Comparison of sterile inhalation water in oxygen humidifier bottles with tap water and investigation of antibacterial effects and endotoxin limits

In hospitals, medical air feeders and oxygen are used to create dry gas. Patients who need oxygen may experience upper respiratory tract problems due to inhalation of dry oxygen. Therefore, the airway must be humidified while the patient is receiving oxygen. This humidification process is carried out using sterilized water. Oxygen flowmeter is an instrument used in hospitals to adjust the level of oxygen gases. Sterile inhalation waters connected to these flowmeters are used in inpatient wards, intensive care units, operating rooms and all areas where oxygen needs to be administered to the patient. In this study, parameters that will affect water quality such as endotoxin limits, antimicrobial effects and heavy metals contained in untreated, non-sterile tap water and disposable sterile inhalation waters were compared with international norms such as ISO 22519 Standard and European Pharmacopoeia. As a result of the analyzes, it has been proven that the waters contained in the sterile inhalation system produced by Estaş comply with international norms. In addition, it is foreseen that if sterile water cannot be used in hospitals, antibacterial, antiviral, antimicrobial negative effects will occur or if the same water is used more than once, cross-contamination will occur and different indications will occur. The use of sterile inhalation waters in accordance with the instructions for use reduces the risk of possible infection and ensures that the patient's saturation value reaches the desired level and provides ease of breathing. This solution aims to improve patient care conditions by reducing the risk of infection.
