capacity

[kə′pas·əd·ē]
(analytical chemistry)
In chromatography, a measurement used in ion-exchange systems to express the adsorption ability of the ion-exchange materials.
(computer science)
(electricity)
(science and technology)
Volume, especially in reference to merchandise or containers thereof.

capacity

2. The volume contained in a vessel.
3. The maximum or minimum water flow obtainable under given conditions (e.g., specified conditions of pressure, temperature, and velocity).

capacity

As it pertains to airports, it is the ability of an airport to handle a given volume of traffic. It is a limit that cannot be exceeded without incurring an operational penalty.

capacity

(communications)
The maximum possible data transfer rate of a communications channel under ideal conditions. The total capacity of a channel may be shared between several independent data streams using some kind of multiplexing, in which case, each stream's data rate may be limited to a fixed fraction of the total capacity.

capacity

With regard to computer and information systems, capacity refers to the storage and transaction processing capability of computer systems, the network and/or the datacenter. See capacity on demand and storage capacity.

The limit of five tests is somewhat arbitrary but tries to account for the fact that the test itself may alter diffusing capacity.
The most current standards are the 1995 ATS standards (Single-breath carbon monoxide diffusing capacity (Transfer Factor): Recommendations for a standard technique--1995 Update.
1]) was 20% or less of the predicted value and those with severe loss of lung surface area as measured by a diffusing capacity of less than 20% of predicted value or CT scan results indicating a homogeneous pattern of alveolar destruction throughout the lungs.
By the time of enrollment, many people exhibited considerably impaired lung function, with a median forced vital capacity (FVC, or the amount of air that can be exhaled after maximum inhalation) of 72 percent (61 to 81 percent) predicted and diffusing capacity of carbon monoxide (DLCO, or the measure of the lungs' ability to transfer oxygen to red blood cells) of 39 percent (34 to 48 percent) predicted.
1) showed no significant correlations between functional status and lung involvement parameters such as pulmonary arterial hypertension, dyspnea, Carbon Monoxide Diffusing Capacity and FVC, and concluded that the HAQ-DI is of no value as an outcome measurement in SSc patients.

A variety of other tests are often helpful in narrowing the differential diagnosis--for example, chest imaging, blood eosinophil measurement, allergy testing, bronchial challenges, diffusing capacity of the lung for carbon monoxide, lung volumes, and elasticity.
1) Most patients demonstrate impaired gas exchange, as evidenced by low oxygen-haemoglobin saturation at rest or on exercise; hypoxaemia on arterial blood gas sampling; or impaired diffusing capacity (DLCO).
12,13) Miyazaki et al (14) described risk factors for exacerbations and concluded that low diffusing capacity of the lung for carbon dioxide, low mean total lung capacity, low lymphocyte levels in bronchoalveolar lavage fluid, and a UIP-like pattern on histology were risk factors for acute exacerbation.
Of all the tests in the pulmonary function laboratory, the single breath diffusing capacity using carbon monoxide, DLCO, is the test most prone to inter and intra laboratory error and variation due to both faulty technologist technique and to general difficulties and complexities in measurement.
1] percent predicted, residual volume (RV)/total lung capacity (TLC) ratio, and the single-breath diffusing capacity of the lung for carbon monoxide (DLCO) percent predicted [15].
Patients with cancer had a relatively reduced diffusing capacity of the lung for carbon monoxide, reduced skeletal muscle strength, and lower ventilatory thresholds during exercise compared with HC (P < 0.
