Catalog excerpts

Each BUSTER ICU Cage comes with an oxygen accessories kit (J-1057Q). 6 X Venturi - 1 of each colour green, red yellow, white, blue and a blank (no holes) Attach the blank Venturi (no holes) to one end of the oxygen tubing. This then attaches to the oxygen supply. Unscrew the top half of the nebuliser and add the chosen medication. Keep the nebuliser vertical whilst screwing back together. Attach the end of the oxygen tubing to the base of the nebuliser. Attach the top of the nebuliser to the vertical arm of the T piece Attach one of the horizontal arms of the T piece to the BUSTER ICU Cage. Close the other horizontal arm with the cap provided. Turn on the oxygen at sufficient flow rate to nebulise the chosen medication. Attach the appropriate coloured Venturi to the other end of the oxygen tubing. Attach the Venturi to the vertical arm of the T piece. Push one of the horizontal arms of the T piece into the port on the BUSTER ICU Cage. Close the other arm of the T piece with the cap provided. Turn on the oxygen to the appropriate flow rate. The minimum oxygen flow rate is 2 litres per minute. Jorgensen Laboratories • 1450 N.

Rationale for Controlled Oxygen Therapy Excess oxygen can be harmful. Like many drugs, oxygen can be associated with toxicity and excess oxygen can be harmful to lungs (pulmonary endothelium). The use of inspired oxygen greater than 60% should be avoided if possible. Decreasing the amount of supplemented oxygen at the earliest possible time should be routine practice. The Venturi works in a similar fashion to a carbureter in a car engine. Oxygen is delivered into the Venturi barrel. As the oxygen passes through the barrel it draws in a calculated amount of air which mixes with the oxygen....

Calculating Total Gas Mixture Flow Rates The approximate volume of each BUSTER ICU Cage is as follows: Small 50 litres, Medium 120 litres and Large 460 litres. Select the Venturi for the condition using Diagram 1. Run the flow rates high initially to fill the ICU cage with oxygen enriched air at the appropriate concentration. Calculate minute tidal volume (1 Oml/kg x breaths per minute). Aim to change at least twice the minute tidal volume of air/oxygen mixture per minute. Calculate the oxygen flow rate using the chart below.

At the minimum 02 flow rate of 2 litres/min, this Venturi will generate a total flow rate of 52 litres/min. To calculate the total flow rate from the same Venturi if 02 flow is increased to say 4 litres/min, simply look for 4 litres/min on the vertical axis of the graph and follow the horizontal line unit it intersects the 24% line. At this point of the intersection look to see what air flow rate on the horizontal axis is appropriate. In this case it is 100 litres/min. Add the 02 flow rate for the final mixture flow rate. 100 (air entrained) + 4 (oxygen flow) = 104 litres/min. Similar...
