Ideal Body Weight (IBW), Adjusted Body Weight (ABW)

Formula:

IBW (kgs) = 22 x (height in meters)2
ABW = IBW + 0.4( actual weight - IBW )

In obese patients, where actual body weight is >30% over calculated IBW, an Adjusted Body Weight (ABW) is often recommended for drug dosing.

Blood Volume for Male, Female Body

Nadler's Formula:

For Males = 0.3669 * Ht in M3 + 0.03219 * Wt in kgs + 0.6041
For Females = 0.3561 * Ht in M3 + 0.03308 x Wt in kgs + 0.1833

Note:
* Ht in M = Height in Meters, which is then cubed
* Wt in kgs = Body weight in kilograms

Related Calculator:

Blood Alcohol Content Level

Formula:

Based upon % Ethanol:

[Males] AC = (BAC * BW)/(1.22* % Ethanol)
[Females] AC = (BAC * BW)/(1.51* % Ethanol)


Based upon Proof:

[Males] AC = (BAC* BW)/(0.61 * proof)
[Females] AC = (BAC * BW)/(0.75 * proof)


Time factor:

Added to this is 20 mg/dL/hr x hrs since ethanol is consumed.


Where,

AC - Alcohol consumption
BAC - Blood alcohol concentration / level in mg/dL
BW - Body weight in kg.

Serum Ascites Albumin Gradient (SAAG)

Formula:


SAAG (g/dL) = Serum Albumin - Ascites Albumin

Where

1. A SAAG >= 1.1 suggests presence of portal hypertension in patients with a transudative ascites.
2. A SAAG < 1.1 suggests absence of significant portal hypertension in patients with exudate ascites.

Assesses adequacy of compensation for metabolic acidosis
If calculated PaCO2 = actual PaCO2, then compensation adequate.
If actual > calculated, then both met and resp acidosis present.
If actual < calculated, then met acidosis & resp alkalosis present.
