Source: Sharon Bord, MD, Department of Emergency Medicine, The Johns Hopkins University School of Medicine, Maryland, USA When monitoring patients, it is important to obtain values that are accurate and reliable. Blood pressure monitoring is one of the essential vital signs, and for a majority of patients, measuring it utilizing non-invasive techniques provides accurate values. However, there are situations in which the blood pressure requires more exact, specific, and reliable measurements.

Source: Julianna Jung, MD, FACEP, Associate Professor of Emergency Medicine, The Johns Hopkins University School of Medicine, Maryland, USA For unstable patients requiring urgent administration of medications, fluids, or blood products, establishing vascular access quickly is essential. However, there are many factors that can complicate placement of a peripheral intravenous cannula (PIV), and it is extremely common for PIV attempts to fail. PIV placement may be technically challenging in small...

Source: Shreyas Narsipur, Mechanical and Aerospace Engineering, North Carolina State University, Raleigh, NC Fluid pressure is an important flow characteristic that is required to determine the aerodynamics of a system. One of the oldest and still existing pressure measurement systems is the manometer due to its accuracy and simplicity of operation. The manometer is generally a U-shaped glass tube that is partially filled with liquid, as shown in Figure 1. The U-tube manometer requires no...

A novel technique to record the pressures within the skull is described. The minimally invasive method uses a fibre-optic pressure sensing system to accurately measure intracranial pressure (ICP) in anaesthetized rats without causing significant brain trauma. The technique may be used in a wide range of experimental models.
FAQs
Effective coupling allows physiological activity or physical energy to reach the transducer with minimal signal loss. Poor contact can weaken the measured signal and introduce artifacts, which may reduce the reliability of an image, pressure reading, temperature measurement, or physiological recording. Clinicians therefore position the device to maintain stable contact with the relevant body surface or structure throughout assessment.
Alignment determines whether the transducer receives the intended signal efficiently. If its orientation does not correspond to the target structure or source, the resulting signal may become weaker, distorted, or more difficult to interpret. Careful orientation improves the representation of the selected clinical target and helps distinguish meaningful findings from changes caused by positioning rather than patient physiology.
Incorrect contact, poor orientation, and positioning away from the intended signal source can all contribute to interference, artifacts, or signal loss. These problems may obscure clinically relevant information or produce measurements that are difficult to compare. Attention to placement reduces avoidable variation and supports a clearer relationship between the recorded signal and the physiological event being assessed.
Repeated measurements are more meaningful when the device occupies a comparable position and orientation during each assessment. Consistency helps clinicians determine whether a change reflects the patient’s condition rather than altered coupling, alignment, or proximity to the target. This principle supports longitudinal monitoring, improves comparisons between readings, and reduces interpretation errors linked to variable placement.
A practical placement process includes identifying the intended signal source or target structure, positioning the device over the relevant area, establishing adequate contact, and orienting it appropriately. The clinician should then assess whether the resulting signal or measurement appears usable and adjust the position if interference, artifacts, or signal loss are evident. Consistent positioning supports repeatable assessment.
The placement goal depends on what clinicians need to measure. Imaging requires positioning and orientation that represent the target structure, whereas pressure measurement, temperature monitoring, and other physiological recordings require access to the relevant source and stable contact. Across these applications, placement remains important because it influences diagnostic quality, measurement reliability, and the ability to follow changes over time.
