Filter by:The primary objective of the prospective study is to compare the incidence, duration, and severity of oxygen desaturation in high-risk patients randomized to nasal mask with nasal positive airway pressure (PAP) or standard care (nasal cannula) receiving propofol sedation during colonoscopy in an ambulatory surgical center (ASC). Patients will be randomized in groups of ten to one of two groups using a random number table. Group A: standard care with a nasal cannula. Group B: SuperNO2VA™EtCO2. Following the procedure subjects will be asked to complete satisfaction surveys before leaving the ASC and 48 +/- hours following their procedure. Researchers will compare levels of satisfaction and levels of oxygen saturation.
International guidelines recommend giving positive pressure ventilation (PPV) by face mask to newborns who do not breathe or have a slow heart rate at birth. Preterm infants are at high risk of developing respiratory distress syndrome (RDS) and many are treated with continuous positive airway pressure (CPAP) in the neonatal intensive care unit (NICU). Though the majority of preterm infants breathe spontaneously at birth, many clinicians routinely apply a face mask to preterm infants shortly after birth in the delivery room (DR) to give them CPAP. However, applying a face mask may inhibit spontaneous breathing in newborns. In this study, premature babies will be randomly assigned to have a face mask routinely applied for CPAP shortly after birth; or to have a face mask selectively applied only for PPV if they are not breathing or have a slow heart beat in the first 5 minutes of life, or for CPAP if they have signs of respiratory distress after 5 minutes. The investigators will determine whether fewer participants who have the mask selectively applied receive PPV in the DR.
This trial investigates effects of individualized (by compliance guided pressure settings) flow-controlled ventilation compared to best clinical practice pressure controlled ventilation in cardiac surgery requiring cardiopulmonary bypass.
The purpose of this study is to determine the effectiveness of a non-invasive communication aid for BPAP/CPAP masks. This study also looks to determine the potential impact of the device on patients with obstructive sleep apnea (OSA) and the individuals that interact with the device.
Objective: The aim of this project is to evaluate how intra-abdominal pressure paired coupled with different ventilatory positive end-expiratory pressure levels affects the transpulmonary driving pressure during pneumoperiteneum insufflation for laparoscopic surgery. Methodology: Patients undergoing laparoscopic surgery will be included. The study will investigate the relationship between intra-abdominal pressure (IAP) and transpulmonary driving pressure (TpDp) and the effect of titration of PEEP on their relationship. At three different levels of intra-abdominal pressure, the respiratory driving pressure (RDp) and TpDp in each subject will be measured in each subject. The same subject will undergo two different ventilation strategies. Demographic data (height, weight, body mass index and sex), ASA physical status (surgical risk classification of the American Society of Anesthesiology), number of previous abdominal surgeries, number of previous pregnancies, and respiratory comorbidities will be collected. Respiratory pressures and mechanics will be recorded at each level of intra-abdominal pressure (IAP) during each ventilatory strategy. The variables recorded will include: airway pressures (Plateau pressure Pplat, Peak pressure, Ppeak), the final esophageal pressure of inspiration and expiration and pulmonary stress index. Mixed linear regression will be used to evaluate the relationship between different PEEP levels, IAP and TpDp by adjusting for known confounders and adding individuals as a random factor. Likewise, an analysis using a mixed linear regression model with the pulmonary stress index as a function of the intra-abdominal pressure, the ventilation regime, and a specific random intercept term for each subject will be performed.
This is a randomized trial to determine if a visible respiratory function monitor (RFM) displaying realtime measurements of delivered inflations improves clinical providers ability to perform positive pressure ventilation (PPV) within a pre-defined target tidal volume in preterm infants after birth.
Heart Rate Variability (HRV) analysis has been studied in the critically ill patients although it is affected by several uncontrolled variables in the clinical conditions. The aim of this trial is to measure the effects of mildly reduced central volume and cyclic variation of intrathoracic pressure on the variables frequently used to describe the HRV.
Objective: To prove that initiation of chronic ventilatory support at home, in patients with chronic hypercapnic respiratory failure due to neuromuscular disease (NMD) or thoracic cage problem is not inferior compared to initiation in a hospital based setting. In addition we believe that the start at home is cheaper compared to an in-hospital start. Hypothesis: Initiation of chronic ventilatory support at home is effective, safe and cost effective compared to a hospital-based initiation. Study design: A nationwide non-inferiority multi-center randomized parallel active control study. Study population: Patients with chronic respiratory insufficiency due to a neuromuscular disease (NMD) or thoracic cage problem who are referred for chronic ventilator support. Intervention: The start of HMV at home Standard intervention to be compared to: The start of HMV is normally in a clinical setting as recommended in the national guideline. Outcome measures: Primary: PaCO2. Secondary: Health related quality of life; lung function; nocturnal transcutaneous carbon dioxide assessment and saturation, and costs Sample size calculation/data analysis: This is a non-inferiority trial based on PaCO2 as primary outcome. A difference in favor of the hospital care group of smaller than 0.5 kPa will be labeled as non-inferior. To retain 72 evaluable patients, and allow for drop-outs, we will include 96 patients in total. Cost-effectiveness analysis: A cost analysis will be conducted alongside the clinical trial. Costs of the initiation of HMV at home and in the hospital will be estimated form a societal perspective over a time horizon of 6 months. Time schedule: After an initial phase of 6 months recruitment will start and will take 24 months. Thirty-six months after the start of the study the last assessments will be done and analysis and writing of the papers will start. After 42 months the study will end.
This study is designed to evaluate the occurrence of gastric insufflation and the critical volume of the stomach after three different modes of positive pressure ventilation during induction (Manual-controlled, volume-controlled and pressure-controlled ventilation)
Protective ventilation - combining a low tidal volume (between 6 and 8 ml/kg) and alveolar recruitment (AR) manoeuvres repeated every 30 minutes - is currently the standard of care for decreasing morbidity associated with mechanical ventilation. In contrast, there is no consensus on the type of recruitment manoeuvre, which varies from one centre to another and from one study to another. The investigators intend to compare two currently used AR techniques with regard to their ventilatory efficacy and hemodynamic safety: - An end-tidal plateau at 30 cmH20 for 30 seconds. - An end-tidal plateau at 10 cmH20 above the patient's plateau pressure for 30 seconds, without exceeding 30 cmH20.
