Other names. Hypoxaemia. Blood with higher oxygen content appears bright red. Specialty. Pulmonology. Hypoxemia is an abnormally low level of oxygen in the blood. [ 1][ 2] More specifically, it is oxygen deficiency in arterial blood. [ 3] Hypoxemia has many causes, and often causes hypoxia as the blood is not supplying enough oxygen to the ...
Diabetic ketoacidosis ( DKA) is a potentially life-threatening complication of diabetes mellitus. [ 1] Signs and symptoms may include vomiting, abdominal pain, deep gasping breathing, increased urination, weakness, confusion and occasionally loss of consciousness. [ 1] A person's breath may develop a specific "fruity" smell. [ 1]
Neuroglycopenia. Neuroglycopenia is a shortage of glucose (glycopenia) in the brain, usually due to hypoglycemia. Glycopenia affects the function of neurons, and alters brain function and behavior. Prolonged or recurrent neuroglycopenia can result in loss of consciousness, damage to the brain, and eventual death. [ 1][ 2][ 3]
What is a good oxygen level? “Normal people who have working lungs, and all those steps are going well, their blood oxygen level will usually be 96-100 percent,” adds Dr. Uppal. A few notches ...
Hypoglycemia, also called low blood sugar, is a fall in blood sugar to levels below normal, typically below 70 mg/dL (3.9 mmol/L). [1] [3] Whipple's triad is used to properly identify hypoglycemic episodes. [2] It is defined as blood glucose below 70 mg/dL (3.9 mmol/L), symptoms associated with hypoglycemia, and resolution of symptoms when ...
The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal arterial blood oxygen saturation levels in humans are 96–100 percent. [1] If the level is below 90 percent, it is considered low and called hypoxemia. [2] Arterial blood oxygen levels below 80 percent may compromise organ function, such as ...
The use of fNIRS as a functional neuroimaging method relies on the principle of neuro-vascular coupling also known as the haemodynamic response or blood-oxygen-level dependent (BOLD) response. This principle also forms the core of fMRI techniques. Through neuro-vascular coupling, neuronal activity is linked to related changes in localized ...
Diabetic hypoglycemia. Diabetic hypoglycemia is a low blood glucose level occurring in a person with diabetes mellitus. It is one of the most common types of hypoglycemia seen in emergency departments and hospitals. According to the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP), and based on a sample examined ...
