Anthropometry (3d)

Biochemical Test/Blood or Serum

Parameter of Anthropometry Body Weight & Height (P201) Broca (WB) = BH (cm)-100 (P201) Body Mass Index for weight judgment(202)

BMI = BW(kg)/ BH(m)2 (202)

Heart & Lung Function

1 Pulse: 60-90/min(range)

Position: Radial artery on wrist

Equipmnt:

2 Blood pressure 科氏法（听诊法）

正常值： 90-120mmHg/60-80mmHg

准确测量的条件

3 Lung vital capacity

FLJ-A浮标式肺活量计

受试者夹鼻，在一次平静吸气之末，继续做一次最大限度的吸气。三通阀门与肺量计相通，描记 3 ～ 4 次呼吸曲线。根据呼吸曲线变化的高度，计算出潮气量、补吸气量、补呼气量和肺活量
