Effect of Position and Pneumoperitoneum on Respiratory Mechanics and Transpulmonary Pressure During Laparoscopic Surgery

This study is an observational study measuring the esophageal pressure in anesthetized surgical patient undergoing changes in posture and pneumoperitoneum

Assessment of Esophageal Pressure Reliability to Estimate Pleural Pressure in Critically Ill Children

Background During ventilatory assistance, optimization of settings is critical to allow a personalized support and avoid over- or under-assistance. But little data are available in clinica...

Spirometry in Esophageal Intubation

The primary objective of the study is to describe the pressure patterns during esophageal and tracheal ventilation and to validate the diagnostic algorithm.

Study of Variations of Pleural and Esophageal Pressures Under Mechanical Ventilation After Lung Transplantation

The primary objective of the study is to determine the correlation between mean pleural pressure and oesophageal pressure in the immediate aftermath of bi-pulmonary transplantation. ...

ARDS Esophageal Balloon Pressure Changes With Positioning Study

The use of esophageal balloon catheters, which use esophageal pressure as a surrogate measurement for transpleural pressure, shows promise in improving outcomes of patients with severe acu...

Impact of large volume paracentesis on respiratory parameters including transpulmonary pressure and on transpulmonary thermodilution derived hemodynamics: A prospective study.

Appropriate mechanical ventilation and prevention of alveolar collaps is mainly dependent on transpulmonary pressure TPP. TPP is assessed by measurement of esophageal pressure EP, largely influenced b...

The effects of one-lung ventilation mode on lung function in elderly patients undergoing esophageal cancer surgery.

The objective of the present study was to explore the effects of different one-lung ventilation (OLV) modes on lung function in elderly patients undergoing esophageal cancer surgery. A total of 180 co...

Nasal High-Frequency Oscillatory Ventilation Inhibits Gastroesophageal Reflux in the Neonatal Period.

Nasal high-frequency oscillatory ventilation (nHFOV) in neonates is increasingly considered due to enhanced alveolar ventilation, absence of patient-ventilator asynchrony and lessened ventilator-induc...

Esophageal pressure monitoring: why, when and how?

Esophageal manometry has shown its usefulness to estimate transpulmonary pressure, that is lung stress, and the intensity of spontaneous effort in patients with acute respiratory distress syndrome. Ho...

Biphasic Cuirass Ventilation During Anesthesia for Tracheobronchial Stent Insertion or Removal by a Rigid Bronchoscope: A Case Report.

Airway management and ventilation during a tracheobronchial stenting procedure are challenging given that mandatory positive pressure ventilation cannot be fully achieved while using a rigid bronchosc...

Medical and Biotech [MESH] Definitions

Techniques for effecting the transition of the respiratory-failure patient from mechanical ventilation to spontaneous ventilation, while meeting the criteria that tidal volume be above a given threshold (greater than 5 ml/kg), respiratory frequency be below a given count (less than 30 breaths/min), and oxygen partial pressure be above a given threshold (PaO2 greater than 50mm Hg). Weaning studies focus on finding methods to monitor and predict the outcome of mechanical ventilator weaning as well as finding ventilatory support techniques which will facilitate successful weaning. Present methods include intermittent mandatory ventilation, intermittent positive pressure ventilation, and mandatory minute volume ventilation.

Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.

Ventilatory support system using frequencies from 60-900 cycles/min or more. Three types of systems have been distinguished on the basis of rates, volumes, and the system used. They are high frequency positive-pressure ventilation (HFPPV); HIGH-FREQUENCY JET VENTILATION; (HFJV); and high-frequency oscillation (HFO).

Endoscopic surgical procedures performed with visualization via video transmission. When real-time video is combined interactively with prior CT scans or MRI images, this is called image-guided surgery (see SURGERY, COMPUTER-ASSISTED).

Disorders affecting the motor function of the UPPER ESOPHAGEAL SPHINCTER; LOWER ESOPHAGEAL SPHINCTER; the ESOPHAGUS body, or a combination of these parts. The failure of the sphincters to maintain a tonic pressure may result in gastric reflux of food and acid into the esophagus (GASTROESOPHAGEAL REFLUX). Other disorders include hypermotility (spastic disorders) and markedly increased amplitude in contraction (nutcracker esophagus).
