Filter by:Incentive spirometry is a method to stimulate deep breathing and maximum sustained inflations, which provides participants with visual feedback on the inspiratory volume achieved, favoring lung inflation. Its multiple benefits and ease of use favor adherence, making it a common device used in the clinical environment. This device is used in pathologies or procedures that can cause decreased function and respiratory mechanics, such as thoracoabdominal surgeries, and is indicated to reduce the incidence of postoperative pulmonary complications. It is also indicated in the presence of pulmonary atelectasis or conditions that predispose to the development of pulmonary atelectasis, in patients with prolonged bed rest, patients with neuromuscular disease, patients with spinal cord injury, and patients undergoing coronary bypass, among others. In 2004, students from the Universidad del Valle carried out an investigation whose result was the creation of the Incentivo Modificado de Pachon, a handcrafted design device that allows mobilizing flows ranging from 600 CC/sec to more than 1400 CC/sec, which characterizes it as a flow respiratory incentive. In 2020, the device obtained the endorsement of the Superintendence of Industry and Commerce, however, to date no studies have been carried out that objectively verify the effect that the modified Pachon's incentive (Incentivo Modificado de Pachon by the name in Spanish) has on the distribution of ventilation in comparison with another Branded respiratory incentive. Electrical Impedance Tomography is a diagnostic tool that, employing a belt of electrodes connected around the user's chest, uses the electrical characteristics of the tissue, to provide information in a non-invasive, continuous way, on foot. bedside and radiation-free on pulmonary ventilation and perfusion, as it allows repeated imaging of tidal volume distribution, as well as distinguishing the characteristic regional filling and emptying of each lung, all in real-time and safely. In this study, the distribution of pulmonary ventilation between the modified Pachon's incentive vs. another Branded respiratory incentive will be compared, through electrical impedance tomography, in a healthy population of the city of Cali. The hypothesis to be tested is that the distribution of Pulmonary ventilation measured by Electrical Impedance Tomography is similar between the modified Pachon's incentive and another Branded flow respiratory incentive.
This is a prospective observational trial. The purpose of this study is to explore the feasibility of EIT monitoring pulmonary blood flow and the consistency and difference between EIT monitoring pulmonary local ventilation blood flow and SPECT and CTPA monitoring methods
This study focuses on the evaluation of various factors repeatedly discussed in relation to the impaired sedation of intubated ventilated COVID-19 patients. The sedation response of >100 moderately to severely affected COVID-19 ARDS was evaluated. The sedation level was measured at the bedside using the Richmond Agitation and Sedation Scale and ventilator synchrony. The evaluation was performed according to the static evaluation plan with respect to age, storage therapy and organ failure.
Difficult Bag Mask Ventilation is well described in the anesthesiology literature, and bearded patients are likely to experience this phenomenon. This study involves application of a large and perforated Tegaderm® across the lower face of the bearded patient to quantify its effectiveness at improving mask ventilation in this anesthetized population.
The aim with this descriptive multicenter study is to examine the quality of the ventilation given by Emergency Medical Service (EMS) personnel during cardiopulmonary resuscitation (CPR). Primary endpoint is the ventilation quality measured as ventilation frequency, tidal volume and minute ventilation. This will primarily be studied during CPR with a 30 compression/2 ventilation ratio performed by the EMS personnel where the airway is managed with a supraglottic device but also in CPR with continuous ventilation (8-10 breaths/minute) after the airway management have been replaced with an endotracheal within the emergency room. The inclusion of patients will be performed at two sites (Uppsala; Sweden and Utrecht; Holland), all out-of-hospital cardia arrest (OHCA) patients will receive care according to current CPR guidelines using mechanical chest compressions.
The Evone® ventilator is a new device capable of lung ventilation through a narrow-bore cannula, the Tritube.Two ventilation modes are possible: high frequency jet ventilation (HFJV) and flow-controlled ventilation (FCV). In this prospective pilot study the efficacy of FCV using the Evone® ventilator and Tritube is investigated when compared with Volume Controlled Ventilation (VCV) via a normal tracheal tube.
