Common risks include:. The medical team will assess and be aware of these potential risks, and do what they can to address them. Prior to intubation, the patient is typically sedated or not conscious due to illness or injury, which allows the mouth and airway to relax.

The patient is typically flat on their back and the person inserting the tube is standing at the head of the bed, looking at the patient's feet. The patient's mouth is gently opened and using a lighted instrument to keep the tongue out of the way and to light the throat, the tube is gently guided into the throat and advanced into the airway. There is a small balloon around the tube that is inflated to hold the tube in place and to keep air from escaping.

Once this balloon is inflated, the tube is securely positioned in the airway and it is tied or taped in place at the mouth. Successful placement is checked first by listening to the lungs with a stethoscope and often verified with a chest X-ray. In the field or the operating room, a device that measures carbon dioxide—which would only be present if the tube was in the lungs, rather than in the esophagus—is used to confirm that it was placed correctly. In some cases, if the mouth or throat is being operated upon or has been injured, the breathing tube is threaded through the nose instead of the mouth, which is called nasal intubation.

The nasotracheal tube NT goes into the nose, down the back of the throat, and into the upper airway. This is done to keep the mouth empty and allow the surgery to be performed. This type of intubation is less common, as it is typically easier to intubate using the larger mouth opening, and because it just isn't necessary for most. The process of intubation is the same with adults and children, aside from the size of the equipment that is used during the process.

A small child requires a much smaller tube than an adult, and placing the tube may require a higher degree of precision because the airway is so much smaller. In some cases, a fiberoptic scope, a tool that allows the person putting the breathing tube in to watch the process on a monitor, is used to make intubation easier. The actual process of placing the tube is essentially the same for adults as it is for older children, but for neonates and infants, nasal intubation is preferred.

While an adult may have questions about insurance coverage, risks, benefits, and recovery times, a child will require a different explanation of the process that is going to occur. Reassurance is necessary, and emotional preparation for surgery will vary depending on the patient's age.

A patient who will be on the ventilator for a procedure and then extubated when the procedure is completed will not require feeding but may receive fluids through an IV. If a patient is expected to be ventilator-dependent for two or more days, feeding will typically be started a day or two after intubation.

It isn't possible to take food or fluids by mouth while intubated, at least not the way it's typically done by taking a bite, chewing, then swallowing. To make it possible to safely take food, medication, and fluids by mouth, a tube is inserted into the throat and down into the stomach. This tube is called an orogastric OG when it is inserted into the mouth, or a nasogastric tube NG when inserted into the nose and down into the throat.

Medication, fluids, and tube feeding are then pushed through the tube and into the stomach using a large syringe or a pump. For other patients, food, fluids, and medications must be given intravenously. IV feedings, called TPA or total parenteral nutrition, provides nutrition and calories directly into the bloodstream in liquid form. This type of feeding is typically avoided unless absolutely necessary, as food is best absorbed through the intestines.

The tube is far easier to remove than to place. When it is time for the tube to be removed. Then the balloon that holds the tube in the airway is deflated so that the tube can be gently pulled out. And that could be a long time. King says, while a ventilator might save your life, it is certainly not a pleasant experience. And while a young and healthy person with COVID might not need a ventilator, there are others who will.

It sends oxygen or air into the lungs through a thin tube and allows carbon dioxide to escape. The tube is placed in the windpipe through the nose or mouth. If the person needs the ventilator for a long period of time, the surgeon may place the tube in an opening made directly into the windpipe through the neck.

This is called a tracheostomy, or "trach" say "trayk" tube. The tube is placed in the opening. A continuous positive airway pressure CPAP machine may be used when a ventilator isn't needed. It gently pushes oxygen or air into the lungs through a mask over the nose or mouth. People can breathe on their own with this extra help. A nasal cannula is a device with two prongs that are placed in the nostrils when a person just needs more oxygen.

The oxygen goes through the tubes and into the nostrils. Oxygen may also be given through a mask. Oxygen flows through a tube and into a mask that is placed over the nose and mouth.

A heart monitor has a sensor that attaches to the chest to track heart rate. A pulse oximeter clips to the end of the finger.
