FAQ nitrous oxide sedation: Baldus Touch - Nitrous oxide sedation procedure

The stand-by button is located to the right of the display. To switch the device to stand-by mode, please press and hold the stand-by button for 3 seconds. When you turn on the device, the device performs a self-test. In our main menu you have two different options. Start the sedation once anonymously or with a patient ID. We start by entering a patient ID. A menu with letters and numbers opens; thus a patient can be created with name or patient number. After you have clicked on Enter, the sedation starts directly with a total flow of 5l/min and 0% N2O (=100% O2). In the case of "anonymous sedation" without storing a patient ID, the sedation display is shown. The sedation starts immediately with 5l/min and 0% N2O (=100% O2). The treatment time as well as the date and time are shown on the display below. At the top right you can see the total flow, i.e. how many liters of gas mixture the device emits per minute. The total flow is approximately determined based on the size of the patient. Then the sedation begins. During the entire sedation, the patient's vital signs are to be monitored using our pulse oximeter. During sedation, please always ensure that the breathing bag is filled with a sufficient gas mixture. In the example video you can see that you can administer a maximum of 70% nitrous oxide to the patient. This ensures that the patient is always supplied with enough oxygen.
GOOD TO KNOW: The mixer is used to add a percentage of medical nitrous oxide to medical oxygen. The patient remains conscious but becomes more relaxed and less anxious about the treatment. According to various specialist books and studies, nitrous oxide sedation up to a maximum of 70% nitrous oxide is minimal sedation with the aim of anxiolysis (solving anxiety) in the patient. It is not an anesthetic, the patient is awake, breathing independently and is able to react to external stimuli. In some patients, the sedative effect of 50% nitrous oxide is not sufficient. For this reason, in addition to the Baldus® Touch 50 device, which can administer a maximum of 50% nitrous oxide, there are also the Baldus® Touch 60 and 70 devices, which can administer a maximum of 60% and 70% nitrous oxide are limited. In this way, the trained user can decide for himself which maximum dose of nitrous oxide he would like to work with. The nitrous oxide concentration is individually tailored to the patient. The Baldus ® Touch 50, 60 and 70 variant is a built-in variant which can be used e.g. B. can be installed in the Baldus® All-in-One-Cart or in a plasterboard wall.

With the help of the O2 flush function, you always have the option of administering 50 to 60 liters of oxygen to the patient.

After the treatment, you can use the "Drain sedation' stop the sedation. The patient immediately gets 100% oxygen at the total flow you have issued. This recovery phase lasts 5 minutes, which you can also track on the display.

FAQ nitrous oxide sedation: How do I properly bleed the Baldus Touch?

In the video we show you how to bleed the Baldus Touch. First, anonymous sedation is started. Then we enter the maximum N2O concentration at any total flow. Now the blue nitrous oxide bottle is first turned clockwise. We can observe how the pressure reducer is now slowly falling. The "Error message" Check N2O gas supply now appears on the screen, as is acknowledged.

Next, the oxygen cylinder is turned off clockwise. Here, too, we can observe how the pressure gauge drops and the "error message" Check O2 gas supply appears on the display, which is also acknowledged. The entire system is now bled. Now you can either put the device into stand-by mode or press and hold the on/off button for about 7 seconds until the red light goes out and the system is shut down.

FAQ nitrous oxide sedation: How does sedation work with the Baldus Analog?

With the right rotary control you can adjust the flow. Laughing gas is added via the left rotary control. Up to a maximum concentration of 70%. The Baldus Analog is also available as Baldus Analog 50 and Baldus Analog 60 which are limited to a maximum of 50% and 60% respectively.

Please pay attention to the knobs, these EASY to move and not to overdrive. With the O2 flush function on the Baldus analog (see video), you can immediately administer 50 to 60 liters of pure oxygen to the patient.

FAQ nitrous oxide sedation: How do I connect the vacuum control block?

The suction and our vacuum control block: You can connect our control block to both the small and the large chair suction. If necessary, our adapter can also be used in both cases.

