Aim: This study aimed to examine the vitamin D levels in children who experience breath-holding spells (BHS) and compare these with those of a healthy control group. The goal was establish connection between BHS levels.
 Method: records 98 patients, presented Pediatric Neurology Cardiology polyclinics Adıyaman University Training Research Hospital December 2019 October 2022, were retrospec...

Repeated epochs of breath-holding were superimposed to the regular training cycling program of triathletes to reproduce the adaptative responses to hypoxia, already described in elite breath-hold divers [Respir. Physiol. Neurobiol. 133 (2002) 121]. Before and after a 3-month breath-hold training program, we tested the response to static apnea and to a 1-min dynamic forearm exercise executed dur...

Few tasks are simpler to perform than a breath hold; however, the neural basis underlying this voluntary inhibitory behaviour, which must suppress spontaneous respiratory motor output, is unknown. Here, using blood oxygen level-dependent functional magnetic resonance imaging (BOLD fMRI), we investigated the neural network responsible for volitional breath holding in 8 healthy humans. BOLD image...

Background: Breath-holding test has been tested in some clinical scenarios and has proved to be of clinical utility. Objectives: To determine the maximum voluntary breath-holding time in patients with obstructive ventilator defects and in normal subjects and to correlate the breath-holding times with pulmonary function tests. Methods: We conducted a case-control study including patients with ob...

Our aim was to compare the clinical features of panic disorder (PD) patients sensitive to hyperventilation or breath-holding methods of inducing panic attacks. Eighty-five PD patients were submitted to both a hyperventilation challenge test and a breath-holding test. They were asked to hyperventilate (30 breaths/min) for 4 min and a week later to hold their breath for as long as possible, four ...

Endothelial progenitor cell is known to be able to repair injured vessels. We assessed the hypothesis that endothelial progenitor cell also modulates cerebral endothelial function in healthy status. We used transcranial color-coded sonography to measure middle cerebral arterial vasoreactivity to CO2 (breath-holding index) in healthy subjects and observed its relationship with the number of circ...

Background: Breath-holding spells (BHS) is a sudden and reflexive phenomenon that is common in infancy and early childhood. Despite the harmless nature of BHS, being subjected to this phenomenon is very stressful for parents and sometimes requires treatment. In this study, we evaluated the efficacy of fluoxetine therapy (as an anxiolytic medication) on ​​pediatric BHS....

There is evidence that the practice of yoga improves physical and mental performance. The present investigation was undertaken to study the effect of yoga training on visual and auditory reaction times (RTs), maximum expiratory pressure (MEP), maximum inspiratory pressure (MIP), 40 mmHg test, breath holding time after expiration (BHTexp), breath holding time after inspiration (BHTinsp), and han...

PURPOSE This randomized, controlled, double-blind study was designed to determine the optimal dose of remifentanil for preventing complications associated with the removal of a laryngeal mask airway (LMA) without delaying emergence. MATERIALS AND METHODS This study randomly assigned 128 patients to remifentanil effect-site concentrations (Ce) of 0 ng/mL (group R0), 0.5 ng/mL (group R0.5), 1.0...

The aim of this study was to investigate the effects of different breathing patterns on the kinematics of front crawl. Eleven college swimmers (10 men and one woman) performed seven 25-m front crawl trials at maximum intensity, with 2-min intervals between trials. One trial was performed in the breath-holding condition and six trials were performed using variable breathing frequencies (every tw...
