“…Gardner developed a graph to allow users and clinical engineers to plot the damping factor and natural frequency and thereby determine if the response of the kit was sufficiently accurate for clinical use [6]. In order to address the challenges of acquiring the two parameters, Gardner further developed a smart, simplified version of the square wave test by employing the fast flush device present on the transducer unit to generate a step in the pressure in the kit, followed by the calculation of damping factor and natural frequency of the oscillations generated as a reaction on the step.…”

“…Proper positioning of the transducer establishes a reference point for pressure monitoring. 11 The correct reference position for arterial and venous pressure monitoring requires that the top of the transducer be in the same plane as the right atrium. This location is customarily considered to be at the midaxillary line and is often called the "phlebostatic axis" (Figure 3).…”

Many biological signals must be measured and interpreted accurately to titrate therapy properly during donor care. Although the technological aspects of intravascular pressure monitoring are usually delegated to bedside nursing colleagues, organ procurement coordinators should be familiar with those devices and methods. The equipment, supplies, and procedures used for arterial and central venous pressure monitoring are reviewed. Transducer leveling and zeroing plus maintenance of the hydraulic tubing system between the transducer and bedside monitor are especially important. These variables may greatly influence the accuracy of the displayed pressures and, therefore, must be considered during donor assessment as treatment is considered.

“…The physical characteristics required of systems designed to measure biological pressures have been reviewed extensively by Gardner and Hollingsworth. 59 Inflation of the balloon isolates a pulmonary vascular segment, and flow in that segment ceases ( fig. 2).…”

Since its introduction nearly 30 yr ago, the pulmonary artery catheter (PAC) has become part of everyday management in cardiology, anaesthesia and intensive care but remains controversial. 12 37 78 136 164 The apparent failure to demonstrate improvements in patient outcome 28 66 68 192 and the risks associated with its use 15 153 have long been criticized. 139 Failure to explore its full use and redundancy of the catheter after initial placement are additional concerns. More worrying is the incorrect interpretation of data 64 82 97 and consequent misdirection of therapy. Others are disturbed by a reliance on measurements rather than on clinical signs. 140 However, many argue that the PAC enhances bedside understanding of cardiorespiratory interactions, complements the interpretation of clinical signs and benefits management of haemodynamic disorders. 47 53 62 65 77 136 157 170 The first part of this article reviews the history, technical aspects and practical uses of pulmonary artery catheterization. The second part evaluates the clinical impact of the PAC on anaesthesia and intensive care medicine.
