Risk Stratification of COVID-19 Patients Using Ambulatory Oxygen Saturation in the Emergency Department.

Introduction: It is difficult to determine illness severity for coronavirus disease 2019 (COVID-19) patients, especially among stable-appearing emergency department (ED) patients. We evaluated patient outcomes among ED patients with a documented ambulatory oxygen saturation measurement.

Methods: This was a retrospective chart review of ED patients seen at New York University Langone Health during the peak of the COVID-19 pandemic in New York City.

Pre-hospital advanced airway management in children: a challenge that training can handle.

We respond to the Tarpgaard et al. article reporting on pre-hospital endotracheal intubation (PHETI) success and complications by Danish critical care teams including critical care anaesthetists. We compare the authors' results with previously published results from our service's experience with PHETI in a similar patient population, also with physician and paramedic medical teams.

Analysis of Out-of-Hospital Pediatric Intubation by an Australian Helicopter Emergency Medical Service.

Study Objective: We examine first-look success in emergency pediatric intubation by a physician-staffed helicopter emergency medical service (EMS).

Methods: A database analysis of all pediatric (<16 years) intubations during a 64-month period was undertaken, using data from a prospectively enrolled electronic airway registry form. Recorded findings included patient demographics, operator background, airway intervention including intubation attempts, complications, and critical timings.

Lung ultrasound: a useful tool in the assessment of the dyspnoeic patient in the emergency department. Fact or fiction?

Patients with respiratory distress present a frequent and challenging dilemma for emergency physicians (EPs). The accurate diagnosis and treatment of the underlying pathology is vitally important in these sick patients to ensure the best outcome and minimise harm from unnecessary treatments. Within the last decade, studies have shown lung ultrasonography (LU) to be valuable in the accurate diagnosis of a variety of lung pathologies, including cardiogenic pulmonary oedema, pleural effusion, pneumothorax, haemothorax and pneumonia.
