But in the same time we don't know what was the presure in carotid artery? Was it normal to?cheerleader wrote:Normal internal jugular pressure is measured in cm of H2O. Normal internal jugular venous pressure is 5-9 cm H20. It can be as low as 2 cm H2O and still "normal."

As you can see from Dr. Zamboni's study, the pressure pre-angioplasty is the IJVs he treated was up around 14. That is NOT normal. It is too high.
Dr. Zamboni uses the exact same venous measurements that are taken in Budd Chiari disease, a disease of venous congestion of the liver due to hepatic vein occlusion...this is how venous pressure is measured pre and post angioplasty---in cm of H2O
http://ats.ctsnetjournals.org/cgi/conte ... 711#TABLE2All three hepatic veins were reopened in 23 patients (Table 2). The average pressure in the IVC was 25.1 cm H2O preoperatively and 11.8 cm H2O at the time of discharge.
What Dr. Zamboni found was a significant change in internal jugular and azygos vein pressure after angioplasty. THis cannot be denied. This is the way venous pressure is measured. period.

As you can see from diagram on previous page, from Dr. Zamboni's study, the pressure post-angioplasty in the IJVs he treated was up around 12.5 (in cm of H2O). By in Your/Zamboni standards, that is NOT normal. It is too high too ....You/Zamboni said normal is 5-9 (in cm of H2O). Still abnormal, angioplasty can't fix it.... is this pocedure useless??
