This study pretends to evaluate the potential use of Hyfe Cough Tracker (Hyfe) to screen for, diagnose, and support the clinical management of patients with respiratory diseases, while enriching a dataset of disease-specific annotated coughs, for further refinement of similar systems.
Background: The COVID-19 outbreak has strained the health care system. New tools are needed for diagnostic testing and monitoring of people who have the virus. Researchers want to test a device they hope can screen, detect, and monitor symptoms linked to respiratory diseases like COVID-19. Objective: To evaluate and validate a device that measures breathing, body temperature, heart rate, and tissue oxygenation. Eligibility: Healthy adults ages 18 and older with no flu-like symptoms and no current signs of infection, cough, fever, or sneezing. Design: Participants will have a physical exam. Their vital signs will be taken. Participants will sit in a chair. They will be monitored for 60 to 80 minutes while they do the following tasks: Rest for 10 minutes. They will repeat this after each task. Hold their breath for up to 2 minutes and then rest for 2 minutes. They will do this task 3 times. Pace-breathe with breathing rates of 10, 20, and 30 breaths per minute. They will do this task 2 times. Breathe air that has 5% of carbon dioxide for 5 minutes. During these tasks, data will be collected and recorded with a pulse oximeter, thermometer, respiratory belt, and spirometer. Participants will fill out questionnaires related to their daily activity (medication intake, exercise, smoking, and drinking). Participation will last for 2 to 3 hours.
Vojta therapy is a physiotherapy intervention with scientific evidence in respiratory pathologies in children and proven in adults. In this pilot study with an RCT design, its effect in adult patients with respiratory pathology caused by the SARS-CoV-2 virus will be studied. The non-invasive and non-painful technique consists of applying tolerable pressure to specific areas of the patient's body. The objective is to activate, in a reflex way, the ventilatory physiology. It is compared with the conventional respiratory physiotherapy approach.
Aspirin-Exacerbated Respiratory Disease (AERD), although uncommon in the general population, is an important phenotype of severe asthma and nasal polyposis where it occurs in 15% of severe asthmatics, and up to 30% of those with nasal polyposis. An important therapy for AERD is aspirin therapy after desensitization (ADAT). This is an inexpensive and proven therapy to improve the burden of sinus disease in AERD. Aspirin desensitization is the mechanism by which tolerance is induced in AERD patients. This is a 1-2 day outpatient procedure whereby increasing doses of aspirin are administered and the patients invariably experience some degree of hypersensitivity reactions. It is important to understand the effect of medications on the aspirin desensitization. It is known that the leukotriene modifier medications decrease the severity of the reactions in AERD. Other treatments such as antihistamines and the biologic agent omalizumab might have an effect on either blocking or blunting reactivity in AERD during desensitization. Dupilumab is a new respiratory biologic approved for atopic dermatitis, eosinophilic asthma and nasal polyposis. As such, it is well situated to be used for many AERD patients whose disease cannot be well controlled. The effect of dupilumab on the aspirin desensitization process and reaction is unknown and is the topic of this investigation. The primary objective is to determine the effect of dupilumab on reactions during aspirin challenge/desensitization.
The study presents an alternative method of tracheal dilatation in pediatric patients with acquired tracheal stenosis. Dilatation is performed by the use of balloon catheter connected with manometer, that is bronchoscopic guided into trachea in the stenotic area, through the wide canal of supraglottic device i-Gel. Every dilatation cession consists of three consequent tracheal balloon dilatations of maximum 3 minutes duration each, followed by 10-15minutes interval of controlled ventilation. The balloon is inflated for 60 seconds to reach predefined pressure, and then deflated. This method is minimal traumatic for tracheal mucosa, and application of several dilatation procedures every 2-3months, in pediatric patients with acquired tracheal stenosis, may lead to a relative reopening of trachea and recession of clinical symptoms.For the right performance of the dilatation procedure, patients receive general anesthesia with cessation of spontaneous ventilation. During procedure, controlled ventilation-oxygenation is impossible, because the i-Gel canal is occupied by bronchoscope and balloon catheter, so patients will remain apneic for a short period of time. For pediatric patients is important to perform proper preoxygenation prior to procedure, and to maintain oxygenation as long as possible during procedure. This is achieved by application of apneic oxygenation, through a small catheter, connected to high flow oxygen. Participants are exposed during first dilation to no oxygenation, while during second and third dilatation to apneic oxygenation. Aim of the study is to investigate primarily whether application of apneic oxygenation, in pediatric patients during tracheal balloon dilatation, maintains regional cerebral oxygen saturation rSO2 in significant higher levels, compared with no application of oxygenation. rSO2 levels are a sensitive index of oxygenation efficacy of the brain, accordingly this refers to a safe procedure. Secondary issues are whether application of apneic oxygenation maintains pulse oximetry SpO2 and artierial oxygen partial pressure PaO2 in higher levels, and what are the effects on arterial carbon dioxide partial pressure PaCO2 and on haemodynamic parameters (heart rate, blood pressure), compared with no application of apneic oxygenation.
This study intends to compare the impact of chest physiotherapy applied with two different methods on physiologic parameters in children hospitalized in the intensive care unit. In the intensive care unit where the study was conducted, the patients who have a respiratory disorder and receive supplemental oxygen therapy with non-invasive mechanical ventilation or an oxygen mask are first administered an inhaler drug therapy placed in the physician's order. It is followed by chest physiotherapy and then oropharyngeal and nasopharyngeal aspiration. However, in practice rendered by the researcher, it is suggested that when chest physiotherapy and aspiration are administered in the first place and then followed by an inhaler drug therapy, it might have a more positive impact on the patient's physiologic parameters. For this reason, it is intended to compare the efficiency of chest physiotherapy applied in a different order.
Ventilated neonates frequently require supplementary oxygen to allow for adequate oxygen delivery to the tissues and normal cell metabolism. Oxygen treatment should be monitored carefully as both excessive and inadequate dosing can have detrimental effects for the infants. Hypoxia (giving too little oxygen) increases mortality and later disability whereas hyperoxia (giving too much oxygen) increases the risk of complications such as retinopathy of prematurity and lung disease. Although very preterm and low birth weight infants represent the majority of ventilated neonates, more mature infants may also require mechanical ventilation at birth and provision of supplementary oxygen. Therefore, they may suffer from complications related to hypoxia or hyperoxia. Hence, their oxygen saturation levels and the amount of the inspired oxygen concentration provided should be continuously monitored. Oxygen control is traditionally monitored and adjusted manually by the nurse looking after the infant. Closed-loop automated oxygen control (CLAC) is a more recent approach that involves the use of a computer software incorporated into the ventilator. The software uses an algorithm that automatically adjusts the amount of inspired oxygen to maintain oxygen saturation levels in a target range. Evidence suggests that CLAC increases the time spent in the desired oxygen target range, decreases the duration of hypoxia and hyperoxia and reduces the number of manual adjustments required by clinical staff. However previous studies have been limited to very small infants. With this study the investigators aim to evaluate the effectiveness of CLAC in ventilated infants born at 34 weeks gestation and beyond. The achievement of oxygen saturation targets and the number of manual adjustments required will be compared between periods of CLAC and manual control in a cohort of patients that has not been included in previous studies and could also benefit from the intervention. The investigators will also evaluate if CLAC reduces investigations performed to ventilated babies(blood gases, X-rays).
