(PharmaNewsWire.Com, January 03, 2017 ) The term pneumatic is referred to as using air or similar gas and a nebulizer is defined as an instrument that converts liquid into fine spray or mist. Thus, Pneumatic Nebulizer involves pressurized gas supply that helps push medication toward the mouth. Compressed gas is delivered through jet (valve) that creates negative pressure on the medication tank. The solution (medicine) to be aerosolized is first introduced in the gas stream and then sheared into a liquid film. This liquid film is unstable which rapidly breaks the solution into droplets due to the surface tension created by the tank wall. A baffle is placed in the aerosol stream, which helps in the formation of small particles and recycling the large particles to medication tank.
Pneumatic nebulizers are the most common type of nebulizers used by patients. These are suitable for almost all kinds of medication. Moreover, these are easy to handle and less expensive compared to other nebulizers (ultrasonic, mesh). Thus, the factors mentioned above drive the growth of the global pneumatic nebulizers market. Pneumatic nebulizers are further segmented into vented pneumatic nebulizers and breath-actuated pneumatic nebulizers.
Vented pneumatic nebulizers use two similar one-way valves which prevent the loss of aerosol in the environment. At the time of inhalation, the respiratory valve opens and gas vents through the nebulizer. During exhalation, the gas passes through another tube present in the mouth of the patient. Usage of two similar one-way valves reduces the risk of contamination as the patient does not exhale into the reservoir. Vented nebulizers are designed to release higher quantity of aerosol during inhalation. These nebulizers are compatible with almost all kinds of compressors and reduce the formation of waste in the tube. In addition, less pressure is required for drug delivery, which makes it more suitable for all age groups. This above mentioned factor accentuates the global market demand of vented pneumatic nebulizer.
Breath-actuated pneumatic nebulizers increase the aerosol drug delivery by generating aerosol at the time of inhalation. These devices produce aerosol only when the patient inhales. Thus, the drug is continuously being aerosolized, loss of drug is less and delivery is more efficient. There are three types of mechanisms used in breath-actuated pneumatic nebulizer drug delivery: manual breath-actuated, mechanical breath-actuated and microprocessor breath-actuated. Manual breath-actuated mechanism involves the thumb control regulation of aerosol production during inhalation and exhalation. Mechanical breath-actuated mechanism uses a valve that controls aerosol production during inhalation. This mechanism eliminates the utilization of storage bag or tank. Microprocessor breath-actuated nebulizer uses a compressor actuated by an electronic circuit which controls aerosol production during inhalation.
Breath-actuated pneumatic nebulizers reduce drug wastage at the time of delivery and are more efficient compared to vented nebulizers. Thus, all the factors mentioned above collectively drive the demand for breath-actuated pneumatic nebulizers. However, technological complications, loss of medication in the spray chamber during delivery associated with pneumatic nebulizers would restrict the overall market growth during the study period.
North America and Europe dominates the global market of pneumatic nebulizers due to rising prevalence of various respiratory disorders (asthma, cystic fibrosis and chronic obstructive pulmonary disease) and increasing geriatric population. Furthermore, government initiatives drive the pneumatic nebulizers market in North America and Europe. Asia-Pacific is considered as an emerging market due to growing market penetration in this region. Asian market growth will be fuelled by the presence of untapped opportunities due to extensive increase in the healthcare infrastructure (healthcare cost, healthcare facility and healthcare budget). Rest of the world (RoW) holds fourth position in the global pneumatic nebulizers market due to poor economic and health condition in most of the African countries.
