Oxygen Delivery Devices Exam 1 Questions with Correct Answers
(Grade A+)
Question 1: Goals of O2 Therapy
Answer: Treat Hypoxemia Decrease WOB Decrease Myocardial Work Anemia
Question 2: Purpose of O2 therapy
Answer: To Increase FIO2 and ultimately, the PaO2
Question 3: Low Flow Systems
Answer: Does not mean low FiO2 Does not meet the patient's total inspiratory flow needs Typically have
variable FiO2 levels Room air is entrained by the patient with each breath FiO2 level can only be
approximated
Question 4: FiO2 level is dependent upon patient's
Answer: Respiratory Rate and Pattern Tidal Volume
Question 5: Nasal Cannula
Answer: 2 Prongs (1 cm) are inserted into the tip of the nose Humidify if flow is >/= 4 L/min. FiO2 range:
24% to 44%
Question 6: Flow rates for infants using nasal cannula
Answer: </= 2 L/min
Question 7: Transtracheal Catheter
Answer: -Oxygen conserving device -A small thin catheter is surgically inserted directly into the trachea
-Only suitable for long term oxygen use
Question 8: FIO2 for transtracheal catheter
Answer: 22% to 35%
Question 9: Flow rates for transtracheal catheter
Answer: 1/4 to 4 L/min
