Flashcards in [AC] {WK2 + WK3} {Oxygen, Sputum Clearance, & Treatments} Deck (10):
1

What is the rationale for Positive Expiratory Pressure (PEP) devices for sputum clearance?

- Obtain temporary increases in FRC
- Allows TV to be above opening volume for otherwise closed airways
- Collateral ventilation to recruit alveoli and get air behind secretions
- FET to mobilise and clear secretions

2

What are some Oscillating PEP devices for sputum clearance?

Flutter, Cornet, Acapella

3

The use if nebuliser hypertonic saline prior to airway clearance can be considered to

increase sputum yield, reduce sputum viscosity and improve ease of expectoration

4

Delivery of oxygen to the tissues depends on three things?

1) Ventilation
2) Gas Exchange
3) Circulation

5

Physiological changes with inadequate oxygenation?

Increased RR
Increased HR
Increased Cyanosis (central/peripheral)

6

Oxygen therapy is for the treatment of

Hypoxaemia
NOT BREATHLESSNESS

7

Oxygen therapy devices can fit into what two categories:

- Low Flow (LF) Often Variable Performance
- High Flow (HF) Often Fixed Performance

8

What are some high flow devices for oxygen therapy?

- Venturi Mask
- Ambu Bag
- High Flow Nasal Prongs

9

What are some low flow oxygen therapy devices?

Nasal Cannula/Prongs
Simple Face Masks

10

What are the key components of oxygen therapy?

- The device
- FIO2 / Flow Rate
- Monitoring
