LATEST QUESTIONS AND CORRECT
ANSWERS
What are the RESPIRATORY identifiable symptoms of hypoxia/hypoxemia? -
ANSWER- -Increased RR (tachypnea)
-Dyspnea (perceived SOB)
-Paleness (cyanosis=severe)
What are the CARDIOVASCULAR identifiable symptoms of hypoxia/hypoxia? -
ANSWER- -Mild hypertension (secondary to vasoconstriction)
*if severe, leads to eventual hypotension.
What are the NEUROLOGIC identifiable symptoms of hypoxia/hypoxemia? - ANSWER-
-Restlessness
-Disorientation
-Headaches
-Severe case lead to (distressed appearance, confusion, blurred vision, loss of
coordination, slow reaction time, somnolence, coma)
Patient need of 02 based on LAB DOCUMENTATION. - ANSWER- -Pa02 is <60mmHg
-Sp02 is less than 90% on RA.
Patient need of 02 based on CLINICAL findings at bedside. - ANSWER- -Tachycardia
-Tachypnea
-Confusion
Patient need of 02 via Non-rebreather based on SPECIAL CONSIDERATIONS. -
ANSWER- -Pneumothorax
-CO/ cyanide poisoning
-Acute myocardial infarction (MI)
Patient need of 02 via Simple Mask based on SPECIAL CONSIDERATIONS. -
ANSWER- -Post anesthesia
What are the LOW FLOW devices? (Hint: There are 7) - ANSWER- -Nasal Cannula
-Nasal Catheter
-Transtracheal Catheter
-Reservoir Cannula
-Simple Mask
-Partial Rebreather
-Non Rebreather
, What is the flow rate for a NASAL CANNULA? - ANSWER- 1/4-6L/min
What is the Fi02 rate for a NASAL CANNULA? - ANSWER- 24-44%
What is the flow rate for a SIMPLE MASK? - ANSWER- 5-10L/min
What is the Fi02 range for a SIMPLE MASK? - ANSWER- 35%-50%
What is the flow rate for a NON RE-BREATHER? - ANSWER- 10L/min-inflation of the
bag-15L
What is the Fi02 rate for a NON RE-BREATHER? - ANSWER- 60-80%
What is the conversion factor for an E tank? - ANSWER- 0.28
What is the conversion factor for an H tank? - ANSWER- 3.14
What is Patient Demand? - ANSWER- When you provide all of the 02 the patient is
inspiring and no RA is allowed in. (Minute Ventilation) x 3.
What factors are needed to calculate a Pts demand? - ANSWER- RR (Respiratory rate)
x Vt (Tidal Volume)= Ve (Minute Ventilation) x 3= Patient Demand
What type of relationship does the size of the jet to the Fi02 have? - ANSWER- Direct.
The size of the jet increases, the Fi02 increases.
What type of relationship does the size of the entrainment port to the Fi02 have? -
ANSWER- Indirect. The size of the port increases, the Fi02 decreases.
When do you need to increase the flow? - ANSWER- When the applied L/min is not
causing the Sp02 to return to normal.
Sp02 for normal patient= 95% and above
COPD patient= low 90%s
What is the total output for a venturi with the Fi02 of .35? - ANSWER- 5:1
What is the total output for a venturi with the Fi02 of .40? - ANSWER- 3:1
What is the total output for a venturi with the Fi02 of .50? - ANSWER- 2:1
What are the indications (uses) for NITRIC OXIDE? - ANSWER- -Improves blood flow
to the ventilated spaces in the lungs
-Reduces shunting
-Decreases pulmonary vascular resistance.