In any case, the vacuum control block should be adjusted using the rotary control so that the bead "flies" in the middle. You have now optimally adjusted the suction. This is also illustrated in the video:

FAQ nitrous oxide sedation: How do I assemble the scavenger system?

This video is about the hose system - ours Baldu's scavenger system and how this is put together. You start with the breath bag. This is attached to the lower end of the BAG-T.  Now the corrugated hose is connected to the double hose with the help of the connector.

Then the free end of the corrugated hose is plugged into the front outlet of the BAG-T. Now the suction hose is assembled. The package contains a longer and a shorter hose. Now the vacuum control block needs to be placed in the right direction between the 2 hoses. The shorter hose is placed on the designation “VAC” (pronounced suction). The longer hose is attached to the part of the vacuum control block where "MASK" is written.

Now the free end of the longer hose is attached to the double hose. Last but not least, you can put the hanger on the vacuum hose so that you can hang it anywhere. Then the suction hose can be connected to the chair suction.

In the video, our technician shows how easy it is to install the Baldus Scavenger system.

The Baldus Scavenger System / Purpose

That Baldus® double mask system was developed to reduce indoor air pollution from nitrous oxide and to protect personnel. The oxygen-nitrous oxide mixture is fed into the patient's inner mask via the spiral hose and the patient breathes in the gas mixture. When you exhale, a membrane opens and the gas is vented through the outer mask and vacuum hose.

Because the patient's breathing is decoupled from the suction, he gets more comfortable air. Thanks to the perfect fit and the soft material, the mask adapts to every face shape. The outer mask has the function of a vacuum bell, that is, it sucks the micro-leakage z. B. caused by a mustache, efficiently.

FAQ nitrous oxide sedation: Tips and tricks nitrous oxide pressure reducer

The pressure reducers are checked during annual maintenance and all seals are replaced. We have different thread sizes to accommodate these can never be interchanged. On the left side you can see the N2O pressure reducer in the video and on the right side the O2 pressure reducer. It is important to pay attention to the N2O seal before changing the bottle let it rest for at least 10 minutes because it expands a lot.

FAQ nitrous oxide sedation: How do I change the gas bottle?

This video is about the correct gas bottle change. For this you need the oxygen and nitrous oxide bottles shown in the video. The gas cylinders are provided with protective caps for transport. The first step is to unscrew the caps. The pressure reducers are then also turned on the gas cylinders on the connection provided. The nitrous oxide pressure reducer with the small thread, the oxygen pressure reducer with the large thread. It is important to only screw on both pressure reducers hand-tight. Both gas bottles are now placed in the car. On the right side oxygen, on the left side the nitrous oxide. Both bottles are secured with the belt against tipping over. The pressure hoses are then connected to the gas cylinders. Be sure to pay attention to the color coding. The blue pressure hose goes to the blue nitrous oxide bottle, the white pressure hose to the white oxygen bottle. To shoot, both wrongs are turned counterclockwise.

FAQ nitrous oxide sedation: When is the gas bottle empty?

This video is about how full the gas cylinders are and when it's time to get new ones to order gas cylinders. A full oxygen bottle has 200 bar. You can always read the filling level of the gas bottle on the pressure reducer. A full nitrous oxide bottle has 50 bar. Nitrous oxide is a liquid gas. Therefore, the filling level of the nitrous oxide cylinder cannot be read off the pressure reducer.

A full bottle gives you approximately 600 minutes of treatment time. As soon as the display on the pressure reducer has reached the red mark, you still have approx. 100 minutes of treatment time. Now it's time to get a new gas bottle. We recommend that you always keep at least one nitrous oxide bottle in reserve.  

How do I put the double nasal mask together?

This video is about assembling the double nose mask. Here you can see the inner mask. Before and after cleaning and during sedation, it is important to ensure that the membrane is correctly positioned on the mask. Here you can see the small pin on which you can attach the membrane. When inserting the inner mask into the outer mask, it is important that you hold the mask by the reinforced ends and not in the centre. You will then hear a soft click when it is inserted correctly.
