Task Book: Entry Unavailable
Principal Investigator: Ebert, Doug

Short Title: Impedance Threshold Countermeasure

Responsible HRP Element: Human Health Countermeasures

Collaborating Org(s):

Funding Status: Completed - Task completed and produced a deliverable

Procurement Mechanism(s):

Solicited

Aims:

Using a supine and head-down tilt model, this investigation will:

1. Determine if an impedance threshold device can reduce venous sinus congestion in the head and neck.

*Primary outcome measures are the IJV cross sectional area, TCD, tissue thickness, and IJV, carotid artery, and SOV Doppler.

2. Determine if an impedance threshold device can reduce indicators of elevated intracranial pressure

*Primary outcome measures are ONSD, OCT, CCFP, IOP

This task might also inform SANS3 (tools) and SANS12 (ground based countermeasures).

Category: Countermeasure
Subcategory: Prototype Hardware or Software

Description:

The primary deliverable for this investigation will be a report that details the effects of an ITD on healthy volunteers in a supine and HDT model. Recommendations will be made regarding the potential usefulness of ITDs as a SANS countermeasure and the next steps in countermeasure development, if warranted.
