View clinical trials related to Tidal Volume.
Filter by:Acute respiratory distress syndrome (ARDS) is a heterogeneous syndrome with similar clinicopathological feathers caused by different etiologies. Respiratory supportive strategies is the main ARDS management, and the guidelines recommend low tidal volume to improve clinical outcomes. To be note, overdistension can still occur even if using a tidal volume as low as 6 ml/kg, given the heterogeneous nature of the syndrome. Therefore, adjusting tidal volume level to less than 6ml/kg may reduce ventilator-induced lung injury (VILI) and thus improve outcomes, especially in patients with severe lung injury. Prone position is also an important management in severe ARDS. Prone position can improve ventilation-perfusion (V/Q) matching and reduce the risk of VILI by recruiting dorsal collapsed alveoli. Meanwhile, prone position has also been shown to improve hemodynamics. Recent studies have showed that prone position did not reduce duration of venovenous extracorporeal membrane oxygenation (VV-ECMO) and 90-day mortality in patients with ARDS who receive VV-ECMO with ultra-low tidal volume ventilation. Therefore, the effect of PP on ventilation and lung blood flow in ARDS patients treated with VV-ECMO wiht ultra-low tidal volume ventilation remains unclear.
The goal of this observational study is collect data to evaluate the efficacy of the RMS system in monitoring, recording, and presenting respiratory function data to the user in participants scheduled for pulmonary function testing (PFT). Participants will complete: - 60 episodes of data collection with a decreased tidal volume - 30 episodes of data collection with an increased tidal volume - 80 episodes with normal tidal volume breathing The TSS will continuously transmit sound data to an adjacent personal computer (PC) via Bluetooth Low-Energy (BLE). TSS trachea sound data will be recorded on the PC and then transmitted via a secure wireless network to an RTM cloud account that is HIPPA compliant. Reference breathing data will be simultaneously recorded using an FDA approved hospital ventilator (Hamilton Medical, HAMILTON-C1) with a calibrated pneumotach, capnometer, and a tight-fitting face mask. This system accurately measures and records a spontaneously breathing patient's RR, TV, MV, and end-tidal carbon dioxide concentration.
Some ICU ventilated patients might present with large tidal volume despite very low or inexistant presser support. Patient-Self Inflicted Lung Injury (P-SILI) might appear related with large alveolar stretch an distension. Two clinical presentations are observed: patients with or without respiratory distress signs such as supra-clavicular depression and thoracic-abdominal asynchronies. The aim of this study is to compare the pulmonary physio(-patho)logical parameters of these two types of patients (eupneic or with respiratory distress signs), and presenting important TV in spite of a minimal adjustment of the ventilatory support, except for Acute Respiratory Distress Syndrome (ARDS).
The aim of the study is to evaluate the ability of ulna length to predict accurate protective lung tidal volume in Egyptian people in reference to their standing height.
This study is aimed at evaluating patient work of breathing and tidal volumes with three methods of oxygenation: standard oxygen, high-flow oxygen therapy and non-invasive ventilation.
