Mortality estimates for aspiration pneumonia vary. At least 5 percent of people who are hospitalized for aspiration will die. Among those with other complications, such as emphysema, the mortality rate rises to 20 percent or higher. Among geriatric populations, mortality skyrockets. A 2013 study of elderly patients put 30-day mortality at 21 percent. First responders, doctors, nurses, and other healthcare providers must always treat aspiration pneumonia as a medical emergency with a high mortality risk. Diligent airway management can prevent aspiration pneumonia in many emergent and surgical scenarios, and prompt emergency intervention can reduce aspirate volume in people actively aspirating.
The following signs of and risk factors for dying from aspiration pneumonia can help medical personnel take swift action to save lives.
Risk Factors for Aspiration Pneumonia
Patients face an increased risk of aspiration pneumonia when:
- They have a swallowing disorder.
- They have recently had a stroke. Forty percent of stroke survivors have swallowing dysfunction, which is a major risk factor for aspiration.
- They have dementia or another cognitive disability.
- They have an impaired gag reflex.
- They use sedating medications or are in an altered state of consciousness.
- They have a respiratory disorder.
- They have mobility impairments or a spinal cord injury.
- They have gastroesophageal reflux disease (GERD).
The patients who are more likely to die from aspiration include:
- Pediatrics and geriatrics
- People in poor health
- People with emphysema
- People who aspirate large volumes of fluid
Helping patients get into and sustain a safer position for swallowing can significantly reduce the risk of aspiration in those with the highest risk. It is also important for loved ones to monitor people with mobility impairments and cognitive disorders for signs of swallowing difficulties or food-related behavior that might increase the risk of aspiration.
Signs and Symptoms of Aspiration Pneumonia
When patients have impaired mobility, dysphagia, or breathing difficulties, medical personnel should always evaluate them for aspiration. Some signs and symptoms that increase the risk of dying from aspiration pneumonia include:
- Blue lips, tongue, or fingers
- Difficulty swallowing
- Shortness of breath or trouble breathing
- Chest pain
- Raspy sounds from the throat or chest
- Unexplained sweating
- Symptoms of a lower respiratory infection
Complications of Aspiration Pneumonia
In the immediate aftermath of aspiration, a patient may be unable to breathe or swallow, presenting a medical emergency. After the risk of hypoxia has passed, the dangers of aspiration pneumonia have not. Aspiration pneumonia can cause numerous complications, including:
- Respiratory failure
- Acute respiratory distress syndrome (ARDS)
- Bacterial pneumonia
People with the highest risk of dying from aspiration pneumonia may have swallowed large volumes of aspirate or have signs of infection. Continued monitoring can prove life-saving, especially in patients at risk of aspirating a second time.
The Right Treatment Matters
Aspiration presents an immediate risk of choking and hypoxia, so promptly clearing the airway is critically important. Following an aspiration event, patients may need hospitalization and continuous monitoring, especially if they swallowed a large volume of contaminated fluid.
The right suction machine can help you promptly intervene to stop or prevent aspiration and to reduce the volume of aspirate a patient inhales. The volume and content of the aspirate are the single biggest mortality predictors, so prompt intervention is a major predictor of survival. SSCOR offers a range of emergency portable suction machines that enable you to promptly tend to aspirating patients wherever they need care.
