Motor Units

62.0K
A motor unit consists of two main components: a single efferent motor neuron (i.e., a neuron that carries impulses away from the central nervous system) and all of the muscle fibers it innervates. The motor neuron may innervate multiple muscle fibers, which are single cells, but only one motor neuron innervates a single muscle fiber.

Measurement: Standard Units

Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

Measurement: Derived Units

The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units.

Sound Intensity00:58

Sound Intensity

4.9K
The loudness of a sound source is related to how energetically the source is vibrating, consequently making the molecules of the propagation medium vibrate. To measure the loudness of a source, the physical quantity of interest is the intensity. This is defined as the energy emitted per unit of time per unit of area perpendicular to the sound wave's propagation direction. Since the total energy is greater if the source vibrates for a longer duration and over a larger area, dividing the...

Units of Measurement

5.3K
Mechanical engineering is one of the oldest branches of engineering. It deals with designing, analyzing, and manufacturing machines and mechanical systems. To ensure precise and accurate calculations, units of measurement are used. They provide a standard system for expressing and comparing physical quantities.
There are various well-known historical measurement systems, such as the Babylonian system, the Roman system, the Egyptian system, the Olympian system, the British system, and the Indus...

International System of Units01:29

International System of Units

5.2K
The International System of Units, known as the SI system, is a universally accepted measurement system recognized and used worldwide. The SI system is based on a set of three base units considered absolute, and their values do not change with location. These base units are meters, kilograms, and seconds.
Prefixes are used to define both larger and smaller quantities in the SI system. For example, milli, micro, and nano define smaller quantities, while kilo, mega, and giga are used to define...

Summary

National intensive care unit (ICU) consent practices vary widely. A universal consent protocol showed high acceptance in one institution, though adoption differed by patient demographics, highlighting a need for standardized consent procedures.

Area of Science:

  • Critical Care Medicine
  • Medical Ethics
  • Health Services Research

Background:

  • Obtaining informed consent for procedures in intensive care units (ICUs) is complex.
  • Practices for consent vary significantly across academic medical centers.
  • Standardized consent processes may improve patient care and adherence.

Purpose of the Study:

  • To assess national practices for obtaining consent for routine bedside procedures in academic adult ICUs.
  • To determine universal consent rates based on patient demographics within a specific institutional setting.

Main Methods:

  • A 10-question survey was distributed to U.S. surgical and pulmonary critical care program directors to evaluate consent practices.
  • A universal consent protocol was implemented and studied in an academic county hospital's ICUs.

Main Results:

  • Thirty-seven percent of program directors responded to the survey, revealing consent rates ranging from 35% to 97% by procedure.
  • Medical ICUs obtained consent more frequently than Surgical ICUs for central line and pulmonary artery catheter placement.
  • At the study institution, 90% of patients or proxies signed universal consent, with insured patients being more likely to provide full consent.

Conclusions:

  • Significant national variation exists in ICU consent practices, with a recognized interest in broader adoption of universal consent protocols.
  • Universal consent adoption was influenced by patient demographics, indicating potential disparities.
  • The universal consent protocol was well-received and widely accepted within the studied institution.
