Pulmonary hypertension (PH) has three main types, pre-capillary PH, post-capillary PH, and combined pre-capillary and post-capillary PH, and it is based on mean pulmonary arterial pressure (PAP) > 20 mmHg measured with a right heart catheterization (RHC). Chronic thromboembolic pulmonary hypertension (CTEPH) is mainly defined as a pre-capillary PH and classed as a Group IV PH. It was reported that 0.1-9.1% of individuals with pulmonary embolism develop CTEPH within two years after the initial diagnosis, and CTEPH is the only PH category that has a chance of being cured, mainly by pulmonary endarterectomy. Sleep-related breathing disorders (SRBD) are defined as obstructive sleep apnea (OSA) disorders, central sleep apnea (CSA) syndromes, sleep-related hypoventilation disorders, and sleep-related hypoxemia. An SRBD may also lead to an increase in PAP primarily during sleep and cause nocturnal hypoxemia. Although SRBDs were reported in patients with pre-capillary PH, most of the studies included patients with idiopathic PAH. Although the cause-and-effect relationship between pre-capillary PH and SRBDs is uncertain, it is known that mPAP may increase during sleep in patients with OSA . Less is known regarding the occurrence of SRBDs in CTEPH. Previously a few study showed relationship between SRBDs an CTEPH as the main type was OSA. Most of the studies evaluated preoperative occurance and incidance of SRBDs in CTEPH. Only one study performed post operative SRBD on a cardiorespiratory device was conducted the night before and one month after elective pulmonary endarterectomy. In our previous study we showed that severe nocturnal hypoxemia (NH) is highly prevelant in preoperative CTEPH patients and the most common two types of SRBD are OSA and isolated sleep related hypoxemia (ISRH) and age, mPAP and AHI are independent determinants of severe NH. (J. Clin. Med. 2023, 12, 4639 https://doi.org/10.3390/jcm12144639) In this present study we aimed to investigate occurrence of SRBDs and mortality 5 years after pulmonary endarterectomy operation.
This study is a randomized controlled trial to evaluate whether EEG-guided calibration of inhalation agents can reduce occurrence of EEG discontinuity in infants during general anesthesia.
(1) Maximum respiratory pressure (MRP)1) Maximum inspiratory pressure (maximum intake pressure) and maximum expiratory pressure (MEP) Digital spirometer (Pony FX, COSMED Inc., Italy) are used to measure the micro-paste in a seated position. MIP is based on the pressure maintained for at least 1 second, inhaling or exhaling with maximum effort in the maximum exhalation state (=residual volume) and the maximum exhalation state (=total lung capacity). The maximum positive pressure value of the MEP and the minimum sound pressure value of the MIP are selected among the three or more attempts. 2) Using the MVV (maximum volitional ventilation) Digital spirometer (Pony FX, COSMED Inc., Italy) machine, repeat breathing deeply and quickly for 12 seconds while wearing a nose plug, and multiply it by 5 to obtain the L/min value. (2) Measure the values of the Pneumatic ventilation. · FVC (forced vital capacity): Total expiratory volume of one of the maximum effort gases · FEV1 (forced expiratory volume 1, effort expiratory volume): Ejected expiratory volume of the first second of the maximum effort expiratory volume (FEV1/FVC): FVC ratio, percentage of FVCs, and extraction of the FVC (excessive flow). PEF): Highest speed of effort opportunity
The primary cause of the complex interaction of chronic pelvic pain originates from the visceral organs in the pelvic cavity, and it has been observed that musculoskeletal dysfunctions (such as increased muscle activity in the pelvic floor muscles) are often accompanied by visceral painful stimuli in the pelvic region as a result of shared innervation and visceral-somatic convergence. This study aims to investigate the effect of breathing exercises combined with pelvic floor exercises on pain, pelvic floor muscle activity, psychological factors, and quality of life in women with chronic pelvic pain.
This clinical research study will investigate the dose of inspiratory muscle strength training needed to maintain cardiovascular adaptations induced by a six-week loading dose.
