What is the main purpose of bland aerosol therapy?
To deliver aerosolized medication
To provide moisture and cooling to the airway
To deliver high concentrations of oxygen
To measure lung volumes
Bland aerosol therapy uses water or saline droplets to humidify and cool the respiratory tract without delivering any drugs. It helps maintain mucociliary function and soothes irritated airways. This therapy is not intended to deliver medication or alter oxygen concentration significantly. Wikipedia
Which device generates bland aerosol by using compressed gas forced through a small orifice?
Jet nebulizer
Ultrasonic nebulizer
Dry powder inhaler
Metered dose inhaler
A jet nebulizer creates bland aerosol by forcing compressed gas through a small nozzle, entraining liquid to form droplets. Ultrasonic nebulizers use high-frequency vibrations instead of gas flow. Dry powder inhalers and MDIs are used for medicated aerosols, not bland water droplets. Wikipedia
What particle size range is most effective for upper airway humidification rather than lower airway deposition?
Less than 1 µm
1 to 5 µm
Greater than 10 µm
3 to 7 µm
Larger particles, typically greater than 10 micrometers, tend to deposit in the upper airway and provide effective humidification there. Smaller particles can travel deeper into the lower respiratory tract. Bland aerosol therapy aimed at upper airway moisture uses particles that are too large for significant lower airway deposition. Wikipedia
Which of the following is a major hazard of bland aerosol therapy?
Bronchospasm in all patients
Significant fluid overload
Oxygen toxicity
Excessive sedation
Excessive bland aerosol therapy can lead to fluid overload, especially in patients with compromised cardiac or renal function. While bronchospasm can occur in sensitive individuals, fluid overload is more broadly recognized as a major hazard. Oxygen toxicity and sedation are not direct hazards of bland aerosol. Wikipedia
Which condition is an indication for bland aerosol therapy?
Croup-associated upper airway edema
Acute bacterial pneumonia
Active pulmonary tuberculosis
Intracranial hypertension
Bland aerosol therapy is indicated for croup or other causes of upper airway edema to deliver cool, humidified mist and reduce swelling. It is not used to treat infections directly or affect intracranial pressure. The therapeutic effect is primarily physical, providing moisture and cooling. Wikipedia
Bland aerosol therapy is generally contraindicated in patients with which condition?
Pulmonary edema
Chronic bronchitis
Asthma
Tracheostomy
In patients with pulmonary edema, additional fluid from bland aerosol therapy can worsen fluid overload. Chronic bronchitis, asthma, and tracheostomy patients may still benefit from humidification, albeit with caution in asthma due to bronchospasm risk. Careful assessment is needed in fluid-overloaded states. Wikipedia
What type of solution is most commonly used in bland aerosol therapy reservoirs?
0.9% sodium chloride solution
Hypertonic 3% saline solution
Sterile water with antibiotics
Distilled water with preservatives
A 0.9% (isotonic) sodium chloride solution is commonly used because it matches the body's osmolarity, reducing the risk of fluid shifts. Hypertonic solutions can draw fluid into the airway, and preservatives or antibiotics are not added to bland aerosol reservoirs. Using pure sterile water without additives is not ideal due to osmolar differences. Wikipedia
Which factor increases aerosol output from a jet nebulizer?
Increasing driving gas flow
Increasing reservoir volume
Decreasing driving gas flow
Using a smaller orifice
Increasing the driving gas flow in a jet nebulizer raises the velocity of gas through the orifice, producing more aerosol droplets and increasing output. Decreasing flow or changing reservoir volume has minimal direct effect. The orifice size is fixed in most devices. Wikipedia
Cool aerosol therapy primarily helps with:
Reducing airway inflammation and edema
Delivering aerosolized antibiotics
Increasing oxygen concentration
Measuring ventilation parameters
Cool aerosol therapy provides moisture and a mild cooling effect that can reduce airway inflammation and edema. It does not deliver medications, alter gas concentrations significantly, or measure ventilatory mechanics. The physical properties of the aerosol help soothe the mucosa. Wikipedia
How often should the water reservoir of a large-volume nebulizer be changed to minimize infection risk?
Every 1–2 hours
Twice a day
Daily
Only when empty
Changing the water reservoir daily or between patients is recommended to reduce bacterial contamination. Frequent changes help maintain aseptic technique. Water should never be changed only when empty as bacteria can proliferate in stagnant fluid. Wikipedia
Adding saline to the reservoir in bland aerosol therapy enhances:
Bronchoconstriction
Secretion clearance
Oxygen absorption
Sedation
Isotonic or slightly hypotonic saline can help mobilize secretions by loosening mucus in the airways. This enhances clearance without causing significant fluid shifts. It does not directly affect oxygen absorption or cause sedation. Wikipedia
What is the typical flow rate range for a cool large-volume jet nebulizer?
