Controlled ventilation with a Mapleson A (Magill) breathing system: reassessment using a lung model.
We have used a lung model to reassess the efficiency of the Magill attachment during controlled ventilation in which the pattern of ventilation, tidal volume and fresh gas flows were varied. Adjustment of the inspiratory:expiratory ratio to ensure a prolonged expiratory phase is recommended, to improve efficiency and predictability of the system, if its use is necessary for short periods during...
متن کاملA theoretical study of gaseous homeostasis in the Magill circuit.
Equations have been derived to determine the alveolar gas concentrations which occur when the Magill (Mapleson A) circuit is used with a low fresh gas flow. Alveolar oxygen and carbon dioxide concentrations are determined by the fresh gas flow and composition, carbon dioxide output and oxygen uptake. Gas mixing within the circuit and alterations in the inspired gas concentrations do not affect ...
متن کاملVolume-guaranteed Ventilation Versus Pressure-controlled Ventilation in Preterm Infants with Respiratory Distress Syndrome: A Randomized Controlled Trial
Background: This study was targeted toward comparing volume-guaranteed (VG) ventilation with conventional pressure-controlled (PC) ventilation in preterm infants with respiratory distress syndrome (RDS) in terms of the facilitation of weaning and extubation and occurrence of complications, such as pneumothorax, intraventricular hemorrhage (IVH), retinopathy of prematur...
متن کاملRemembering Alan Magill
We note with profound sadness the unexpected death of Alan J. Magill, MD, FASTMH, immediate past-president of the American Society of Tropical Medicine and Hygiene (ASTMH), on September 19, 2015 outside Seattle. Alan was president of our Society in 2014. He served with distinction, bringing to this elected position his characteristic enthusiasm, optimism, and focus. A noteworthy feature of his ...
متن کاملAnaesthetic breathing systems in the accident and emergency department.
We report two cases where patients with an acute head injury developed hypercapnia as a result of the inappropriate use of the Magill breathing circuit. The Magill circuit is inefficient when used for controlled ventilation because the patient is ventilated with his own expired gas and develops hypercapnia. The suitability of alternative breathing systems are discussed.
