|---|---|---|---|---|---|
| The larger the particle size, the larger the tendancy to_____? | RAIN OUT OF SUSPENSION
🗑
|
||||
| The greater the concentration of particles, greater the tendancy to what? | coalece into larger particles and RAIN OUT.
🗑

| WHAT DOES HIGH REALTIVE HUMIDITY DO TO AEROSOL? | GIVES A BETTER STABILITY OF AEROSOL PARTICULATES
🗑
|
||||
| Penetration? | depth within the resp. tract
🗑
|
||||
| deposition? | rain-out of aerosol particles
🗑
|
||||
| gravities effect on penetration and deposition? | decreases penetration and increases premature deposition(minimal effect on aerosol particulates)
🗑
|
||||
| Kinetic Energy is the same thing a ? | Temperature
🗑
|
||||
| What effect does inertial impaction have on aerosol therapy? | deposition of particles is increased at any pointe of directional change or increased airway resistance. Smaller airway diameter , greater the tendancy for deposition.
🗑
|
||||
| What is the most improtant variable that can be controlled while giving aerosol therapy? | Ventilatory pattern
🗑
|
||||
| Name 5 ideal ventilatory patterns? | 1. large slow inspired vital capacity over 3- 4 seconds 2. after 3-4 second breath holding for maximm deposition 3. Mask should be used with LG. vol. NEBS and USN's 4. Exhalation should be relaxed and normal 5. couging at the end of the treatment

| 3 clearance mechanism of Aerosols | 1. Mucociliary Escalator 2. Normal cough Mechanism 3. Phagocytosis by TypeIII alveolar cells
🗑
|
||||
| Bland aersol is given with which types of fluids? | 1. aerosolized sterile water 2. isotonic,hypertonic saline
🗑
|
||||
| Indications for aerosol therapy | 1.presence of upper airway edema, laryngotracheobronchitis, subglottic edema, postextubation edema, postoperative management of the upper airway, presence of a bypassed upper airway heated bland aerosol(hypertonic,hyotonic,mucomist)
