Aug 12, 2014 · When the upper airway is bypassed during invasive me-chanical ventilation, humidification is necessary to prevent hypothermia, disruption of the airway epithelium, bron-chospasm, atelectasis, and airway obstruction. In severe.
Humidification during Mechanical Ventilation in the Adult Patient
In this review, we aim to describe the basic principles of airway humidification on mechanically ventilated patients, the most commonly used humidifier devices, and the proper selection of humidifiers according to the clinical condition.
Impact of Airway Humidification Strategy in Mechanically …
The choice of the humidification device used in subjects with COVID-19 had a relevant impact on ventilation efficiency (increased CO 2 removal with lower dead space) and on complications related to low humidity, including ETOs that may be …
Humidification of indoor air for preventing or reducing dryness ...
The question of whether humidification of indoor air prevents or alleviates dryness symptoms of the skin and mucosal membranes and reduces upper respiratory tract infections in workplaces and in kindergarten or at schools is important from a …
Humidification in anaesthesia and critical care | BJA Education ...
Jun 5, 2014 · Within the airways, humidification is achieved by evaporation of water from the airway surface liquid contained within the mucus, present on all respiratory surfaces. Respiratory mucus consists of two interacting layers: a luminal gel layer containing mucin and a deeper aqueous sol layer, which is produced by serous cells.
Humidification and heating of inhaled gas in patients with …
Instrumentation of the airways in critical patients (endotracheal tube or tracheostomy cannula) prevents them from performing their function of humidify and heating the inhaled gas. In addition, the administration of cold and dry medical gases and ...
Upper Airway Humidification: Physiology and Clinical Implications
Aug 26, 2023 · In this chapter, we will review the concept of humidity, the process of the upper airway humidification, and the implications of insufficient and excessive humidification, with biological and artificial ventilation.
Impact of Airway Humidification Strategy in Mechanically …
Feb 1, 2022 · Proper humidification of gas delivered to patients during mechanical ventilation is mandatory. Heat and moisture exchangers (HMEs) or heated humidifiers (HHs) may be used, with different performances in humidification and different …
Humidification, Airway Secretion Management, and Aerosol …
Apr 1, 2023 · Humidification increases the chances of success in applying NIV as it is related to managing respiratory secretions and increasing the feeling of well-being. Interface selection is a significant determinant of NIV success or failure, and the …
Heating and humidification in the normal respiratory tract
Aug 6, 2015 · The change in temperature and humidity occurs during respiration due to the effects of the upper airway structures on the inspired air mixture. Inspired gas passes through the convoluted air passages of the nasopharynx and pharynx which generates turbulence.
