What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Peripheral IV Access Success Rate | Peripheral IV access success rate is defined as the number of subjects who had successful peripheral intravenous cannulation on the first attempt. An attempt was defined as a needle penetrating the surface of the subject's skin. Successful access was defined as good flow through an IV catheter with a saline flush and without subcutaneous fluid collection. | baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Total Number of Peripheral IV Access Attempts | The total number of peripheral IV access attempts for each subject., up to a maximum of four attempts. An attempt is defined as a needle penetrating the subject's skin surface. | baseline | 
| Total Number of Distinct Providers That Attempted IV Access | Total number of individual medical providers that attempt to access IV for each subject. An attempt is defined as a needle penetrating the surface of the subject's skin. Access was defined as good flow through an IV catheter with a saline flush and without subcutaneous fluid collection. | baseline | 
| Rate of Rescue Techniques Used | The number of subjects requiring one or more rescue techniques to access peripheral IV. These techniques include ultrasound guided peripheral IV access, central venous access, venous cut-down, interosseous access, and/or change in treatment plan due to unsuccessful access. | baseline |
