one from the other without exiting the facility (i.e., does not involve widely separated
locations or separate distinct practices). (FUN)
mV - Answer-Millivolt
Nasal Cannula - Answer-Device consisting of two short tubes to be inserted into the
nostrils to administer oxygen or other therapeutic gases. (MED)
Nebulizer - Answer-A device used for producing an aerosol of water and/or medication
within inspired gas supply. (MED)
Negative Pressure - Answer-Pressure less than atmospheric. (MED)
Nitrogen - Answer-An element that, at atmospheric temperatures and pressures, exists
as a clear, colorless, and tasteless gas; it comprises approximately four-fifths of the
earth's atmosphere. (MED)
Nitrogen NF - Answer-Nitrogen complying as a minimum with nitrogen NF. (PIP)
Nitrogen Narcosis - Answer-A condition resembling alcoholic inebriation, which results

used for inducing anesthesia when inhaled. The oxygen in the compound will be
released under conditions of combustion, creating an oxygen-enriched atmosphere.

comprising about 21 percent of normal air by volume, that is about 10 percent heavier
than air; also the physical state of the element at atmospheric temperature and
pressure. (MED)

(−300°F) at atmospheric pressure. It retains all of the properties of gaseous oxygen,
but, in addition, when allowed to warm to room temperature at atmospheric pressure, it
will evaporate and expand to fill a volume 860 times its liquid volume. (MED)
Oxygen Concentrator Unit - Answer-An engineered assembly of components that
operate to raise the concentration of oxygen, providing oxygen as a drug product. (PIP)
Oxygen Delivery Equipment - Answer-Any device used to transport and deliver an
oxygen-enriched atmosphere to a patient. (MED)
Oxygen Hood - Answer-A device encapsulating a patient's head and used for a purpose
similar to that of a mask. (HYP)
, Oxygen 93 USP - Answer-Oxygen complying with Oxygen USP 93 Monograph. (PIP)
Oxygen Toxicity (Hyperbaric) - Answer-Physical impairment resulting from breathing
gaseous mixtures containing oxygen-enriched atmospheres at elevated partial
pressures for extended periods of time. (HYP)

is intended to be used for diagnostic, therapeutic, or monitoring purposes in a patient
care vicinity. (MED)

intended to be examined or treated. (FUN)
Category 1 Space - Answer-Space in which failure of equipment or a system is likely to
cause major injury or death of patients, staff, or visitors. (FUN)
Space in which failure of equipment or a system is likely to cause major injury or death
of patients, staff, or visitors. (FUN) - Answer-Space in which failure of equipment or a
system is likely to cause minor injury to patients, staff, or visitors. (FUN)
Category 3 Space - Answer-Space in which the failure of equipment or a system is not
likely to cause injury to patients, staff, or visitors but can cause discomfort. (FUN)
Category 4 Space - Answer-Space in which failure of equipment or a system is not likely
to have a physical impact on patient care. (FUN)
Patient Care Vicinity. - Answer-A space, within a location intended for the examination
and treatment of patients, extending 1.8 m (6 ft) beyond the normal location of the bed,
chair, table, treadmill, or other device that supports the patient during examination and
treatment and extending vertically to 2.3 m (7 ft 6 in.) above the floor. (MED)
Patient Equipment Grounding Point - Answer-A jack or terminal that serves as the
collection point for redundant grounding of electric appliances serving a patient care
vicinity or for grounding other items in order to eliminate electromagnetic interference
problems. (MED)
