Ventilator Evaluation Kit
An evaluation kit form Sensirion, Stafa, Switzerland, and Nicolay, Nagold, Germany, enables ventilator manufacturers to take proximal measurements of respiratory gas rates as well as ventilation pressure. A pressure sensor is physically integrated into the connector cap and on the software side in the evaluation electronics. Pressure measurements are taken and converted into an electrical signal directly at the patient’s side; the pressure signal is then sent to the ventilator electronically. The signal is transmitted through an existing cable used to measure respiratory gas flow values. The tube for tapping pressure is only a few centimeters long and runs to the cap on the flow sensor, where the pressure signal is converted into an electrical signal.
