Non-invasive ventilation (NIV), the provision of ventilatory assistance without an artificial airway, has emerged as an important ventilatory modality over the last 20 years. Delivery of pressured air at a certain level through a nasal or oro-nasal mask improves oxygenation and reduces ventilatory muscle fatigue. The equipment consists of a ventilator (typically a CPAP or BiPAP machine) with tubing, headgear, nasal or facial mask, filter and humidifier (Figure 1). In this article, we will discuss the medical literatures that support the use of NIV safely and effectively on the general medical floor to treat respiratory failure secondary to acute exacerbation of chronic obstructive pulmonary disease (COPD) and congestive heart failure (CHF).
无创通气（NIV）是指在不使用人工气道的情况下提供通气支持，在过去20年中已成为一种重要的通气方式。通过鼻罩或口鼻面罩以一定水平输送加压空气可改善氧合并减轻呼吸肌疲劳。该设备包括一台带有管道、头带、鼻罩或面罩、过滤器和加湿器的呼吸机（通常是持续气道正压通气或双水平气道正压通气机器）（图1）。在本文中，我们将讨论支持在普通内科病房安全有效地使用无创通气治疗慢性阻塞性肺疾病（COPD）急性加重和充血性心力衰竭（CHF）继发呼吸衰竭的医学文献。
