Pathophysiology for Paramedic Student

The ability to communicate your knowledge in oral and written formats is a core academic skill set you should acquire whilst at University.
Learning Outcomes
Successful completion of this assignment should allow you to:
– demonstrate an understanding of the pathophysiology, diagnosis and prehospital management of patients with respiratory-related conditions,
– apply an integrated understanding of the anatomy and physiology of body systems to paramedic practice,
– define and effectively convey clinically relevant information in an organised and logical fashion,
– support your viewpoints with sound reference sources and where possible provide a balanced critical assessment of the evidence base used to

inform accepted clinical practices,
– broaden your understanding of the relationships between body systems and the development of pathology/pathophysiology

Assignment Requirements

A 1500 word, structured response answering the specific questions presented in the following case study.

• Information provided in your answers must be referenced following academic conventions. A bibliography should be included at the end of your

document conforming to Harvard (author/date) format. References and in text citations are not included in the word count.
• Diagrams can be included to help support your answers – they are not included in the word count.
• Use the answer template provided by pasting it into a new document

Integrated Clinical Case

Patient Background
You have been tasked Priority 2 to a 75 year old man with chest tightness and shortness of breath. On your arrival you find a very thin, elderly

man sitting on a chair with his arms braced on his knees. He looks very dyspnoeic. His initial observations are:

Respiratory rate 45 breaths/minute
Heart rate 120 beats/minute
Blood Pressure 95/50 mmHg
Oxygen saturation 82%
Glasgow Coma Score 13 (E=3,V=4, M=6)

The man’s name is Mr Wenham, and he is only able to speak single words. His wife tells you that his breathing is never very good, because he smoked

far too much. She says he sometimes struggles to walk around the house.

Symptoms Shortness of breath, chest tightness, cough
Onset “His breathing has been particularly bad for the last two days and much worse for the last hour or so”
Chest examination Barrel chested, little chest wall movement
Breathing sounds Very quiet breath sounds, occasional wheeze
Jugular veins Elevated 5cm

 

You form the view that Mr Wenham is suffering from an exacerbation of Chronic Obstructive Pulmonary Disease (COPD). You administer supplemental

oxygen, atrovent and salbutamol (following local guidelines), and prepare for the 60 minute journey to hospital.

1. Describe the underlying pathology of COPD and the common pathological characteristics of the condition. Discuss the impact these

pathological changes have on normal function, including how alveolar ventilation might be different in Mr Wenham compared to a normal individual.

(20 marks)

2. Discuss why you would administer salbutamol and describe how it works at the cellular level. (10 marks)

Mr Wenham’s oxygen saturation improves with supplemental oxygen but he remains tachypnoeic, tachycardic and hypotensive. On arrival at the

Emergency Department you go straight to the resuscitation room and an arterial blood gas sample is taken and analysed immediately with the following

results:

 

pH 7.12
PaO2 100 mmHg.
PaCO2 110 mmHg
HCO3 38

 

3. Discuss why they would take an arterial blood gas and explain what the results mean and how they relate to the pathophysiology you

described. (10 marks)

The emergency department staffsuggest you may have given Mr Wenham too much oxygen. They say they are going to remove the oxygen.

4. Overview the normal physiological control of breathing. Then, identify and discuss the issues surrounding the use of supplemental oxygen

therapy in patients with severe exacerbations of COPD. What problems can it cause and why? (20 marks)

5. When considering his blood gas analysis, do you think it is a good idea to remove Mr Wenham’s oxygen and have him just breathing air?

Provide an argument supporting why it is OR why it is not.(10 marks)

The emergency department consultant returns from his lunch break to interrupt the oxygen debate. He suggests that Mr Wenham needs BiPAP.

6. What is BiPAP? How might BiPAP help to improve Mr Wenham’s clinical condition? (10 marks)

Three days later, after 18 hours of BiPAP, corticosteroids and physiotherapy, Mr Wenham is much improved. The respiratory physician responsible for

his care orders spirometry. This shows:

 

FEV1 0.75 litres
FVC 1.5 litres
FEV1/FVC 50%

 

7. What is spirometry? (5 marks)

8. Discuss the significance of the results by examining the differences between Mr Wenham’s spirometry and that of a normal individual?(10

marks)

9. How does the pathology of COPD explain these differences? (5 marks)
