How Do HME Filters Word.docx

1. How Do HME Filters Work? When the air we breathe is not hot and humid, it can cause thick, dry and bloody saliva, which can block the airways, making mechanical breathing susceptible to infections and respiratory difficulties. Humid, and warm heat and Heat Moisture Exchange Filter (HMEF) allow air to enter the lungs when one's normal breathing is disturbed. They maintain a proper airway temperature to avoid dryness, bacterial accumulation, infections and troubles. HME filters are also not used to prevent any potential tube attachment. Where are the HME filters placed? In medical care heat and moisture exchange filters are placed between the respiratory circuit to heat and supply moisture to the upper respiratory tract to patients under mechanical ventilation or under anaesthesia and hence the Y-piece (between the respiratory system and the patient). Why are HME filters so important and necessary? The upper respiratory airways (nose and mouth) naturally moisturize the air we breathe. Once you breathe in, this airway becomes moist and filtered before air reaches the lungs. When air is not inhaled through our nose or mouth, it does not heat up naturally or is humid. HME filters are important and necessary because they help patients who are not ready to breathe through the upper airways. HME Filters Help: Prevent and stop the spread of bacteria and microbes in the airways Moisturizing and moisturizing The patient's exhaled gases are used to heat and moisten the air that is inhaled. Prevent respiratory disorders Ensure much better recovery and reduce the risk of respiratory problems. Reduces ventilation disturbances Avoids cross contamination on patient and device

2. Reduces the risks of cannula and tube displacement. Respiratory pressure decreases HMEF benefits: Allows universal connectors to be connected Can be used safely and effectively for quite 3 days Light and convenient and really easy to use Help prevent respiratory complications Provides protection of patient and devices from possible particles in the system Allows visual control of device and airway mechanism Where and when should HME filters be used? In OR, when patients are under anaesthesia. Intensive care units, while using mechanical ventilation.
