Term
Water Density
Definition
1gm/ml
Term
Calculating the Concentration of a solution
Definition

Multiply the concentration by 1000mL

 

Ex: 3% lidocaine

 

3% x 1000 ml = 30mg/mL 

Term
1:1000
Definition
1 mg/mL
Term

(degrees) 

Definition

C= 5/9(F-32)

 

 

 

Term

C to F conversion

 

(degrees) 

Definition
F= 9/5C + 32
Term

pH
Definition

pH is defined as a negative decimal logarithm of the hydrogen ion concentration in a solution 

 

If hydrogen concentration is a x 10-b 

 

then

 

pH= -log(a x 10-b)

Term

Definition

4:2:1 

 

4mL/kg/hr for the first 10 kg of body weight

2 mL/kg/hr for the second 10 kg of body weight 

1 mL/kg/hr for each kilogram of bodyweight thereafter
