Participants 10-21 years can use the Merge. The VE to be used in this study is mobile based (Pixel with the Merge) and has active matrix LCDs with high pixel resolution, creating a bright, vibrant color and a quality image. The VR game is equipped with a head-tracking system, enabling the player to look around the virtual environment. In addition, there is the option to interact with the VR environment using a tap pad located on the side of the helmet. Therefore, the child will be receiving distraction via 3-D visual and auditory sensory, and tactile feedback, thus supplying a multi-sensory immersive experience. While wearing these glasses, the children only can see the HMD screen so that the immersion and presence will be increased. The VR glasses will be sanitized before every use so that the chance of infection will be minimized.

Participants 7-21 years can use the Oculus Go. The visual a bright, vibrant color and a quality image. The VR game is equipped with a head-tracking system, enabling the player to look around the virtual environment. In addition, there is the option to interact with the VR environment using a handheld remote. Therefore, the child will be receiving distraction via 3-D visual and auditory sensory, and tactile feedback, thus supplying a multi-sensory immersive experience.

The MS is a six-point scale indicating level of nausea from (1) no symptoms to (6) being sick The MS is completed before and after administration of the VR game to monitor for any signs of nausea. Instructions to the child are as follows: "This is a scale from one to six. One means that you feel fine and no different to how you normally feel. Two means that you feel a little bit different or funny but not sick in the tummy. Three means that you feel a little bit sick and four means that you feel more than a little bit sick but not really sick. Five means that you feel really sick, like you are going to throw up or vomit and six means that you are being sick or vomiting. I'm going to ask you every few minutes how you feel. I want you to tell me which number from one to six best describes how you feel at that time."

The Child Presence Questionnaire was developed out of a content analysis of the entire domain of adult presence items and selection and adaptation of appropriate items for assessing the child's sense of believability of their experience. This 16-item measure is verbally administered to children and asks them to respond according to a 3-point Likert-like format. Items assess the child's sense of involvement, realism, and transportation into the experience. Patients in the VR condition will complete the Child Presence Questionnaire post-procedure to assess level of VR immersion.

The child survey is 13-item, Likert-like survey to assess child estimates of pain reduction, fear reduction, decreased behavioral distress, and overall satisfaction; it mirrors the parent survey. There are two versions, one for each treatment condition. Two versions of the survey exist, to account for condition (VR vs. standard of care).

The parent survey is 16-item, Likert-like survey to assess parent estimates of pain reduction, fear reduction, decreased behavioral distress, and overall satisfaction. Two versions of the survey exist, to account for condition (VR vs. standard of care).

The healthcare provider survey is a 7-item Likert-like investigator-developed survey to assess their estimates of pain and anxiety management, cooperation, and satisfaction with the procedure. Healthcare providers are also invited to write comments about the use of VR (if applicable) during the IV placement procedure.

VAS anticipatory anxiety measure: The VAS anticipatory anxiety measure is a vertical VAS, anchored with 0 at the bottom indicating the least amount and 10 at the top indicating the greatest amount, in response to the instruction to rate "how nervous, afraid, or worried" they were about the upcoming task. The scale also has color cues, graded from yellow at the bottom to dark red at the top, as well as a neutral face at the bottom and a face showing a negative expression at the top. Prior research used the VAS to rate anticipatory anxiety and pain in children.

Revised is an updated version of the Wong-Baker Faces Pain Rating Scale depicting no pain as a neutral expression as compared with the smiling face of the original measure. The child is asked to point to the face cartoon that depicts how they are currently feeling because of their pain. Face measures are thought to measure pain intensity, and the Wong-Baker Faces measure has demonstrated good reliability and validity.

A faces scale to predict pediatric pain unpleasantness.