Brief Summary Short description of the protocol intended for the lay public. Include a brief statement of the study hypothesis. (Limit: 5000 characters) Example: The purpose of this study is to determine whether prednisone, methotrexate, and cyclophosphamide are effective in the treatment of rapidly progressive hearing loss in both ears due to autoimmune inner ear disease (AIED). This project is part of a research field on the role, not yet fully understood, of atmospheric pollution, especially from road traffic, on respiratory health and allergies, particularly on the development / onset of symptoms and functional disturbances. The ultrafine fraction of particles (UFPs - particles smaller than 100 nm in diameter) is of recent interest because of their ability to induce inflammatory effects, oxidative stress and may contribute to the exacerbation of asthma symptoms in susceptible individuals. UFPs, with their high number concentration and surface area and their small diameter are able not only to convey other contaminants, but also to contribute to a high deposition efficiency, into the alveoli in the lungs. Recently it appeared relevant to be interested in black carbon (BC), components of PM2.5 (particulate matter with a diameter less than 2.5 micrometers), suspected of being responsible for their toxicity. Current epidemiological knowledge of the effects of UFPs and BC are few as compared to those on fine particles. Some professionals, such as police, drivers (taxis, truckers ...), delivery men, postal workers, workers on roads and highways, etc. are heavily exposed, during their working hours, to air pollution due to road traffic. These occupational groups appear to be at greater risk for developing respiratory, cardiovascular and neurological diseases than the general population. Occupational exposure to diesel exhaust has been associated with an increased risk of lung cancer mortality and chronic obstructive pulmonary disease. Occupational exposure to UFPs and BC has rarely been measured due to a lack of suitable devices. Therefore, this project's originality consists in measuring UFPs and BC by using portable devices developed in the recent years. The use of these devices, linking their recordings with ventilatory measures and repeating them, offers the rare opportunity to study the short-term respiratory health impact of this occupational exposure, which has never been described in the literature. Our research aims to: 1/ quantify the occupational exposure of taxi drivers to UFP, BC, oxides of carbon (CO, CO2) and to nitrogen dioxide (NO2), 2/ identify spatio-temporal variability and patterns of exposure related to occupational tasks, 3/ study the impact of this occupational exposure to UFP and BC on ventilation performances and respiratory symptoms.
To discover whether different types of ventilation breathing tube influence ventilation effect of children/ neonate, the investigators analysis tidal volume, end tidal carbon dioxide, compliance among children and neonate under general anesthesia. The study compares eight ventilator breathing tube of different length, diameter, material of the ventilator breathing tube. Besides, the investigators also make an approach verify the change of body temperate under different gas flow(2L, and 5L).
Patients with indication of shoulder surgery will be submitted to ultrasound-guided interscalene brachial plexus block with 4ml or 15ml of bupivacaine- epinephrine 0,5%- 1:200,000 at level of C5-6 roots and will be evaluated their ventilation and pulmonary aeration by electrical impedance tomography
Many post-operative complications arise from patients who breathe inadequately. Inadequate respiration, whether the result of surgery or the anesthesia, causes a decrease in blood oxygen saturation and an increase in carbon dioxide partial pressure. Both of these surrogate measurements of respiration may pose a challenge to measure. Some administer exogenous oxygen to all patients as they leave the operating room in order to maintain the blood oxygen saturation. This renders the oximeter a less sensitive metric of depressed respiration. In the face of decreased respiration, the carbon dioxide levels continue to increase slowly and often go undetected unless blood gases are measured. Indeed carbon dioxide blood levels are the only metric to detect inadequate ventilation using this surrogate index. Monitoring ventilation is a serious challenge outside of critical care settings. In fact, there are no monitors available that can measure tidal volume or relative tidal volume outside of these settings. Linshom is a novel instrument that tracks relative respiration by measuring the excursions of the temperature swings between inspiration and expiration and normalizing them to the patient's breathing. This monitor may be the first non-invasive monitor to measure relative tidal volume in non-critical care settings. The purpose of this study is to determine whether a non-invasive, temperature-based respiratory instrument can track tidal volume (Vt) in patients. The investigators hypothesize that the Linshom device can accurately and consistently track tidal volume as measured by closed loop mechanical ventilator.
