OMAHA, Neb. - March 5, 2019 - PRLog -- What Is Respiratory Intubation?

Respiratory intubation is a procedure used by doctors to help a person breathe. It involves inserting a tube through the mouth or nose and into the windpipe, or trachea. The tube assists the person in breathing by using a ventilator.

The doctor stands near the head of the patient and inserts the tube, most commonly through the mouth. The tube has an inflated balloon-like portion at the end which keeps it stable after placement. In some cases, the tube is inserted via the nose through the nasal method instead of the mouth. For instance, if the mouth or the neck is being operated then respiratory intubation may be performed via the nose.

What Are the Risks Involved?

Respiratory intubation is a very simple procedure but there are some potential dangers which might complicate the process. These potential risks include:

·         Inserting the tube in the food pipe (esophagus) instead of the windpipe (trachea)

·         Damaging the insides of the mouth and the windpipe

·         Bleeding

·         Saliva or other liquids entering the windpipe

·         Risk of aspiration pneumonia in the case of fluid entering the windpipe and eventually the lungs

Why Is Respiratory Intubation Needed?

Respiratory intubation is needed for patients who cannot breathe themselves. Patients who are administered anesthesia are usually intubated because anesthesia makes their muscles relax and their lung muscles do not expand while breathing. Through respiratory intubation and mechanical ventilation, these patients are able to breathe normally while under the affects of anesthesia.

Other medical conditions such as respiratory problems and pneumonia also make it difficult for patients to breathe on their own. This necessitates respiratory intubation.

How Does Mechanical Ventilation Work?

Mechanical ventilation is the process of supplying air into the lungs through a narrow tube. The air is supplied through a special breathing machine known as a ventilator. The machine is set at a specific pressure at which air is blown into the lungs so that the person can breathe easily. It can be set to blow air a certain number of times per minute, a preset volume of air, and other parameters such as the percentage of oxygen in the air can be precisely controlled. The doctor sets it according to the patient's requirement.

When Is the Ventilator Switched Off?

The duration for which the patient must be kept on the ventilator is decided by measuring some parameters and observing the patient's condition. If the patient has been intubated because of a surgical procedure, then the ventilator is weaned off as soon as the surgery is done. Otherwise, the following parameters are considered before weaning from mechanical ventilation:

·         The patient's breathing rate

·         The volume of air displaced in the lungs

·         The maximum volume of air that can be inhaled and exhaled

·         The volume of air inhaled and exhaled in a minute

The patient is checked for the above-mentioned parameters and if they are normal, the patient can be weaned from the ventilator.

If you or any of your loved one are about to undergo this process, don't worry. The doctor will discuss the potential risks and dangers with the patient before putting them on the ventilator. This is a very common process so you don't need to worry about it.
