This term describes the suspension of liquid or solid particles in a gas.
What is an aerosol?
The type of aerosol suspension that most nebulizers used in respiratory care produce
What is heterodisperse?
This type of atelectasis results from persistent breathing at small tidal volumes.
What is compression atelectasis?
Effective airway clearance depends on this anatomical function to move mucus.
What is the "mucociliary escalator"?
Name a hazard or complication of postural drainage.
Cardiac arrhythmias
Increased intracranial pressure
Acute hypotension
This device is used to generate therapeutic aerosols and includes atomizers, nebulizers, and soft mist inhalers
What is a nebulizer?
The retention of aerosol particles resulting from contact with the respiratory tract mucosa
What is deposition?
This technique is recommended for an alert, cooperative postoperative patient to prevent atelectasis.
What is incentive spirometry?
This technique uses body positioning to drain secretions.
What is "postural drainage"?
Name the only absolute contraindication to turning a patient.
When the patient has unstable spinal cord injuries
This measure identifies the typical settling behavior of aerosol particles.
What is Mean Mass Aerodynamic Diameter (MMAD)?
Aerosol particles in the 5- to 10-µm range deposit
What is the upper airways?
One absolute contraindication for intermittent positive-pressure breathing (IPPB)
What is tension pneumothorax?
Name the three conditions that are associated with chronic production of large volumes of sputum.
What is cystic fibrosis, chronic bronchitis, and bronchiectasis?
Name the primary hazard of aerosol drug therapy.
The most common mechanism for large particle deposition (>5 µm) in the respiratory tract.
What is inertial impaction?
Primary mechanism for deposition of small particles
What is Brownian diffusion?
The mechanism by which CPAP therapy treats atelectasis.
What is recruitment of collapsed alveoli?
This hazard of positive airway pressure therapies involves excessive air entering the stomach.
What is "gastric distention"?
Name the process to which aerosol suspension changes over time.
The term for mass of drug leaving the nebulizer as aerosol.
What is the emitted dose?
Category: Lung Expansion
This is the primary fate of inhaled aerosol particles that are between 1 and 0.5 µm.
What is most are cleared during exhalation?
This approach increases alveolar pressure to enhance lung expansion.
What is "positive end-expiratory pressure (PEEP)"?
Retention of secretions can lead to full or partial airway obstruction. Name the complications that results in mucus plugging.
What is hypoxemia, atelectasis, and shunting?
A patient complains of a "tingling" feeling in her lips during an incentive spirometry treatment. The RT should instruct the patient to:
What is take slower breaths or breaks between therapy.
