27 Clinical Trials for Various Conditions
This study evaluates the performance of eight (8) cleared capnography carbon dioxide (CO2) sampling filterlines during patient simulated scripted activities when connected to a Medtronic (MDT) dual parameter monitor.
This study will provide capnography monitoring during routine upper endoscopy and colonoscopy with moderate sedation in order to see if it improves safety.
The purpose of this study is to evaluate the use of Capnography (Continuous recording of the carbon dioxide content of expired air)as an alternative test to measure PC02 levels in patients with asthma, chronic obstructive pulmonary (COPD,interstitial lung disease(ILD)or coronary disease who are at risk of intubation.
Subjects undergoing elective ERCP and EUS will receive standard monitoring and sedation. In addition, capnography which measures carbon dioxide levels and can graphically assess respiratory activity will be used. Subjects will be randomized to either a capnography blinded or titration arm. In the capnography titration arm, the endoscopy team would be made aware of capnographic abnormalities as they arise throughout the procedure. In the capnography blinded arm, this information will not be available to the endoscopy team and represents standard of care. It is our hypothesis that using capnography can prevent low oxygen levels known as hypoxemia, during these procedures.
The purpose of this study is to compare the accuracy of EtPCO2 measurements taken with a nasal cannula using the Microcap (Oridion Capnography Inc., Needham, MA) micro-stream device and the TG-920 main-stream device (Nihon Kohden, Tokyo, Japan). Three groups of non-intubated, spontaneously breathing patients will be included: 1) lean patients without obstructive sleep apnea (OSA); 2) obese patients without OSA; and 3) obese patients diagnosed with OSA. This latter group has a higher prevalence of oral breathing. Additionally, to test the efficacy of oral guides, we propose to compare the accuracy of EtPCO2 measurements from the Microcap with two different nasal cannulas, one with (Smart CapnoLine PlusTM, Oridion Medical, Jerusalem, Israel) and one without (CapnoLineTM H, Oridion Medical) an oral guide to trap gas expired from the mouth. The TG-920 main-stream system requires its purpose-designed YG-122T cannula so that is the only one that will be tested with the Nihon-Kohden product.
The aim of this study is to increase the detection of undiagnosed obstructive sleep apnea (OSA) and secondly to increase the sensitivity for detection of respiratory depression (\< 6 breaths per minute) in post operative patients on the general care nursing unit.
The purpose of this study is to assess if capnography can be utilized to assist in the process of endotracheal intubation; specifically, in locating the glottic opening. Ultimately this would result in a new use of capnography to aid in securing normal and difficult airways. Currently capnography is only utilized for the confirmation of endotracheal tube placement. If successful, this study will provide information, and allow for the development of instrumentation that will assist in difficult airway management; specifically, in locating the glottic opening when visualization may be impaired. Ultimately, this technique will be useful for routine and emergency airway management.
This study will compare the sensitivity and specificity of waveform capnography versus colorimetric carbon dioxide detection to identify tracheal placement of the endotracheal tube during intubation of critically ill adults.
The goal of this clinical trial is to compare the performance of a novel non-invasive respiratory monitoring system against the gold standard methods (capnography) in human subjects. The main question it aims to answer is whether the novel monitoring system comparable to the current standards.
1. Determine agreement (accuracy) of resting heart rate measured by Vitalpercept when compared to an FDA-cleared electrocardiograph (ECG) device, LifeSignals Wireless Biosensor. 2. Determine agreement (accuracy) of resting respiratory rate measured by Vitalpercept when compared to an FDA-cleared capnographer, Capnostream 20.
This pilot study is part of a phased approach to refine, optimize, and test the feasibility of CALM Breathing. Preliminary participant feedback from the Capnography-Assisted Respiratory Therapy (CART) study was applied to adapt and design CALM Breathing (including its dose, schedule, delivery, and home program). This pilot builds on initial lessons learned and identifies intervention areas still needing greater development to assure the success of a future large trial, targeting a subpopulation at risk, that is, those with COPD and anxiety sensitivity.
