Published	12/13/2023	The processing component of the SPDD model is located from the {{c1::anesthesia machine}} to the {{c1::common gas outlet}}.
Published	12/13/2023	The delivery component of the SPDD model consists of the {{c1::breathing circuit}}.
Published	12/13/2023	The disposal component of the SPDD model consists of the {{c1::scavenging system}}.
Published	12/13/2023	What are the five tasks of oxygen in the anesthesia machine?1. {{c2::O2 pressure failure alarm}}2. {{c3::O2 pressure failsafe device (N2O shutoff)}}3.…
Published	12/13/2023	The cylinder {{c1::valve}} is the most delicate part of a cylinder.
Published	12/13/2023	Gas cylinders must be stored in the {{c1::upright}} position.
Published	12/13/2023	If there is an empty cylinder slot on the anesthesia gas machine, a {{c1::yoke plug}} should be inserted to guard against check valve failure.
Published	12/13/2023	What is the maximum number of washers that can be placed between the cylinder and the hanger yoke assembly?{{c1::1}}
Published	12/13/2023	Cylinders should not be exposed to temperatures higher than {{c1::57}}°C.
Published	12/13/2023	What regulatory agencies sets the standards for required components of the anesthesia machine?{{c1::American Society for Testing and Materials (ASTM)}…
Published	12/13/2023	What regulatory agencies sets the standards for compressed gas cylinders?{{c1::Department of Transportation (DOT)}}
Published	12/13/2023	What regulatory agencies sets the standards for anesthesia machine pre-use checkout procedures?{{c1::Food and Drug Administration}}
Published	12/13/2023	What regulatory agency sets the standards for occupational exposure to volatile anesthetics?{{c1::Occupational Safety and Health Administration (OSHA)…
Published	12/13/2023	All cylinders are tested for leaks at {{c1::1.66}} times of its service pressure.
Published	12/13/2023	Oxygen failsafe devices on {{c1::GE Datex-Ohmeda}} anesthesia machines have an all-or-nothing response.
Published	12/13/2023	Oxygen failsafe devices on {{c1::Drager}} anesthesia machines will produce proportionate reductions in nitrous oxide flow.
Published	12/13/2023	{{c1::Baffles and wicks}} in a vaporizing chamber increase surface area and turbulence, which ensures 100% saturation of gas.
Published	12/13/2023	The {{c1::latent heat of vaporization}} is the number of calories needed to convert 1 g of a liquid into vapor without changes in temperature.
Published	12/13/2023	The {{c1::pumping}} effect increases vaporizer output by causing gas to re-enter the vaporizer.
Published	12/13/2023	The pumping effect generally occurs with {{c1::positive pressure}} ventilation or use of the {{c2::oxygen flush valve}}.
Published	12/13/2023	The most common cause of a vaporizer leak is a {{c1::loose filler cap}}.
Published	12/13/2023	In closed circuit (low flow) anesthesia, the amount of oxygen delivered is based on {{c1::oxygen consumption}}.
Published	12/13/2023	An {{c1::ascending}} bellow rises during expiration.
Published	12/13/2023	A {{c1::descending}} bellow falls during expiration.
Published	12/13/2023	{{c1::Ascending}} bellows are safer because it will not fill if there is a disconnect.
Published	12/13/2023	Gas-driven bellow automatically add {{c1::2-3}} cm H2O of PEEP from the ventilator spill valve.
Published	12/13/2023	The breathing bag {{c1::inflates}} during inspiration and {{c1::deflates}} during expiration.
Published	12/13/2023	A {{c1::circuit disconnection}} is signaled by a rapidly deflating breathing bag.
Published	12/13/2023	The addition of {{c1::calcium sulfate}} and {{c2::polyvinylpyrrolidone}} to calcium hydroxide lime increasees the hardness.
Published	12/13/2023	The most common cause of low pressure in a breathing circuit is a {{c1::circuit disconnection}}.
Published	12/13/2023	A malfunctioning {{c3::ventilator spill valve}} manifests as {{c1::high peak pressures}} that is relieved by {{c2::removing the patient from the venti…
Published	12/13/2023	During mechanical ventilation, the {{c1::ventilator spill valve}} determines the amount of gas released to the scavenger.
Published	12/13/2023	During {{c1::spontaneous}} ventilation, the APL valve determines the amount of gas released to the scavenger.
Published	12/13/2023	What type of scavenging system does not require the use of a pressure relief valve?{{c1::Open system}}
Published	12/13/2023	A closed, passive scavengning system must have a {{c1::positive}} pressure relief valve.
Published	12/13/2023	A closed, active scavenging system must have a {{c1::positive and negative}} pressure relief valve.
Published	12/13/2023	Failure of the {{c1::positive}} pressure relief valve in a scavenging system can cause {{c2::barotrauma}}.
