Datex-Ohmeda's 7900 Anesthesia Ventilator is a microprocessor-controlled ventilator designed for use with patients ranging from small infants to challenging lung, neurological, or cardiac cases.
The ventilator is equipped with internal monitors for inspired oxygen, airway pressure, and exhaled volume. For superior performance, the 7900 provides two powerful modes of ventilation that control either the volume or pressure of inspired gases.
AIR worked with Datex-Ohmeda to ensure that the product was easy to operate despite its sophisticated ventilation regimes. Our development process included the parallel development of several design concepts, leading to the rapid prototyping and usability testing of the preferred concept.
Our biggest design challenge was to give users the sense of direct control provided by older models equipped with large rotary knobs while also assuring functional flexibility and room for future design modifications.
To combine control with flexibility, we equipped the ventilator with five softkeys used in conjunction with a control wheel. To change a parameter value, such as the respiration rate, users simply press the softkey that corresponds to "Rate," rotate the control wheel to adjust the value, and then press the control wheel or the softkey a second time. This approach is actually quite fast and prevents unintended changes to parameter values.
The usability test showed that anesthesiologists and nurse anesthetists quickly adapted to the ventilatorís new user interaction style, which has set the tone for other Datex-Ohmeda products.

"Whether it's a challenging ventilation case or a routine procedure, Datex-Ohmeda's 7900 Anesthesia Ventilator is easier to use in virtually every clinical situation. By minimizing ventilator complexity, the 7900 enables you (the care giver) to focus on your patient instead of dials and controls." Datex-Ohmeda's Product Brochure |
