OPERATING INSTRUCTIONS
Refer to physician’s prescrip(on or caregivers instruc(ons for appropriate seZngs for the Vibralung Acous(cal
Percussor. Regardless of which Y-‐adapter is used, opera(on of the Vibralung Acous(c Percussor is the same. The
pa(ent should hold the device in one or both hands while inser(ng the mouthpiece into the mouth and breathing
normally throughout the treatment.
1.
Power.
To power on the TCU, disconnect it from the charger, plug the HHT into it, and then press
the Power On/Off buYon.
• The LEDs embedded in the Power and Start/Pause buYons illuminate.
• The Low BaYery LED illuminates if the baYery is in need of recharging.
• The Unit is in Pause mode upon powering on.
2.
Mode Selec(on.
To select and acEvate a sepng,
• Press one of the 5 sepng buYons in the top row (L, M, H, R2 or R5).
-‐ The LED embedded in the selected sepng buYon illuminates.
• Press the Pause buYon to acEvate the device and emit sound at the selected sepng.
-‐ The LED embedded in the Pause buYon exEnguishes.
• Unless stopped or paused, the unit will operate at the selected sepng
for 10 minute and then terminate.
• Press the Pause buYon at any Eme while acEvated to pause the session.
-‐ The LED embedded in the Pause buYon illuminates.
• Press the Pause buYon while paused to resume the session.
-‐ The LED embedded in the Pause buYon exEnguishes.
• If a paused session is not resumed within 2 minutes by pressing the Pause buYon again,
the session automaEcally terminates.
Important: If a different treatment mode is desired before the currently selected mode has terminated, it is
necessary to power the TCU off, then power it on again and select the desired mode.
3. Resume, Terminate, Repeat.
To resume an automaEcally terminated session, or repeat a session with the same
sepngs, or start a different session with different sepngs, repeat steps 1 and 2 above and select the appropriate
sepngs.
4. Treatment.
To take the treatment, the paEent should place the mouthpiece in his or her mouth and seal their lips
around it just Eghtly enough to maintain a comfortable seal. The teeth may rest gently on the mouthpiece but the
paEent should be cauEoned to not bite down or chew on the son plasEc mouthpiece.
5. Pa(ent Posi(on.
Avoid recumbent paEent posiEoning while using the Vibralung AcousEcal Percussor. PaEent
should be sipng upright or at no more than a 30° recumbent angle to facilitate coughing and expectoraEon.
6. Breathing PaQern.
The paEent should breathe normally during the treatment. As with any breathing treatment,
hypervenElaEon or excessively deep or fast breathing may result in dizziness or light-‐headedness. The treatment
may be paused at any Eme and resumed if the paEent needs to rest.
7. Posi(ve Expiratory Pressure (PEP) Therapy.
Adjust the Variable Expiratory Resistor to apply PEP during resEng
breathing. Minimal PEP is applied when the orifice is wide open (60°) and maximal PEP when the orifice is at the
minimal posiEon (10°). An opEonal PEP manometer is available so that PEP levels can be monitored. Minimal PEP
levels will be observed during quiet Edal breathing due to relaEvely low respiratory flowrates. If desired, the
paEent may be instructed to perform an extended PEP maneuver by taking a deep breath and then exhaling slowly
while maintaining an expiratory flowrate sufficient to keep the PEP manometer in the 10 to 20 cmH2O pressure
range for 3 to 5 seconds. This maneuver can be repeated 10 to 20 Emes or as onen as desired for the paEent.