To understand if a progressive increase in end-tidal carbon dioxide (CO2) levels are heralding respiratory difficulties before desaturation measured from capnography in obstructive sleep apnea patients, with the use of nasal prongs, transcutaneous monitors, Capnostream, and Massimo technologies.
A. Determine if Respiratory Volume Monitor (RVM) can be used during procedural sedation to adequately monitor patient's respiratory status as compared to capnograph Aims B. Compare the time of capture of respiratory events (depression, arrest, etc...) on both the RVM and the capnograph C. Compare the incidence of missing or poor quality readings between the RVM and the capnograph D. Compare RR readings between the RVM and the capnograph (during periods with adequate data quality on both devices) E. If RMV can identify respiratory obstruction. Capnography
The purpose of this study is to explore how the End Tidal Carbon Dioxide monitoring via nasal cannula (ETCO2-NC) device may allow for earlier detection of respiratory complications. This device will detect the amount of carbon dioxide exhaled with each breath and may better predict high levels of this than traditional monitoring. This may reduce the number and severity of respiratory issues. A convenience sample of 60 participants either scheduled for continuous flow left ventricular assist device (CF-LVAD) implant or who have been readmitted to an ICU with a CF-LVAD will be recruited and randomized to usual care or usual care plus ETCO2-NC throughout their stay in the ICU.
PRODIGY is a prospective, multi-center, post-market, international cohort study. The primary objective of this study is to derive a score to identify subjects at risk to have respiratory depression (RD) episodes in patients undergoing opioid therapy in the hospital ward and monitored by capnography. The score will be derived by using subjects within the derivation cohort and internally validated using subjects within the validation cohort. The primary endpoint used to derive the score will be the occurrence of RD episodes derived by Capnostream 20p device memory data combined with clinical data and validated by an independent Clinical Endpoint Committee (CEC) during the study course.
Multi-center observational trial with study device blinded in order to assess in parallel standard monitoring and intervention practices related to management of respiratory compromise in the post-anaesthesia care unit (PACU)
The investigators hypothesize that the addition of capnography during moderate sedation will improve recognition of hypoventilation and apnea. This will lead to an increased frequency of staff interventions such as verbal or physical stimulation for these events in order to improve ventilation which will in turn lead to a reduction in the frequency of oxygen desaturations. If capnography proves to be effective in creating earlier detection and intervention for hypoventilation and apnea during moderate sedation provided by non-anesthesiologists, this device can be used in a variety of clinical settings to enhance patient safety.
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.
Investigators will enroll 320 patients who will undergo non-cardiac surgery, receive supplemental oxygen via face mask, and will be on a continuous pulse oximetry monitor in the Post Anesthesia Care Unit (PACU). The enrollment criteria were adapted from a previous study that showed SpO2 values seriously underestimated the severity of post-operative hypoxemia in patients with and without specific risk factors for hypoxemia. Research personnel will screen and ensure that each subject meets the enrollment criteria, and the informed consent is properly executed. Upon arrival to the PACU, each subject will be fitted with oxygen mask containing the Linshom sensor, which will be connected to a Linshom monitor for data collection. A side stream capnography line will be connected to the same face mask and the capnography data will be collected on the Zoe Medical 740 SELECT™ monitor. Additionally, two pulse oximeters will be applied to the same hand (non- NIBP arm), one of which will be connected to a hospital monitor (SoC) and the other to a Zoe Medical 740 SELECT™ monitor. The Linshom and 740 SELECT™ monitors will collect data once every second. Research personnel will then initiate the Linshom CPRM baseline mode and begin recording any clinical intervention (e.g., medications, oxygen delivery change, and stimulation upon detection of changes in patient's condition) that is performed by the PACU staff, paying close attention to, and recording of time at which those interventions occurred. Data collection will be performed throughout the subject's entire PACU stay. The CPRM data collection will be performed passively while the patient is monitored via SoC and will not interfere with clinical interventions that may take place during the data collection. Clinical staff in the PACU will be blinded to the Linshom CPRM data as well as pulse oximetry (non-SOC monitor) and capnography data collected.
