FAQ - Emergency Care

Is the black Ambu Mark III Resuscitator made of Natural Rubber Latex?

No, except for the black cuff with the orange stopper of the transparent face mask that contains Natural Rubber Latex, all other rubber parts of the Ambu Mark III Resuscitator are made of the following rubber materials: EPDM, Chloroprene and Silicone rubber.

For an overview of all materials of the product parts please refer to the Ambu Directions for use of the individual product.

What is the use of the Ambu Mark III Resuscitator in polluted or toxic atmosphere characterized by? 

As to ventilation in polluted or toxic atmosphere the Ambu Mark III Resuscitator (with the gas filter adapter for attachment of various standard gas filters) offers considerably better protection against penetration of various gases compared to resuscitators made of Silicone rubber.

The standard Ambu Mark III Resuscitator has an outer cover made of Chloroprene rubber providing excellent protection. The special Ambu Mark III Resuscitator, however, has an outer cover made of Butyl rubber providing optimal protection.

Below is a table comparing penetration of selected gases in different rubber materials.

 

 Penetration of gases in vulcanized material in 10-9 cm2 x sec. -1 x at-1 at 80 degrees C
 
 Rubber basis  Oxygen  Nitrogen  Carbon dioxide
 Natural rubber  400 360  2,100 
 Chloroprene rubber(Ambu Mark III, standard model)  90 80  810
 Butyl rubber (Ambu Mark III, special model)  50 35  290 
 Silicone rubber   4,100  3,600  13,000
Source: Walter Null - Chemie und Technologie der Silicone, Chapter 9, p. 446.

The above table shows that:

1) Chloroprene rubber offers better protection against penetration of gases compared to Silicone rubber.

2) Butyl rubber offers even better protection.

PEEP ventilation - can you explain something about that?

Positive End-Expiratory Pressure (PEEP). PEEP ventilation is where a valve in the breathing circuit maintains a positive pressure in the lungs at the end of expiration. The purpose is to increase the volume of gas remaining in the lungs in order to improve gas exchange. It is an integral part of respiratory treatment in a considerable range of critically ill patients of any age. It is indicated especially when adequate oxygenation cannot be achieved by employing intermittent positive pressure ventilation with high oxygen concentration. It is also indicated when the oxygen transfer is extremely bad such as during cardiopulmonary (CPR) resuscitation with a circulation being maintained entirely artificially and during resuscitation of nearly drowned patients with considerable shunt.

The Ambu PEEP valve enables the trained operator to start PEEP ventilation during prehospital treatment and during transport of patients.

USB CONNECTION 
Q: The CPR software cannot find the manikin, what do I do?
A: The reason can be that the USB driver is not installed. Please install the USB driver and try again.

Q: Why is the ‘Ambu Controller’ not shown in the Device Manager under ‘Universal Serial Bus Controller’?
A: There can be two reasons for that. The first reason is that the USB driver is not installed. Please install the USB driver and try again. The second reason is that the USB port was change. Please connect the manikin to the USB port where the Interface originally was installed.

Q: My computer says that the USB hardware cannot be used. How do I get it to work?
A: Either another USB driver has overwritten the driver for the manikin and you need to install the USB Driver again. Or the USB port was change. Then you need to connect the manikin to the USB port where the Interface originally was installed.

Q: What does it mean if there is a yellow mark in front of the ‘Ambu Controller’ in the Device Manager under ‘Universal Serial Bus Controller’?
A: It means that either another USB Driver has overwritten the driver for the manikin or the USB port was change. Please reinstall the USB Driver, or connect the USB Interface to the USB port where the Interface was originally installed.

Q: What does it mean if the ‘Ambu Controller’ with a yellow mark in front is shown under ‘Other Devices’ in the Device Manager under ‘Universal Serial Bus Controller’?
A: It means that windows has deleted the drives for the USB Interface. You need to reinstall the USB Driver.

Q: What do I do, if I don’t have an entry ‘Ambu AMC Box’ in the Device Manager under “Ports”?
A: It means that another USB Driver has overwritten the driver for the USB Interface and you need to reinstall the USB Driver.

Q: Does the new CPR Software version work with the old manikins?
A: Yes, the new CPR Software is backward compatible with the old manikins. You can use the USB hub for the connection

Q: Can I use the USB at the same time as the batteries are inside?
A: Yes it will mainly run on the USB and only use the batteries if required

 

WLAN CONNECTION
Q: I can’t establish a wireless connection, what can I do to get it to work?
A: There can be more reasons for this. Maybe the manikin is not turned on, please check to see if this is the case, and if so, turn it on. Another reason can be that the WLAN card on the computer is turned off. Please turn on the WLAN card and try again.
It could also be that the network is not fully established. Wait for moment and search for the manikin again with the CPR Software.
If the settings on the manikin and the computer are not the same this could also be the reason. Please set the manikin and the computer to the same settings and see if that helps.
Lastly, it could be that the Firewall blocks the communication. Disable the firewall on the computer or change the settings to allow the CPR Software to use the WLAN Connection.

Q: Can I do anything if the wireless connection is unstable?
A: The reason for this could be that there is a high network traffic that may interrupt the WLAN connection. Switch to the USB connection or place the manikin in an environment with low wireless networks. If possible you can also set the manikin to an infrastructure network and use the managed network.

