Performance Specifications

Patient Population

The Welch Allyn Spot Vital Signs is designed for use with adult and pediatric patients. Welch
Allyn defines a pediatric patient as 29 days old or more.
THE WELCH ALLYN SPOT VITAL SIGNS IS NOT INTENDED FOR USE ON NEONATES .
Welch Allyn defines neonates as children 28 days or less of age, born at term (37 weeks gesta-
tion or more), otherwise up to 44 gestational weeks.

Cuff Pressure Range

0 mmHg - 300mmHg

Initial Cuff Inflation

160 mmHg

Systolic Determination

Maximum: 250 mmHg
Minimum: 60 mmHg

Diastolic Determination

Maximum: 160 mmHg
Minimum: 30 mmHg

Blood Pressure Accuracy

Blood pressure accuracy meets or exceeds SP10-1992 AAMI standards for non-invasive blood
pressure accuracy (AAMI standard: ± 5 mmHg mean error, 8 mmHg standard deviation). Blood
pressure accuracy is validated for pressure measurement using the upper arm only.

Blood Pressure Determination Time

Typical: 20 to 45 seconds
Maximum: 165 seconds
