The Defense Health Agency Contracting Activity, 808 Schreider Street, Fort Detrick, MD 21702, is seeking to understand the capabilities of potential qualified Contractors who can provide the supplies and/or services for the following:

Minimum Essential Characteristics: Cardiac Monitoring Platform

The United States Army Institute of Surgical Research (USAISR) seeks a device that can monitor cardiac output (CO) and derive hemodynamic parameters in a hospital setting. The USAISR requires a CO monitoring device that utilizes a Swan-Ganz catheter to monitor hemodynamic parameters. The device’s proprietary coded output must be compatible with USAISR’s unique internal data logging systems. This is required to maintain historic and current protocol data continuity and workflow. Inability to meet these requirements will inhibit comparisons of current and future studies to USAISR historical data resulting in loss of data, and efforts.

The CO Monitoring Platform shall have the following specifications:

1. Ability to measure the following: mixed venous oxygen saturation (SvO2), CO, stroke volume, systemic vascular resistance, right ventricular ejection fraction, right ventricular end diastolic volume, pulmonary artery pressure, and pulmonary artery occlusion pressure.
2. Utilization of the Edwards Lifesciences 7.5 FR Swan-Ganz CCOmbo V set or a Swan-Ganz of equal functionality and performance that provides continuous monitoring of SvO2 and measures continuous calculation of cardiac output by using thermodilution principles.
3. Equipment dimensions equal to or smaller than 342 x 388 x 208 mm (height x width x depth)

       3. At least three (3) USB ports: 2 x USB 3.0; 1 x USB 2.0
       4. At least one (1) RJ-45 ethernet port
       5. At least one (1) HDMI port
    2.  Heart Rate average display
       1. Response time: 40 seconds for step increase from 80 to 120 beats per minute (BPM), 29 seconds for step decrease from 80 to 40 BPM.
       2. CO monitoring on: Averaging time: Time between CO measurements (3 to 21 minutes); Update rate: Approximately 1 minute; Response time: 175 seconds for step increase from 80 to 120 BPM, 176 seconds for step decrease from 80 to 40 BPM.
    3. Electrical
