what is hospital acquired pneumonia, describe
Nosocomial
- Onset of pneumonia symptoms more than 48 hours after admission to the hospital
- Host defenses are impaired, inoculum of organism reaches the patient lower resp tract and over-whelms the host defenses or highly virulent organism is present
what are the factors affecting hospital acquired pneumonia
-coma
-comorbidity
malnutrition
-prolonged hospitalization
-hypotension
-metabolic disorders
what is community acquired pneumonia
- Occurs in the community setting or within the first 48 hours of hospitalization or institutionalization
- Hospitalization depends on the severity
what is the immunocompromised host
Occurs with use of corticosteroids or other immunosuppressive agents, chemotherapy, nutritional depletion, use of broad-spectrum antimicrobial agents, acquired immunodeficiency syndrome, genetic immune disorders, long term advanced life support
what is aspiration pneumonia
-Pulmonary consequence resulting from the entry of endogenous or exogenous substances into the lower airway
where does aspiration pneumonia occur
Occur in the community or hospital setting
what enters in the system that causes aspiration pneumonia
Common pathogens into the airways
-Could also be gastric contents, exogenous chemical contents or irritating gases: may impair the lung defences, cause inflm changes, lead to bacterial growth and result in pneumonia
what Dx would you want for pneumonia
- chest x ray
- blood culture and sensitivity
- sputum culture and sensitivity
- WBC and differential
- Procalcitonin
- CRP
why is a chest xray done for pneumonia
-used to detect and help evaluate the severity of a lung infection
what findings would indicate potential pneumonia with a blood culture and sensitivity
-Detect septicemia when it is suspected that infection has spread from the lungs to the blood or from the blood to the lungs
what should you teach relating to sputum culture and sensitivity
- having pt rinse mouth with water to minimize contamination of normal oral flora
- breathe deeply several times
- cough deeply
- expectorate the raised sputum into a sterile container
what findings would indicate potential pneumonia with a sputum culture and sensitivity
gram stain: gram positive test detect that identifies the cause of bacterial pneumonia
what findings would indicate potential pneumonia with WBC’s/differentials
high levels of WBC’s
why is WBC and differential done?
to see type and number of WBC’s
what is procalcitonin?
a blood sample
-substance produced by many types of cells in the body, often responding to bacterial infections
what does high CRP indicate
presence of inflammation
Knowing what you have learned about the clinical manifestations and features of pneumonia list five nursing diagnoses that could occur when a patient has pneumonia.
- SOB r/t pneumonia
- Deep breathing, shortness of breath r/t impaired pulmonary fx
- Sputum r/t impaired ability to secrete sputum
- Crackles r/t pneumonia
- Fever r/t infection
For your listed nursing diagnoses, brainstorm some potential nursing interventions
- Spirometry
- Medications via nebulizers
- Other meds
- Encourage deep breathing
- Give pt oxygen
how is breathlessness described for a patient?
it’s a symptom that can only be described and interpreted by the patient
when is breathlessness common in pts
for those with advanced life-threatening illnesses of all types
describe breathlessness
• Temporal patterns of breathlessness, including continuous or episodic breathlessness, with or without apparent triggers, are a current topic of research in the hope that such discrimination will inform future management choices
what is the prevalence of breathlessness
• The prevalence reaches 90% in cancer, 95% in COPD, 88% in cardiac failure, 80% in end-stage renal disease and 85% in advanced neurological disease
what are signs of success in breathlessness
may be a reduction in intensity of breathlessness, a reduction in psychological distress, an increase in activity levels or a reduction in hospital admissions
what is the main pharm intervention for breathlessness
opioids
why are opioids used for breathlessness?
• Opioids are proposed both to reduce the spontaneous respiratory motor response to hypercapnia and hypoxia and to modulate the central processing with that perceptual sensitivity to breathlessness is diminished
who are most likely to benefit with opioids who have breathlessness
• Younger patients and those who experience the greatest severity of breathlessness are most likely to benefit
what is often prescribed for palliation of breathlessness in the setting of other advanced disease?
oxygen
is oxygen or opioids better for breathlessness?
• Opioids have been found to be significantly better than oxygen in reducing breathlessness
what are some non pharm interventions to help with breathlessness (i have 4 listed)
- forward positioning
- walking aid
- acupuncture
- pulmonary rehabilitation and exercise
why is forward positioning useful for breathlessness?
- fixes shoulder girdle
- improves efficacy of accessory muscles
why is pulmonary rehabilitation and exercise useful for breathlessness?
- desensitizes patient
- reduces deconditioning
- lowers ventilator demand and slows respiration
whats the benefit of a walking aid with breathlessness?
allows forward leaning and decrease in breathing during exercise. also increases pt confidence
what is dyspnea?
- Difficult or laboured breathing
- Shortness of breath, feeling as if you are not getting enough air
- Subjective experience

placing patient in semierect position
how can you reduce the pleural rubbing of the lungs to reduce discomfort with pneumonia?
lying on affected side (if pneumonia is unilateral) splints the chest on the side and can reduce the pleural rubbing that often causes discomfort
