Effects of Increased Tidal Volume on Internal Jugular Vein Cross-sectional Area

2014-07-24 14:00:49 | BioPortfolio

Summary

As increasing tidal volume, the cross sectional area and circumference of Internal Jugular Vein (IJV) could increase. And In the previous study, Trendelenburg position can increase size of IJV. So investigators would compare the cross sectional area, circumference of IJV and peak airway pressure in neutral and Trendelenburg position

Physiological Effects of Lung Recruitment During General Anesthesia and Low-tidal Volume Ventilation

Low-tidal volume ventilation is arising as a tool to optimize the ventilatory management and to improve clinical outcome in patients undergoing general anesthesia for abdominal surgery. A...

Ability of Changes in End Tidal Carbon Dioxide to Assess the Stroke Volume Effects of a Volume Expansion of 250ml of Crystalloid in the Operating Room

Volume expansion is the cornerstone of perioperative hemodynamic optimization. The main objective of volume expansion is to increase and to maximize stroke volume. Despite national and int...

A Feasibility Study of a Low Tidal Volume Ventilation Strategy in One Lung Ventilation

A study of two ventilatory strategies for low tidal volume ventilation compared to a control group to elucidate if low tidal volumes of 3ml/kg or 4ml/kg were feasible for one lung ventilat...

Tidal Volume Challenge and Reliability of Plethysmography Variability Index

The aim of this study is to investigate whether a temporary increase in tidal volume can predict fluid responsiveness in patients receiving a low tidal volume ventilation in hepatic resect...

Variable Ventilation Associated With Recruitment Maneuver Minimizes Tissue Damage and Pulmonary Inflammation in Anesthetized Lung-Healthy Rats.

Recruitment maneuver and positive end-expiratory pressure (PEEP) can be used to counteract intraoperative anesthesia-induced atelectasis. Variable ventilation can stabilize lung mechanics by avoiding ...

Randomized Feasibility Trial of a Low Tidal Volume-Airway Pressure Release Ventilation Protocol Compared With Traditional Airway Pressure Release Ventilation and Volume Control Ventilation Protocols.

Low tidal volume (= tidal volume ≤ 6 mL/kg, predicted body weight) ventilation using volume control benefits patients with acute respiratory distress syndrome. Airway pressure release ventilation ...

Evaluating Delivery of Low Tidal Volume Ventilation in Six ICUs Using Electronic Health Record Data.

Mechanical ventilation with low tidal volumes is recommended for all patients with acute respiratory distress syndrome and may be beneficial to other intubated patients, yet consistent implementation ...

Readiness for Discharge After Foot and Ankle Surgery Using Peripheral Nerve Blocks: A Randomized Controlled Trial Comparing Spinal and General Anesthesia as Supplements to Nerve Blocks.

Neuraxial anesthesia is often viewed as superior to general anesthesia but may delay discharge. Comparisons do not typically use multimodal analgesics and nerve blockade. Combining nerve blockade with...

Ultra-Low Tidal Volume Ventilation - A Novel and Effective Ventilation Strategy During Experimental Cardiopulmonary Resuscitation.

The effects of different ventilation strategies during CPR on patient outcomes and lung physiology are still poorly understood. This study compares positive pressure ventilation (IPPV) to passive oxyg...

Medical and Biotech [MESH] Definitions

The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE VOLUME plus residual volume.

Abnormally slow pace of regaining CONSCIOUSNESS after general anesthesia (ANESTHESIA, GENERAL) usually given during surgical procedures. This condition is characterized by persistent somnolence.

The maximum volume of air that can be inspired after reaching the end of a normal, quiet expiration. It is the sum of the TIDAL VOLUME and the INSPIRATORY RESERVE VOLUME. Common abbreviation is IC.

The volume of air inspired or expired during each normal, quiet respiratory cycle. Common abbreviations are TV or V with subscript T.

The period of emergence from general anesthesia, where different elements of consciousness return at different rates.
