following.
N20
According to the U.S. Department of Commerce, a gas
cylinder that is brown should contain which of the following?
Helium
Which of the following mechanisms do all compressed
gas cylinders used to avoid excessively high
buildup of cylinder pressure.
high pressure relief valve
A cylinder is considered full at
2200 psig
Which device is used
to reduce the pressure and control the flow of a compressed
medical gas?
regulator
Specific clinical objectives of oxygen (O2) therapy include the
following?
1. decrease the symptoms caused by hypoxemia
,2. decrease the workload hypoxemia imposes on
the heart and lungs
3. correct document arterial hypoxemia
To minimize the risk of retinopathy of prematurity (ROP), the
American Academy of Pediatrics
recommends keeping the PaO2 below what level?
80 mmHg
There are two factors that determine the extent of harmful
effects of oxygen:
Pao2 and exposure time
To prevent absorption atelectasis keep Fio2 lower than
__________, if possible.
50 %
You must deliver the highest possible FiO2 to a 67-year-old man
with pulmonary edema breathing at a rate of 35/min. Which of
the following O2 delivery systems would be most appropriate?
Non- rebreather Mask 10-12 LPM
A simple Face Mask Fio2 range is :
35-50%
A nasal cannula Fi02 range is:
22%-40%
(You have 2 nostrils one on each side, 2x2=4 to help you
remember it goes to 40)
, Which of the following statements are true about low-flow O2
delivery systems?
2. All low-flow devices provide variable O2 concentrations.
3. The O2 provided by a low-flow device is diluted with air.
4. The patient's flow usually exceeds that from a low-flow
device.
To provide adequate tissue oxygenation a goal of a PaO2 of 55-
80 torr or a SpO2 of __________ is recommended
88- 95%
First two numbers of pa02 are double digit 55, first 2 of SpO2
double digit 88)
Specific clinical objectives of oxygen therapy include which of
the following?
1. Decrease the symptoms caused by chronic hypoxemia.
2. Decrease the workload hypoxemia imposes on
the heart and lungs.
3. Correct documented arterial hypoxemia
High flow systems provide:
1. equal or exceeds the patient's demand
2. provide at least 60 PLM
3. provide three times the average of an adult minute volume
An O2 delivery device takes separate pressurized
air and pressurized O2 source as input and