Q: What is the maximum distance I can run the manikin from?
A: The maximum distance to use the wireless functionality is 50 metes if you are outside

Q: What protocol is used?
A: The system uses the WLAN Protocol IEEE802.11 b/g.

Q: What encryption method can be used?
A: You can use WEP and WPA/WPA2 for encryption.

Q: What network topologies can be used
A: The system can work in ad-hoc or infrastructure mode. In both modes the Ip-address can be set manually or automatically by using DHCP.

 

ECG CONNECTION

Q: Is the physical ECG box included in the package?
A: No it is an accessory, but the software part of the ECG Box is integrated in the CPR Software provided with Defib Man and Cardiac Care Man

Q: What do I do if the text does not fit the buttons?
A: The font for the box is not installed correctly. Try to restart the computer after the installation.

Q: Why can’t I see the ECG Signal?
A: One of the reasons this could be is that a manikin without ECG Signal is used. Try to connect an Ambu Defib Trainer or an Ambu Cardiac Care Trainer and see if the signal is there.
Another reason could be that the cable is not attached properly. Lift the skin on the left shoulder of the manikin and check if both plugs are connected correctly.
Last reason could be that the ECG Signal is disabled in the software. You need to open the configuration menu in the CPR software and unmark the field ‘show ECG Signal’. In the main window you need to unmark the field ‘ECG Signal’.

Q: Why can’t I feel the pulse on the manikin?
A: If a pulse-less signal is chosen this could be the reason for why it’s not working. Chose a signal on the ECG Box, which has a pulse activity.
Check to see if the pulse is turned off on the ECG Box. If so activate it, and you should be able to feel the pulse.
Another reason could be that there is no power supply turned on. Insert batteries or attached the manikin to the optional AC/DC Adaptor.
If the manikin is powered on USB the pulse will not work. Please insert batteries or attached the manikin to the optional AC/DC adaptor.

Q: What does 3/4 or 3-4 lead ECG means?
A: 3 lead ECG means, that you take the standard ECG according to Einthoven (I, II, III) or according to Goldberger (aVL, aVR, aVF). Transthoracic interpretation of the electrical activity of the heart detected by 3 lead, which means monitoring the activity from 3 different angles, please see illustration below.(might not be relevant)

Q: Can you choose between 3 or 4 leads and is this standard?
A: In our Manikins you can only take the ECG according to Einthoven I and III.
The 4. ECG-Elektrode is a neutral electrode you can use, but you don't have to.
The general way of making an ECG (especially in EMS) is using a 3-lead ECG

Q: What do I do if I can’t see the ECG signal on the defibrillator, but I can see it on the computer?
A: Make sure the ECG connectors are mounted correctly. Red on Right, Yellow on Left and Green/black on left abdomen. 

ECG Mount

 

Q: Why is there no ECG signal on the CPR software when connected to the Ambu Man W
A: If you want to use the ECG Signal you have to connect it to either Cardiac Care or Defib Man, as it is these manikins where ECG can be trained. Ambu Man W is not designed for defibrillation

CPR SOFTWARE

Q: Can I use older Version of the CPR Software with the wireless manikin?
A: No, the old Software version does not work with the wireless manikins.

Q: Does the new CPR Software version work with the old manikins?
A: Yes, the new CPR Software is backward compatible with the old manikins. You can use the USB hub for the connection

Q: Why is there a time delay in the software?
A: The time delay in the software can happen due to the wireless transmission. When data is sent through radio transmission the timing between the transmitter and the receiver is important. If a lot of traffic is around, the time for the transmission can increase. The CPR Software therefore holds the screen and waits for the data transmission. The CPR Software buffers with this function the time and assures that no data is lost.

Q: Why are the Manikin in the software numbers so funny and way are there no system?
A: The computer selects the Com port the manikin is using automatically, and it is individual how many ports the computer has. If you use a USB hub the numbers might be even higher.

Q: What if nothing works, I’ve changed something that I can’t remember any more
A: you can always press the reset button on the manikin and or on the software “ reset to defaults”

UPDATES

Q: Can I upgrade an old manikin to a wireless manikin?
A: No, it is not possible to update an old manikin.
Q: Can I update an AmbuMan Wireless to a Defib Man Wireless if I decide to do so later
A: We do not recommend doing so, as it will be a major intervention and it has to be done by an Ambu repair specialist. The price will therefore almost be the same as if you bought a Defib Man Wireless manikin.
Q: Can I change the print my self?
A: No it is a service part and a Ambu trained service centre has to change it

VENTILATION QUESTIONS

Q: Can I use a rescue mask on the Airway Man and Cardiac Care?
A: Yes, both the Airway Man and Cardiac Care Trainer are meant for Bag Ventilation. But as described in the DFU the manikins should not be ventilated by mouth-to-mouth or mouth-to-nose, so the ResCue Mask should only be used together with a resuscitator.

Q: Is the filter in the rescue mask sufficient to be hygienic correct?
A: The filter of the ResCue mask does not have a 100% filtration, so there will be a contamination of the airway of the manikin.
As the manikins are not made for replacement of the airway or parts of the airway, ventilation with an Ambu ResCue mask or similar products from other Manufacturers should not be done.
