Respiratory disease is one of the leading causes of death and disability in the Unites States. With the emergence of COVID-19, therapists will be treating even greater numbers of clients with compromised lung function. As a result, rehabilitation professionals must be prepared to provide effective rehabilitation for their clients with respiratory deficits. This seminar will review the background and scope of respiratory illness especially as it relates to older adult populations. It will also introduce strategies for assessing and implementing treatment interventions designed for clients with compromised lung function across rehab settings. Finally, it will review reimbursement and documentation principles to ensure efficacy in this area by healthcare providers.
