Pulmonary medicine expert witnesses are valuable educators to attorneys and other legal professionals. They are board-certified and experienced to consult concerning the diagnosis and treatment of diseases of the respiratory tract, including the trachea, bronchi, and lungs. These professionals may provide reports about asthma, COPD, emphysema, respiratory failure, pneumonia, coronavirus, COVID-19, pulmonary embolism, and lung cancer. They are competent in intensive care, pediatric pulmonology, and mechanical ventilation, among others. A pulmonary medicine expert witness may also testify in case of misdiagnosis, failure to diagnose, and complications of ventilator management.
