A resuscitator is a device using positive pressure to inflate the lungs of an unconscious person who is not breathing, in order to keep them oxygenated and alive. [citation needed] There are three basic types: a manual version (also known as a bag valve mask) consisting of a mask and a large hand-squeezed plastic bulb using ambient air, or with supplemental oxygen from a high-pressure tank.
In March 2014, Amazon announced an increase in the annual membership fee for Amazon Prime, from $79 to $99 for customers in the United States. [14] [21] Shortly after this change, Amazon announced Prime Music, a service in which members can get unlimited, ad-free streaming of over a million songs and access to curated playlists. [22]
An open circuit SCBA typically has three main components: a high-pressure gas storage cylinder, (e.g., 2,216 to 5,500 psi (15,280 to 37,920 kPa), about 150 to 374 atmospheres), a pressure regulator, and a respiratory interface, which may be a mouthpiece, half mask or full-face mask, assembled and mounted on a framed carrying harness.
A typical nominal regulated gauge pressure from a medical oxygen regulator is 3.4 bars (50 psi), for an absolute pressure of approximately 4.4 bar and a pressure ratio of about 4.4 without back pressure, so they will have choked flow in the metering orifices for a downstream (outlet) pressure of up to about 2.3 bar absolute.
In an atmosphere that may be oxygen-deficient, or toxic, an air supply can be carried on the back. A breathing apparatus or breathing set is equipment which allows a person to breathe in a hostile environment where breathing would otherwise be impossible, difficult, harmful, or hazardous, or assists a person to breathe.
Transformers: Prime (known as Transformers: Prime – Beast Hunters during its third and final season) is an American animated television series based on the Transformers toy franchise by Hasbro that aired on the Hub Network from November 29, 2010, to July 26, 2013.
The Chrysler Firepower was a Dodge Viper-based concept car produced in 2005. It takes some of the styling cues from the Chrysler Crossfire . According to Chrysler , its 6.1 L Hemi V8 engine produced 425 hp (317 kW) and could propel the vehicle to a 0-60 mph time of 4.5 seconds and had a top speed of 174 mph.
Medical use liquid oxygen airgas tanks are typically 2.4 MPa (350 psi). [citation needed] All equipment coming into contact with high pressure oxygen must be "oxygen clean" and "oxygen compatible", to reduce the risk of fire. [3] [4] "Oxygen clean" means the removal of any substance that could act as a source of ignition. "Oxygen compatible ...
