Arterial pressure transducer

The incision is closed and a dressing is placed over the surgical site. The arterial and venous catheters are connected to pressure transducers for measurement of the central venous and arterial pressures. 

The arterial catheter is pressurized at 300 mmHg for the entire study to ensure patency. The resistance of the pressure transducer will determine the amount of fluid administered through the arterial catheter. 

Cardiac output can be measured using dye- or thermal-dilution techniques or by placement of an electromagnetic flow probe around the pulmonary artery. Insertion of a pressure transducer or fluid-filled catheter into the pulmonary artery and pulmonary vein allows for the calculation of pulmonary vascular resistance. The measurement of flow through the proximal aorta may also be useful but does not include coronary blood flow and as such is not equivalent to... 

Blood pressure is recorded through a cannula inserted into the left femoral artery and connected to a Statham pressure transducer (Statham P 23 DB). 

A Statham pressure transducer is placed into the right femoral artery for continuous measurement of blood pressure. Spontaneous respiration is maintained through a tracheal tube. 

The right femoral artery is also isolated and a pressure transducer is attached to monitor arterial pressure. 

The three sensing fibers are bonded together over their last 6 cm and then chemically sterilized, and are designed to reside within a standard 20-gauge (1-mm) radial artery catheter. The probe is thin enough to allow easy blood withdrawal and undistorted propagation of the arterial pressure signal to a pressure transducer. The PIM is clamped at the bedside and connected to the monitor located elsewhere. 

On a multi-trace photograph recorder, we recorded blood pressure in a femoral artery through a Statham transducer, any occurring vocalisation with a microphone, and blood mass pre sent in a well-defined brain area through radioactivity by me ans of a shielded NaJ-Tl scintillator connected to a rate me ...
