What is the role of nebulization in the treatment of obstructive airway diseases?
Use of nebulization at home should be considered as a part of the maintenance regimen for obstructive airway diseases for patients who were already on home nebulization or unable to use handheld inhalers
What is the process of nebulization?
Nebulization takes place as a result of the disruption of the liquid by the expanding vapour that is formed upon evaporation of part of the liquid in the tube. B. Vig, M. Morgen, in Developing Solid Oral Dosage Forms (Second Edition), 2017
What is the indication of nebulization therapy?
Indication. Nebulization therapy is used to deliver medications along the respiratory tract and is indicated to various respiratory problems and diseases such as: Bronchospasms. Chest tightness. Excessive and thick mucus secretions. Respiratory congestions. Pneumonia.
What is a nebulizer?
A nebulizer is a breathing machine used to treat asthma. The nebulizer converts a liquid medication, usually a bronchodilator like albuterol, into a mist that can be easily and painlessly inhaled. Nebulizers are frequently used in infants and young children who are unable to use inhalers on their own.

What is the process of nebulizing a tube?
Nebulization takes place as a result of the disruption of the liquid by the expanding vapour that is formed upon evaporation of part of the liquid in the tube.
How does a nebulizer work?
Nebulization involves using compressed air through a ‘nebulizer’ to convert liquid medications into a mist that can then be breathed in by the patient. Different nebulizers produce mists with differing particle sizes. The particle size produced is very important, because the larger the particles, the sooner they drop out of suspension in the mist and therefore the less far into the respiratory tract they are able to penetrate. Particles of 1–5 microns (μm) penetrate into the narrow branches of the lower airways. Rabbits have frequently been used as experimental models for nebulized medications and there is much evidence to support the fact that particles of known size penetrate into the lungs (Dijk et al., 1997; O’Callaghan et al., 1992). Nebulization is a good adjunctive therapy for rhinitis, sinusitis, bronchitis, pneumonia and other parenchymal lung diseases. Many compounds can be used in this manner, one significant advantage being that the risk of systemic side effects is lower than with oral or parenteral medication. Mucolytics (for example, bromhexine, N -acetyl l -cysteine), surfactants and agents that assist penetration into tissue (hyaluronidase) can be added to moisturizing agents such as saline as well as antibiotics, antifungals and even antiseptic compounds. Where the compound of interest is not very soluble in water, then propylene glycol can be added to aid solubility. Because nebulization has been used in avian medicine for many years there are many ‘recipes’ for nebulization liquids published ( Carpenter, 2012; Harrison and Lightfoot, 2008 ). These are not validated for use in rabbits, and often their effectiveness is anecdotal. Basing the choice of anti-infective on culture and sensitivity results, and choosing additional preparations such as mucolytics based on clinical signs, would seem a logical starting point. Most rabbits tolerate nebulization well, although if this therapy is delivered via an oxygen tent, care must be taken not to allow the rabbit to overheat. Nebulization should be done several times daily for 30-45 minutes.
Why use spray atomization model?
Spray atomization models may be used to provide understanding of the spray droplet size, typically an unmeasured process attribute ( Aliseda et al., 2008; Mueller and Kleinebudde, 2007; Müller and Kleinebudde, 2006; Tobiska and Kleinebudde, 2003 ). In turn, the drop size predictions can help to design the initial process or provide guidance for scale-up with reduced need for trial-and-error experiments. This section of the book chapter will show how a modeling approach can be used to select the atomization process conditions based on the formulation, process parameters, and equipment design.
Why is nebulization of extracts into a flame atomic absorption spectrometry impractic?
Direct nebulization of extracts into a flame atomic absorption spectrometry is impractical at low concentrations because the flame strongly absorbs radiation at the wavelengths of sensitive absorption lines. Better sensitivity is obtained by the hydride generation technique, in which arsenic (as arsine vapor) is introduced into a hydrogen–argon reducing flame or into a heated tube for measurement of atomic absorption.
Why is atomization condition selected?
Historically, the atomization condition was selected based on previous experience or vendor recommendation, but not adjusted systematically based on the actual formulation properties or equipment/process capability. Generally, adjustment would only be made if there were severe issues during initial development of the coating process or as part of range finding studies.
How small is a nebulizer?
A particle size of less than 3 μm is required in order to have a local effect in the lungs and air sacs. Several inexpensive nebulization units are available (Acorn II nebulizer, Marquest Medical) that produce suspended particles in the size range of 0.5–6 μm. Many commercial humidifiers and vaporizers do not produce particles this small. The parabronchi of birds range in size between 0.5 and 2 mm, and the air capillaries vary in size from 3 to 10 μm in diameter. Because the avian lung differs from that of mammals in that the air capillaries are not dead-end saccules, nebulization therapy can be an effective treatment ( Loudis & Sutherland-Smith 1994 ). However, if there is considerable airway congestion or lack of flow, this form of treatment may not reach the tissues needing it the most.
