Accuracy and clinical utility of an oxygen saturation catheter

Cardiovascular catheters and accessories: Ex vivo testing of ferromagnetism, heating, and artifacts associated with MRI

“…Cardiovascular catheters and accessories are indicated for use in critically ill or high-risk patients (1)(2)(3)(4)(5). MRI, angiography, and spectroscopy procedures may play an important role in the diagnostic evaluation of these patients.…”

“…CARDIOVASCULAR CATHETERS and accessories are indicated for use in the assessment and management of critically ill or high-risk patients, including those with acute heart failure, cardiogenic shock, severe hypovolemia, complex circulatory abnormalities, acute respiratory distress syndrome, pulmonary hypertension, certain types of arrhythmias, and various other medical emergencies (1)(2)(3)(4)(5). In these cases, cardiovascular catheters are used to measure intravascular pressures, intracardiac pressures, cardiac output, and oxyhemoglobin saturation (1)(2)(3)(4). Secondary indications include venous blood sampling and therapeutic infusion of solutions or medications (1)(2)(3)(4).…”

“…In these cases, cardiovascular catheters are used to measure intravascular pressures, intracardiac pressures, cardiac output, and oxyhemoglobin saturation (1)(2)(3)(4). Secondary indications include venous blood sampling and therapeutic infusion of solutions or medications (1)(2)(3)(4). In addition, some cardiovascular catheters are designed for temporary cardiac pacing and intra-atrial or intraventricular electrocardiographic monitoring (5).…”

Electrophysiologic and Hemodynamic Effects of Sodium Bicarbonate in a Canine Model of Severe Cocaine Intoxication

“…The fiberoptic catheter was also connected to a SO 2 =CO computer (Oximetrix) for continuous measurements of mixed venous blood oxygen saturation and measurement of cardiac output (CO) (18). Cardiac output was determined by thermodilution technique (19).…”
