What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CM-1600Device
Healthy subjects undergoing a manual blood loss of up to 500mL followed by an infusion of 1 liter of normal saline will be connected to the CM-1600 device.

What is being measured
The primary outcome is the main question the study is designed to answer.
CM-1600 Ability to Detect Minor Blood Loss
The objective of this study is to determine if manual blood loss of up to 500mL of blood can be identified using the non-invasive Zynex CM-1600. This will be measured by determining the percent change in Relative Index (RI) before and after the Blood Draw. The RI is an investigational value which utilizes proprietary algorithms to combine the changes of multiple measured parameters (utilizing a weighted summation of percent change values) which are indicative of relative changes in fluid volume in adult patients into a single value. The RI is a unitless value with no set minimum or maximum, where 100 is a patient's baseline. Based on the nature of the RI itself, a direct interpretation of a positive or negative outcome cannot be derived from the absolute value, instead it could be used to monitor trending of a patient's parameters relative to their baseline.
Measured: Duration of Recovery Period following blood draw (10 minutes)
CM-1600 Ability to Detect Saline Reinfusion
The objective of this study is to determine if a saline reinfusion of 1000mL of normal saline can be identified using the non-invasive Zynex CM-1600. This will be measured by determining the percent change in Relative Index (RI) before and after the Saline Reinfusion. The RI is an investigational value which utilizes proprietary algorithms to combine the changes of multiple measured parameters (utilizing a weighted summation of percent change values) which are indicative of relative changes in fluid volume in adult patients into a single value. The RI is a unitless value with no set minimum or maximum, where 100 is a patient's baseline. Based on the nature of the RI itself, a direct interpretation of a positive or negative outcome cannot be derived from the absolute value, instead it could be used to monitor trending of a patient's parameters relative to their baseline.
Measured: Recovery period following saline reinfusion (10 minutes)