Can propylene glycol be used in nebulization?
Where the compound of interest is not very soluble in water, then propylene glycol can be added to aid solubility. Because nebulization has been used in avian medicine for many years there are many ‘recipes’ for nebulization liquids published ( Carpenter, 2012; Harrison and Lightfoot, 2008 ).
When to use a nebulizer?
Nebulizers are frequently used in infants and young children who are unable to use inhalers on their own. When a patient uses a nebulizer, a small mask is put over the face while the patient breathes normally. It is not necessary for patients to be able to hold their breaths or to inhale deeply in order to benefit from a nebulizer treatment. This is especially beneficial when the patient is a baby, a young child, or an elderly patient with dementia.
What is a nebulizer used for?
A nebulizer is a breathing machine used to treat asthma. The nebulizer converts a liquid medication, usually a bronchodilator like albuterol, into a mist that can be easily and painlessly inhaled.

Serious reactions to nebulizer treatment are also possible and should be immediately reported to the prescribing physician. These dangerous symptoms may include ...
How does a nebulizer help?
Nebulizer treatment relaxes the breathing muscles and permits air to flow more easily in and out of the lungs. It also helps to loosen mucous in the lungs. Both of these benefits of nebulizer treatment help to decrease and prevent wheezing, shortness of breath, coughing, and tightness in the chest.
Can a nebulizer be used for exercise?
Nebulizer treatment may also be used in susceptible individuals as a means of preventing breathing difficulties during exercise. Nebulizers, which are only dispensed by prescription, come in a variety of sizes. Some require electrical outlets or can be plugged into a car cigarette lighter.
What are the disadvantages of using nebulizers?
reported similar findings with respect to better control of symptoms, independence in executing most of the chores, better working than inhalers, increased self-confidence, and lesser probability of going to the hospital.[33] However, it also highlighted certain disadvantages such as dependency on the nebulizers, longer time taken for the treatment procedure, practical restrictions to carry the nebulizers around, and feelings of embarrassment. A few patients also reported problems with cleaning and disinfection of the nebulizer parts.
What is inhalation therapy?
Inhalation therapy is the cornerstone in the treatment of obstructive airway diseases , especially chronic obstructive pulmonary disease (COPD).[1] Interestingly, with increase in the burden of respiratory diseases, there has also been an increase in the number and types of available inhalation devices for treating these diseases in the past few years.[1] More importantly, what differs in each type of device is the technology used for aerosol generation and hence the technique that a patient needs to employ for optimal drug delivery. Data suggest that all devices are nearly similar in their efficacy when used appropriately.[1,2] However, many real-world studies have highlighted the crucial role of the patient's ability to use the device correctly in governing optimal drug delivery to the lungs and thereby disease control.[3,4,5,6,7]
How much does FEV1 decrease?
Normally, forced expiratory volume in 1 s (FEV1) decreases at the rate of 25–30 mL/year from the age of 35–40 years, and the decrease can be up to 60 mL/year after 70 years of age. [12] In COPD, the rate of decline in FEV1is accelerated and depends on the severity of the disease.[13] Such a decrease in lung function impacts the patient's ability to generate an adequate inspiratory capacity and use inhaler devices efficiently, especially DPIs.
Is nebulization a good treatment for COPD?
Inhalation therapy is the cornerstone of chronic obstructive pulmonary disease (COPD) management. However, for many COPD patients who are managed at home, nebulization therapy offers an effective alternative treatment and fulfills the gap of catering to the specific population of patients who are unable to use handheld inhaler devices appropriately. The present review highlights key aspects, namely selection of the right beneficiaries for home nebulization, available drugs in ne bulized formulations for the treatment of COPD, and the importance of care, cleaning, and maintenance, which are prerequisites for ensuring successful nebulization therapy.
Is nebulized medicine available in India?
Approved nebulized drugs available in India, which can be prescribed for maintenance nebulization in obstructive airway diseases (modified from Ghoshal et al., 2017[10])
Can a nebulizer be used for COPD?
The 2001 European Respiratory Society (ERS) guidelines by the ERS task force on the use of nebulizers recommend maintenance therapy with nebulizers for home use only after adequately ensuring failure to optimize treatment with handheld inhalers.[11] However, in certain groups of COPD patients, nebulizers can be particularly useful. A review by Dhand et al. describes various clinical scenarios where maintenance therapy with nebulization is the most appropriate choice of treatment for elderly patients with COPD[9] [Table 1].
