This proposed study aims to fill this gap by investigating whether needle tip movement during catheter advancement is affected by whether the individual performing the insertion pushes the catheter off the needle themselves or if it is done by another person.

Participant arrives at the simulation setting. Participant undergoes orientation and consent. This includes orientation to study procedure and equipment, explanation of catheter advancement techniques, and informed consent process. Following consent, participant fills out Participant Questionnaire. Total time required: Approximately 10 minutes.

Participant performs IV catheter insertion using 3 techniques: 1 (Self-advancement single hand), technique 2 (Self-advancement both hands), and technique 3 (second person assisted) in randomized order. Total time required: Approximately 5 minutes. Participant completes Participant Questionnaire. Participant's participation is concluded.

In this study, the observation to be carried out is the total distance of needle tip movement while performing the initial intravenous catheter advancement off of the needle using three different catheter advancement techniques including: Self-advancement with one hand; Self-advancement with two hands; Catheter advancement by another individual.

Inclusion Criteria:

1. 18 years of age or older
2. Willing to consent to the study
3. has some experience placing IV catheters

Exclusion Criteria:

1. Subject refuses to consent
2. Younger than 18 years of age
3. No experience inserting IV catheters

Participants for this study are Anesthesiology healthcare professionals/providers who perform IV catheter placement
