Manufacture, Storage, and Transport of Medical Gases
Gases that supports combustion.
What are air and oxygen?
Gas flow from these flowmeters stops if resistance creates a back pressure that exceeds the source gas pressure
What is back pressure-compensated flowmeters?
43.9 mg/L
What is a gas at body temperature and ambient pressure (BTPS)?
Delivers oxygen only during inspiration.
What is the pulse demand oxygen delivery system?
Unit-Dose, Multiple Unit-Dose, Multiple Doses
What are the doses available in dry powder inhalers?
Brown medical gas cylinder.
What is the color of helium?
Used as a pulmonary vasodilator to treat persistent pulmonary hypertension of the newborn.
What is nitric oxide therapy?
Absolute humidity increases
What is when the temperature of a saturated gas decreases?
Used to deliver supplemental oxygen to infants.
1 to 5 um
What is the optimum range of aerosol particle sizes that are to be inspired for general deposition through upper and lower airways?
Safety system used with small cylinders, sizes “A” through “E”.
What is the Pin Index Safety System?
Partial obstruction of oxygen flow downstream of the jet orifice or partial obstruction of the entrainment ports.
What is reducing the amount of room air entrained resulting in raising the FIO2 of the delivered gas?
isometric saturation boundary (ISB)
What is the point at which inhaled gas reaches saturation?
Regulate temperature, humidity, and FiO2 of infants' environment.
hydrofluoroalkane
What is a pMDI propellant?
Pin positions for an “E” size oxygen cylinder?
What is 2 and 5?
Lower density gas used to treat of airway obstruction.
What helium-oxygen (heliox)?
100% relative humidity with an absolute humidity level of 36 to 40 mg/L at 31 degrees Celsius to 35 degrees Celsius.
What is the gas delivered to the midtrachea?
Uses two flowmeters that blend two gases to obtain desired FIO2.
What is a oxygen adder?
Metering Valve
What is the most critical component of the pMDI?
Semipermeable membranes provide 40% of oxygen at liter flows of 1 to 10 L/min.
What are oxygen concentrators?
1.8 x liter flow
1.6 x liter flow
What are heliox correction factors?
Captures and returns up to 70% of exhaled heat and humidity to patient to heat and humidify next inspiration.
What is the heat and moisture exchanger (HME), "artificial nose"?
Mixes 50 psig source of oxygen and air to obtain precise FIO2.
What is oxygen blenders and mixers?
Baffle
What is the reduction of particles inhaled?
