TwinStream™ Multi Mode Respirator for tubeless jet laryngoscopy, jet bronchoscopy, jet tracheoscopy and all types of jet ventilation in the fields of surgery and intensive medicine.

TwinStream™ is the first microprocessor-driven Superimposed High-frequency Jet ventilation apparatus and sets an entirely new standard in the jet ventilation technique.

All displays for monitoring are explicit and clearly structured. The alarm limits can be defined by the operator and can be set rapidly. TwinStream™ is the only ventilation apparatus in the world which, on the one hand, offers the option of being used in combination with patented jet endoscopes and, on the other hand, permits measurement of inspiratory oxygen concentration (FiO2Aw) in the respiratory tract by the use of 3- and 4-lumen catheters. The inspiratory oxygen concentration limit (FiO2Aw) which is set within the respirator by the electronic mode, and in the “laser-safe mode” for laser surgery, is an essential safety factor of TwinStream™.

Twinstream™ consists of two separately or simultaneously operating ventilation units. In superimposed jet ventilation (SHFJV®), jet ventilation of normal frequency and high frequency is conducted simultaneously. In addition, Twinstream™ permits ventilation at two different pressure plateaus. The level of the pressure plateau as well as the duration of inspiration and expiration can be selected. Thus, oxygenation as well as CO2 elimination can be regulated efficiently.

While ordinary jet ventilators usually provide too low emission pressures and are frequently provided with only one ventilation frequency, TwinStream™ is equipped with two separate or simultaneously operating ventilation components. In superimposed high-frequency jet ventilation®, high-frequency jet ventilation and ventilation of normal frequency are conducted simultaneously. In addition, TwinStream™ permits ventilation at two different pressure levels. The level of the pressure plateau as well as the duration of inspiration and expiration can be selected by the operator. Thus, oxygenation and CO2 elimination can be regulated. Due to its enormous spectrum of applications it can be used in neonates and even in highly obese adults.
