PURPOSE: An arterial blood gas analysis (ABG) yields important diagnostic information in the management of cardiac arrest. This study evaluated ABG samples obtained during out-of-hospital cardiopulmonary resuscitation (OHCPR) in the setting of a prospective multicenter trial. We aimed to clarify prospectively the ABG characteristics during OHCPR, potential prognostic parameters and the ABG dynamics after return of spontaneous circulation (ROSC). METHODS: ABG samples were collected and instantly processed either under ongoing OHCPR performed according to current advanced life support guidelines or immediately after ROSC and data ware entered into a case report form along with standard CPR parameters...

Record keeping for patients on non-invasive ventilation (NIV) at St. Georges Hospital is poor. The initial NIV prescription is often not recorded, and changes to the NIV prescription or the rationale for the changes (ABG results) are also poorly documented. This leads to confusion for nurses/doctors as to what the correct settings are, meaning patients could receive ineffective ventilation. The use of NIV is also poorly recorded by nursing staff meaning that doctors are unsure if the prescribed NIV is being achieved...

BACKGROUND: Spurious hypoxemia has been described in case reports during extreme hyperleukocytosis and has led to recommendations for immediate cooling and analysis of arterial blood gases (ABGs). We sought to determine, in samples processed as recommended, the magnitude of spurious hypoxemia in acute leukemia subjects with hyperleukocytosis. METHODS: A retrospective chart review was conducted of all subjects admitted between 2003 and July 2014 for acute leukemia, who presented with white blood cell (WBC) count > 50 × 10(9) cells/L and had ABGs performed...

INTRODUCTION: Acute chronic obstructive pulmonary disease (COPD) exacerbations can cause respiratory failure and may require non-invasive ventilation (NIV). There is a paucity of studies examining their NIV implementation within the emergency department (ED). AIM OF THE STUDY: The aims were (i) to establish whether NIV was beneficial for patients using arterial blood gas analysis (ABG), (ii) to observe whether current ED practice met the guidelines of obtaining ABG measurements within 15 minutes of arrival and commencement of NIV within 1 hour of clinical indication and (iii) to examine which healthcare professionals (HCPs) initiated NIV...

Middle ear ossicular reconstruction is a challenging task for any otologist. Over a period of time, surgeons have tried various types of materials as ossicular prosthesis with varying amount of success. In the last decade, numerous studies have been conducted that have proved that titanium prosthesis is biocompatible. We have conducted this study to investigate the efficiency of titanium middle ear prosthesis (Eon Meditech Pvt. Ltd.) in tympanoplasty. Nineteen patients who underwent tympanoplasty with titanium prosthesis placement from January to October 2010 were included in the study...

As defined by the American Association for Respiratory Care, respiratory care protocols are "guidelines, usually written in algorithmic form, for providing respiratory therapy services." The need for protocols has been framed by the frequent occurrence of misallocation of respiratory care, consisting both of over-ordering (ie, prescribing respiratory care that is unlikely to confer benefit) and under-ordering services (ie, failing to prescribe services that would be expected to offer benefit). In this context, the current paper reviews available studies regarding the effectiveness of respiratory care protocols...

INTRODUCTION: End tidal CO2 (ETCO2) has been established as a standard for confirmation of an airway, but its role is expanding. In certain settings ETCO2 closely approximates the partial pressure of arterial CO2 (PaCO2) and has been described as a tool to optimize a patient's ventilatory status. ETCO2 monitors are increasingly being used by EMS personnel to guide ventilation in the prehospital setting. Severely traumatized and burn patients represent a unique population to which this practice has not been validated...
