Color chart for the detection of the amount of methemoglobin in the blood The diagnosis of methemoglobinemia is made with the typical symptoms, a suggestive history, low oxygen saturation on pulse oximetry measurements (SpO2) and these symptoms (cyanosis and hypoxia) failing to improve on oxygen treatment.
Once identified, the leak can often be repaired by an epidural blood patch, an injection of the patient's own blood at the site of the leak, a fibrin glue injection, or surgery. A spontaneous CSF leak is a rare condition, affecting at least one in 20,000 people and many more who go undiagnosed every year.
hemoconcentration (elevated hematocrit and hemoglobin readings, with hematocrit levels >49% in men and >43% in women, not because of an absolute increase in them but because of the leak of plasma); very low blood pressure (profound arterial hypotension, with systolic blood pressure levels <90 mm Hg);
Bruise colors vary from red, blue, or almost black, depending on the severity of broken capillaries or blood vessels within the bruise site. Broken venules or arterioles often result in a deep blue or dark red bruise, respectively. Darker colored bruises may result from a more severe bleeding from both blood vessels.
The National Highway Traffic Safety Administration is investigating reports of alleged engine failures in GM's 6.2-liter L87 V-8, an engine used in a wide variety of trucks and SUVs.
Cyanosis is the change of body tissue color to a bluish-purple hue, as a result of decrease in the amount of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. [1] Cyanosis is apparent usually in the body tissues covered with thin skin , including the mucous membranes , lips, nail beds , and ear lobes. [ 1 ]
The plane's two black boxes - key to finding out the cause of last month's crash on the jet - stopped recording about four minutes before the accident, posing a challenge to the ongoing investigation.
Ischemia or ischaemia is a restriction in blood supply to any tissue, muscle group, or organ of the body, causing a shortage of oxygen that is needed for cellular metabolism (to keep tissue alive). [3] [4] Ischemia is generally caused by problems with blood vessels, with resultant damage to or dysfunction of tissue i.e. hypoxia and ...
