Administering aerosol medication during high-flow therapy can be achieved in several ways,1 but there are challenges

Remove high-flow to administer aerosol medication1,2
Remove high-flow to administer aerosol medication1,2
- Temporary removal of high-flow oxygen therapy is considered by some as a risk factor that might contribute to the worsening of a patient’s respiratory failure1
- Patients, especially young children, may not tolerate a facemask or mouthpiece for long periods3
- Aerosol delivery via mouthpiece is not a viable option for infants and small children3,4
- When used, mask or mouthpiece interfaces may cause distress in children3,5

Use nebuliser with facemask placed over the nasal cannula1
Use nebuliser with facemask placed over the nasal cannula1
- Administering aerosol medication via facemask or mouthpiece and nebuliser with concurrent high-flow is associated with low drug delivery in vitro models6,7
- Recommendations state that placing a nebuliser with a mask or mouthpiece while the patient is concurrently receiving high-flow oxygen therapy significantly reduces the inhaled dose of the aerosolised drug to a negligible level, and this practice is not recommended8

In-line nebulisation during high-flow1
- Administering
aerosol via jet nebuliser placed in-line in a high-flow circuit is associated with low drug
delivery (1.0% of nominal dose; study performed in healthy subjects)9
- The
gas driving jet nebulisers can
interfere with high-flow oxygen content, humidity and temperature10
- Jet nebulisers generate noise,11 which
may make it difficult to maintain a calm environment for patients and staff
- It is
necessary to open the high-flow circuit to refill the medication cup of a jet nebuliser12
Aerogen provides effective medication delivery during high-flow therapy9,13–17†
Effectiveness
In studies, in-line aerosol drug delivery with Aerogen during high-flow was associated with:
~4x more medication delivered to the lungs (3.6%) with Aerogen during high-flow versus a jet nebuliser in healthy subjects (1.0%); P<0.05.†9
3.5–17% medication delivery to the lungs, depending on flow rates†13
In-line Aerogen supports bronchodilator response during high-flow therapy: significant improvement in lung function (FEV1, FVC and PEF) following salbutamol nebulisation via high-flow versus high-flow alone in patients with severe exacerbation of COPD16

Patient comfort
Use of the in-line Aerogen Solo to deliver nebulised therapy resulted in greater comfort and satisfaction versus use of a jet nebuliser plus facemask in critically ill infants receiving high-flow respiratory support.18
Patients with discomfort suggestive of pain and requiring intervention (COMFORT–behaviour scale score ≥17‡ AND comfort numerical rating score ≤6)18

Ease of use
Aerogen simplifies the workflow

Higher lung deposition with an in-line Aerogen vs jet nebuliser in healthy subjects9
Aerogen Solo can support aerosol drug delivery at every stage of a patient's respiratory journey: during invasive mechanical ventilation (IMV) and non-invasive supports such as non-invasive ventilation (NIV), HF and when self-ventilating (SV).17

- Virtually silent17,18
- 28 days intermittent or 7 days continuous use17
- No added flow required17
- Refill medication cup without opening the circuit17
- 6 mL cup17
