The respiratory therapist receives an order to set up a moderate level of oxygen on a patient who arrives
in the ED breathing at a rate of 35 BPM. Which of the following is most appropriate to use?
1. Simple O2 mask at 10 LPM
2. Nasal cannula at 4 LPM
3. Nonrebreathing mask at 15 LPM
4. Air-entrainment mask at 40% O2 correct answersSimple mask at 10 LPM
The physician has ordered oxygen to be set up on a patient who has a spontaneous tidal volume of 500
mL and an inspiratory time of 1 second. Which of the following devices will deliver a flow that meets or
exceeds this patient's inspiratory flow?
1. 35% air entrainment mask at 6 LPM
2. 60% aerosol mask at 12 LPM
3. NRB at 15 LPM
4. Simple O2 mask at 10 LPM correct answers35% air entrainment mask at 6 LPM
Use inspiratory flow equation: flow rate = L/t
0.5 L/1 second = 0.5 LPS
0.5 x 60 = 30 LPM at least must be delivered
Find air/O2 ratio:
100-35=65
35-21=14
65/14 = 4.64, so ratio is 5:1
5+1 = 6 x 6LPM = 36 LPM delivered by the air entrainment mask
,While making oxygen rounds, you discover the 6 inch reservoir tubing on a 60% T-piece set up has fallen
off. What may result from this situation?
1. The FiO2 could decrease
2. The total flow to the patient could increase
3. More room air entrainment could occur correct answersFiO2 decrease and room entrainment can
occur
A patient is using a 30% air entrainment mask at an O2 flow of 5 LPM. What is the total flow being
delivered? correct answers100-30 = 70
30-21 = 9
70/9 = 7.7, so 8:1
8+1 = 9
9x5 LPM = 45 LPM
Large cylinders use which type of safety system? correct answersASSS (american standard safety system)
*different number of threads/inch and different thread size
Small cylinders use which type of safety system? correct answersPISS (pin index safety system)
Color of carbon dioxide tank correct answersgray
Color of nitrous oxide tank correct answerslight blue
Color of helium tank correct answersbrown
,color of oxygen tank correct answersgreen
Duration of cylinder equation correct answers(cylinder pressure x cylinder factor)/flow rate
Cylinder factors for H & E cylinders: correct answersH = 3.14
Indications for this include hypoxemia, labored breathing or dyspnea, and increased myocardial work
correct answersO2 therapy
patients with COPD should maintain a PaO2 between __-__ mmHg correct answers50-65
High oxygen concentrations in the lung can wash out nitrogen and reduce the production of what,
leading to atelectasis? correct answerssurfactant
If a normal PaO2 level cannot be maintained with a 60% O2 mask, a large shunt is probable and ____
should be administered if CO2 is normal correct answersCPAP
Normal PaO2 for infants correct answers50-70 mmHg
When given a patient using 60% O2 or higher who has a normal or low PaCO2 but has hypoxemia, place
the patient on _____
(unless they have hypotension, low CO, or increased ICP - increase FiO2 in these cases) correct
answersCPAP
, What is the most effective measurement to determining the O2 carrying capacity of a patient's blood
correct answersCaO2
May cause anemic hypoxia, most commonly caused by nitrite poisoning. Treat by administering ascorbic
acid or methylene blue correct answersMethemoglobin
CaO2 equation correct answers(1.24 x Hgb x SpO2) + (0.003 x PaO2)
an o2 delivery device that does not meet the patient's inspiratory flow demands; therefore room air
must make up the remainder of the patient's tidal volume. Not used for inconsistent ventilatory patterns.
correct answersLow flow O2 system
Dlivers 35-50% O2 at flow rates of 5-10 LPM, Flow of 5 is required to prevent Co2 buildup in the mask
correct answersSimple mask
Delivers 40-70% O2 at flow rates of 10-15 LPM correct answersPartial rebreathing mask
Delivers 60-80% O2 at flow rates of 10-15 LPM correct answersNRB
What are the low flow delivery devices? - 5
(regular ventilatory pattern, RR less than 25, Consistent Vt or 300-700) correct answers1. Transtracheal
catheter
2. Nasal cannula
3. Simple O2 mask
4. Partial rebreathing mask
5. Nonrebreathing mask
Increasing the flow rate on high flow devices will or will not increase FiO2? correct answerswill not
What are the high flow o2 devices? - 6 correct answers1. Air entrainment mask
