The coronavirus disease 2019 pandemic has raised fear throughout the nation. Current news and social media predictions of ventilator, medication, and personnel shortages are rampant.
Patients with coronavirus disease 2019 are presenting with early respiratory distress and hypoxemia, but not hypercapnia.
Patients who maintain adequate alveolar ventilation, normocapnia, and adequate oxygenation may avoid the need for tracheal intubation. Facemask continuous positive airway pressure has been used to treat patients with respiratory distress for decades, including those with severe acute respiratory syndrome. Of importance, protocols were successful in protecting caregivers from contracting the virus, obviating the need for tracheal intubation just to limit the spread of potentially infectious particles.
During a pandemic, with limited resources, we should provide the safest and most effective care, while protecting caregivers. Continuous positive airway pressure titrated to an effective level and applied early with a facemask may spare ventilator usage. Allowing spontaneous ventilation will decrease the need for sedative and paralytic drugs and may decrease the need for highly skilled nurses and respiratory therapists. These goals can be accomplished with devices that are readily available and easier to obtain than mechanical ventilators, which then can be reserved for the sickest patients.
2019年冠状病毒病大流行在全国引发了恐慌。当前新闻和社交媒体上关于呼吸机、药物和人员短缺的预测随处可见。
2019年冠状病毒病患者表现为早期呼吸窘迫和低氧血症,但无高碳酸血症。
维持足够肺泡通气、正常碳酸血症和足够氧合的患者可能无需气管插管。面罩持续气道正压通气已用于治疗呼吸窘迫患者数十年,包括严重急性呼吸综合征患者。重要的是,这些方案成功地保护了医护人员免受病毒感染,避免了仅为限制潜在感染性颗粒传播而进行气管插管的必要性。
在大流行期间,资源有限,我们应在保护医护人员的同时,提供最安全、最有效的护理。将持续气道正压通气滴定至有效水平并早期使用面罩可节省呼吸机的使用。允许自主通气将减少对镇静和麻痹药物的需求,并可能减少对高技能护士和呼吸治疗师的需求。这些目标可以通过比机械呼吸机更容易获得且随时可用的设备来实现,机械呼吸机则可留给病情最严重的患者。
