Orthostatic Hypotension in Older Adults: Measurement, Mobility and Escalation

Clinical framework

Orthostatic hypotension is commonly defined as a sustained fall of at least 20 mmHg systolic or 10 mmHg diastolic within three minutes of standing. It may contribute to light-headedness, weakness, syncope and falls, but symptoms have multiple possible causes.

Contributors include medication effects, dehydration, acute illness, autonomic dysfunction, anemia and cardiovascular disease. Interpret readings alongside symptoms and the wider examination.

Safe measurement and assessment

• When appropriate and within local protocol, rest supine for about five minutes, record blood pressure and pulse, then assist the person to stand with guarding. Repeat at about one and three minutes and document symptoms and readings.
• If standing is unsafe, do not force the test; use a suitable modified protocol or seek assistance. Check cuff size and technique and note medication timing and relevant context.
• Assess transfers, gait, balance, falls history, vision, footwear, aids and environment. Consider vestibular, cardiac, neurological and medication-related alternatives.

Mobility and escalation

• With presyncope, marked dizziness, chest pain, breathlessness or instability, stop the task, assist the person to sit or lie safely and follow local escalation procedures.
• Use staged position changes, pauses at the bed edge and supervised transfers while symptoms are investigated. Coordinate medication review with the medical team; do not independently advise extra salt or fluid when cardiac or renal conditions may make this unsafe.
• Urgent assessment is needed for syncope with concerning features, chest pain, new focal neurological deficit, severe breathlessness or persistent instability.

Rehabilitation and summary

• Once medically stable, address functional contributors with individualized strength, balance, gait and transfer practice while monitoring symptoms and postural response.
• Progress from supported positions to more demanding mobility only when symptoms and assistance needs permit. Track falls/near-falls, symptom frequency, transfer assistance and walking capacity.
• A single normal reading does not exclude cardiovascular causes. Measure consistently, connect readings with symptoms and coordinate review before increasing activity.
