Abstract PaCO2 affects cerebral blood flow (CBF) and its regulatory mechanisms, but the interaction between neurovascular coupling (NVC), cerebral autoregulation (CA), and cerebrovascular reactivity to CO2 (CVR), in response to hypercapnia, is not known. Recordings of cerebral blood flow velocity (CBFv), blood pressure (BP), heart rate, and end-tidal CO2 (EtCO2) were performed in 18 subjects du...

BACKGROUND According to the guidelines for treatment of multiple trauma patients, immobilization of the neck and neck collar fixation are essential. However, following neck collar fixation patients usually experience dyspnea. Some studies have found that neck collar fixation can lead to decreased pulmonary volumes, yet there have been no studies on the effect of neck collar fixation on patient ...

This is a case series with chart review of 59 consecutive pediatric patients with a diagnosis of cervical esophageal coin who underwent anterior-commissure laryngoscope (ACLA) extraction during apnea. The purpose of this study was (1) to evaluate the efficacy and safety of coin extraction and (2) to analyze foreign body features and intraoperative physiological parameters (apnea time, O2 satura...

Purpose: This study aimed to analyse the effect of End-Tidal Carbon Dioxide (ETCO2) monitoring on patients who had been poisoned and presented in emergency department with decreased consciousness. Methods: The data over 18 years old presenting poisoning from 2016 2020 was collected department. We retrospectively analyzed their medical records, defined a Glasgow Coma Scale (GCS) score 9 or less ...

Endtidal carbon dioxide (ETCO2) is the measurement of CO2 in exhaled respiratory gases and serves as an estimate of arterial CO2. ETCO2 is measured by a capnograph in a mainstream or sidestream method. A no...

Results We registered data from 595 cardiac arrest patients; in 58.9 % (n=350) of these cases the pre-hospital critical care teams performed pre-hospital endotracheal intubation. An initial end-tidal CO2 measurement following prehospital endotracheal intubation were available in 270 cases. We identified 22 patients, who had an initial ETCO2 below 1.33 kPa. Four of these patients achieved return...

Previous studies have reported mixed results when correlating etCO2 and PaCO2 in mechanically ventilated patients with underlying respiratory disease. However, the utility and accuracy of capnography in nonintubated patients, without chronic pulmonary disease, has received little attention. We studied 25 nonintubated surgical patients to (1) examine the correlation between PaCO2 and etCO2 and (...

EDITOR: Ventilatory problems during surgery in the prone position may be a serious complication [1]. We report an incident where there was dissection of a reinforced endotracheal tube that led to its partial obstruction. This case shows an unexpected complication from reusing products intended for single use. A 62-yr-old female (weight 68 kg) who was scheduled for total laminectomy with posteri...

Introduction Out-of-hospital cardiac arrest (OHCA) generally has a poor prognosis. The development and use of a mechanical chest compression device has been suggested as a measure to achieve sufficient and continuous cardiopulmonary resuscitation (CPR). The mechanical chest compression device (Autopulse®) consists of a battery-driven board with a band attached that applies a 20% anteriorposteri...
