## Indications for use
Biosensors flow-directed Thermodilution catheters are designed for use in critical care patients to measure cardiac output, right atrium, pulmonary artery and pulmonary capillary wedge pressures; continuously monitor pulmonary artery temperature, sample blood, intravenously administer drugs and solution and measure cardiac output via the cardiac output computers which interface with 14 kilo-ohms catheters. Different models are available for use in pediatric and adult patients. The tips of the catheters are mounted with a latex balloon which, when inflated, protects the heart tissues from the product's tips during insertion; utilizes blood flow to direct the catheter tip through the right ventricle into the pulmonary artery.
