Triggered by allergies

Q

What is COPD?

A

Different elements with the symptoms dependent on elements
Causes increased work of breathing
Acute exacerbation can lead to the pt getting pneumonia quickly and easily
Raised CO2 causes the brain not to respond, causing it to rely on low level O2 to make the pt breath

Q

What is alelectasis?

A

Common for post op pt and elderly pt
Collapsed alveoli at the base of the lung that need to be reopened
Can lead to T1RF

Q

How do you treat a pt with alelectasis?

A

Position and physio
Huff and cough are ways to reopen alveoli
Incentive spirometry = positive reinforcement to open alveoli

Q

How do you manage a pt with a chest drain?

A

Keep communication between pleural cavity and bottle, wants a “swinging” motion, needs to drain, monitor bubbling, never clamp tubing unless in emergency, keep below chest level, pain management

17
Q

What is the oxygenation aim for a pt with T1RF?

A

94-98%

18
Q

What is the oxygenation aim for T2RF?

A

88-92%

19
Q

When would you use a nasal cannula?

A

Long term oxygen therapy

Delivers low amount of O2 - don’t know % being delivered

20
Q

What are the positives of a nasal cannula?

A

Pt can mobilise, eat and drink, comfortable

21
Q

What is the function of high flow nasal O2?

A

Humidifies and moistens gas exchange

22
Q

When would you use a non-rebreathe mask?

A

All critically ill pts
Can’t know the % of O2 given to the pt
Short term

23
Q

What are the positives of using a non-rebreather mask?

A

Prevents re-breathing CO2

24
Q

What are the negatives of using a simple face mask?

A

Can’t know the % of O2 delivered

Won’t deliver more than 60% O2

25
Q

What is a Venturi?

A

Controls the percentage of O2 delivered to a pt

Need to know the % prescribed then use the matching adapter

26
Q

How would you deliver a nebuliser to a chronic respiratory pt?

A

Air

27
Q

How would you give a nebuliser to an acutely unwell pt?

A

O2

28
Q

Why would a pt be put on non-invasive ventilation (NIV)?

A

To support the rate and depth of breathing

29
Q

What are the different types of non-invasive ventilation (NIV)?

A

CPAP - high flow O2 to help open the alveoli

BiPAP/NIPPV - non-invasive, breaths for pt, delivers breath

30
Q

What are the different types of invasive ventilation?

A

Endotracheal

Tracheostomy

31
Q

What are complications of ventilating a pt?

A

Face mask - trapping leading to aspiration, pt self removing
Sedation for invasive ventilation - increased risk of pneumonia
Inflammatory problems

32
Q

What are the characteristics of type 1 respiratory failure?

A

Hypoxaemia

PaO2
