通气和无创模式（新生儿nCPAP）。
•有创通气模式提供一系列患者支持，
从完全控制的机械呼吸到压力支持
为自发呼吸的患者进行呼吸。
•非侵入模式旨在用于自发
仅限呼吸患者。
有关设置和的详细信息，请参见通风模式说明
每种模式提供的功能。
将患者设置为侵袭性和
使用的附件为无创通气。
•通过人工气道（例如。，
气管内管），其插入患者的气管中。
•使用正压进行无创通气
通过附件（如鼻面罩）进行通风，或
话筒。这些附件通常连接到
患者头部，以提高气道密封的质量
尽量减少气道泄漏。

ventilation and non-invasive modes (nCPAP for neonates). • Invasive ventilation modes provide a range of patient support, from fully controlled mechanical breaths to pressure supported breaths for spontaneously breathing patients. • Non-invasive modes are intended to be used for spontaneously breathing patients only. See ventilation mode descriptions for details about the settings and features each mode provides. The primary difference between setting up a patient for invasive and non-invasive ventilation is the accessories used. • Invasive ventilation is delivered through an artificial airway (e.g., endotracheal tube), which is inserted into the patient's trachea. • Non-invasive ventilation is delivered using positive-pressure ventilation through an accessory such as a nasal mask or mouthpiece. These accessories are often attached to the patient’s head to increase the quality of the airway seal to minimize airway leaks. Non-invasive ventilation masks should be non-vented and must not include an entrainment (inspiratory) valve. Patient circuits for use with non-invasive ventilation must be dual-limb with connections for both the inspiratory and expiratory ports of the ventilator. Mechanical and spontaneous breaths The ventilator offers multiple ventilation modes, which support mechanical and spontaneous breaths. Mechanical breaths are controlled by the ventilator. The ventilator uses the selected mode settings to determine the characteristics of the breath such as timing, volume, and pressure. Depending on which mode is set, mechanical breaths are initiated by the ventilator or the patient. • Ventilator-initiated: the ventilator uses the set respiratory rate to initiate a breath. • Patient-initiated: the patient activates the set inspiratory trigger (flow or pressure) to initiate a breath. Spontaneous breaths are initiated and controlled by the patient. Note CARESCAPE™ R860 5-2 2065490-001 In ventilation modes with a PS setting, spontaneous breaths are pressure-supported at the PS level. AB.100.034 1 2 3 Figure 5-1 • Breath Types 1.

Ventilation mode settings Ventilation mode settings are separated into four categories: • Main Parameters • Breath Timing • Patient Synchrony • Safety Each ventilation mode has a unique set of settings. See each ventilation mode description for a list of applicable settings. Quick Keys on the lower portion of the display provide access to ventilation mode settings that are likely to be adjusted frequently. The remaining settings can be adjusted in the Current Mode > Mode Settings menu. When changing ventilation modes, some settings may change if the two modes do not share the same limits or increments. • When the setting is greater than the maximum value allowed in the new mode, the maximum value is set.