Respiratory muscle dysfunction is highly prevalent in patients with prolonged weaning from mechanical ventilation and is strongly associated with weaning failure. Efforts to strengthen the respiratory muscles, aimed at reversing or minimizing the impact of respiratory muscle weakness on clinical outcomes, have generally focused on the diaphragm with specific inspiratory muscle training (IMT) exercises. However, the effectiveness of these exercises and impact on clinical outcomes are not current practice in the majority of ICUs, as they are hardly feasible in ICU patients who often cannot be disconnected from the ventilator and cannot fully cooperate. Promising results have been published concerning non-respiratory training techniques, which can also target the accessory muscles, particularly important in the presence of increased load to the respiratory system, as in the case of the weaning phase. These non-respiratory training techniques would have the advantage of not entailing disconnection of the patient from the ventilator. In particular, in healthy subjects, a quasi-isometric neck contraction, called neck flexion, appeared to generate greater or comparable recruitment of some principal and accessory muscles of respiration, when compared to conventional IMT. However, this has not been studied in patients requiring prolonged mechanical ventilation, for whom IMT with threshold loading devices remains the primary recommended rehabilitation strategy. Therefore, the primary aim of the investigators is to assess the feasibility, tolerability, and safety of neck flexion and to compare them with IMT technique in patients with difficult and prolonged weaning from mechanical ventilation. Secondary aims are: i) to characterize which respiratory muscles are recruited and their level of activation at different levels of ventilatory assistance and ii) to assess which respiratory muscles are recruited and their level of activation during the two techniques and to compare these findings. The hypothesis of the investigators is that neck flexion will be feasible (more than conventional IMT), well tolerated, and safe in patients with difficult and prolonged weaning. The investigators also hypothesize that, reducing the level of assistance and during unassisted breathing, a progressively increasing activation of the diaphragm, neck and trunk respiratory muscles, reflecting increased ventilatory load, will be fund. Finally, the hypothesis of the investigators is that the level of muscle activation/recruitment during neck flexion will be comparable or even greater to that occurring during IMT, as found in healthy subjects. Finding a new and highly feasible rehabilitative technique, able to recruit and train the respiratory muscles (including accessory muscles), will have the potential to promote patients' weaning and improve all related clinical outcomes, and therefore to dramatically shift the paradigm about the role of rehabilitation in ICU.

The goal of this four-part preclinical [I-II] and clinical [III-IV] trial is to compare, with randomised crossover study design [I-IV], a new medical airway device with standard procedure (biteblock or no device) for upper airway patency during sedation with intravenous propofol [I-IV]. - Page 1 of 9 [DRAFT] - The two main questions it aims to answer are if this new airway device is superior to standard procedure with respect to - maintenance of spontaneous ventilation [I] and upper airway volumes [II] at moderate and deep steady-state levels of sedation in healthy volunteer study participants, and - fewer and less lasting bedside signs of respiratory depression [III-IV], and less adjuvant use of manual airway support [III-IV] during procedural sedation (PS) according to standard of care(SOC) in study patients scheduled for colonoscopy or ureteral catheterisation under PS. Owing to the crossover study design used throughout the trial, there are no comparison groups of study participants [I-II] or study patients [III-IV].
The goal of this experimental study is to test the effects of Music Breathing (MB) in promoting a sense of coherence among young people. The main questions it aims to answer are: - What is the effect of a MB programme on personal resources (i.e., SOC, coping self-efficacy, emotion regulation and mindfulness) compared with the control condition in young people? - What is the effect of a MB programme on stress reduction (i.e., depression, anxiety and stress, and salivary cortisol levels) compared with the control condition in young people? • • What is the effect of a MB programme on mental well-being compared with the control condition in young people? - What is the relationship between SOC, coping self-efficacy, emotion regulation and mindfulness? Participants will receive a MB programme in 6 weekly sessions and weekly home practice. The programme includes: - meditative breathing; - breathing with music listening; - drawing a mental image of the breathing practice; and - sharing and processing of the experience
