Breathing circuits are medical devices used to deliver oxygen and other gases to patients who are unable to breathe on their own. They are commonly used in hospitals and other healthcare settings to treat patients with a variety of conditions, including pneumonia, asthma, and chronic obstructive pulmonary disease (COPD).<br /><br /><br /><br />How Breathing Circuits Work<br />Breathing circuits are made up of several components, all together form respiratory support these components are.<br /> A. A ventilator: This is a machine that delivers oxygen and other gases to the patient.<br /> B. Breathing tubes: These tubes connect the ventilator to the patient's airway.<br /> C. A humidifier: This device adds moisture to the gases delivered by the ventilator, which helps to keep the patient's airways moist and prevents them from drying out.<br /> D. Unidirectional valves: These valves prevent exhaled gases from being inhaled again by the patient.<br /> E. Water traps: These devices collect any water that condenses in the breathing circuit, which helps to prevent it from reaching the patient's lungs.<br /><br />Types of Breathing Circuits<br />There are two main types of breathing circuits:<br /> A. Bain circuit: This is the most common type of breathing circuit. It is a simple, lightweight circuit that is easy to use.<br /> B. Mapleson circuit: This type of circuit is more complex than the Bain circuit. It is used for patients who require more advanced ventilation support.<br />Benefits of Using a Breathing Circuit<br />Breathing circuits offer a number of benefits for patients who are unable to breathe on their own. These benefits include:<br /> • Improved oxygenation: Breathing circuits deliver oxygen directly to the patient's lungs, which helps to improve their blood oxygen levels.<br /> • Reduced work of breathing: Breathing circuits can help to reduce the effort that the patient has to exert to breathe.<br /> • Reduced risk of infection: Breathing circuits can help to reduce the risk of infection by preventing exhaled gases from being inhaled again by the patient.<br /> • Improved comfort: Breathing circuits can help to improve the patient's comfort by providing them with a steady supply of oxygen and other gases.<br />Conclusion<br />Breathing circuits are essential medical devices that help to keep patients who are unable to breath on their own. It considers a connection between patient lungs and the ventilator wither its mechanical or supportive technique, they are a safe and effective way to deliver oxygen and other gases to the lungs, and they can help to improve the patient's overall health and well-being.<br /><br /><br /> <br />م م نهى نوماس شاطي <br />Al-Mustaqbal University is the first university in Iraq
