Humidity And Aerosol Therapy Flashcards
Water vapor
Condensation/ actual or absolute humidity
Anhydrous
Containing no water
Dew point
Temperature at which water vapor begins to condense into liquid water
Humidifier
A device to deliver humidity into a room or system
Aerosol
Suspension of liquid or solid particals
Gaseous medium
Inertial impact
Partial continues on a straight course depositing larger particles on sidewalls, smaller particles continue around the corner
Sideways slip
Primary humidity deficit
Saturation PH @ ambient temp - actual humidity @ ambient temp
Secondary humidity deficit
Posterior 2/3rds of nose
Saturation Ph @ body temp - saturation PH @ ambient temp
Body humidity
Relative humidity at body temperature
Piezoelectric transducer
Transducer vibrates at frequencies of ultrasonic waves applied
Relative humidity
Ratio of content (actual or absolute) to capacity
%
Measured using hygrometer
Reasons for aerosol use
Humidification of respiratory tract
Mobilize secretions
Sputum induction
Deliver medications
Clearance mechanisms
Describe
Exhalation
Mucocilliary clearance
Encapsulation
Phagocytosis
Hazards of ultrasonic nebulizer
Drug inactivation
Tendency to malfunction
El
Consequence of prolonged inspiration w improper conditioned gas
Impaired ciliary activity Impaired mucous movement Inflammation, necrosis of epithelium Retention of thick secretions Bacterial inflammation Atelectasis Pneumonia Illness, increased vent, decreased water intake, increased temp
