IC-2A FAQs

How long will my cylinder last while using the  IC-2A?

How small a patient can I ventilate using the IC-2A?

I hear a leak inside my IC-2A even when it is turned off. Is this normal?

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 IC-2A?

How can I monitor for disconnect during a MRI session?

 

How long will my cylinder last while using the  IC-2A?

This depends on several factors, but mostly cylinder pressure and tidal volume. The following formula may be used to calculate gas consumption for these ventilators. 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.

The IC-2A is considered to be a pediatric through adult ventilator, but not infant. How small a patient can I ventilate using the IC-2A?

This is a question best answered by the medical professionals. The minimum calibrated tidal volume delivered by the IC-2A is 130ml. This could be considered a determining factor.

I hear a leak inside my IC-2A even when it is turned off. Is this normal?

A slight bleed is normal with the IC-2A turned off and both gas supplies connected. However, an audible bleed with only a gas source connected to the center logic supply fitting indicates a problem with the supply gas pressure. It is probably below 30 PSI which is below the specification for the ventilator.

Why does my ventilator stop cycling when I increase my flow?

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.

Do I need a Service Requisition Form to send a unit in for service?

Yes.  Download Service Requisition Form .

How close to the MRI unit can I put the IC-2A?

First and foremost, the IC-2A 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.

How can I monitor for disconnect during a MRI session?

You can use a pressure monitor such as our M-1 monitor.  It cannot be used in the MRI room, but many hospitals have one set up outside the room with a long tube that tee's into the airway pressure line on the breathing circuit where it connects to the IC-2A.  To tee into the circuit, we offer the 8006 tee.
