Contraindications
CAUTION: Dopplex Ability provides just one indicator of vascular
condition. This should be used as part of an holistic approach to
leg ulcer assessment together with other factors in forming the
clinical diagnosis. The results from dopplex Ability must not be
solely relied upon. A complete vascular assessment including
clinical history and symptoms must be made before taking
appropriate action.
CAUTION: If the results from the dopplex Ability do not match the
clinical history and symptoms of the patient, then further tests,
e.g. Doppler waveform analysis, are recommended.
WARNING: Dopplex Ability is not intended to be used in the
following patient conditions:
• a suspected or present Deep Vein Thrombosis (DVT)
• severe congestive cardiac failure or similar condition
• gangrene
• recent skin graft
• untreated leg or foot wounds
• dermatitis
CAUTION: Dopplex Ability is not intended to be used in the
following patient conditions:
• cellulitis
• management of pulmonary hypertension
• patients who cannot remain still or lie fl at
• patients under 18 years of age
• Severe hypertension
• Parkinsons Disease
• Severe PAD (ankle systolic pressure less than 60 mmHg)
• Lymphoedema
• Very oedematous limbs
• Any condition that prevents both arm pressures being
measured e.g. mastectomy
CAUTION: False high ABI results may occur in diabetic patients
when the leg cuff is unable to compress calcifi ed distal arteries
on the ankle effectively.
CAUTION: Ensure all cuffs are fi tted correctly and aligned on
limbs according to the instructions. Measurement error may
occur if cuffs are fi tted incorrectly.
