mL per Hour र Drops per Minute

🧠 यो किन महत्त्वपूर्ण छ

PUMP का लागि: mL/hr = जम्मा आयतन ÷ जम्मा घण्टा। 8 घण्टामा 1,000 mL = 125 mL/hr। समय मिनेटमा छ भने रूपान्तरण गर्नुहोस्: 30 मिनेटमा 250 mL = 250 ÷ 0.5 = 500 mL/hr। GRAVITY set का लागि: gtt/min = (mL मा आयतन × gtt/mL मा drop factor) ÷ मिनेटमा समय। Drop factor tubing मा छापिएको हुन्छ: macrodrip set सामान्यतया 10, 15 वा 20 gtt/mL हुन्छन्; microdrip set 60 gtt/mL हुन्छन्। 8 घण्टामा 1,000 mL, 15 gtt/mL set सहित: (1,000 × 15) ÷ 480 min = 31.25, round गर्दा 31 gtt/min। Microdrip set मा gtt/min सधैं mL/hr बराबर हुन्छ, किनभने 60 gtt/mL ÷ 60 min कटिन्छ। थोपालाई सधैं पूर्णांकमा round गर्नुहोस्। DOSE-BASED infusion का लागि, पहिले प्रति घण्टा डोज खोज्नुहोस्, त्यसपछि mL/hr: 250 mL मा 25,000 units को heparin 1,000 units/hr मा चलाउनुपर्दा 100 units/mL हो, त्यसैले 1,000 ÷ 100 = 10 mL/hr।

For a PUMP: mL/hr = total volume ÷ total hours. 1,000 mL over 8 hours = 125 mL/hr. If the time is in minutes, convert: 250 mL over 30 minutes = 250 ÷ 0.5 = 500 mL/hr. For a GRAVITY set: gtt/min = (volume in mL × drop factor in gtt/mL) ÷ time in minutes. The drop factor is printed on the tubing: macrodrip sets are commonly 10, 15 or 20 gtt/mL; microdrip sets are 60 gtt/mL. 1,000 mL over 8 hours with a 15 gtt/mL set: (1,000 × 15) ÷ 480 min = 31.25, rounded to 31 gtt/min. With a microdrip set, gtt/min always equals mL/hr, because 60 gtt/mL ÷ 60 min cancels. Always round drops to a whole number. For a DOSE-BASED infusion, first find the dose per hour, then the mL/hr: heparin 25,000 units in 250 mL to run at 1,000 units/hr is 100 units/mL, so 1,000 ÷ 100 = 10 mL/hr.

🏥 वास्तविक जीवनमा

🔢 Order: 20 gtt/mL tubing सहित gravity बाट 4 घण्टामा 500 mL normal saline। (500 × 20) ÷ 240 = 41.7, त्यसैले प्रति मिनेट 42 थोपा। नर्सले एक पूरा मिनेट थोपा गन्छ र roller clamp मिलाउँछ। परीक्षामा समय प्रायः घण्टामा दिइन्छ र सूत्रलाई मिनेट चाहिन्छ; त्यो रूपान्तरण नै जाल हो।

🔢 Order: 500 mL of normal saline over 4 hours by gravity with 20 gtt/mL tubing. (500 × 20) ÷ 240 = 41.7, so 42 drops per minute. The nurse counts drops for a full minute and adjusts the roller clamp. On the exam, the time will often be given in hours and the formula needs minutes; that conversion is the trap.
