| Task Description: |
This project will include development and production of two (2) minimally invasive devices to measure and analyze episcleral venous pressure in human subjects. The devices will be capable of making measurements in subjects positioned in the seated, supine, and head-down tilt postures. The devices will be delivered to and evaluated by the Johnson Space Center Cardiovascular & Vision Lab. This prototype hardware and software to measure the venous pressure draining the eye, if successful, could be incorporated into ongoing Spaceflight Associated Neuro-ocular Syndrome (SANS) research. |
|
| Rationale for HRP Directed Research: |
This research is directed because NASA must define complete scientific activities in a short time and there is insufficient time to issue a solicitation. The device needs to be delivered in time to be evaluated as a tool for evaluating countermeasure effectiveness in the upcoming SANS Ground Analog Countermeasure Study at :envihab (FY 2020). Measurement of venous pressure draining the eye will be used as an objective measure of a countermeasure’s ability to reverse the headward fluid shift associated with strict head-down tilt bed rest. Tentative development schedule requires 8-12 months before delivery. Directed task is required in order to meet schedule. |
