Media #3: Carbon Dioxide (CO2) will be injected with large volume hand injection syringe as per the usual protocol. This be done with particular attention to avoid air in the closed system. In addition to supine, there is also an option that the patient's distal limb may be elevated to improve the flow of CO2 during injection. The surgeon will also wait at least 2 minutes between each CO2 injection to allow any potentially trapped CO2 to dissolve. A range of 20-60 ml will be used with each hand injection based on the data from the initial 5-10 pilot patients. Intervention protocol will be followed per Cross-Reference Intervention.
