Study Notes
Humidification in Respiratory Care
- Humidification aims to maintain a healthy, moist environment within the lower airways.
- Adequate humidity supports the proper functioning of the mucociliary transport system, responsible for clearing debris from the lungs.
- Humidification therapy is also used to address various respiratory conditions.
- Dry medical gases delivered at high flow rates (greater than 4 L/min) can cause significant heat and water loss in the upper airways, leading to epithelial damage if prolonged.
- Exposure to cold, dry air impairs ciliary motility, increases airway irritation, elevates mucus production, and thickens pulmonary secretions due to dehydration.
- The risks associated with breathing dry gas are amplified when the body's natural heat and water exchange mechanisms are compromised.
