Long-term effect of hyperoxemia during chronic obstructive pulmonary disease exacerbation managed by emergency medical service and emergency department: a prospective, exploratory study.

Objective: Long-term effects of hyperoxemia during acute exacerbation of chronic obstructive pulmonary disease (AECOPD) remained unknown. We aimed to explore these effects of hyperoxemia during AECOPD.

Methods: This was an exploratory follow-up study of a cohort with AECOPD managed by Emergency Medical Service and two emergency departments (EDs).

Most impactful predictors for hyperoxaemia in exacerbation of chronic obstructive pulmonary disease managed by Emergency Medical Services and Emergency Department.

Introduction: Hyperoxemia in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) leads to adverse outcomes. It remains prevalent in the pre-hospital Emergency Medical Services (EMS) and Emergency Department (ED).

Objective: To determine the key predictors for hyperoxemia in AECOPD in EMS and ED.

A common misunderstanding in lung ultrasound: the comet tail artefact.

The comet tail artefact is probably one of the most commonly and imprecisely used to describe vertical artefacts found in lung ultrasound. Two distinct artefacts are commonly observed: the lung comets and the B-lines. Both artefacts differ with regard to generation mechanism and clinical significance.

The Curtain Sign in Lung Ultrasound.

The curtain sign (CS) is a sonographic artifact found in lung ultrasound studies. It is generally used to describe the appearance of an expanded and aerated lung, often in the context of pleural effusion diagnosis. In emergency and critical care ultrasound use, the recognition of changes to the CS is very useful in the detection of early pulmonary pathological processes occurring at the lateral lung bases and costophrenic recesses.

Lung ultrasound-a primary survey of the acutely dyspneic patient.

There has been an explosion of knowledge and application of clinical lung ultrasound (LUS) in the last decade. LUS has important applications in the ambulatory, emergency, and critical care settings and its deployability for immediate bedside assessment allows many acute lung conditions to be diagnosed and early interventional decisions made in a matter of minutes. This review detailed the scientific basis of LUS, the examination techniques, and summarises the current applications in several acute lung conditions.

Nationwide improvement of door-to-balloon times in patients with acute ST-segment elevation myocardial infarction requiring primary percutaneous coronary intervention with out-of-hospital 12-lead ECG recording and transmission.

Study Objective: Reducing door-to-balloon times for acute ST-segment elevation myocardial infarction (STEMI) patients has been shown to improve long-term survival. We aim to reduce door-to-balloon time for STEMI patients requiring primary percutaneous coronary intervention by adoption of out-of-hospital 12-lead ECG transmission by Singapore's national ambulance service.

Methods: This was a nationwide, before-after study of STEMI patients who presented to the emergency departments (ED) and required percutaneous coronary intervention.

Public hospital preparations for SARS outbreak: experience of Alexandra Hospital.

Alexandra Hospital (AH) was one of the public hospitals in Singapore that responded to the severe acute respiratory syndrome (SARS) crisis. Being the only public hospital that remained "SARS-free", i.e.
