how to calculate Kg without calculator from lbs
simply divided by 2 and subtract 10%.
Lidocaine 1% means
10mg /ml
Lidocaine 2% means

How do you calculate the percentage of gas being administered when 2 or 3 gases are being administered?
% of gas = (L) of the gas / Total amount of (L) administered x 100
What is the percent of oxygen in Air
21%
When you calculate flow of O2 in flow of medical air you must
first calculate the percentage of O2 out of the flow of medical air (21% of (x) L of air ) then proceed with other calculation.
Given a full cylinder contains 660L O2 @ 2000psi, How long can O2 flows of 2L/min be maintained if the bourdon pressure gauge reads 1000psi?
165 min
** General formula for E-cylinder calculation
Duration of Flow = Oxygen Tank CONVERSION FACTOR
x Remaining Tank Pressure (psi) / Continuous Flow Rate (L/min).
What is the CONVERSION FACTOR OF Esize tank
0.28
Estimated Blood Volume (EBV), these values are calculated based upon: SWA; the formula is
EBV?
Age, Sex, Weight; EBV = body wt (kg) x average blood volume (ABV) (ml/kg)
What are the Average BLOOD VOLUME (ABV) for (WoMINP) starts 65 add 10, add 5 2x +11 Women Men Infants Neonates Premature
65 75 80 85 96
How do you calculated EBV
Average blood volume x weight (kg)
How do you calculate ABL (Allowable Blood loss)
ABL = ((Original Hct - Final Hct)/ Original Hct) x EBV
What is the maintenance infusion rule
4 2 1
4* for first 10kg
2* for 2nd 10kg
1 for remainder kg
What is a significant figure?
is a digit in a measurement that has a physical meaning and can be reproducibly determined.
Accuracy refers to the
reproducibility of the measurement
Precision is the
reproducibility
The precision of a date set is improved
by averaging multiple measurements.
