Varying leaks: a challenge for modern ventilators?
Using patient-triggered ventilation, during which the patient is given the opportunity to trigger and cycle the ventilator, allows reducing the use of sedation,1 reduces ventilator-induced diaphragmatic dysfunction,2 facilitates weaning from mechanical ventilation,3 and improves patient comfort.4 To be efficient and comfortable, patient-triggered modes have to deliver pressurization in synchron...
متن کاملModern Anesthesia Ventilators and the Pediatric Patient
Mechanical ventilation of pediatric patients in the operating room can be challenging. Even small changes in delivered volume can be a significant percentage of the desired volume and lead to unintended hyperor hypoventilation. Due to the unique physiology of children,the consequences of these unintended ventilation changes can be hypoxemia, hypercarbia and/or barotrauma. When using a tradition...
متن کاملEffect of dynamic random leaks on the monitoring accuracy of home mechanical ventilators: a bench study
BACKGROUND So far, the accuracy of tidal volume (VT) and leak measures provided by the built-in software of commercial home ventilators has only been tested using bench linear models with fixed calibrated and continuous leaks. The objective was to assess the reliability of the estimation of tidal volume (VT) and unintentional leaks in a single tubing bench model which introduces random dynamic ...
متن کاملSeven Ventilators Challenged With Leaks During Neonatal Nasal CPAP: An Experimental Pilot Study.
BACKGROUND Nasal CPAP is the most common respiratory support for neonates. Several factors are considered important for effective treatment, including leaks at the patient interface and the delivery of pressure-stable CPAP. Investigations of pressure stability during leaks should include both the change in the mean delivered CPAP and the pressure variation during each breath. The aim of this st...
متن کاملPerformance of ICU ventilators during noninvasive ventilation with large leaks in a total face mask: a bench study* **
OBJECTIVE Discomfort and noncompliance with noninvasive ventilation (NIV) interfaces are obstacles to NIV success. Total face masks (TFMs) are considered to be a very comfortable NIV interface. However, due to their large internal volume and consequent increased CO2 rebreathing, their orifices allow proximal leaks to enhance CO2 elimination. The ventilators used in the ICU might not adequately ...
