Flashcards in Lecture 2 Part 3 Deck (12):
1

What are some Variable performance Devices?

Nasal canula, Simple face mask, Non-rebreather mask

2

What is the oxygen concentration for Nasal cannula?

2-6 Ltrs, 24-35%

3

What is the oxygen concentration for a simple face mask?

5-12 Ltrs, 24-60%

4

What is the oxygen concentration of a non-rebreather mask

10-15 Ltrs - >60%

5

What is a fixed performance device? (O2 delivery systems)

Provide sufficient flow of gas to meet all the needs of the patients minute ventilation. O2% determined by flow rate not pt RR

6

What is a common Fixed performance device (O2 delivery)

Venturi mask

7

What are some indications for putting a patient on >60% O2?

Cardiac/Respiratory arrest, Acute respiratory distress, Hypotension, Asthma, Pulmoanry Embolism

8

What is a Variable Performance device (O2 delivery systems)

O2 delivery system that doesn’t provide all the gas necessary for minute ventilation. O2 concentration depends on amount delivered

9

What is Central cyanosis?

Systemic shortage of Oxygen

10

What are the 2 phases of breathing?

Inspiration and expiration

11

What is the normal pH values of arterial blood gases?

pH 7.35-7.45

12

Does the pH alone indicate acid base balance?

No – pH, PCO2 and HCO3 must all be within normal range, if any of them aren’t that indicates an acid base imbalance
