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.
2014年8月12日 · 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.
Mechanical Ventilation: Humidification (Respiratory Therapy)
In severe cases, thick airway secretions may occlude the artificial airway or obstruct the lower airways. Two types of humidification systems are available for use with mechanical ventilation: (1) active heated humidifier (HH) and (2) passive HME.
Humidity and Bland Aerosol Therapy: An Overview (2025)
2024年12月12日 · Summary: Bland aerosol therapy is a specialized form of humidification therapy targeted at enhancing airway clearance and improving respiratory function. It is widely used in both acute and chronic care settings , but it requires careful administration and monitoring to maximize benefits and minimize potential risks.
Humidification of the Airways Adequate for Function and Integrity ...
Subsequent rehumidification of the airway rapidly restored tracheal mucus velocity, but histologic evidence demonstrated that extensive inflammation and sloughing of ciliated epithelium in the trachea and bronchi were present despite the functional restoration observed.
Heating and humidification in the normal respiratory tract
2015年8月6日 · The upper airway is structurally designed to humidify the respiratory gas mixture by increasing the turbulence of inspired gas. The mucosa and the air exchange heat and moisture with each other, such that the air at the level just below the carina becomes 100% humidified and heated to body temperature.
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 …
Upper Airway Humidification: Physiology and Clinical Implications
2023年8月26日 · 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.
Physiological Effects of Humidification | RT - Respiratory Therapy
2016年4月4日 · Mechanically ventilated patients who do not receive some type of humidification may experience thickening of secretions, changes in the lung lining and obstruction of the airway, according to Madhu Sasidhar, MD, section head for respiratory care at the Cleveland Clinic.
Humidification in anaesthesia and critical care | BJA Education ...
2014年6月5日 · 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.