What is a nebulizer?
A nebulizer is a device that turns liquid medicine into a mist. As you breathe, the mist of medicine moves into your lungs. The medicine may be an antibiotic or other medicine for your lungs. The nebulizer is usually connected to a machine that pushes air through the nebulizer. The air helps turn the medicine into a mist.
How to disinfect a nebulizer?
Disinfect every other day after treatment. Soak the nebulizer parts, except the mask, in 1 part diluted white vinegar and 3 parts hot water. Let them soak for 1 hour. Rinse the parts, shake off excess water, and let them air dry. You can also attach the nebulizer pieces to the machine.
How to mix nebulizer medicine?
Prepare the medicine. If your medicine is premixed, open it and place it in the nebulizer medicine container. If you have to mix medicines, place the correct amounts into the container using a dropper or syringe. Add saline if needed. You may need to add saline (saltwater) to your medicine container. Buy sterile normal saline at a pharmacy.
How to dry a nebulizer?
Wash the container and mouthpiece or mask with dish soap and hot water. Shake off the excess water and let the parts air dry. You can also attach the nebulizer pieces to the machine. Turn the machine on to dry the nebulizer quickly. Make sure all pieces are completely dry before storing them away.
How to prevent germs from getting into lungs?
Wash your hands with soap and water before preparing the nebulizer for use. This may prevent germs from getting into your lungs. .
What is breathing treatment?

Can you use saline solution in a nebulizer?
You may need to add saline (saltwater) to your medicine container. Buy sterile normal saline at a pharmacy. Do not use homemade saline solution in a nebulizer.
How long should a nebulization room be closed?
The room should be left vacant, with the door closed for 30 min after the patient has vacated the room post nebulization[37]
Why use a mesh nebulizer?
Unlike jet nebulizers, mesh nebulizers are preferred as nebulizing device because their medication reservoir is isolated from the breathing circuit that eliminates the nebulization of contaminated fluids.[7] Nebulizers may be required in critically ill COVID-19 patients receiving ventilatory support. In that case, it is important to keep the circuit intact to avoid the spread of the virus. Hence, delivering aerosolized medications via jet nebulizer or pressurized metered dose inhalers (pMDIs) will not be suitable due to the need for breakage of the circuits for placing the device on the ventilator circuit before aerosol therapy. A recently published guideline recommends using the mesh nebulizer in critically ill COVID-19 patients receiving ventilator support.[5] Mesh nebulizers can stay in line for up to 28 days, and the reservoir design permits adding medication without requiring the ventilator circuit to be broken for aerosol drug delivery. Furthermore, placing the mesh or jet nebulizer prior to the humidifier can improve the effectiveness of the treatment and also decrease retrograde contamination from the patient.[5] The time required for nebulization is equally important because the risk of viral transmission through aerosol is directly proportional to the nebulization. Therefore, mesh nebulizers are recommended in such cases as they have efficient drug delivery with the shortest nebulization time as compared to the commonly used jet nebulizers. With recent advances in technology, more innovative nebulizers, including breath-actuated and breath-enhanced nebulizers, decrease the amount of exhaled aerosol lost to the atmosphere while increasing the efficiency of drug delivery, thereby increasing the total inhaled drug mass. These will further minimize the risk of spreading the infection.[25]
What is fugitive emission?
Fugitive emission can be defined as aerosol that comes out from the aerosol device when the patient exhales. [5] . Studies have concluded that airborne transmission has been the main transmission route for the SARS-CoV-2 virus in the indoor cases.[11] .
What is medical aerosol?
Medical aerosols are aerosols that are not inhaled by the patient but spreads into the surrounding atmosphere. [5] Medical aerosols are produced by aerosol-generating medical procedures (AGMPs). Any procedure including nebulization, performed on a patient that can generate aerosols of various sizes, including droplet nuclei can be termed as AGMP.
What is a bioaerosol?
Bio-aerosols are generally defined as aerosols or particulate matter of animal, plant, or microbial, origin. Bio-aerosols can contain nonpathogenic or pathogenic dead or live viruses, bacteria, fungi, bacterial endotoxins, mycotoxins allergens, peptidoglycans, pollen, and plant fibers.[20] .
How far should a nebulizer be from the door?
Health-care workers should observe complete precautions, namely, facemask, eye protection, gloves, and gown. Maintain a safe distance (6 feet or greater), possibly outside the door, upon the setup of nebulizer. Limit the time the HCP is in the room without compromising patient care.
Is nebulization an AGP?
These AGPs potentially put HCPs and others at an increased risk for infection. As per the CDC recommendations, there is limited evidence that nebulization is an AGP.
