ResMed's COPD solutions
Improved gas exchange
ResMed’s Intelligent Volume Assured Pressure Support (iVAPS) therapy targets alveolar ventilation, improving gas exchange and reducing CO₂ levels in hypercapnic patients. Using advanced technology iVAPS combines the advantages of pressure support ventilation with the assurance of a target volume, maintaining alveolar ventilation even as a patient’s respiratory rate changes.
Studies have shown that iVAPS is as effective as high pressure NIV in increasing minute ventilation (MV) in obese patients with COPD.1
In another study iVAPS was more effective at reducing nocturnal hypercapnia in COPD patients compared to high pressure NIV (p=0.003). There was also a trend towards more restful sleep at home for patients randomized to iVAPS compared to patients on high pressure NIV.2
Making expert titration easy
According to experts iVAPS might help to simplify the establishment of effective long‐term NIV in stable hypercapnic COPD patients because it uses a pre‐defined inspiratory pressure range that, unlike high pressure NIV, does not require titration of IPAP over several days.2
Another study also found that iVAPS can alleviate some of the complex time‐consuming elements that are required for effective setup of NIV therapy.3 The researchers concluded that “iVAPS is as effective as pressure support initiated by a skilled healthcare professional in controlling nocturnal hypoventilation.” It may facilitate NIV use without extensive prior team experience, they said in their study published in the European Respiratory Journal.
60 minutes more3
Another benefit of iVAPS is that it can help overcome the challenges involved in getting patients to stay on NIV therapy long‐term.
Evidence from a study demonstrated that patients treated with iVAPS for the first time adhered to therapy for 60 minutes longer (per session) compared to treatment using standard pressure support modes.3
The study concluded that iVAPS “may encourage adherence to therapy for patients newly adjusting to NIV”.3
Intelligent, automatic and personalized, this advanced technology with an intelligent back‐up rate (iBR) offers a smart choice for managing patients with chronic stable COPD.
Through our range of homecare ventilators ResMed is committed to improving quality of life for COPD patients. Several NIV systems are available for use by COPD patients in the home:
For patients who need a quiet, easy‐to‐use, advanced bilevel solution ResMed offers the Stellar™ 150 ventilator (with iVAPS).
Light, small and quiet, Stellar 150 is optimal for patients at home, particularly those with mobility needs.
