one pass= 14000 ug of ozone at 70 gamma 14,000x 70=9,800,000 units 10 pass= 140000 ug of ozone at 70 gamma 140,000x 70=98,000,000 units portal vein 300 ml gas at 30 gamma 300 ml x 30 gamma=9000 ug dose 140000/9000=15.5 times equals 10 pass 300 ml x "1000 ug per ml" =300,000ug at 30 gamma ,,,300,000x30 = 9,000,000 units MAH (standard gravity method) using 200 mL of gas at 30–70 ug/mL into 200 mL of blood delivers 6000–14,000 ug of ozone (which could be affected by plastic collection bag absorption). Hyperbaric ozone single pass (generally 200 mL blood with 200 mL ozone gas at 70 ug/mL) delivers 14,000 ug ozone.
