ResMed’s NIV technologies

COPD patients have unique ventilation needs. As airflow obstruction worsens and the time required for exhalation increases, patients can experience air trapping – causing significant load on the respiratory system. Successful ventilation relies on improving gas exchange and reducing the work of breathing, while also keeping the patient comfortable. Because of the different lung mechanics for COPD patients, maintaining patient-device synchrony is critical to successful home non-invasive ventilation. Asynchrony can cause significant discomfort, leading to poor compliance and clinical outcomes. Research indicates that 40% of non-invasive ventilation patients experience asynchrony in 10% or more of their breaths.1

ResMed’s range of NIV devices feature the following technologies to help address patient-device synchrony:

TiControl helps patients exhale. TiControl allows clinicians to limit the minimum and maximum amount of inspiratory time according to the patient’s disease state. For COPD patients whose respiratory flow is restricted and who experience challenges in exhaling, setting a shortened Ti Max (maximum time the patient can spend in inspiration) will prevent late cycling to expiratory pressure and can provide a better match to the patient’s ideal inspiratory time.

Adjustable trigger and cycle sensitivities. Adjustable trigger and cycle sensitivities allow further customization at the beginning and end of each inspiration, which further improves patient-device synchronization. Clinicians may want to consider setting the cycle sensitivity to high to provide an earlier cycle to exhalation.

Adjustable rise time. Rise time is the time it takes for the ventilator to reach the set inspiratory pressure after triggering. The greater the rise time value, the longer it takes for pressure to increase. A controllable rise time allows you to optimize the patient’s work of breathing, comfort and synchrony. For a COPD patient, a faster rise time setting ensures that the lungs fill quickly.

Ventilation with integrated oxygen

Several studies show that using oxygen at home for more than 15 hours a day increases quality of life when they have severe COPD and low blood levels of oxygen.2,3 For this reason, ResMed offers a variety of home therapy devices that allow you to easily integrate oxygen into the patient’s ventilation therapy.

Improved oxygen delivery and ventilation monitoring

Many of our solutions improve oxygen delivery with integrated FiO2 monitoring so that physicians can prescribe concentrations of oxygen which are more precise than liter flows (e.g. LPM). Our ventilators also allow you to take FiO2 monitoring one step further, with the option of integrated oximetry for objective patient monitoring.

ClimateLineMAX Oxy offers easy oxygen integration

Ideal for patients using a ResMed CPAP or bilevel device that requires supplemental oxygen, the ClimateLineMax™Oxy connects neatly to the back of the device, removing the inconvenience of a separate tube connection to the mask, and allowing the oxygen to completely mix with warmed, humidified air.
