Hamilton公司推出无创呼吸机

现在出现了无创模式的呼吸机，采用压力支持通气，设计用来补偿峰值，从而将泄露相关的报警降至最低。

Hamilton公司推出了Rahphael重症监护呼吸机。通过面罩、口罩或者头盔方式提供无创呼吸模式，能够降低插管的需要，并能够早期拔掉插管。结果显示慢性阻塞性肺病的死亡率下降，慢性阻塞性肺病患者、急性肾功能衰竭患者的通气时间下降，呼吸机辅助肺炎的发病率下降。

一种软件升级增加了气管抵抗补偿功能，所有模式包括双向呼吸暂停储备，监测、控制、报警功能扩大，以及提供挪威语和韩国语的支持。软件还提供“最终配置”选择项，允许使用者在呼吸机切断电源之前，重新使设置生效。

Rhapael是一种紧凑型双相呼吸机，设计用于帮助儿童患者以及成年患者在各种模式和时相下更加自由的呼吸，覆盖了所有的临床需要：侵入性通气、自适应支持通气、以及无创通气。这种设备设计用于重症监护室、心脏手术恢复室、缓冲室、亚急性监护室以及长期监护中心。
 
 
Ventilators With Noninvasive Mode
 
Ventilators are now available with a noninvasive mode, which is an adaptation of pressure-support ventilation designed to compensate leaks and to minimize leak-related nuisance alarms.

Raphael intensive care ventilators are available from Hamilton Medical AG (Rhazuns, Switzerland). Noninvasive ventilation provided through a mask, mouthpiece, or helmet interface can decrease the need for intubation and promote early extubation. The results have shown reduced mortality in patients with chronic obstructive pulmonary disease (COPD), reduced ventilation time in COPD and acute renal failure (ARF) patients, and reduced complication rates of ventilator-assisted pneumonias.

A software upgrade adds tube resistance compensation, and all models now include bi-directional apnea backup, expanded monitoring, control, and alarm functions, as well as instructions in Norwegian and Korean languages. The software also provides a “last setup” option, enabling the user to resume ventilation at the settings in effect before the ventilator was last powered down.

The Rhapael is a compact biphasic ventilator designed to help pediatric and adult patients breathe more freely in all modes and phases, by covering the full range of clinical requirements: invasive ventilation, automated ventilation with adaptive support ventilation (ASV), and noninvasive ventilation. The unit is designed for use in the intensive care unit (ICU), cardiac surgery recovery, step-down units, subacute care units, and long-term care centers.
