	Dead space - Wikipedia, the free encyclopedia
		In physiology, dead space is air that is inhaled by the body in breathing, but does not partake in gas exchange.
		Anatomical dead space is the gas in the conducting areas of the respiratory system, such as the mouth and trachea, where the air doesn't come to the alveoli of the lungs.
		Anatomic dead space is the volume of the conducting airways.

	Dead Space (Site not responding. Last check: 2007-10-12)
		Dead space is the portion of each tidal volume that does not take part in gas exchange.
		Anatomic dead space is the total volume of the conducting airways from the nose or mouth down to the level of the terminal bronchioles, and is about 150 ml on the average in humans.
		Physiologic dead space includes all the non-respiratory parts of the bronchial tree included in anatomic dead space, but also factors in alveoli which are well-ventilated but poorly perfused and are therefore less efficient at exchanging gas with the blood.

		Not all the air we breath in is able to be used for the exchange of oxygen and carbon dioxide.
		Anatomical dead space - the gas in the conducting areas of the respiratory system, such as the mouth and trachea, where the air doesn't come to the alveoli of the lungs.
		Alveolar dead space - the area in the alveoli that does get air to be exchanged, but there is not enough blood flowing through the capillaries for exchange to be effective.

	Dead Air Space - Wikipedia, the free encyclopedia
		Dead Air Space is a blog kept by members of the British band Radiohead on their website.
		The band prefer this method of communication with their dedicated fan base over the more traditional route where the press act as the middle man. This way, there is no skewed view as to what any member may be trying to get across.
		In addition to Dead Air Space being a regular place for the band to inform fans of the progress of the 7th album, Thom regularly uses it to air his views on many subjects, such as the environment and the government.

		It acts as an allegorical space that reflects and refracts the several manners and degrees in which the conquest of the West is rendered as a vicious brutality.
		Dead Man critically rejects Leone’s and Peckinpah’s violent hyper formalism and renders the cinematic visions of the vicious gun-mediated confrontation of the western as a symptomatic surface under which occurred the brutal slaughter of natives and the selfish exploitation of the Western land for profiteering purposes.
		Dead Man takes the “allegorical open form” that Jarmusch defines to stamp a counter-ideology that locates violent confrontation and racial erasure at the center of the history of the United States.

	Wasted Ventilation
		BEWARE OF Clearance of carbon dioxide is determined by the alveolar ventilation and the physiologic dead space.
		Alveolar dead space is caused by increased volume of zone 1 (zone 1 is where alveolar pressure exceeds the perfusion pressure to the lung unit: alveoli are ventilated but not perfused):
		It is important that you are aware of physiologic dead space (anatomical dead space plus alveolar dead space) in the modern setting of low tidal volume ventilation for acute lung injury (click here).

	Dead Space
		Dead space is always present as a component of the patient’s airway and, to a variable degree, as a component of the anesthetic system.
		Dead space also increases in a non-rebreathing system when fresh gas flows are inadequate or when certain defects are present in the system (for instance, when the center tube of a Bain system or F circuit is cracked or broken).
		The added dead space from the ET tube itself extending past the incisors is relatively negligible; a few tenths of an ml per cm excess tube for a 4 or 5 mm OD ET tube.

	Soviets' Salyut Station Paved Way for Mir
		As Russian cosmonauts and engineers prepare to return next week to their nation's presumed-dead space station, it is interesting to look back on the bumpy, and sometimes tragic road that led to Mir and Russia's position as the leading authority in space station technology and achievements.
		Although many worldwide space agencies, including Russia's, are devoting their energies these days to building the International Space Station, it was the Soviet Union that orbited the first space station in 1971.
		The Soviet achievement was the result of a courageous change of course for its space program in the 1970s that would turn it away from the moon, creating political and bureaucratic struggle in the process.

	Critical Care \| Full text \| Elimination of ventilator dead space in premature infants by flow partition: a new method
		This apparative dead space is commonly combated by high tidal volumes.
		A recently inaugurated alternative consists in flushing the anatomical dead space with fresh gas – which is split off the regular ventilation circuit – bypassing the apparative dead space.
		We conclude that the dead space decrease by split flow signs responsible for the reduced ventilation requirements, and would expect correspondingly less pulmonary injury.

		The randomness characteristic of real public space would be ensured as different speakers periodically solicited user's attention through banners running across the PublicNet icon.
		Theorists have suggested that arcades, the covered shopping streets of the 19th century served a similar purpose, and the Jane Jacobs generation declared the urban village, where the street was a shared experience, to be the most important public architecture of all.
		Kayden explained that while in 1961 the Seagram Building plaza was held up as a model for the use and design of privately-owned public space, the reality that ensued, when the zoning ordinance was revised to allow 10 square feet of bonus for each square foot of public space, had a less positive public impact.
