Objective: To describe clinical usage of the Paratrend 7 continuous arterial blood gas monitor in children.
Design: Children older than 24 months of age who required significant ventilatory intervention were eligible for sensor placement.
Interventions: The sensor was placed via the arterial catheter to measure pH, PCO2, PO2, and temperature. The simultaneous arterial blood gas value was recorded along with the sensor reading.
Results: The sensor functioned for as long as seven days and provided the clinicians with data on the patient's respiratory status. The statistical validity of the device when compared to the arterial blood gas showed that the bias/precision for pH was 0.006/0.024, for PCO2 -0.78/4.68 mmHg, and for PO2 1.9%/17.1% (mmHg).
Conclusions: This report demonstrates actual clinical use of continuous blood gas monitoring in children. The information obtained is a major asset to the management of critically ill children in the intensive care unit.

Histopathology of the small airways: Similarities and differences between ageing and COPD.

Age-related lung function decline is associated with small airway closure and gas trapping. The mechanisms which cause these changes are not fully understood. It has been suggested that COPD is caused by accelerated ageing.

Unlabelled: It is known that in most cases of congenital central hypoventilation syndrome (CCHS), apnoeas and hypoventilation occur at birth. Nevertheless, a detailed description of initial symptoms, including pregnancy events and diagnostic tests performed, is warranted in infants with neonatal onset of CCHS, that is, in the first month of life. The European Central Hypoventilation Syndrome Consortium created an online patient registry from which 97 infants (44 females) with CCHS of neonatal onset and PHOX2B mutation from 10 countries were selected.

Background: Multi-compartment computer models of heterogeneity in alveolar ventilation-perfusion ratios (VA/Q scatter) across the lung explain the significant alveolar-arterial (A-a) partial pressure gradients and associated alveolar dead-space fractions (VDA/VA) seen in anesthetized patients for both carbon dioxide and for anesthetic gases of different blood solubilities. However, the accuracy of a simpler two-compartment model of VA/Q scatter to do this has not been tested or compared to calculations from the traditional Riley model with "ideal", unventilated (shunt) and unperfused (deadspace) compartments.
Methods: Measurements of gas partial pressures in inspired and expired gas and arterial and mixed venous blood from 29 patients undergoing inhalational general anesthesia for cardiac surgery was used to compare the accuracy of two simple models of VA/Q scatter and lung gas exchange in predicting measured alveolar and arterial partial pressure differences, and associated alveolar dead-space calculations for the modern anesthetic gases isoflurane, sevoflurane and desflurane.

Objectives: The aim of this study was to evaluate the factors associated with non-invasive mechanical ventilation (NIMV) failure in acute cardiogenic pulmonary edema (ACPE) diagnosed in the emergency department.
Methods: This study was prospectively conducted at the Ege University Faculty of Medicine ED between February 19, 2021 and December 01, 2021. Patients who received NIMV with ACPE were included.
Fast is fine, but accuracy is everything: making intraoperative transfusion decisions using point-of-care testing.

Accurate and timely diagnostic information is a vital adjunct to clinical assessment to inform therapeutic decision-making, including decisions to transfuse, or not transfuse, blood components. A prospective cohort study of diagnostic point-of-care (POC) haemoglobin measurements on arterial or central venous samples from adults undergoing major noncardiac surgery compared three widely used devices, HemoCue®, i-STAT™, and the Rad-67™ pulse CO-Oxymeter® finger sensor device, against standard laboratory haemoglobin measurements, but importantly not against a blood gas analyser. The study focused on haemoglobin results below 100 g L to establish the utility of these devices to guide red cell transfusion decisions.
