Active clinical trials for "Hyperventilation"

Home ventilation techniques consist mainly of two techniques, Continuous Positive Airway Pressure or CPAP and Non Invasive Ventilation or NIV. Whether for CPAP or NIV, pressures are delivered to the patient via an interface. The efficacy of CPAP and NIV is conditioned in part by the observance of the patients to the device. Because the comfort and degree of satisfaction of the patients to its interface is a key factor of the observance, side-effects and satisfaction of patients need to be continuously evaluated with available interfaces for CPAP and NIV treated patients. The purpose of the research is the evaluation of interface side-effects and the degree of satisfaction of home care patients treated for at least three months with CPAP or NIV.

This study will evaluate respiratory function in people with fibromyalgia and whether or not breathing patterns in this patient group can be explained by stress, emotional or biomechanical variables. In addition, examine the relationship between physical ability and lactate values.

This study evaluates the safety and efficacy of the voluntary ventilatory response as prophylaxis for acute mountain sickness, measured by the Lake Louise Self-Report Score, comparing to a group using acetazolamide.

The study aims to provide Turkish version of Nijmegen Questionnaire for the evaluation of respiratory dysfunction in asthmatic subjects. The incidence of hyperventilation syndrome in asthmatic patients can be determined with the results of the study.

Dyspnea is a major symptom in pulmonary arterial hypertension and people with the same haemodynamic have generally different degree of dyspnea in pulmonary arterial hypertension. The hyperventilation syndrome is a frequent cause of dyspnea in general population and in respiratory diseases like asthma but has never been studied in pulmonary hypertension. The goal of this study is to measure the prevalence of pulmonary hypertension in a population of patients with controlled pulmonary arterial hypertension (PAH).

Following an acute COVID-19 infection, many patients suffer from long lasting physical symptoms that may greatly impair quality of life. Persisting dyspnea and other functional respiratory complaints could evoke Hyperventilation Syndrome (HVS) as a putative contributor of the long-COVID presentation in COVID-19 survivors. We aimed to assess the possible relationship between a HVS and previous acute SARS-CoV-2 infection.

Hyperventilation syndrome induce dyspnea and altered quality of life. the aim of this study is to assess the impact of chest physiotherapy on hyperventilation syndrome' symptoms

The Hyperventilation Provocation Test (HPTest) associated with end-tidal CO2 pressure (PETCO2) measurement is a diagnostic tool for idiopathic hyperventilation syndrome (HVS). However, interpretation of HPTest remains unclear regarding the relevant PETCO2 values to consider and the occurrence of subjective symptoms. This case-control study aims to identify accurate HPTest measurements for the diagnosis of HVS, regardless of symptoms occurrence.

In order to evaluate current anesthetic practice in the care of preterm infants and neonates, the investigators will retrospectively review surgical procedures in infants who are less than 60 weeks post-conceptual age in which an arterial cannula was placed intraoperatively or in situ upon arrival in the operating room. They will evaluate the mode of ventilation (pressure or volume-controlled), tidal volume or peak inflating pressure, the level of PEEP, inspired oxygen concentration (FiO2), and respiratory rate used during the procedure to determine the average minute ventilation.

Hyperventilation syndrome is associated with impaired quality of life. The aim of the study is to assess the relationship between work productivity, including absenteeism and presenteeism, and the severity of hyperventilation syndrome
