Aerosol Therapy Correct Answer-refers to delivery of aerosol particles
to the respiratory tract.
1-humidification of dry inspired gases using bland aerosols
2-Improved mobilization and clearance of respiratory secretion,
including sputum induction, using bland aerosols of water and
hypertonic or hypotonic saline
3-delivery of aerosol drugs to respiratory tract Correct Answer-What are
the 3 main uses of aerosol therapy in respiratory care?
1-10µm Correct Answer-A major factor in lung penetration by aerosols
is particle size characterized by MMAD. The particle size of interest for
pulmonary application is in the ________________________ range.
5-10µm Correct Answer-Particle sizes ____________ tend to deposit
out in the upper airways and early airway generations.
10-15µm Correct Answer-There is 100% deposition in the nose and
mouth of particles larger than _________________.
2-5µm Correct Answer-_____________ have a greater probability of
reaching the lower respiratory tract from the trachea to the lung
periphery.
, aerosol Correct Answer-suspension of liquid or solid particles between
0.001 and 100 micrometers in diameter in a carrier gas.
stability Correct Answer-describing the tendency of aerosol particles to
remain in suspension
penetration Correct Answer-referring to depth within the lung reached
by particles
deposition Correct Answer-describing the process by which particles
deposit out of suspension to remain in the lung
10-15% Correct Answer-What percentage of a dose from an aerosol
device usually reaches the lower respiratory tract?
MDI Correct Answer-metered dose inhaler
SVN Correct Answer-small volume nebulizer
DPI Correct Answer-dry powder inhaler
MMD Correct Answer-mass median diameter: particle size above and
below which 50% of the mass of the particles are found
