ANERIOD SPHYGMOMANOMETER

Aneroid Sphygmomanometer An aneroid sphygmomanometer is a manual, non-digital blood pressure measuring device used to measure systolic and diastolic blood pressure. Unlike mercury models, it uses a mechanical dial (aneroid gauge). The cuff is inflated manually with a bulb, and a stethoscope is normally used to listen for Korotkoff sounds while the pressure is released.      Main features Measurement type: Manual / auscultatory Gauge type: Aneroid mechanical dial Typical measuring range: 0–300 mmHg Typical accuracy: ±3 mmHg for quality clinical models Inflation: Manual bulb Deflation: Manual air-release valve Power: No batteries or electricity required Cuff: Usually nylon, reusable, and available in different sizes Stethoscope: Required for traditional auscultatory measurement Latex-free options: Available Use: Hospitals, clinics, physician offices, nursing/EMS training, and home manual BP measurement     Cuff size Approx. arm circumference Typical use Infant 6–11 cm Infants Child 10–19 cm Children Small Adult 18–26 cm Small arms Adult 25–35 cm Most adults Large Adult 33–47 cm Larger arms
