Filter by:An observational study will be conducted in 20 hospitalized surgical patients routinely managed with opioids for anesthesia and post-operative pain control. Trachea Sound Sensor measurements and reference respiratory measurements will be recorded and analyzed to develop diagnostic algorithms that produce a risk-index score that detects/predicts progression from mild hypoventilation, to moderate hypoventilation, to severe hypoventilation due to opioids and other medications that cause respiratory depression. Our current Trachea Sound Sensor (TSS) has a wired Sony commercial microphone integrated into a commercial pediatric stethoscope, coupled to the skin surface over the trachea at the sternal notch. The Trachea Sound Sensor will measure and record the sounds of air moving within the proximal trachea during inhalation and exhalation. The microphone signal will be converted into an accurate measurement of the patient's respiratory rate and tidal volume (during inhalation & exhalation) over time, to determine the minute ventilation trend, breathing patterns, apnea episodes, and degree of snoring (due to partial upper airway obstruction). A commercial respiratory facemask and two pneumotachs (gas flow sensors) will also be used to accurately and continuously measure the patient's respiratory rate and tidal volume (during inhalation & exhalation) to determine the minute ventilation trend, breathing patterns, and apnea episodes. TSS data and reference respiratory data will be collected prior to surgery with the patient breathing normally (baseline), in the Operating Room (OR) during the induction and maintenance of anesthesia, in the Post Anesthesia Care Unit (PACU), and on the general nursing floors of Thomas Jefferson University Hospital (TJUH). The sounds of air flowing through the proximal trachea will be correlated with the reference breathing measurements using signal processing methods to optimize the measurement accuracy of RR, TV, breathing pattern, apnea episodes, and degree of snoring. A commercial accelerometer may be coupled to the skin surface of the neck (with tape) to measure body position and activity level. The TSS and vital sign trend data will be analyzed to produce a Risk-Index Score every 30 seconds with alerts and alarms that warn the patient and caregivers about progressive Opioid Induced Respiratory Depression (OIRD).
This is a prospective multicenter randomized control trial to assess percentage mask leak six months post instructor led positive pressure ventilation skills training in providers who undergo booster training compared to those who do not undergo any booster training
The purpose of this study is to evaluate the effects of several manual therapy techniques on autonomic nervous system and to compare it with other groups in the study such as deep-slow breathing group and the control group. The measurements will take place right before and after the intervention to evaluate the effects of one single intervention.
Obesity hypoventilation syndrome (OHS) is defined as a combination of obesity [body mass index (BMI) ≥30 kg/m2], chronic daytime hypercapnia (PaCO2 >45 mm Hg), and sleep-apnea in the absence of other known causes of hypercapnia. Respiratory system compliance decreases and resistance increases in OHS. This causes increase in work of breathing and oxygen cost of breathing, which may result in respiratory muscle fatigue. Increase in respiratory workload and increase in resistance to respiration is expected to decrease in respiratory muscle endurance (RME) in subjects with OHS.
The data were retrospectively collected during the first and the second wave of epidemic in COVID-19 patients with Severe Acute Respiratory Syndrome Coronavirus 2, at the moment of intensive care unit admission and during the in intensive care unit staying.
Comorbidities associated with severe obesity determine an important public health problem. Few methods are considered potentially effective for the treatment of severe obesity and the clinical relevance of bariatric surgery is growing, as well as the number of procedures performed. The insertion of the physiotherapist in the multiprofessional team responsible for performing the surgical procedure is essential from the preoperative screening and evaluation to the prevention and treatment of postoperative complications. Therefore, the physiopathological aspects involved with severe obesity, the technical aspects and risks of the surgical procedure, as well as the physiotherapeutic techniques that have scientific proof must be known by the physiotherapist responsible for the surgical follow-up of the patient. In this context, the use of non-invasive ventilation (NIV) in the postoperative period of bariatric surgery has ample therapeutic potential. The present research project aims to evaluate the immediate prophylactic use of NIV on the respiratory and functional recovery of the patients.
The ETAPES Program, a French national Experimentation in Telemedicine for the Improvement of Healthcare Pathways, was launched in 2018 for 4 years. Its objectives were to provide a temporary public reimbursement for medical telemonitoring in order to determine the benefits for the patient and the impact on medical organization and healthcare costs. In particular, this program applies to patients suffering from hypercapnic chronic respiratory failure and requiring home non invasive ventilation (NIV). For these patients, the ETAPES program combines NIV telemonitoring and therapeutic education. e-VENT study aims at evaluating the ETAPES program, implemented using the Chronic Care Connectâ„¢ telemonitoring solution, versus Standard of Care, on the effectiveness of home NIV, measured by average PtCO2, reflecting the level of nocturnal alveolar hypoventilation.
Home sleep studies - which allow the measurement of breathing while the person sleeps - will be performed on patients with fibrotic interstitial lung disease attending two of the UK's largest respiratory medicine services.The study will investigate at how symptoms, and breathing and exercise tests differ between these two groups after 12 months of study.
This study focuses on a comprehensive examination of obese patients with sleep-related breathing disorders including patients with OSA, sleep hypoventilation and OHS. The aim of this study is to (1) evaluate characteristics of and differences between severity levels of obesity-related breathing disorders, (2) discuss pathophysiological variables associated with hypoventilation during sleep or at daytime and (3) find functional parameters indicating sleep hypoventilation.
Various guidelines for endotracheal intubation (insertion of breathing tube for mechanical ventilation) of Coronavirus Disease 2019 (COVID-19) patients recommend the use of videolaryngoscope (medical device used for intubation that has a camera to visualize the vocal cords between which the breathing tube will pass) over direct laryngoscope (conventionally-used medical device for intubation that depends on anesthetist's direct visualization of vocal cords). The reasons for this recommendation are to maximize the distance between the medical personnel and the patient's face during intubation to decrease the risk of viral particles transmission and to improve intubation success. For patients infected with COVID-19, Powered Air Purifying Respirator (PAPR) is recommended as an alternative to N95 masks during aerosol-generating procedures such as intubation because N95 masks may not fully protect medical personnel from viral transmission during intubation. There is no evidence to suggest that videolaryngoscope (VL) is superior to direct laryngoscope (DL) for intubation when PAPR is donned. The purpose of this study is to determine if McGrath VL is superior to DL for intubation when the anesthetist is wearing a PAPR. The investigators' hypothesis is that McGrath VL will decrease the time to intubation by 20 seconds and more compared to DL when PAPR is donned. The investigators also hope to learn if there is any difference in the difficulties encountered between the use of VL and DL.
