Lower Body Negative Pressure (LBNP) Chambers

Technavance Logo_WHITE_edited.png

Lower Body Negative Pressure chambers are widely used to investigate hemodynamic responses and address military/aerospace-related research questions. By applying negative pressure to the lower body, blood is translocated from the central circulation to the periphery; reducing central blood volume in a manner analogous to acute hemorrhage, orthostatic stress, and acceleration.

Technavance LBNP chambers build on this well-established methodology by offering a flexible, purpose-built platform tailored to modern research needs. In addition to an economical entry-level model, we offer custom configurations including integrated beds, motorized tilt, a dedicated MRI-compatible design, and fully automated pressure control. Large capacity chambers capable of accommodating integrated ergometers are also available.​

Technavance's LBNP Chamber with Head-Up Tilt and Autoamted Pressure Control.

User-friendly control software, included with automated systems, delivers high accuracy and enables investigators to fully customize vacuum test protocols for precise, repeatable experimentation.

Technavance offers eight LBNP chamber models built on a common platform, with options that vary by chamber size, pressure control, and tilt capability to support a wide range of research applications.
