RCP 130 Exam questions well
answered already passed
What are the calculation factors? - correct answer ✔✔Flow per minute multiplied by the heliox
factor
· 80:20 Heliox mixture is 1.8, therefore if the flow is set at 10L/min 10 x 1.8 = 18 L/min - The RT
can then set the desired flow by dividing the flow by the Heliox factor (for example if a flow of
9L/min of an 80:20 heliox mixture is needed, the RT sets the flow meter to .8 = 5 L/min)
· 70:30 Heliox mixture is 1.6
What are the properties of heliox? - correct answer ✔✔· Helium and Oxygen (helium has a
lower density than oxygen)
How can heliox administration benefit a patient? - correct answer ✔✔· Decrease the patients
WOB by delivering low density gas that can easily move around obstructions.
· Because of a lower density heliox descreases effective flow resistance in patients with upper
airway obstruction. Can be given to a patient with severe asthma to reduce work of breathing
by reducing turbulent flow.
What are the properties of nitric oxide? - correct answer ✔✔· A colorless, odorless gas that is
highly diffusible, lipid-soluble free radical that oxidizes quickly to nitrogen dioxide (NO2) in the
presence of O2, nonflammable, toxic gas that supports combustion
What patients can benefit from nitric oxide? - correct answer ✔✔· Use in conjunction with
mechanical ventilation, in treating term and near term (>34 weeks) neonates with hypoxic
respiratory failure with associated pulmonary hypertension (mainstay therapy)
· In adults, NO has been effective in treating pulmonary hypertension associated with acute
respiratory distress syndrome (ARDS)
· Improves Blood flow to Ventilated Alveoli- Relaxes Smooth Muscle
, What kind gas supply systems are located at hospitals? - correct answer ✔✔· 3 types of
centrally located gas supply systems
· Cylinder manifold system à large (H or K size) cylinders of compressed O2 banked together in
series, includes a primary and reserve bank.
· Fixed cylindersà permanent tanks can be refilled at stationary site
· Cylinder supply system with reserve supply à includes a primary, secondary, and reserve
supply.
· Liquid Bulk gas system with a reserve
What is each safety index connector used with? - correct answer ✔✔· PISS (Pin Index Safety
System) - applies only to the valve outlets of small cylinders, up to and including size E.
· ASSS (American Standard Safety System) - provides standards for threaded high-pressure
connections between large compressed gas cylinders (sizes F through H/K) and their
attachments
· DISS (Diameter Index Safety System) - typically found at the outlets of pressure-reducing valves
attached to cylinders; at the station outlets of central piping systems; and at the inlets of
blenders, flowmeters, ventilators, and other pneumatic equipment.
Why are zone valves important? - correct answer ✔✔· They also work as shut-off valves,
isolation valves, or section valves.
What situations may you need to access zone valves? - correct answer ✔✔· Healthcare
professionals can access these in the event of an emergency or if maintenance or repair of the
central gas supply is necessary.
What are the advantages? - correct answer ✔✔Advantages: true flowmeter that measures gas
flow, can either be pressure compensated or uncompensated, they are calibrated to produce an
accurate flow rate of 50 psi.
