To find the number of milligrams in a millilitre you need to divide 500mg by 100; 1ml of 0.5% lidocaine contains 5mg per ml.

Intravenous Administration: The initial starting dose is 0.2 to 1 mg every 2 to 3 hours. Intravenous administration should be given slowly, over at least 2 to 3 minutes, depending on the dose. The initial dose should be reduced in the elderly or debilitated and may be lowered to 0.2 mg.

A basic formula, solving for x, guides us in the setting up of an equation: D/H x Q = x, or Desired dose (amount) = ordered Dose amount/amount on Hand x Quantity….Dimensional Analysis Method

1. The clinician has 2 mg/mL vials in the automated dispensing unit.
2. How many milliliters are needed to arrive at an ordered dose?

How many mg per mL will be infused for a solution of 550mg of a medication in 200mL of saline? 2.75 → 2.8mg/mL or 3mg/mL Page 6 Sheet 2 1 A patient needs 2g of a medication.

Drip Rates — is when the infusion volume is calculated into drops. The formula for the Drip Rate: Drip Rate = Volume (mL) Time (h) . A patient is ordered to receive 1 000 mL of intravenous fluids to run over 8 hours.

To calculate the drops per minute, the drop factor is needed. The formula for calculating the IV flow rate (drip rate) is total volume (in mL) divided by time (in min), multiplied by the drop factor (in gtts/mL), which equals the IV flow rate in gtts/min.

Reference Chart of Drops per Minute

In general, standard (macrodrip) administration sets have a drip factor of 10, 12, 15, or 20 gtt/ml (drops per milliliter). For a microdrip (minidrip) set, it’s 60 gtt/ml.

Q=Vt Q = V t , where V is the volume and t is the elapsed time. The SI unit for flow rate is m3/s, but a number of other units for Q are in common use. For example, the heart of a resting adult pumps blood at a rate of 5.00 liters per minute (L/min).

flow rate (mL/hr) = total volume (mL) ÷ infusion time (hr)

The easiest way to get a fairly accurate measure of your water flow rate is to time yourself filling up a bucket. So for example if you fill up a 10 litre bucket in 1.5 minutes, then your flow rate will be: 10/1.5 = 6.66 Litres per minute. Don’t get confused between flow rate and pressure.

Here is how to measure your water flow rate Take the amount of water in the jug in litres (e.g. 0.8 litres) and multiply this by 10. This will give you your flow rate in litres per minute (e.g. 0.8 litres x 10 = 8 litres per minute).

LPM is an abbreviation of litres per minute (l/min). When used in the context of a particle counter’s flow rate, it is a measurement of the velocity at which air flows into the sample probe. For example, a flow rate of 2.83 LPM means the particle counter will sample 2.83 litres of air per minute.

The standard liter per minute is a unit of volumetric flow rate of a gas at standard conditions for temperature and pressure, which is most commonly practiced in the United States whereas European practice revolves around the normal litre per minute.

oxygen flow rate

High-flow nasal cannula (HFNC) therapy is an oxygen supply system capable of delivering up to 100% humidified and heated oxygen at a flow rate of up to 60 liters per minute.

It is designed to deliver continuous oxygen therapy up to a maximum flow of 60 L/min. The AcuCare High Flow Nasal Cannula is for single-patient use (maximum seven days) in the hospital/clinical environment.

At 6 LPM, the approximate FiO2 is 56%. What percentage of oxygen is 10 LPM? At 6 LPM, the approximate FiO2 is 60%. Every increase by 1 LPM equates to a 4% increase in FiO2, starting from 24%.
