Lung function test in advanced age

Advanced age is not an obstacle to carring out a lung function test. In most cases a lung function test is necessary due to the fact that about 20% of older persons are affected by an obstructive respiratory disorder. Standard values for the lung function test are available up to advanced ages. The experience of the examiner and a calm environment for the lung function test have an impact on the quality of the measurement results. Severe cognitive impairments and severe immobility make the performance of a lung function test impossible. Simple geriatric assessments can help to reliably identify these patients. Alternative lung function test procedures have to be validated in order to adequately diagnose this vulnerable subgroup of patients at risk.
