Geriatric oncology is a branch of medicine that is concerned with the diagnosis and treatment of cancer in the elderly, usually defined as aged 65 and older. This fairly young but increasingly important subspecialty incorporates the special needs of the elderly into the treatment of cancer.
Oxygen therapy, also referred to as supplemental oxygen, is the use of oxygen as medical treatment. [1] Supplemental oxygen can also refer to the use of oxygen enriched air at altitude. Acute indications for therapy include hypoxemia (low blood oxygen levels), carbon monoxide toxicity and cluster headache .
An oxygen tent can be used in either a hospital setting or outside a health-care facility, and can be recommended for short- or long-term therapy. Typically the tent is made of transparent plastic material. It can envelop the patient's bed with the end sections held in place by a mattress to ensure that the tent is airtight.
Participating in regular aerobic [11] and muscle-strengthening [20] physical activity both during and after cancer treatment may reduce cancer-related fatigue. Current physical activity guidelines recommend adults with cancer to engage in at least 150 minutes per week of moderate- intensity or 75 minutes per week of vigorous-intensity aerobic ...
Hypoxia can result from a failure at any stage in the delivery of oxygen to cells. This can include low partial pressures of oxygen in the breathing gas, problems with diffusion of oxygen in the lungs through the interface between air and blood, insufficient available hemoglobin, problems with blood flow to the end user tissue, problems with ...
Tumor stroma and extracellular matrix in hypoxia. Tumor hypoxia is the situation where tumor cells have been deprived of oxygen.As a tumor grows, it rapidly outgrows its blood supply, leaving portions of the tumor with regions where the oxygen concentration is significantly lower than in healthy tissues.

This measurement is often used under treatment with a heart lung machine (extracorporeal circulation), and can give the perfusionist an idea of how much flow the patient needs to stay healthy. Tissue oxygen saturation (StO 2) can be measured by near infrared spectroscopy. Although the measurements are still widely discussed, they give an idea ...