1–3 L/min
4–6 L/min
6–10 L/min
12–15 L/min
Large-volume jet nebulizers typically operate at flow rates between 6 and 10 liters per minute to generate adequate bland aerosol. Flow rates below this range yield less aerosol output, while much higher flows are uncommon in standard practice. Wikipedia
Which method best ensures delivery of warm bland aerosol?
Using an ultrasonic nebulizer at room temperature
Heating the reservoir to 37°C with a heating element
Adding ice packs around the reservoir
Using a dry powder inhaler
Heated large-volume nebulizers with temperature control set to body temperature (37°C) produce warm, humidified aerosol. Ultrasonic nebulizers at room temperature deliver cool aerosol, and ice packs produce cooler mist. Dry powder inhalers do not provide humidification. Wikipedia
What precaution helps prevent bacterial contamination of aerosol equipment?
Storing water overnight
Using tap water instead of sterile water
Changing water between patients
Adding antibiotics to the reservoir
Changing the reservoir water between patients or at least daily prevents bacterial growth and cross-contamination. Using sterile water is preferred over tap water, and adding antibiotics to reservoirs is not recommended due to resistance risk. Storing water overnight increases contamination risk. Wikipedia
What is the key difference between humidity and aerosol in respiratory therapy?
Humidity involves gaseous water vapor; aerosol involves liquid droplets
Humidity delivers drugs; aerosol does not
Aerosol is only hot; humidity is only cold
They are identical processes
Humidity refers to water in vapor form, which cannot be seen, whereas aerosol consists of visible liquid droplets suspended in gas. Both are used for airway humidification but differ in physical phase. Neither concept is limited to drug delivery or temperature alone. Wikipedia
To reduce particle impaction in the upper airway during bland aerosol therapy, one should:
Increase particle size
Decrease particle size
Increase flow rate
Use hypertonic solution
Smaller aerosol particles (<5 µm) are less likely to impact and deposit in the upper airway, allowing deeper penetration. Larger particles deposit earlier via inertial impaction. Flow rate and solution tonicity have different effects. Wikipedia
What does a high residual volume in a nebulizer indicate?
Efficient aerosol delivery
Excessive drug wastage
Improved humidity production
Lower bacterial contamination
A high residual volume means a significant amount of liquid remains unused in the nebulizer, leading to wasted drug or solution. Efficient delivery systems aim to minimize residual volume. It does not correlate with humidity production or contamination. Wikipedia
Which particle size is optimal for deposition in the lower respiratory tract?
Less than 1 µm
1 to 5 µm
6 to 10 µm
Greater than 10 µm
Particles in the 1 to 5 micrometer range are ideal for reaching the lower airways and alveolar regions because they avoid both inertial impaction and exhalation. Smaller particles may remain suspended, while larger ones deposit prematurely. Wikipedia
When using a cool aerosol tent for a child, which parameter must be closely monitored?
Inspiratory pressure
Ambient noise
Water temperature
Patient temperature
In a cool aerosol tent, enclosed space can alter temperature and humidity around the patient, so monitoring the child’s core temperature avoids hypothermia. Inspiratory pressures and noise are not primary concerns with passive tents. Wikipedia
What is a common complication of prolonged bland aerosol therapy?
Ventilator-associated pneumonia
Renal failure
Deep vein thrombosis
Coronary artery spasm
Stagnant water in nebulizers or circuits can harbor bacteria leading to ventilator-associated pneumonia in mechanically ventilated patients using bland aerosol therapy. Other listed conditions are unrelated to aerosol use. Wikipedia
Which type of water is recommended for filling a nebulizer reservoir?
Tap water
Sterile, distilled water
Chlorinated pool water
Dew collected outdoors
Sterile, distilled water is recommended to avoid introducing bacteria, minerals, or chemicals into the respiratory tract. Tap water and other unverified sources can contain contaminants and are not safe for nebulizer use. Wikipedia
What term describes condensation of aerosol within the ventilator tubing during heated humidification?
Rainout
Precipitation
Sublimation
Evaporation
Condensation of aerosol or water vapor inside ventilator circuits is commonly termed 'rainout.' This occurs when humidified gas cools below its dew point. It can lead to water accumulation and potential aspiration risk. Wikipedia
What is the maximum absolute humidity air can hold at 37°C?
22 mg/L
31 mg/L
44 mg/L
56 mg/L
At 37°C, the theoretical maximum absolute humidity of air is approximately 44 mg of water per liter, corresponding to 100% relative humidity at body temperature. This value is critical for clinical humidification targets. Other values correspond to different temperatures. Wikipedia
What is the approximate absolute humidity of air at 20°C and 100% relative humidity?
10.1 mg/L
17.3 mg/L
25.4 mg/L
43.8 mg/L
Air at 20°C and 100% relative humidity holds about 17.3 mg of water per liter. This parameter is often used to compare performance of humidification devices at room temperature. It helps in assessing moisture deficits. Wikipedia
