- Pseudomonas aeruginosa
- Acinetobacter baumannii
- Stenotrophomonas maltophilia
- Clostridium difficile
- Urinary tract infection
- Hospital-acquired pneumonia (HAP)
- GastroenteritisVancomycin-resistant Enterococcus
Ventilator-associated pneumonia (VAP)
People on mechanical ventilation through an endotracheal or tracheostomy tube for at least 48 hours.
Cause of VAP Ventilator Associated Pneumonia
- Normally pneumoniae is caused by S. pneumoniae, H. influenzae, or S. aureus.
- However, in the hospital the organism associated with pneumonia is most often Pseudomonas,
Signs and symptoms VAP
fever, low body temperature, purulent sputum, and hypoxia (decreasing amounts of oxygen in the blood).
- increasing numbers of white blood cells
- new shadows (infiltrates) on a chest x-ray as is indicative of a pneumonia
- Blood cultures may reveal the microorganisms causing VAP
- facultatively anaerobic, gram-positive coccus and is the most common cause of staph infections.
- nosocomial infections, often causing postsurgical wound infections.
Methicillin-resistant Staphylococcus aureus
- troublesome in hospitals, where patients with open wounds,
- invasive devices and weakened immune systems are at greater risk of infection than the general public
- gram-negative bacterium, which is resistant to most antibiotics
- severe pneumonia and infections of the urinary tract, bloodstream and other parts of the body.
