Background: The prone position is commonly used in surgical procedures and is known to cause significant hemodynamic changes, particularly a reduction in cardiac output. This study aimed to explore the relationship between intra-abdominal pressure (IAP), airway pressure, and cardiac output during spine surgeries under general anesthesia.

Methods: Twenty-five patients undergoing elective spine surgery in the prone position were enrolled in this prospective observational study.

Severe bradycardia in patients with obstructive sleep apnoea and good early response to CPAP.

Sleep Breath

January 2025

Department of Cardiac and Vascular Diseases, Jagiellonian University Medical College, John Paul II Hospital, Prądnicka 80, Kraków, 31-202, Poland.

Background: Obstructive sleep apnoea (OSA) may lead to heart rhythm abnormalities including bradycardia. Our aim was to ascertain clinical and echocardiographic parameters in patients with OSA in whom severe bradycardia was detected in an outpatient setting, as well as to evaluate the efficacy of CPAP therapy on heart rate normalization at the early stages of treatment.

Methods: Fifteen patients mild, moderate or severe OSA and concomitant bradycardia were enrolled.

Non-invasive ventilation has been used as a pre-oxygenation strategy for rapid sequence intubation in the emergency department and the intensive care unit, yet, limited research has examined its use in the transport setting. These case reports discuss the use of non-invasive ventilation via a Hamilton T1 ventilator (Hamilton Medical) during transport by an air medical crew for pre-oxygenation before intubation in two cases. In both cases, a non-invasive, bilevel-positive airway pressure mode with a backup rate was used to achieve adequate airway pressures while allowing for a two-handed seal by one EMS clinician as the other prepared the equipment and medications.

: Obstructive Sleep Apnea (OSA) is a prevalent sleep disorder characterized by intermittent upper airway obstruction, leading to significant health consequences. Traditional diagnostic methods, such as polysomnography, are time-consuming and resource-intensive. : This study explores the potential of proton-transfer-reaction mass spectrometry (PTR-MS) in identifying volatile organic compound (VOC) biomarkers for the non-invasive detection of OSA.

Purpose: There is limited evidence to guide the treatment of enteral nutrition (EN) for children with bronchiolitis who receive biphasic positive airway pressure (BiPAP) support.

Methods: This quality improvement project included patients with bronchiolitis who were supported by BiPAP ventilation. An algorithm to increase EN treatment in those patients was created by stakeholders.
