Jason An, Branko Braam
Rationale: We hope to increase awareness that hypokalemic paralysis may be the first presentation of Sjögren syndrome, for which potassium-sparing diuretics can be an effective adjunct to potassium replenishment. Presenting concerns: A 73-year-old female presented to a peripheral hospital with quadriparesis and a critically low serum potassium of 1.6 mmol/L with U waves on the electrocardiogram (ECG). The initial arterial blood gas showed a pH of 7.19, bicarbonate of 13 mEq/L, and a CO2 of 35 mm Hg...

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...

BACKGROUND: Interest in the anesthetic use of xenon, a noble gas, has waxed and waned for decades, and the clinical effects of xenon are still debated. We performed a meta-analysis to compare the clinical efficacy of xenon with that of propofol. METHODS: Electronic searches were performed through December 2017 using various databases, including PubMed, Embase, and the Cochrane Library. We identified thirteen trials that included a total of 817 patients. RESULTS: Patients treated with xenon had a lower bispectral index (BIS) (weighted mean difference (WMD): -6...

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...

Obesity leads to sleep disordered breathing (SDB), as manifested by recurrent upper airway obstructions during sleep termed obstructive sleep apnea and carbon dioxide retention due to obesity hypoventilation. The objective of this work was to characterize breathing during sleep in C57BL6/J mice with diet-induced obesity. Arterial blood gas was measured in nine obese and nine lean mice during wakefulness. Nine male mice with diet induced obesity and six lean male C57BL/6J mice were head mounted with EEG and EMG electrodes...

BACKGROUND: Until recently, it has been considered essential to maintain the use of a double-limb circuit in patients with amyotrophic lateral sclerosis (ALS) to avoid rebreathing expired air during invasive mechanical ventilation. Currently, life-sustaining home ventilators can work with a single, lighter circuit that is easier to manage. Our aim was to evaluate the effectiveness and safety of a single-limb circuit with intentional leaks (passive circuit) in comparison with a circuit with an expiratory valve (active circuit), in subjects with ALS who use invasive home ventilation...

Accurate, quantitative assessment of retinal blood oxygen saturation ( sO2 ) may provide a useful early indicator of pathophysiology in several ocular diseases. Here, with visible-light optical coherence tomography (OCT), we demonstrate an automated spectroscopic retinal oximetry algorithm to measure the sO2 within the retinal arteries (A- sO2 ) and veins (V- sO2 ) in rats by automatically detecting the vascular posterior boundary on cross-sectional structural OCT. The algorithm was validated in vitro with flow phantoms and in vivo in rats by comparing the sO2 results, respectively, to those obtained using a blood gas analyzer and pulse oximetry...

Background: Epicardial adipose tissue (EAT) releases both adiponectin and TNFα, and these two adipokines play important roles in heart diseases such as coronary arterial disease. The aim of the present study was to clarify whether fatty acid (FA) profiles in EAT are linked to the serum concentration of these adipokines. The relationships between serum adipokine levels and FA profiles in patients undergoing cardiovascular surgery were analyzed. Methods: Patients ( n  = 21) undergoing cardiovascular surgery (11 males, 70...

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)...

To study the effect of microgravity on peripheral oxygen saturation (SpO 2 ) in rats, tail-suspended rats were applied to simulate microgravity environment. SpO 2 and arterial oxygen saturation (SaO 2 ) were measured by pulse oximeter and arterial blood gas analyzer (ABGA) respectively on the 14th day, 21st day and 28th day in tail-suspended group and control group. Paired t -test shows that SpO 2 was significantly lower than SaO 2 in tail-suspended group on the 14th day ( P < 0.05), the 21st day ( P < 0...

BACKGROUND: Extracorporeal carbon-dioxide removal (ECCO2 R) might allow ultraprotective mechanical ventilation with lower tidal volume (VT) (< 6 ml/kg predicted body weight), plateau pressure (Pplat ) (< 30 cmH2 O), and driving pressure to limit ventilator-induced lung injury. This study was undertaken to assess the feasibility and safety of ECCO2 R managed with a renal replacement therapy (RRT) platform to enable very low tidal volume ventilation of patients with mild-to-moderate acute respiratory distress syndrome (ARDS)...

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...

BACKGROUND: In contrast to conventional mandatory ventilation, a new ventilation mode, expiratory ventilation assistance (EVA), linearises the expiratory tracheal pressure decline. OBJECTIVE: We hypothesised that due to a recruiting effect, linearised expiration oxygenates better than volume controlled ventilation (VCV). We compared the EVA with VCV mode with regard to gas exchange, ventilation volumes and pressures and lung aeration in a model of peri-operative mandatory ventilation in healthy pigs...
