2-TOPSHIRIQ
TOMCHINING TUSHISH TEZLIGI
Tomirga tomchi-dori quyish
amaliyotidan tibbiyotda bemor tomiriga
suyuqliklarni yuborishda foydalaniladi.
Hamshira tomchi-dori tushish tezligi ( D ) ni o‘lchash uchun har daqiqada qancha
tomchi tushayotganini hisobga olishi lozim.
Bunda hamshiralar
formuladan foydalanadi.
Formuladagi:
k – “hajm birligidagi tomchi miqdori” ko‘rsatkichi, 1 millilitrda tomchilar soni
o‘lchanadi.
V – dorining millilitrdagi hajmi;
n – tomchi tomib tugashi uchun ketadigan vaqt .
1-savol:
Hamshira tomirga dorini yuborish uchun sarflanadigan vaqtni ikki martaga
oshirmoqchi.
Agar formuladagi n ikki martaga oshirilsa, ammo k va V o‘zgarmasa, D qanday
o‘zgarishini tushuntiring.
