical feature that prevents the accidental activation of the unit. It also ensures secure integration with your anesthesia machine and prevents the simultaneous use of multiple vaporizers, minimizing risk in a clinical setting.
What is the agent capacity for this unit?
The GE Tec 4 offers two capacity metrics based on the wick state:
- Dry Wick: 135 cc
- Wet Wick: 100 cc
Can this unit operate across a wide flow range?
Yes, this vaporizer is highly versatile and supports a flow range of 0.25 to 15 LPM, making it suitable for a variety of continuous-flow anesthesia techniques.
Is this model reliable for daily clinical use?
As a certified refurbished unit, this vaporizer undergoes rigorous professional testing to ensure it meets high performance standards, providing a cost-effective and dependable solution for professional clinical environments.
Does it compensate for cooling effects during vaporization?
Yes. The unit is constructed with robust internal mechanics specifically designed to compensate for the cooling effect caused by the latent heat of vaporization, which maintains the desired agent concentration level with high precision.
Are the concentration adjustments precise?
Yes, the adjustment increments are calibrated for clinical accuracy:
- 0.25 increments for the 0.25 to 0.5 range
- 0.5 increments for the 0.5 to 5 range
Is this unit compatible with any anesthesia machine?
The Tec 4 Selectatec is designed to integrate securely with standard anesthesia delivery systems via its specialized mounting interface, ensuring it remains stable and functional as part of your existing setup.
What temperature range can it operate in?
The device is engineered to maintain high performance within an ambient temperature range of 18 to 35 °C.
