What is an Intrapulmonary Percussive Ventilator (IPV)?
The intrapulmonary percussive ventilator (IPV) provides high-frequency pulses to help move mucus and aid in lung recruitment. It is commonly used for patients with cystic fibrosis or patients on a mechanical ventilator.
Description of IPV
The IPV sends small, fast bursts of air that helps air get around and behind trapped mucus to open the airways and lungs. These small bursts of air also loosen and free mucus from airway walls. A continuous aerosol mist helps make mucus less sticky.
Instructions to Perform IPV Treatment
Prepare the machine for therapy.
- Set Operational Pressure between 30 to 35 psi.
- Add prescribed medications (ex. Hypertonic saline) or normal saline to phasitron nebulizer cup (max of 20mL). Add additional normal saline to cup as needed to maintain continuous aerosol mist for duration of treatment.
- Frequency settings and cycle time can vary by patient and condition. Below are two common treatment settings.
| CF Patient: 5 minutes per cycle, total treatment length is 25 minutes | ||
| Cycle | Target Frequency | Position of Percussion Knob |
| 1 | 300 cycles/min | Turn black arrow fully counterclockwise |
| 2 | 250 cycles/min | Turn black arrow to the 9 o'clock position |
| 3 | 200 cycles/min | Turn black arrow to the 12 o'clock position |
| 4 | 150 cycles/min | Turn black arrow to the 3 o'clock position |
| 5 | 100 cycles/min | Turn black arrow fully clockwise |
| Ventilator Patient: 10 minutes per cycle, total treatment length is 20 minutes | ||
| Cycle | Target Frequency | Position of Percussion Knob |
| 1 | 300 cycles/min | Turn black arrow fully counterclockwise |
| 2 | 200 cycles/min | Turn black arrow to the 12 o'clock position |
Instructions
- Perform a safety check prior to placing on patient. Turn machine on while occluding phasitron circuit and confirm proper operation and pressures.
- Make sure your child has a good seal with the mouthpiece or mask before beginning the treatment.
- Turn system on and breathe normally through the mouth. The nebulizer will start once the machine is turned on.
- Keep breathing normally, holding your cheeks tight, during the entire cycle.
- Turn machine off between cycles.
- Perform two to three sets of Huff coughing. Children whose doctor ordered cough assist treatments will use this in place of a Huff cough.
- Complete all cycles allowing time for Huff coughs or suctioning after each cycle and during cycles as needed.
Cleaning the IPV
- After each use, rinse the phasitron including nebulizer cup with sterile water and air dry on clean paper towel.
- Wipe down the tubing and machine.
- At end of day, wash with fragrance-free liquid soap, rinse with sterile water, and air dry on clean paper towel.
