What Is the Effectiveness of the Diaphragm?
Here's the deal on diaphragm effectiveness: If you use your diaphragm perfectly every single time you have , it's 94% effective. But nobody's perfect, so in real life diaphragms are about 88% effective — that means about 12 out of 100 people who use a diaphragm will get pregnant each year. That's because people don't always follow ...

FUNDAMENTALS AND PRINCIPLES OF DIAPHRAGM METERS
Diaphragm meters are utilized to accurately measure the consumption of gas. They trace their roots to the wet-type positive displacement meter developed by Clegg in 1815. His design was improved by John Malam and Crosley. In 1825, the New York Gas Light Company utilized the wet drum meter for commercial use.

Gas exchange during separate diaphragm and intercostal ...
This suggests that diaphragm breathing is significantly more efficient than intercostal muscle breathing. However, despite markedly different patterns of inspiratory muscle engagement and resultant alterations in the distribution of ventilation, there are coincident alterations in the distribution of perfusion, resulting in normal gas exchange.

How do Diaphragm Compressors Work? | Sundyne
Diaphragm compressors move (and compress) gas using a set of three, flexible diaphragm membranes. Gas enters the compressor's process head from an external tank or process on its down-stroke. On the up-stroke, the diaphragms flex, reducing the area inside the chamber, pushing the gas out of the compressor (and on to the process/application).

Breathing | Boundless Biology
The process of inhalation occurs due to an increase in the lung volume (diaphragm contraction and chest wall expansion) which results in a decrease in lung pressure in comparison to the atmosphere; thus, air rushes in the airway. ... The flow of air is in the opposite direction from blood flow, which allows efficient gas exchange. This type of ...

Recently we developed a gas/liquid diaphragm cell for efficiently providing oxygen from the atmosphere, and the diaphragm cell was implemented to develop Air bio-battery (Arakawa et al., 2018). However, the generated power was not sufficient to drive devices with low power consumption, which typically require from a few to tens of mW.

Diaphragm Exercises Guide – Expand a Lung
Efficient gas exchange –Gas exchange takes place in the bottom third of our lungs. Which makes oxygenation more efficient when we activate our diaphragm. As mentioned before chest breathing can lead to chronic neck and back pain. Breathing with the diaphragm eases the muscle tension in our shoulders and neck allowing them to relax.

How Does the Diaphragm Help During Inhalation and Expiration?
The diaphragm adopts a curved shape when it is relaxed, and when someone inhales it flattens and allows the lungs to expand. During expiration it gradually curves again, allowing for expiration. The diaphragm is a naturally curved muscle that sits between the thoracic and abdominal cavities. When it is at rest, it is slightly tense.

US3917162A - Diaphragm valve for controlling supply of gas ...
Valve for controlling flow of gas to water heater comprises two chambers separated by a diaphragm. A first chamber has a gas inlet and a gas outlet leading to the burner of the heater. The outlet is controlled by the diaphragm position which is in turn dependent on the relative pressure in the chambers. A by-pass connects the two chambers, and the diaphragm position is therefore dependent on ...
