The patient is a 54-year-old man who presented with dizziness. Upon examination, he was found to have left beating nystagmus that changed to right beating nystagmus. While peripheral vestibular signs were initially observed, central vestibular signs emerged later. Based on the history and examination findings, the possibility of either peripheral vestibular neuritis or central stroke was considered. Three physical exam findings - direction-changing nystagmus, skew deviation, and head impulse test - can help distinguish between peripheral and central causes of acute vestibular syndrome with high sensitivity and specificity.

不定期開催のEMCNAカンファレンスです。EMCNAとは「Emergency Medicine Clinics of North America」の略で、救急外来や集中治療室、麻酔領域において遭遇する症候・疾患についての総説をまとめた、年4回発行の良著です。
初回のテーマは「Severe ARDSの初期治療（Emerg Med Clin N Am 34 (2016) 1–14 ）」救急外来および集中治療室でしばしば遭遇するARDS, その基本的対応を再確認しました。
1) The document describes lung ultrasound findings for various lung conditions. Lung ultrasound can detect pneumothorax by the absence of lung sliding and evaluate interstitial syndrome by the presence of multiple B-lines.
2) It then discusses a study comparing the diagnoses of 301 ICU patients to their lung ultrasound findings using a standardized protocol. Common lung ultrasound findings and their sensitivity and specificity for different lung diseases are presented.
3) In summary, the document outlines the use of lung ultrasound to evaluate lung abnormalities and validate it as a diagnostic tool by comparing its findings to patient diagnoses in the ICU. Lung ultrasound can rapidly detect conditions like pneumothorax and interstitial syndrome.

Este documento proporciona instrucciones para tomar y analizar muestras de sangre arterial para medir los gases sanguíneos, así como conceptos básicos sobre el balance ácido-base y la interpretación de resultados de gasometría. Incluye detalles sobre cómo evitar errores al tomar la muestra, almacenarla y procesarla, así como cómo calcular el anión gap, bicarbonato corregido y determinar si existe una compensación respiratoria adecuada ante un trastorno metabólico.
