The ARMA trial: Lower tidal volume ventilation in ALI/ARDS [Classics Series]

1. The trial was terminated early when the data demonstrated that lower tidal volume ventilator settings in ALI/ARDS patients led to a significant decrease in in-hospital mortality. 2. Low tidal volume ventilation also led to an increase in ventilator-free days and a decrease in the number of days with systemic organ failure. There was no change in the incidence of barotrauma between the two groups.

Volume control ventilation

The earth's atmosphere is a mixture of gases and water vapour. An understanding of physical and thermodynamic properties of air-water vapour mixtures (psychrometrics) is fundamental to the design of environmental control systems for plants, crops, animals or humans. Properties of Moist Air Pressure, volume, density and thermal properties are related by the use of the laws for a 'perfect gas'. For a mixture of dry air and water vapour this law can be used with only negligible error at the range of temperatures and pressures used for environmental control.

Vaughan Metropolitan Centre Station

Overview The Vaughan Metropolitan Centre Station design was developed in response to existing site constraints, available undeveloped land and an evolving vision for a new urban centre. The interchange is well integrated into the future urban context of the Vaughan Metropolitan Centre, while offering high quality materials, generous circulation, intuitive wayfinding and efficient bus to subway transfers.

Alcohol (Ethanol) Poisoning Authored by: Becky Lundgren, DVM Dogs and cats can get more than just drunk when they drink alcoholic beverages -- they can get a trip to the emergency room. Pets can die from alcohol ingestion. Alcoholic drinks contain a lot of ethanol (ethyl alcohol, grain alcohol). Typical alcohol percentages for alcoholic beverages are: beer at 3% to 5% ethanol, wine at 9% to 12%, and whiskey at 40% to 90%.

Venturi ventilation

The pressure in one point of the network is the sum of energies of dynamic and static pressures. These transformations of energy are reversible or irreversible the pressure loss is irreversible loss of pressure because the head loss is converted into heat or noise that we do not know re-transformed into pressure. The pressure generated by changing altitude or height of load (hydrostatic pressure) is reversible: If the duct up of 1 meter, and down of 1 meter, the balance is zero:l: the pressure generated by the change in velocity (dynamic pressure) is reversible:If for a given flow a converging cone accelerates the fluid the pressure decreases (see Bernoulli), but if another diverging cone, positioned downstream, slows down the fluid to its original speed, the balance of dynamic pressure is zero: Venturi nozzle calculation according to the Bernoulli's Theorem The Bernoulli equation can be considered as a principle of conservation of energy, suitable for moving fluids.

In the south shaft, Dixon and his associate James Grant found a small bronze hook. The north shaft yielded a granite ball and a portion of cedar-like wood. They became known as the Dixon Relics. Both sets of artifacts lay amongst rubble at the bottom of the sloping shaft. The relics were taken to England, recorded by astronomer Royal Scotland, and returned to Dixon – after which they disappeared.

LINC Study Finds Mechanical Chest Compressions Are Equally as Effective as Manual CPR

Amsterdam, The Netherlands - Saturday 1 September 2013 – Mechanical chest compressions with defibrillation during ongoing compressions are just as effective, but not superior to manual compressions, for delivering cardiopulmonary resuscitation (CPR) to patients in cardiac arrest, according to the results of the LUCAS in Cardiac Arrest (LINC) study. "The study was designed to show a better 4-hour survival in the group treated with mechanical chest compressions, and this was not achieved," said lead investigator Sten Rubertsson, MD, PhD, professor and specialist consultant at Uppsala University and Uppsala University Hospital.

Xbox 360 slim unit shuts down if ventilation is insufficient?

Microsoft 's new slim Xbox 360 console will not display a red ring of death (RROD) as we reported already, but the system does take some measures to protect itself against heat-related damage that the older units don't. It was reported recently that the three blinking red lights had been replaced with a single "red dot of death". but the red dot may not indicate that the console is broken. Pictures posted on the NeoGaf forums by "Giant Robot" show an Xbox 360 250GB model displaying the red dot of death, and also an on-screen message alerting the user: "The Xbox 360 is shutting down to protect the console from insufficient ventilation.
