Page 5: Welcome
Before operating these devices, please read the entire Clinical and Information Guides. VPAP ST-A indications for use The VPAP ST-A is indicated to provide noninvasive ventilation for patients weighing more than 13 kg or more than 30 kg in iVAPS mode with respiratory insufficiency or obstructive sleep apnoea (OSA). The VPAP ST-A is intended for home and hospital use. -

Page 8: Operating Information
Support EPAP Rise time Time Modes of operation The following table describes the operating modes available on the VPAP ST-A. Modes CPAP A fixed pressure is delivered. S (Spontaneous) You may set two treatment pressures-–one for inspiration (IPAP) and one for expiration (EPAP). The device senses when the patient is inhaling and exhaling and supplies the appropriate pressures accordingly. - Page 9 The following diagram illustrates these operating modes (excluding CPAP mode where a single level of continuous pressure is delivered). Long breath Very short breath (Leak or obstructive lungs) (Restrictive lungs) No breath effort Inspiration Patient Effort Expiration Leak flow IPAP EPAP IPAP EPAP...

Page 11: Target Alveolar Ventilation
Target alveolar ventilation iVAPS targets alveolar ventilation. Alveolar ventilation was chosen because it is at the level of the alveoli that gas exchange occurs. Total ventilation includes the ventilation devoted to the conducting airways, whereas alveolar ventilation best represents the useful portion of ventilation that reaches the alveoli. Alveolar ventilation cannot be measured directly, so iVAPS estimates it using a height approximated value of anatomical deadspace as shown in the graph below. -
Page 12: Target Patient Rate
Target Patient Rate iVAPS has a novel approach to providing a backup rate. Instead of mandating a fixed backup rate, iVAPS’ intelligent Backup Rate (iBR) will shift automatically between two limits, according to the context. The benefit of this approach is improved synchrony, while maximising iVAPS’ ability to maintain the target ventilation, at minimal pressure support. -
Page 13: Min/Max Ps
Min/Max PS The default settings for maximum and minimum pressure support are normally adequate, but you may wish to alter them in some patients. Min PS and Max PS define the range of pressure support adjustment available to the iVAPS algorithm as it regulates alveolar ventilation. -

Page 16: Climate Control
Climate Control The VPAP ST-A when used in conjunction with the H5i and ClimateLine or ClimateLine heated air tubing, offers a feature called Climate Control. Climate Control enables the automatic delivery of a constant value of absolute humidity to the patient’s upper airway while protecting against rainout and allowing patients to select the air temperature that offers the most comfort for them. -