This study will compare the data from pulse oximeters to capnographers as they are used to monitor patients who are being observed in the Emergency Department for a suspected overdose of alcohol or other drugs. The investigators will compare monitor data from patients who are and are not on supplemental oxygen, the ability of the monitors to predict the occurrence of airway interventions, and to detect ventilator changes noted on the opposing monitor. There will not be any interventions during this study other than the collection of data from the monitors and observation of the care of patients.
The purpose of this study is to determine whether a relationship exists between EtCO2 and carboxyhemoglobin levels in carbon monoxide exposure. Our hypothesis is that a liner relationship exists between EtCO2 and carboxyhemoglobin in carbon monoxide poisoning.
This research study will test the comfort of two noninvasive respiratory monitoring sensors (the connection to a monitor worn by a person-not the monitor). The two sensors, Masimo Rainbow Acoustic Monitoring sensor and Oridion Smart Capnoline Plus H sensor, are cleared by the U.S. Food and Drug Administration (FDA) and currently used in the clinical setting. People who enter into the study will wear the two interfaces, one after the other, for 20 minutes each (10 minutes with a small flow of air to the nostrils and 10 minutes without) and rate the comfort of each with a seven question survey. A total of 30 participants will be recruited.
Emergency department patients receiving opioid pain medicine such as morphine, fentanyl or Dilaudid are eligible. After medication exhaled carbon dioxide is measured. and recorded.
This will be a randomized trial of propofol versus the combination of propofol and ketamine for procedural sedation for procedures in the Emergency Department (ED). Propofol produces sedation, hypnosis, and dense amnesia, and is commonly used in the ED at Hennepin County Medical Center (HCMC) for procedural sedation. Ketamine is a dissociative anesthetic that is also frequently used in the ED in children and sometimes in adults. It has been proposed that by combining the two agents, the negative side effects of respiratory depression and hypotension associated with propofol, and the negative effects of dysphoria and vomiting associated with ketamine, can be avoided. In the proposed study, patients seen in the ED who will require procedural sedation for a painful procedure will be randomized to receive either propofol or propofol and ketamine. During the procedure, patients will be monitored per the standard of care, including use of a cardiac monitor, non-invasive blood pressure monitoring, pulse oximetry, nasal sample end-tidal carbon dioxide, and physician assessment. Once the procedure is successfully completed and the patient has returned to his/her baseline mental status, the patient will be asked to mark a 100 mm visual analog scale regarding perceived pain during the procedure, memory of the procedure, and overall satisfaction with the procedure.
This study is designed to determine the incidence and severity of respiratory depression in elective cesarean section patients who have received a spinal or epidural narcotic called duramorph for management of postoperative pain. A monitoring device called a capnograph as well as a device called a pulse oximeter is placed on the patient once in the recovery room after delivery. The capnograph monitors the carbon dioxide level that the patient breathes out as well as their respiratory rate. The pulse oximeter is a device that is taped on the patient's finger and measures their oxygen saturation level. The monitoring is maintained for 18-24 hours after surgery.
A pulmonary embolism (PE) is a blockage in one of the arteries of the lungs, and is usually caused by a traveling blood clot. The D-dimer blood test is currently used to diagnose PEs, but it is not always accurate for individuals who have recently undergone surgery or who have inflammatory-provoking diseases. The purpose of this study is to evaluate the effectiveness of the Carboximeter, a new PE diagnostic device that measures carbon dioxide (CO2) and oxygen (O2) output, in individuals at risk for developing PEs.
Investigators intend to determine if the use of Biphasic Cuirass Ventilation (BCV) improves patient safety (avoiding hypoxia) during emergency rapid sequence intubation .
