Aspiration Pneumonia and Oral Health Flashcards
recipe for aspiration pneumonia
- colonization with pathogenic bacteria in upper airway
- aspiration of bacteria
- impaired host defence mechanisms
aspiration
inhalation of oropharyngeal secretions into the larynx and down to the lower respiratory tract
aspiration is common feature of
dysphagia
how to detect aspiration
objectively by radiographic studies (Video Fluoroscopic Swallow Study)
community acquired pneumonia timeline
outside hospital or after <3 days of hospitalization
community acquired pneumonia causative agents
Streptococcus pneumoniae
Haemophilus influenzae
community acquired pneumonia at risk population
history of smoking, alcoholism, chronic pulmonary disease
hospital acquired pneumonia timeline
after 3 or more days of hospitalization
hospital acquired pneumonia causative agents
Staphylococcus aureus
aerobic gram negative bacilli (AGNB)
hospital acquired pneumonia at risk population
older population with terminal disease
weak, frail, immunocompromised
aspiration pneumonia
bacterial infection that results from aspiration of bacteria that are pathogenic to the lungs (not viruses or blood borne pathogens)
aspiration pneumonitis
acute lung injury following the inhalation of regurgitated acidic gastric contents
risk increases with reduced level of consciousness
mechanism 1 of pathogen colonization
increased dental plaque
mechanism 2 of pathogen colonization
decreased buffering and antimicrobial capacity of saliva
pneumonia risk factors
inadequate provision of oral care
dependency for feeding and oral care
elevated levels of anaerobic and aerobic bacteria in plaque and oral secretions
