Arterial blood gas (ABG) analysis is important for acutely ill patients and should be performed by qualified laboratorians. The existing manual verifications are tedious, time-consuming, and prone to send wrong reports. Autoverification uses computer-based rules to verify clinical laboratory test results without manual review. To date, no data are available on the use of autoverification for ABG analysis. All autoverification rules were established according to AUTO10-A. Additionally, the rules were established using retrospective patient data, and then validated by actual clinical samples in a "live" environment before go-live...

Background: Patients admitted to the intensive care unit (ICU) with acute respiratory failure (ARF) due to COPD have high mortality and morbidity. Acidosis has several harmful effects on hemodynamics and metabolism, and the current knowledge regarding the relationship between respiratory acidosis severity on the short- and long-term survival of COPD patients is limited. We hypothesized that COPD patients with severe acidosis would have a poorer short- and long-term prognosis compared with COPD patients with mild-to-moderate acidosis...

INTRODUCTION/PURPOSE: Peripheral capillary oxygen saturation (SpO2) is used as surrogate for arterial blood oxygen saturation. We studied the degree of discrepancy between SpO2 and arterial oxygen (SaO2) and identified parameters that may explain this difference. METHODS: We included patients who underwent cardiopulmonary exercise testing (CPET) at Cleveland Clinic. Pulse oximeters with forehead probes measured SpO2 and arterial blood gas (ABG) samples provided the SaO2 both at rest and peak exercise...

There are no recommended guidelines for monitoring parameters during venoarterial extracorporeal membrane oxygenation (VA-ECMO). We evaluated whether regional cerebral oxygen saturation (rScO2) could be a monitoring parameter for mortality during VA-ECMO. We retrospectively searched our database for adult patients who underwent VA-ECMO between April 2015 and October 2016 and identified 21 patients with rScO2 data. Their baseline and clinical characteristics during the first 7 days (vital signs, arterial blood gas results, ECMO variables, rScO2, Swan-Ganz catheter parameters, transthoracic echocardiography parameters, and outcomes) were collected and evaluated for associations with 28 day mortality...

Purpose: Although the role of the angiotensin II type 2 (AT2) receptor in acute lung injury is not yet completely understood, a protective role of this receptor subtype has been suggested. We hypothesized that, in a rodent model of acute lung injury, stimulation of the AT2 receptor with the direct agonist Compound 21 (C21) might have a beneficial effect on pulmonary inflammation and might improve pulmonary gas exchange. Materials and methods: Male adult rats were divided into a treatment group that received pulmonary lavage followed by mechanical ventilation (LAV, n=9), a group receiving pulmonary lavage, mechanical ventilation, and direct stimulation of the AT2 receptor with C21 (LAV+C21, n=9), and a control group that received mechanical ventilation only (control, n=9)...

BACKGROUND: Transcutaneous monitors are utilized to monitor a patient's respiratory status. Some patients have similar values when comparing transcutaneous carbon dioxide ( P tcCO2 ) values with blood gas analysis, whereas others show extreme variability. A retrospective review of data was performed to determine how accurately P tcCO2 correlated with CO2 values obtained by arterial blood gas (ABG) or capillary blood gas. METHODS: To determine whether P tcCO2 values correlated with ABG or capillary blood gas values, subjects' records were retrospectively reviewed...

Platypnoea Orthodeoxia syndrome is defined by dyspnoea and hypoxaemia exacerbated by orthostatic positioning and alleviated in recumbency. This condition has been reported in association with pulmonary, hepatic and cardiac disease. We describe a case herein of a 79 year old female who developed severe hypoxaemia and dyspnoea post laparoscopic cholecystectomy. A difference in arterial blood gas oxygen tension was demonstrated in the supine and erect positions on arterial blood gas analysis. A Patent Foramen Ovale (PFO) with a right to left shunt was evident on echocardiogram employing colour doppler and agitated normal saline studies...

Purpose: There are no evidence-based guidelines for volume replacement during surgical procedures such as laparoscopic cholecystectomy. However, the administration of a restrictive volume of crystalloids could be more cost-effective and safe. This trial aimed to determine the effectiveness and safety of a restrictive regimen of crystalloids in patients during laparoscopic cholecystectomy by analyzing its cost-effectiveness and 1-year morbidity rate. Patients and methods: In this randomized, prospective study, patients were assigned to one of three groups based on the volume of fluid administered: the restrictive group received 1 mL/kg/hr, the low liberal group received 5 mL/kg/hr, and the high liberal group received 15 mL/kg/hr of Ringer's solution intraoperatively...

Thyrotropin releasing hormone (TRH) is a tripeptide hormone and a neurotransmitter widely-expressed in the CNS that regulates thyroid function and that maintains physiologic homeostasis. Following injection in rodents, TRH has multiple effects including increased blood pressure and breathing. We tested the hypothesis that TRH and its long-acting analog, taltirelin, will reverse morphine-induced respiratory depression in anesthetized rats following intravenous(IV) or intratracheal(IT) administration. TRH (1 mg/kg plus 5 mg/kg/hour IV) and talitrelin (1 mg/kg IV), when administered to rats pretreated with morphine (5 mg/kg IV), increased ventilation from 50±6 to 131±7% and 45±6 to 168±13% (percent baseline; n=4±SEM), primarily through increased breathing rates (from 76+/-9 to 260±14% and 66±8 to 318±37%)...
