Description of IPV
The IPV sends small, fast bursts of air that open the airways. These small bursts of air also loosen and free mucus from airway walls. A continuous mist helps make mucus less sticky. The high flow rate encourages deep breathing, which helps air to get around and behind trapped mucus.
Instructions to Perform IPV Treatment
There will be five cycles of treatment. Each cycle lasts for five minutes and has its own settings. The basic settings for all five cycles include:
- Drive pressure between 25 psig (minimum) to 30 psig (maximum)
- Total solution = 20mL of normal saline or hypertonic dose, followed by normal saline for the duration of treatment
- Frequency settings start at 300 Hz and will decrease by 50 Hz for each cycle. Use the black arrow on percussion knob to obtain correct frequency
||Position of Percussion Knob
||Turn black arrow completely counter clockwise
||Turn black arrow to the 9 o'clock position
||Turn black arrow to the 12 o'clock position
||Turn black arrow to the 3 o'clock position
||Turn black arrow completely clockwise
Make sure your child has a good seal with your mouthpiece or mask before your child begins the treatment.
- Turn system on and breathe normally through the mouth.
- The nebulizer will start the mini-bursts 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.
- If your child has a tracheostomy tube, verify that the cuff is deflated when administering IPV. Deflating the cuff will allow for the passing of a mucous plug and maintain a patent airway during the IPV treatment. A PEEP (positive end expiratory pressure) valve can be used on the exhalation side of the IPV circuit when a patient desaturates or requires a high level of PEEP.
- A safety check is performed prior to administration of the IPV to a tracheostomy tube. The safety check involves the following steps:
- Deflate the ETT tracheostomy tube cuff.
- Match the color codes lines coming from the IPV machine to the corresponding colors on the nebulizer cup.
- Turn the IPV machine on and ensure proper operation prior to placing the machine on the patient.
- Children whose doctor ordered cough assist treatments will use this in place of a Huff cough.
Cleaning the IPV
- After each use rinse with sterile water and air dry on clean paper towel.
- Wipe down the tubing and machine.
- Wash with soapy water and disinfect daily.
