How long will my cylinder last while using the MVP-10?
What size patient is the MVP-10 able to ventilate?
Why does my ventilator stop cycling when I increase my flow?
Do I need a Service Requisition Form to send a unit in for service?
How close to the MRI unit can I put the MVP-10?
This depends on several of factors, but mostly cylinder pressure and flow. The following formula may be used to calculate gas consumption for the MVP-10. The result will give you the minutes remaining (or full duration if the cylinder pressure reflects a full cylinder). For a comprehensive sheet (Acrobat Reader required) to print for your records, click here.
Cylinder Pressure x Factor(1) Patient Flow + 4 LPM(2) (1) Commonly used factors for cylinders (air or O2) D-CYL. E-CYL. G-CYL. H-CYL. M-CYL. .16 .28 2.41 3.14 1.56 (2) Average gas consumption of the pneumatic logic circuit in the MVP-10.
This is a question best answered by the medical professionals. The maximum calibrated tidal volume delivered by the MVP-10 is 660ml. This could be considered a determining factor.
This is caused by a restriction of some kind in the gas supply to the ventilator. Be sure you are not using a flow regulator to regulate your supply gas. These are too restrictive. They are unable to maintain the necessary pressure with the higher flows. Check for any fittings you may be using before the ventilator that may be restrictive. Remember, 50 PSI at the wall or cylinder doesn't always mean 50 PSI at the ventilator.
First and foremost, the MVP-10 must be compatible with a MRI environment. This will be indicated by a "MRI" plaque on top of the unit and a "M" at the end of the serial number. The ventilator should not be placed closer than one meter from the MRI. Click here if you would like a statement to that effect.
