A drop in systolic blood pressure (BP) of at least 20 mmHg or a drop in diastolic BP of at least 10 mmHg within 3 minutes of standing from a supine or sitting position (Feldstein & Weder, 2012).
Orthostatic hypotension can increase the risk of falls, diminished function & decreased quality of life (Feldstein & Weder, 2012; Irvin & White, 2004; Lee, 2013; Ricci, De Caterina & Fedorowski, 2015; Lipsitz, 2017).
Orthostatic blood pressure measurements should be included in the assessment of all older adults (Lipsitz, 2017):
*Note, if the patient complains of dizziness or lightheadedness, refrain from asking them to stand.
