How Endotracheal Tube is Used Endotracheal tube is a flexible tube made of plastic that is passed through the mouth and into the windpipe to aid in breathing. The tube is connected to a ventilator to deliver oxygen to the lungs. Endotracheal Intubation is the process of inserting a tube. Endotracheal tubes can be used for many reasons, such as surgery under general anesthesia, trauma or serious illness. Find out about the procedure, possible risks, complications, and what to expect. Scope When a patient cannot breathe, an endotracheal tube may be used to "rest" them or protect their airway. Uses There are many indications that an endotracheal tube should be placed. General Surgery: General anesthesia paralyzes the muscles, including the diaphragm, and allows the ventilator to breathe. Foreign body removal: An endotracheal tube or a Laryngeal Mask can be used to assist with the removal of foreign bodies that have been aspirated (breathed into) in the trachea.

Steps to Use Closed Suctioning Wash your hands in accordance with your unit protocol. Wash your hands according your unit protocol. We recommend using facial protection and gloves while working with the device. Your unit protocol may require you to take additional protective measures. How to determine the right catheter size and configuration.. Disconnect the device from the packaging and connect the flexible tube. Attachment of the day-change sticker. Connect the wall suction line and set the vacuum level. With gloves on, insert device into ventilation circuit (humidified, or HME). Monitor the ventilator parameters and assess the patient's need for suctioning. To unlock the thumb valve, lift the cap and then press and hold the valve. To reach the desired pressure, completely depress the valve a nd adjust the manometer reading. Attach a saline vial to the irrigation port cap. You will need to stabilize the ET tube, manifold and ET tube using one hand. Reposition the suction tube. Monitor patient and check ventilator.
Your Weight on Other Worlds Ever wonder what you might weigh on Mars or The Moon? Here's your chance to find out. <div class="js-required"><hr> This Page requires a Javascript capable browser <hr></div> Fill in your weight below in the space indicated. You can enter your weight in any unit you wish. Click on the "Calculate" button. Mass and Weight Before we get into the subject of gravity and how it acts, it's important to understand the difference between weight and mass. We often use the terms "mass" and "weight" interchangeably in our daily speech, but to an astronomer or a physicist they are completely different things. Weight is an entirely different thing. If you are in a spaceship far between the stars and you put a scale underneath you, the scale would read zero. The Relationship Between Gravity and Mass and Distance As stated above, your weight is a measure of the pull of gravity between you and the body you are standing on. The two "M's" on top are your mass and the planet's mass. Isaac Newton
Physics - spotlighting exceptional research What is HME And Its Types When the structures of the upper airways are not being used during anaesthesia or intensive care, heat and moisture exchangers and breath system filters can be used to replace them. Their use is still being regulated. This review will describe their efficiency and principles and summarize the results of laboratory and clinical studies. According to previous research, the appropriate moisture output target is 30 and 20 grams per hour for short-duration anaesthesia and intensive care. Reusing a breathing system under anaesthesia is possible if it is protected by a filter. There is a wide range in gas-borne filter performance. contaminated condensate may pass through filters at typical pressures during mechanical ventilation. The normal warming, humidifying, and filtering functions of upper airways are lost when a patient's trachea or supraglottic device is placed in place. There are five types of devices available. Heat and moisture exchanger without filter (HME). Only electrostatic filter
Symphony of Science Normal Distribution Calculator The Normal Distribution Calculator makes it easy to compute cumulative probability, given a normal random variable; and vice versa. For help in using the calculator, read the Frequently-Asked Questions or review the Sample Problems. To learn more about the normal distribution, go to Stat Trek's tutorial on the normal distribution. Note: The normal distribution table, found in the appendix of most statistics texts, is based on the standard normal distribution, which has a mean of 0 and a standard deviation of 1. Instructions: To find the answer to a frequently-asked question, simply click on the question. Why is the normal distribution so important? The normal distribution is important because it describes the statistical behavior of many real-world events. Thus, given the mean and standard deviation, you can use the properties of the normal distribution to quickly compute the cumulative probability for any value. What is a standard normal distribution? z = (X - μ) / σ Normal equation.
Bag Valve Mask (BVM) - HSI Medical Bag-Valve-Mask (BVM) devices, also known as Ambu bags, are self-inflating manual resuscitation systems. In BVM ventilation, a self-inflating bag (resuscitator bag) is attached to a nonrebreathing valve and then to a face mask that conforms to the soft tissues of the face. The opposite end of the bag is attached to an oxygen source (100% oxygen) and usually a reservoir bag. The mask is manually held tightly against the face, and squeezing the bag ventilates the patient through the nose and mouth. Unless contraindicated, airway adjuncts such as nasopharyngeal and/or oropharyngeal airways are used during BVM ventilation to assist in creating a patent airway. HSI Medical’s BVMs are guaranteed to exceed your expectations, increase your bottom line (profit) and assist rescue workers do their jobs effortlessly. Product features:
