This results in a leftward shift of the hemoglobin dissociation curve with impaired oxygen delivery and compounds the already‐present hypoxia. [shmabstracts.com]
Abstract Twenty new cases of Silo filler's disease (SFD) have been collected, documenting the incidence and clinical features of exposure to nitrogen oxides present in freshly filled silos. [ncbi.nlm.nih.gov]
Patients with acute hypersensitivity pneumonitis may present with a similar onset of acute shortness of breath, fever and lung infiltrates as silo-filler's disease. [nasdonline.org]

If you experience a persistent cough, shortness of breath, fatigue, or if you feel like you have a lingering cold or generally feel worn out, you should see your doctor. [nolo.com]

Impaired breathing also occurs as was measured by Scott and Hunt [12]. Sudden death has been reported due to exposure at extremely high concentrations of gas. [oatext.com]
- Sudden Infant Death Syndrome
It also worsens pre-existing lung diseases like asthma and has been implicated in sudden infant death syndrome (SIDS / cot death). The effects of nitrogen dioxide is compounded among silo workers because of repeated exposure. [healthhype.com]
Respiratoric
- Dyspnea
Approximately 8 hours later, he developed significant dyspnea, productive cough with dark sputum, fever, and malaise. The cough became dry subsequently. [shmabstracts.com]
The most common presenting feature was dyspnea. All victims entered a silo during the peak danger period, and only one used recommended ventilation techniques. Four cases ended in death (20% mortality). [ncbi.nlm.nih.gov]

- Nausea
Symptoms of silo filler’s disease include coughing, burning, shortness of breath, chills, fever, headache, nausea and vomiting. [farmsafevt.wordpress.com]
Initial nausea, cough and fever remitted, but respiratory failure developed 3 weeks later. Roentgenograms and lung function studies revealed pulmonary in the adult edema, volume restriction, and severely impaired gas exchange. [karger.com]
Symptoms of exposure to silo gas include coughing, burning, chills, fever and nausea. A farmer may also be exposed to silo gas, experience very mild or no symptoms and die while sleeping from fluid accumulation in the lungs. [canr.msu.edu]

Neurologic
- Headache
In addition to the potential for exposure to fatal asphyxia secondary to NO2 and other oxides of nitrogen, less severe exposure to nitrogen oxides produces transient pulmonary decompensation, cough, dyspnea, and headaches. [progressivegardening.com]

Workup
Pulmonary function tests (PFTs) should be performed as soon as possible, to establish a baseline See Workup for more detail. [emedicine.medscape.com]
X-Ray
- Ground Glass Appearance
CT scans show pulmonary cysts and a diffuse ground-glass appearance [19]. Patients who avoid contact with the antigen complex for a sustained period demonstrate relief from the disease. [oatext.com]

Treatment
The treatment is supportive, including oxygen supplementation, mechanical ventilation, and steroids. [shmabstracts.com]
Treatment includes avoidance of, or protection from moist hay, especially with workers previously exposed who have had an infection. [oatext.com]
Prognosis

Prognosis Overall, the long-term prognosis is good for patients who survive the initial exposure to nitrogen dioxide (NO 2 ). Some cases of NO 2 toxicity resolve with no persistent or delayed symptoms. [emedicine.medscape.com]

Prevention
Treatment Corticosteroids such as prednisone or methylprednisolone help prevent lung injury in patients exposed to silage gases. [medical-dictionary.thefreedictionary.com]
Take steps to prevent silo-filler’s disease when working around upright or horizontal silos and silage bags. Discuss this information with family members and employees now and take action to prevent silo-filler’s disease. [fyi.uwex.edu]
