Study to Investigate Blood Samples Drawn With the HemoIV System

The goal of this study is to compare blood drawn using a device called HemoIV to standard-of-care blood drawn from a vein in the arm or from an IV catheter. The HemoIV is a device that is attached to an IV line. This device allows for blood to be drawn while a patient is receiving IV fluids.

The main questions it aims to answer are:

* Will the HemoIV device allow blood to be drawn without having to stop IV fluids?
* Will the HemoIV device provide the same laboratory results as blood draws done by current standard practice?

Participants will:

* Receive standard medical procedures and/or treatment;
* Have a HemoIV device inserted into their IV line in one arm;
* Have an blood drawn twice from the HemoIV and from an IV line or needle stick from a vein in the other arm. The second blood draw will be done about 8-22 hours after the first blood draw;
* Have the device removed after the second blood draw;
* Receive a phone call about 8 days later to see how you are doing.

The HemoIV investigational device allows for continuous administration of intravenous fluids for blood draw sampling without exposing patients to additional needle sticks, stoppage of intravenous therapy, and potential exposure to bacteria that are inherent risks when performing blood draws using traditional phlebotomy methods. The purpose of this study is to demonstrate the safety and effectiveness of the HemoIV system.

Participants serve as their own control to compare blood measurement parameters. Blood measurements extracted from the participant will be used to compare the control blood sample(s) to the HemoIV blood sample(s). The contralateral arm to the placement of the HemoIV will be the control arm of the study. It is hypothesized that the HemoIV will provide blood samples within the equivalency margin, compared to standard practice (Venipuncture or Peripheral IV Catheter).

The main objectives are:

* To quantitatively measure and compare blood samples drawn with the HemoIV system during continuous intravenous infusion to blood samples from the contralateral arm to demonstrate safety and efficacy of the HemoIV system
* To quantitatively measure and compare the potential advantages of HemoIV to Venipuncture or Peripheral IV Catheter blood draws

Participant population will consist of adult patients admitted to the hospital for a medical condition in the emergency department, inpatient, or observation units and are requiring blood draws as well as intravenous fluids.

Participants will:

* Receive standard of care intravenous therapy via HemoIV inserted through an established peripheral IV catheter
* Have blood samples obtained twice over a 24 hour period from the HemoIV and from an IV line or standard venipuncture from the contralateral arm
* The second blood sampling will occur approximately 8-22 hours after the first blood sampling
* The HemoIV device will be removed one hour after the second blood sampling occurs
* Participants will be called 8 days later to assess for adverse events

Quality control (QC) procedures will be implemented beginning with the data entry system and data QC checks that will be run on the database will be generated. Any missing data or data anomalies will be communicated to the site(s) for clarification/resolution.
