Case Study of Dudley Dawes: Development of pneumonia
Case study of Dudley Dawes
- Focus Area 1:
Aetiology of pneumonia
Pneumonia is considered an inflammatory condition of the lung which can affect the small air sacs known as alveoli. Pneumonia can be used to describe any inflammation of the lungs (American Lung Association, 2018).
The inflammation can be initiated by the microorganism like bacteria, fungus, virus, or bacteria-like an organism. Therefore, the common cause of bacterial pneumonia is Streptococcus pneumonia (World Health Organization, 2018). These organisms can infect the lung after having a cold or flu. It can affect the lobe of the lung. Thus, Mycoplasma pneumonia is also responsible for developing pneumonia in human. It is a bacterium-like an organism which can produce mild symptoms of pneumonia. This type of pneumonia is considered mild pneumonia which can be treated easily. In addition, people with chronic health problems or multiple diseases which weakened their immune system are prone to develop fungal pneumonia. The responsible fungi are present in soil and bird dropping. However, it is restricted in specific geographic areas. Therefore, few viruses are responsible for flu and cough. They can precipitate pneumonia in human. It is a common type of infections among the children. It can be considered mild but in some cases, it can be fatal. Additionally, it has been isolated that some people are acquired pneumonia during their hospital stay. In such cases, bacterial pneumonia has been isolated (Mayo Clinic, 2018). This kind of pneumonia is required an emergency response as the responsible bacteria can be more resistant to antibiotic treatment and poor immunity adversely can affect the whole situation. In addition, people admitted to ventilation are often developed this kind of pneumonia in hospital settings.
Pathophysiology of pneumonia
The pathophysiology of pneumonia stated that the invading organism can provoke the exuberant immune response in the lungs. Therefore, the blood vessels in the lungs become leaky and protein-rich fluid can deposit in alveoli (Science.jrank, 2018). As a result, less functional area for the gas exchange can deprive the patient of oxygen. Thus, the patient can feel rapid and fast breathing and require more effort to inhale oxygen and exhale carbon dioxide. In addition, mucus production is also increased. Thus, the leaky blood vessels can tinge the blood with the mucus. Therefore, the mucus plugs can farther decrease the gas exchange procedures in the lungs (Science.jrank, 2018) . In such condition, large numbers of white blood cells are produced to fight against the infections, however, make the alveoli fill with fluid and debris. In bacterial pneumonia, alveoli of the lungs get affected and in viral pneumonia, the wall of the alveoli and the parenchyma of the lungs get affected (Science.jrank, 2018).
Relate to the Case study
In the case of Dudley smoking and COPD can play a vital role in the development of pneumonia. It has been identified that the Streptococcus pneumoniae infection is very common among the COPD patients (Almirall, Blanquer & Bello, 2014). It has been established that the adherence of Streptococcus pneumoniae to the epithelial cells of the oral cavity of the smokers can persist for years after cessation of smoking. Therefore, in the case of Dudley, smoking can impair his immune strength and increase the risk of pneumonia (Almirall, Blanquer & Bello, 2014).
Therefore, his COPD is also enhancing the complication and chances of pneumonia. Dudley has suffered from type 2 diabetes which can reduce his immunity and make him prone to develop infectious diseases. High glucose level can provoke the bacteria to generate pneumonia (Kornum et al., 2007). It can be assumed that poor immune system of Dudley due to several health disorders and diseases makes him susceptible for developing pneumonia by the opportunity bacteria like Staphylococcus aureus, Klebsiella pneumoniae, and Pseudomonas aeruginosa (Healthline, 2018).

Sign and symptoms of pneumonia
The sign and symptoms of pneumonia can vary according to the severity of the disease the type of infections and the age of the patient. General sign and symptoms are chest pain, cough, and fatigue; poor mental status, fever, sweating, shaking, and low body temperature along with shortness of breath, nausea and vomiting (WebMD, 2018).
The symptoms of lung infections are slower than flu but faster than cold. The germs are getting down into the lung and cause further infections. Therefore, pneumonia has common symptoms like flu but it also has a high fever, greenish cough, bloody mucus, breathlessness, low appetite, fast heartbeat (WebMD, 2018).
Clinical presentation of pneumonia
The findings of Physical examination can vary depending on the severity of the disease, type of infections, the presence of complications, and coexistence of host factors (WebMD, 2018). The physical finding can reveal the following situation-
- Breathing with inconvenient sounds.
- Decreased intensity of breathing sounds.
- Tracheal deviation
- Pleural friction rub
The examination finding can indicate specific etiology of the disease. Therefore bradycardia can indicate Legionnaires disease, bullous myringitis can indicate Mycoplasma pneumoniae infection, evident of aspiration can include a decreased gag reflex and CNS findings can suggest the Nocardia infection.
History would help to identify the potential exposure, aspiration risk, and host factors of the patients.
- Potential exposure
A history of various exposures would help in determining the possible chance of infections (Thompson, 2016). Therefore, the important criteria’s are-
- Exposure to contaminated air or water causes infection due to Legionella species.
- Exposure to overcrowd atmosphere can increase the chances of S pneumoniae, Mycobacteria, and Mycoplasma infections.
- Exposure to a domestic animal can increase the incident of C psittaci and F tularensis infections.
- Aspiration risk
Increased risk of Aspiration can also increase the incidence of secondary pneumonia infections. Therefore, consumption of alcohol, drug, poor mental health, congenital abnormalities, dysphagia along with seizure and Gastroesophageal reflux disease (GERD) can increase the chances of infections in human (Thompson, 2016).
