Filter by:It is estimated that 1,275,000 people in the United States alone live with spinal cord injury, including around 100,000 Veterans with spinal cord injury, making the V.A. the largest integrated health care system in the world for spinal cord injuries injury care. New therapies are needed to prevent the morbidities and mortalities associated with the high prevalence of respiratory disorders in Veterans with spinal cord injury. The current research project and future studies would set the base for developing innovative therapies for this disorder. This proposal addresses a new therapeutic intervention for sleep apnea in spinal cord injury. The investigators hypothesized that daily hypercapnia treatments improve respiratory symptoms and alleviate sleep apnea in patients with chronic spinal cord injury. The investigators will perform a pilot study to examine the impact of daily hypercapnia treatments for-two week durations among Veterans with spinal cord injury. The investigators believe that this novel approach to treating sleep apnea and will yield significant new knowledge that improves the health and quality of life of these patients.
High flow nasal cannula (HFNC) is used in interventional procedures to prevent hypoxia during sedation. In patients with a patent airway, HFNC reduces dead space ventilation as well. It is unknown if dead space ventilation is also reduced by HFNC in an EndoBroncheal UltraSound procedure, in which the airway is partially blocked by the endoscope. Especially in patients with Chronic Obstructive Pulmonary Disease (COPD) the partial blocking of the airway may reduce ventilation. If HFNC is able to reduce dead space during an EBUS-procedure, it may facilitate CO2 clearance, which may lead to a reduction in work of breathing. This study aims to investigate if HFNC reduces dead space ventilation in patients undergoing an EBUS-procedure and if this is flow-dependent. A randomized, double-blinded, cross-over study is designed.
We hypothesized that patients with mild hypercapnia during anesthetic emergence after TIVA had a shorter recovery time than patients with normal blood carbonate levels. We will select patients undergoing transurethral lithotripsy, who were expected to have mild postoperative pain, compare tracheal extubation time in patients with normal blood carbonic acid level and mild hypercapnia, to evaluate the effect of blood carbonic acid level during anesthetic emergence on recovery time from TIVA by. We also examined the changes of cerebral blood flow by TCD to investigate the possible mechanism of mild hypercapnia affecting the recovery time from TIVA.
The objective of this study is to assess the efficacy and safety of this new Prismalung+ membrane in its intended clinical setting by demonstrating a reduction in ventilatory parameters and pulmonary energy load or the successful maintenance of spontaneous breathing, respectively, the absence of the need to initiate vv-ECMO therapy, and initial survival.
The Autonomic (or "automatic") Nervous System (ANS) regulates internal processes, including control of heart rate and blood pressure (BP). When someone stands, and gravity tries to pull blood away from the brain, the ANS works to maintain BP and brain blood flow. Neurogenic Orthostatic Hypotension (NOH) occurs when our "fight-or-flight" part ("sympathetic") of the ANS fails. BP can drop a lot when upright, reducing blood flow and oxygen delivery to the brain, and this can cause symptoms of light-headedness, nausea, and fainting. One solution to help counter the effects of NOH may be to increase sympathetic activity by breathing higher levels of carbon dioxide. In healthy volunteers, small increases in the amount of inhaled carbon dioxide has been shown to increase BP in the upright position, and this improves symptoms! The objectives of the current study are to apply carbon dioxide in patients with NOH and healthy controls to: (a) evaluate the effects of breathing carbon dioxide on BP and brain blood flow, and (b) determine if a device that increases carbon dioxide while standing will work as a new therapy
aim of this research is to evaluate the effects of FFP2/N95 masks on peripheral oxygen saturation and pulse rate in dental professionals
Domiciliary non-invasive ventilation (NIV) is a standard care for improving survival rates of selected patients with chronic hypercapnic respiratory failure (CHRF) and to improve the patients' hypercapnia, sleep quality, health-related quality of life (QoL). Adherence is an important factor affecting clinical effectiveness of domiciliary NIV. Our previous study has noted the associations between poor domiciliary NIV adherence and increased number of clinical adverse events (p = 0.004) and increased hospitalization requiring acute NIV salvage (p = 0.042). However, there are very limited studies on adherence to domiciliary NIV in patients with CHRF. The only interventional study was a single-group pre-test post-test study and lack of a theoretical framework for guiding the intervention. This study is employing an Information-Motivation-Behavioral skills (IMB) model-based intervention to improve inhalation adherence in a group of chronic obstructive pulmonary disease (COPD) patients.
This study will describe influence of NHF or NIV to different ultrasonographic parameters of the diaphragm. Therefor subjects will be randomized to the sequence NHF and than NIV or NIV and than NHF. In all subjects same parameters will be evaluated.
Single-center retrospective study conducted on a population of patients with chronic hypercapnic respiratory failure treated by non-invasive ventilation at home, followed at the CHRU of Nancy. The objective is to assess the contribution of reading the NIV card with a standardized grid in their follow-up. The main objective is to assess the inter-observer agreement of a standardized NIV card reading grid, the secondary objective is to compare the results of NIV card reading between the usual NIV card reading method in the service and this same method completed by the addition of the standardized reading grid. The hypothesis is that the use of a standardized NIV card reading grid improves patient follow-up by standardizing their care.
Objective of the study is to assess the safety and efficacy of CO2 removal by the multiECCO2R (CO2 Removal System) on the multiFiltrate/multiFiltrate Pro in veno-venous extracorporeal circulation during continuous renal replacement therapy (CRRT) in patients presenting with hypercapnia due to acute lung failure and acute kidney injury.
