Blood Pressure Measure Karne Ka Tarika
-
Sphygmomanometer Ka Use: Yeh ek inflatable cuff hai jo arm ke around wrap hota hai. Jab pump se air bhara jaata hai, cuff pressure build hota hai.
-
Pressure Ko Release Karna: Jaise hi air release hoti hai, cuff ka pressure arteries pe kam hone lagta hai. Is waqt, ek stethoscope se artery ki sound sunni jaati hai.
-
Systolic Aur Diastolic Readings: Jab sound pehli baar sunayi deta hai, wo systolic pressure hota hai. Jab sound band hota hai, wo diastolic pressure hota hai.
Physics Ka Role Blood Pressure Measurement Mein
Blood pressure ko samajhne ke liye kuch physics principles important hai:
-
Fluid Dynamics: Blood ek fluid hai, aur jab yeh arteries mein flow karta hai, toh iski movement aur pressure different factors se depend karti hai, jaise artery ka diameter aur blood viscosity.
-
Hydrostatic Pressure: Jaise cuff ke andar pressure increase hota hai, keha layers of tissues ke against force lagta hai, jo arteries mein blood ka flow disrupt karta hai.
-
Pressure Transducers: Modern blood pressure devices mein pressure transducers ka use hota hai, jo pressure changes ko accurately measure karte hain.
Real Cost/Time Table
| Device Type | Cost (INR) | Measurement Time | Notes |
|---|---|---|---|
| Manual Sphygmomanometer | ₹500 - ₹1500 | 2-3 minutes | Requires practice to use |
| Digital Blood Pressure Monitor | ₹1500 - ₹5000 | 1-2 minutes | Auto-measurement, easy to use |
