Which component of an equine nebulizer system generates the airflow needed to create aerosol?
Compressor
Nebulizer cup
Tubing
Mask
The compressor provides the pressurized air or gas that passes through the nebulizer cup to generate aerosol droplets. The nebulizer cup, tubing, and mask are passive components that do not produce airflow.
Which piece of the nebulizer interfaces directly with the horse's airway?
Mask or mouthpiece
Compressor
Air inlet filter
Pressure regulator
The mask or mouthpiece is the patient interface that delivers aerosolized medication to the horse's airway. The other components are upstream and do not contact the respiratory tract directly.
What is the function of the nebulizer cup in an equine nebulizer system?
To hold and aerosolize the medication solution
To generate airflow
To filter exhaled air
To power the device
The nebulizer cup is designed to contain the liquid medication and convert it into aerosol droplets via the force of compressed air. Other components either supply air or manage flow but do not hold medication.
Before assembling a nebulizer system, what is the first step an operator should take?
Wash hands thoroughly
Plug in the compressor
Fill the nebulizer cup
Attach tubing to the mask
Hand hygiene is critical to prevent contamination of the system and medication. Assembly and setup follow only after proper handwashing to maintain sterility.
In what form must medication be prepared for effective nebulization in an equine system?
Aqueous solution
Tablet form
Capsule form
Cream or ointment
Nebulizers require liquid (aqueous) solutions to generate fine aerosol droplets. Solid or semi-solid preparations cannot be aerosolized effectively.
Which factor most influences the size of aerosol droplets produced by a nebulizer?
Airflow rate
Medication volume
Mask fit
Compressor noise level
Airflow rate through the nebulizer nozzle determines the shear forces that break up the liquid into droplets, directly controlling particle size. Other factors have less impact on droplet formation.
What is the ideal mass median aerodynamic diameter (MMAD) for aerosol particles to reach the lower respiratory tract in horses?
1 - 5 microns
5 - 10 microns
0.1 - 1 micron
10 - 20 microns
Particles in the 1 - 5 µm range are most likely to deposit in the lower airways, maximizing therapeutic effect. Larger particles tend to deposit in the upper airways and smaller ones may be exhaled.
What is a commonly recommended airflow rate for equine nebulization treatments?
8 L/min
1 L/min
20 L/min
0.5 L/min
An airflow rate around 8 L/min provides sufficient shear force for aerosol generation without causing excessive turbulence or discomfort. Much lower or higher rates are not optimal for equine systems.
How often should the nebulizer cup be disinfected to maintain hygiene?
After each treatment
Daily
Weekly
Monthly
Disinfecting the nebulizer cup after each use prevents microbial buildup and cross”contamination. Less frequent cleaning risks infection and device fouling.
When calculating the required dose of a nebulized drug, which variable is essential?
Drug concentration
Ambient temperature
Horse's color
Mask brand
Knowing the drug concentration (mg/mL) is vital to determine the total dose delivered from a given fill volume. Other factors do not directly influence dose calculation.
A persistent hissing sound during nebulization most likely indicates which problem?
An air leak in the system
Low medication concentration
Proper device function
Solution overfill
A hissing noise typically signals air escaping from an imperfect seal or connection. Proper function should be quieter, and medication levels do not produce hissing sounds.
Which change will increase the average size of aerosol droplets produced?
Decreasing the airflow rate
Increasing the airflow rate
Using distilled water instead of medication
Cleaning the nebulizer cup
Lower airflow reduces shear forces at the nozzle, resulting in larger droplets. The other actions do not significantly increase droplet size.
If no aerosol is visible during operation, what should you check first?
Power connection to the compressor
Viscosity of the solution
Mask fit on the horse's muzzle
Medication flavor
A lack of power to the compressor means no airflow and no aerosol generation. Other issues only affect aerosol quality or comfort, not generation itself.
What is the typical medication fill volume range for a single equine nebulizer treatment?
2 - 5 mL
0.5 - 1 mL
10 - 15 mL
20 - 25 mL
Filling the cup with 2 - 5 mL of solution allows efficient aerosolization without overloading the device. Larger volumes can extend treatment times and reduce aerosol concentration.
How often should the flexible tubing of an equine nebulizer be disassembled for deep cleaning?
Weekly
Daily
Monthly
Annually
Weekly deep cleaning prevents biofilm buildup inside tubing while balancing workload. Daily is excessive, and less frequent cleaning risks contamination.
A nebulizer holds 4 mL of a 5 mg/mL solution and has a delivery efficiency of 20%. What is the actual delivered dose?
4 mg
20 mg
16 mg
2 mg
The total loaded dose is 4 mL × 5 mg/mL = 20 mg. With 20% efficiency, 0.20 × 20 mg = 4 mg is delivered to the airway.
A highly viscous drug solution is producing low aerosol output. Which adjustment is most effective to restore performance?
Dilute the solution with sterile saline
Increase the mask size
Decrease treatment time
Lower the solution temperature
Dilution lowers viscosity, improving nebulizer aerosolization efficiency. Changing mask size or treatment duration does not address solution viscosity directly.
During troubleshooting, the nebulizer's diffuser plate is found clogged with residue. What is the best corrective action?
Soak the diffuser plate in the manufacturer's recommended cleaning solution
Increase airflow rate
Replace the tubing
Add more medication to the cup
Soaking in the recommended cleaning solution dissolves residue without damaging components. Increased airflow or adding medication will not clear a clogged diffuser.
For high-level disinfection of nebulizer components at least monthly, which method is most appropriate?
Immersion in 2% glutaraldehyde for the recommended dwell time
Rinsing with tap water
Wiping with a dry cloth
Brief spray of isopropyl alcohol
Immersion in 2% glutaraldehyde provides high-level disinfection, eliminating resistant organisms. Tap water rinsing or dry wiping is insufficient for sterilization.
After confirming power supply and no visible leaks, aerosol output remains below expected. What is the next logical step?
Inspect and clean the air inlet filter
Increase airflow above recommended settings
Add additional medication volume
Remove the patient interface
A clogged air inlet filter restricts flow to the compressor and reduces aerosol output. Adjusting airflow above specs or adding medication does not resolve inlet blockages.
