How to use a nebulizer correctly: step-by-step instructions and common mistakes

Nebulizer therapy makes it possible to deliver a medicine directly to the airways in the form of an aerosol. However, the effectiveness of the procedure depends not only on the prescribed medicine, but also on correct device assembly, breathing technique, and compliance with the rules for using the nebulizer.

In this article, we will review how to perform inhalations correctly, which mistakes should be avoided, and what to check if the nebulizer has stopped producing aerosol.

Preparation for the procedure: how to assemble the nebulizer and prepare the solution

Before starting the inhalation, read the instructions and make sure you fully understand how to use the inhaler.

It is important to prepare the device correctly, because stable aerosol formation depends on airtight connections and clean components. It is equally important to follow the specified safety rules, since a nebulizer is an electrical device, and incorrect use may cause injury and damage to the equipment.

What to check before use

• the cleanliness of the nebulizer chamber, mask, or mouthpiece
• the integrity of the air tube
• the correct connection of all components
• the presence and volume of the medicinal solution

How to assemble the nebulizer

• fill the chamber with the solution in the recommended volume
• connect the air tube to the compressor and the nebulizer chamber
• attach the mask or mouthpiece
• check that all connections are tight before switching the device on

Incorrect assembly or loose connections may lead to reduced nebulization efficiency or no nebulization at all, so it is very important to follow the instructions supplied with the device.

Preparing the solution

Solution for inhalation is prepared only from medicines prescribed by a doctor, following the recommended volume and concentration. If provided for in the treatment regimen, isotonic solution may be used as the base.

It is important not to exceed the maximum volume of the nebulizer chamber, because some liquid always remains inside as residual volume and is not nebulized during inhalation.

Step-by-step instructions: how to breathe correctly during inhalation

After preparing the nebulizer, it is important to perform the procedure correctly, because the breathing technique directly affects how the aerosol enters the airways and how effective the inhalation will be.

Body position, breathing rhythm, and deep inhalation technique

The optimal position is sitting, with relaxed shoulders and the head slightly raised. The mask or mouthpiece should fit tightly to avoid aerosol loss. When using a mouthpiece, the inhalation is usually deeper because the aerosol is directed straight into the airways. A mask is used mainly when a mouthpiece cannot be used or is not recommended.

Step-by-step instructions:

1. Assemble the nebulizer according to the instructions and check the airtightness of the connections.
2. Sit in a comfortable position with your back straight and your shoulders relaxed.
3. Put on the mask or use the mouthpiece, ensuring a tight fit.
4. Start breathing calmly and evenly.
5. Take a slow, deep breath through the mouth, without sudden movements or breath-holding.
6. Exhale calmly, in a natural rhythm, without changing the pace of the procedure.
7. Continue inhalation until the solution in the chamber has finished nebulizing.

Features of inhalation in children: how to make the procedure safe

Inhalations in children require a particularly careful approach, because the effectiveness of the procedure is influenced by proper selection of the attachment, how tightly it fits, and calm breathing during inhalation.

Before inhalation, it is important to choose a mask of the appropriate size that fits the face closely without excessive pressure. This helps reduce aerosol loss and ensures delivery to the airways.

During the procedure, the child must be under constant adult supervision. Inhalation should be performed in a calm state, without crying or active movement, as this may disrupt the regular breathing cycle and reduce nebulization efficiency. If the child feels discomfort, the procedure should not be continued by force – it is better to pause and resume inhalation after the child calms down.

How long should inhalation last, and how can you tell that the solution has run out?

The duration of inhalation depends on the volume of the medicinal solution, the nebulization rate of the nebulizer, and the features of the specific model. In most cases, the procedure continues until the device stops producing a visible aerosol.

Signs that the inhalation is complete may include:

• a significant decrease or cessation of aerosol formation;
• a characteristic sound from the nearly empty nebulizer chamber;
• no noticeable decrease in the liquid level in the chamber.

It is important to keep in mind that after the procedure is completed, a small amount of liquid usually remains in the chamber. This is the so-called residual volume – the part of the solution that the nebulizer design does not allow to be converted into aerosol. Its presence is a normal technical feature of the device and does not indicate malfunction or incorrect use of the nebulizer.

Typical mistakes that reduce treatment effectiveness

Even when the medicine is chosen correctly, the effectiveness of inhalation may decrease because of mistakes made during the procedure. Most often, they are related to breathing technique, the position of the nebulizer, or failure to follow operating rules.

Common mistakes include:

• talking during inhalation, which disrupts the regular breathing cycle;
• performing the procedure while lying down, unless otherwise recommended by a doctor;
• breathing too quickly or too shallowly;
• a loose fit of the mask on the face;
• excessive tilting of the nebulizer chamber, which changes the liquid level and may worsen aerosol formation;
• using dirty or damaged accessories;
• changing the prescribed volume or concentration of the medicine independently.

To make inhalation as effective as possible, it is important to follow the manufacturer’s recommendations for using the nebulizer and the doctor’s prescriptions for using medicines.

Hygiene after use: a brief overview of accessory care

After each inhalation, the accessories that came into contact with the medicinal solution or the airways must be cleaned according to the manufacturer’s instructions. Regular care helps prevent the accumulation of medicine residues and supports correct operation of the nebulizer chamber.

After completing the procedure, disassemble the nebulizer chamber, rinse the parts recommended for washing, and dry them before the next use. Particular attention should be paid to the mask, mouthpiece, and nebulizer chamber.

Before assembling the device after cleaning, all components must be completely dry. It is also important to regularly check the condition of the accessories and replace them in a timely manner if they are worn or damaged.

Approximate duration of inhalation depending on solution volume

Note: the calculation is based on the stated nebulization rate of ≥0.20 ml/min for the models Ulaizer Air+ and Ulaizer Home. The actual duration may vary depending on the medicine, conditions of use, and residual volume in the chamber.

Checklist: what to check if the nebulizer has stopped producing aerosol

If the nebulizer is switched on but aerosol is not being produced or has decreased significantly, several main causes should be checked step by step:

• whether the device is connected to a power source and whether the compressor is operating;
• whether the chamber, tube, and attachment are assembled correctly;
• whether there are any kinks or damage to the air tube;
• whether there is enough solution in the chamber;
• whether the nebulizer openings or other chamber components are dirty;
• whether all accessories are tightly connected;
• whether the parts show signs of wear or damage.

If, after checking these points, the nebulizer continues to operate incorrectly, you should contact a service center or review the manufacturer’s recommendations for diagnosing the specific model.

Questions and answers

How does a nebulizer work?
A nebulizer converts a medicinal solution into a fine aerosol using a compressor or an ultrasonic/mesh mechanism. In compressor models, an air flow passes through the chamber containing liquid, forming particles that the patient inhales through a mask or mouthpiece.

How should you breathe through an inhaler during the procedure?
During inhalation, you should sit with your back straight and breathe calmly and evenly. The breath in should be slow and deep through the mouth, without sudden movements or breath-holding, and the breath out should be natural and relaxed. This rhythm ensures even delivery of aerosol to the airways.

How long should you breathe through a nebulizer during one procedure?
The duration of inhalation is usually from 5 to 20-25 minutes and depends on the solution volume, nebulization rate, and device model. The procedure is performed until aerosol formation in the chamber has practically stopped.

What should you do if no “steam” comes out of the nebulizer?
A nebulizer produces aerosol, not steam. If aerosol is not being produced, check that the device is assembled correctly, the solution level in the chamber, the condition of the air tube, the cleanliness of the nebulizer, and the power supply. If the problem persists, contact a service center or check the manufacturer’s instructions.
