The concentration of O2 in body tissues is a balance between that supplied by the blood and the activity of cellular respiration, which utilizes oxygen.
The importance of understanding this process is illustrated by five Nobel Prizes awarded to scientists in the last century to:

Breast Cancer
Reason for IV Therapy: Chemotherapy for breast cancer can cause significant side effects such as nausea, vomiting, dehydration, and neutropenia (reduction in neutrophils). Intravenous administration of medications helps maintain fluid and electrolyte balance and prevents complications.
IV Therapy Includes:Antiemetic drugs, hydration (saline, glucose), electrolytes (potassium, magnesium), as well as liver and kidney protection.

Lung Cancer
Reason for IV Therapy:Chemotherapy for lung cancer is aggressive and often accompanied by severe toxic effects. IV therapy helps reduce the burden on organs, improve toxin elimination, and prevent side effects such as vomiting and dehydration.
IV Therapy Includes: Hydration, kidney and liver protection drugs (e.g., Mesna and Heptral), antiemetics, and electrolytes.

Stomach and Intestinal Cancer
Reason for IV Therapy: These cancers can cause serious digestive and electrolyte imbalances, requiring infusion support. Additionally, chemotherapy can severely affect the gastrointestinal (GI) tract, causing nausea, diarrhea, and dehydration.
IV Therapy Includes: Hydration solutions, antiemetics (Ondansetron, Dexamethasone), as well as electrolytes and drugs to protect the stomach lining.

Ovarian Cancer
Reason for IV Therapy: Chemotherapy for ovarian cancer can lead to severe intoxication and impaired kidney function. IV therapy is used to restore fluid balance, prevent vomiting, and neutropenia.
IV Therapy Includes: Saline, electrolytes, antiemetic drugs, hepatoprotectors, and nephroprotectors.

Pancreatic Cancer
Reason for IV Therapy: Due to the high toxicity of chemotherapy drugs and damage to pancreatic cells, constant fluid replenishment and support for the liver and kidneys are necessary. IV therapy helps reduce toxic effects on the body.
IV Therapy Includes:Glucose, saline, antiemetics, organ protection drugs (Heptral, Mesna), and electrolyte balance support.

Prostate Cancer
Reason for IV Therapy: Chemotherapy for this type of cancer can cause complications such as nausea, dehydration, and neutropenia. IV therapy helps maintain the body's normal condition during treatment.
IV Therapy Includes: Antiemetic drugs, electrolytes, saline and glucose, as well as liver protection drugs.

Leukemia and Lymphoma (Hematologic Oncology)
Reason for IV Therapy: Chemotherapy for leukemia and lymphoma is particularly toxic and requires body support to prevent serious complications such as sepsis, severe anemia, and neutropenia.
IV Therapy Includes: Hydration, antiemetics, electrolytes, liver and kidney support drugs (e.g., Allopurinol for hyperuricemia prevention), antibiotics, and antifungal agents in case of infections.

Bladder Cancer
Reason for IV Therapy:Some chemotherapy drugs for bladder cancer (e.g., cyclophosphamide) can cause severe irritation of the bladder lining and nephrotoxicity, requiring intravenous protection.
IV Therapy Includes: Mesna for bladder protection, hydration, electrolytes, and antiemetic drugs.

Liver Cancer
Reason for IV Therapy: The liver is affected by toxins during chemotherapy, so medications for its protection are prescribed. Hydration is also necessary to help the liver cope with the load.
IV Therapy Includes: Hepatoprotectors (Heptral), hydration solutions, antiemetics, and electrolytes.

Kidney Cancer
Reason for IV Therapy: Chemotherapy can impair kidney function, requiring protection and adequate fluid replenishment.
IV Therapy Includes: Saline, electrolytes, kidney protection drugs (e.g., Allopurinol), and antiemetics.