- Host factors
Past medical history of the patient should get utmost priority as they have a strong relation with disease development. Therefore, asthma, COPD along with smoking and alcohol consumption can elevate the chances of pneumonia. In addition, analysis of medication along with social and family history would help in proper identification of the scenario (Medscape, 2018
Relate to a case study
In the case of Dudley, it has been observed that he has a mild fever as the body temperature is 38.6o C, his Respiratory Rate is quite high as he has breathing difficulties. Therefore, he is suffering from tachycardia due to high pulse rate along with high BP and shallow breathing. He has difficulties in communicating, loss of appetite and fatigue. The all above symptoms are indicating that he is suffering from pneumonia which needs emergency treatment. In the initial stage he thought that he might have a cold but gradually the cough becomes thick and green.
As Dudley was a heavy smoker and have COPD and Asthma. Thus the chances of infections are increased in many folds. In addition, he has Type 2 diabetes which can interfere with his immune system and make him vulnerable to infectious diseases. Additionally, his arthritis can also play a role in the development of pneumonia (Kelly, 2017). However, he is advised to take several medicines to improve his conditions but few drugs have some side effects which adversely affect the scenario. In this consent, Endone is a medicine used to relieve pain can cause sneezing and weakness (NPS MedicineWise, 2018). Omeprazole is a medicine used as a proton pump inhibitor to reduce the complication of GERD can often precipitate cold and cough along with fever (Cunha, 2017). Additionally, Ramipril is used to treat hypertension can cause a cough and poor immunity (Healthline, 2018). The inhaler Ipratropium Bromide used for a cough and cold symptoms are often participated sneezing and cough (Cunha, 2016).
Therefore, Dudley is an aboriginal widower with several diseases. His loneliness and morbid condition along with poor nutritional status and immunity can make him vulnerable to pneumonia. However, proper medical intervention can improve his situation gradually.

Potential complication of pneumonia
Pneumonia can cause Acute Respiratory Distress Syndrome (ARDS) which is considered as a severe lungs condition. In this situation air sacs are filled with fluid as a result fluid in the lungs can increase the carbon dioxide in the blood and lower the amount of oxygen (Healthline, 2018). Therefore, the vital organs are deprived of oxygen which is essential for their proper function and ultimately causes organ failure. Thus, ARDS can cause severe trauma in hospitalized patients and considered as life-threatening, an emergency condition (Healthline, 2018).
The common symptoms of ARDS are rapid breathing, fatigue of muscles, weakness, low blood pressure, discoloration of skin and nails, dry cough, and fever along with a headache, rapid pulse rate, and confusion. The risk factors for ARDS are old age, chronic lung infections, alcohol consumption, and smoking. It can create serious illness among the old age people, a patient with liver disease, and toxic shock (Healthline, 2018).
Management strategies for the complication
ARDS can be managed in the following way-
- Supply of Oxygen
The primary goal of the treatment is based on providing enough oxygen to avoid organ failure. In this aspect, mechanical ventilation machine or oxygen mask can be used. In this way force of air into the lungs can reduce the fluid present in sacs (Han & Mallampalli, 2015).
- Maintenance of body fluid
Maintenance of adequate fluid balance is essential in case of ARDS. Too much fluid intake can increase the fluid build-up in the sacs. However, water insufficiency can cause organ failure (Bein et al., 2016).
In case of ARDS few medications can be administrated to relive the complication (Healthline, 2018). In this respect antibiotics are administered to treat infections, analgesic drugs can be used to relieve the discomfort and blood thinner medicines can be given to avoid clotting in lungs.
- Pulmonary Rehab
The recovering process of ARDS needs pulmonary rehabilitation. This process of rehabilitation can strengthen the respiratory system by increasing lungs capacity (Bein et al., 2016). In this aspect life style modification, exercise, and proper training can be beneficial.
Relate to a case study
Aging is responsible for significant changes in the respiratory system and the gas exchange process (Aplaceformom, 2018). Therefore the structural changes of lungs and chest wall are responsible for the alteration. In the case of Dudley, age is a concerning factor which can cause ARDS which can create an additional burden on his respiratory system and functioning. Thus, his COPD is responsible for obstructive airflow which can enhance the chances of ARDS. In addition, increasing age is accountable for lower arterial PO2 due to reducing of alveolar surface, closure of airway, and a decrease of diffusion capacity of lungs (Aplaceformom, 2018). Any disease of lungs or injuries can develop ARDS. Therefore, the collapse of alveoli due to reducing surfactant can interfere with oxygen exchange of the blood and cause hypoxemic respiratory failure (Aplaceformom, 2018). In Dudley, the previous case history of COPD and habit of smoking can interfere with the occurrence of the collapse of alveoli. If Dudley develops ARDS, then the lack of oxygen in the blood can produce cytokines by the injured lungs and WBC which can lead to inflammation in the vital organs. As he has already suffered from several diseases, ARDS can adversely affect the whole scenario of recovery (Mercola, 2018).
The decrease in the level of oxygen in the blood caused by ARDS can cause leakage of certain proteins (cytokines) in the bloodstream which is produced by the injured cell of the lungs and white blood cells. Therefore, it can lead to inflammation and other complications in the vital organs (Patel, 2018) and can cause multi organ failure situation. Therefore, patients suffering from ARDS are unable to fight against the pathogens and as a result develop infectious diseases.
At last it can be concluded that the physical condition of Dudley is clearing showing the symptoms of hospitalised pneumonia which can be treated by emergency medical intervention. In many cases, it has been observed that untreated pneumonia could precipitate severe complication which can be life threatening. Thus, early detection in case of Dudley could be beneficial; however, other physical complications of Dudley can delay the recovery process. He has COPD and Diabetes which can adversely affect the recovery process of pneumonia. Therefore, early identification and quick intervention is essential for treating pneumonia.
