Humidification and suctioning are necessary to manage secretions in patients on mechanical ventilation. According to Branson (2007), the optimal humidification level "has been not well defined, but it is clear that in a patient with thick and copious secretions a heated humidifier is preferred to an HME".

Respiratory gas humidification is a method of artificially conditioning respiratory gas for the patient during therapy, and involves humidification, warming, and occasionally filtration of the gas being delivered. If these three measures are not performed to compensate for the natural conditioning of air by the respiratory system, lung ...
Mapleson D systems are inefficient for spontaneous ventilation due to needing high gas flows to prevent rebreathing, but are efficient for controlled ventilation. A Bain system is a coaxial modification of the Mapleson D system. Mapleson E systems, also known as Ayre's T-piece, are used in anaesthesia for children. The reservoir consists of a ...
The development of heated humidified high flow started in 1999 with Vapotherm introducing the concept of high flow use with race horses. [2]High flow was approved by the U.S. Food and Drug Administration in the early 2000s and used as an alternative to positive airway pressure for treatment of apnea of prematurity in neonates. [3]
Ventilators may also be equipped with monitoring and alarm systems for patient-related parameters (e.g., pressure, volume, and flow) and ventilator function (e.g., air leakage, power failure, mechanical failure), backup batteries, oxygen tanks, and remote control. The pneumatic system is nowadays often replaced by a computer-controlled turbopump.
Bubble CPAP is a non-invasive ventilation strategy for newborns with infant respiratory distress syndrome (IRDS). It is one of the methods by which continuous positive airway pressure (CPAP) is delivered to a spontaneously breathing newborn to maintain lung volumes during expiration.
A lawyer for Shawn "Jay-Z" Carter is fighting back against the sexual assault allegations he's facing in a new lawsuit.
An adjustable pressure-limiting valve (commonly abbreviated to APL valve, and also referred to as an expiratory valve, relief valve or spill valve) is a type of flow control valve used in anaesthesiology as part of a breathing system. It allows excess fresh gas flow and exhaled gases to leave the system while preventing ambient air from ...
