Heliox is a breathing gas mixture of helium (He) and oxygen (O 2).It is used as a medical treatment for patients with difficulty breathing because this mixture generates less resistance than atmospheric air when passing through the airways of the lungs, and thus requires less effort by a patient to breathe in and out of the lungs.
Most of these gases are drugs, including oxygen. [2] Many other gases, collectively known as factitious airs, were explored for medicinal value in the late eighteenth century. In addition to oxygen, medical gases include nitric oxide (NO), and helium-O2 mixtures (Heliox). Careful considerations and close monitoring needed when medical gases are ...
Cancer vaccines can also divided into specific or universal cancer vaccine based on the types of cancer it is used for. Specific cancer vaccines are only used to treat a particular type of cancer while universal vaccine can be used to treat different types of cancer. [4]
In severe cases of the disease, the following signs and symptoms may be present: [8] Blood clots in the veins, which may cause thrombophlebitis; Disseminated intravascular coagulation, a disorder causing severe bleeding in many body organs; Jaundice, or yellowing of the eyes and skin; Low blood sugar; Pleural effusion
A cancer vaccine, or oncovaccine, is a vaccine that either treats existing cancer or prevents development of cancer. [1] Vaccines that treat existing cancer are known as therapeutic cancer vaccines or tumor antigen vaccines. Some of the vaccines are "autologous", being prepared from samples taken from the patient, and are specific to that patient.
An mRNA vaccine is injected into the body, where it enters cells and tells them to create antigens which are then recognised by the immune system and prepare it to fight the disease. Asked when ...
Symptoms of cancer metastasis depend on the location of the tumor. When cancer begins, it produces no symptoms. Signs and symptoms appear as the mass grows or ulcerates. The findings that result depend on cancer's type and location. Few symptoms are specific. Many frequently occur in individuals who have other conditions.
Hyperpolarized gas MRI, also known as hyperpolarized helium-3 MRI or HPHe-3 MRI, is a medical imaging technique that uses hyperpolarized gases to improve the sensitivity and spatial resolution of magnetic resonance imaging (MRI). This technique has many potential applications in medicine, including the imaging of the lungs and other areas of ...
