摘要

1. Patient related indications for ventilatory support include inadequate alveolar ventilation, excessive work of breathing and/or hypoxemia. Thoracic surgery and the use of muscle paralytics necessitate the use of ventilatory support while patients undergoing laparoscopic procedures generally benefit from ventilatory support.2. Ventilatory support during general anesthesia can improve alveolar ventilation and oxygenation in addition to reducing a patient's work of breathing and ensuring adequate delivery of inhalant anesthetics.3. Mechanical ventilators used in conjunction with anesthetic agent delivery systems are classified as volume and/or pressure limited. Continuous positive pressure ventilation is the most frequently applied mode of ventilatory support during general anesthesia.4. The goal of ventilatory support is to achieve arterial carbon dioxide and oxygen levels of 35-45 mmHg and greater than 100 mmHg respectively. To achieve these targets the tidal volume is generally set to deliver 10-12 ml/kg at a frequency of 10-12 breaths per minute.
