What is Mechanical Ventilation?
Mechanical ventilation is a anatomy of handling used to help the patient in breathing or in reality will breathe for the affected role if he / she is unable to do so on their own.(1 , 2 , 3)A soul can be on a breathing equipment during surgical procedure or in cases where the lung are n’t functioning as they should.(1)The function of mechanical ventilation system is keeping the air lane opened , pass carbon dioxide and deliver oxygen to the body .
Mechanical ventilating system is not responsible for directly treating any diseases ; it is more of an aid or assist in stabilizing the patient while medications and other treatment serve in fighting the illness and assist the body to recover .
What is a Ventilator and What Are Its Functions?
It is a auto which help oneself the patient role in breathe similarly to how crutch help in supporting the weight . The ventilator completely or partially helps in tolerate the function of the lungs . The functions of the ventilator are:(4 )
Mechanical Ventilation vs. Intubation
Mechanical ventilation and intubation are commonly done together ; however , they both are dissimilar . canulization is where a tube is inserted down the throat into the trachea.(5)This tube then will be connected to a breathing machine . In some cases , the patient role is not intubated and instead a face mask is used to link the patient to the ventilator .
Different Types of Mechanical Ventilation
Noninvasive Ventilation:(6)In this character of respiration , a face mask is used instead of a tube to touch base the affected role to the ventilator . The masquerade is held firmly in place with the help of straps . The breathing apparatus prompt the zephyr into the lung . Other type of noninvasive ventilation system are devices which can be used at home , such as BiLevel positive airway press or CPAP .
Invasive Mechanical Ventilation:(6)In this case of ventilation system , there is a tube in the airway which is then connected to a breathing machine . This subway can go through the cervix ( tracheostomy ) or through the mouth ( cannulization ) .
When is Mechanical Ventilation Needed?
mechanically skillful breathing or public discussion is postulate during the play along scenarios :
What is the Duration Required By the Patient to Be Kept On Mechanical Ventilation?
The amount of time a patient needs mechanical ventilation count on the campaign of it and it can be hours to days to workweek and in some rare case even month or years . Most of the prison term , the patient role will require mechanically skillful ventilation for as little fourth dimension as possible . The MD will appraise the patient role ’s power to breathe without its support and decide the duration of mechanically skillful ventilation system and when to ablactate off .
In case the patient require to be on a ventilator for about a couple of weeks or more , then the doctor will likely change the affected role from an endotracheal tube to a tracheotomy where a tube is inserted via the neck into the airway
What is the Procedure of Invasive Mechanical Ventilation?
The procedure of invasive mechanical ventilation is as follows:(7 )
The patient role is give medicament for drugging so the patient can unlax and not move unnecessarily or fidget . An endotracheal thermionic vacuum tube is enter down the pharynx and trachea , which is the respiratory tract leading to the lung . The tube is then attach to the breathing equipment , which will serve in breathing . This patient will be kept on the breathing apparatus until the medical squad deems it dependable for the patient to emit on their own again .
All these step can alter look on patient to patient and their specific condition .
What Other Things Are Done When The Patient Is On A Ventilator?
When the affected role is on the breathing gadget , the doctor will do other necessary subprogram for preventing and treating tortuousness . These can consist of : monitoring , pass medications , suctioning , bronchoscopy , militarization , giving fluid and nutrition .
Other machine : extra machines can be connected to the patient to assess how the body is work . This can comprise of : heart rate , blood pressure , O levels and respiratory rate .
Suctioning is done to keep the airways clear and this is an important step . This is done by inserting a catheter into the breathing subway system , which will then remove mucus .
Investigations : stock tests and thorax X - ray can be done to look at the lung and find out the oxygen and carbon copy dioxide levels in the blood .
medicinal drug in aerosolized from are given via breathing tube . These medication roleplay better when they are inhaled directly into the lungs or airways . Intravenous medicine may also be throw as needed . Nutrition in smooth form is given when the patient role is on ventilator as patient can not run through anything when cannulize . The fluid solid food is given via the tube which is then passed through the nose and into the stomach . endovenous fluid are also given to the patient .
Mobilization means where the affected role is made to sit up on a regular basis and in some casing is also encouraged to get up and walk .
Bronchoscopy is done to curb the airways in the lungs . This is done by inserting a small , light up camera via the ventilation tube and into lungs . Samples of tissue or mucus can also be taken for examination .
Who Takes Care Of The Patient On A Ventilator?
The patient is kept on ventilator in an intensive tutelage unit ( ICU ) and is closely monitored by the doctors and other staff who are especially trained for caring the patients requiring mechanical ventilation .
Is the Patient Conscious When On A Ventilator?
When the patient is on a ventilator , the Dr. will endeavor to keep the patient awake as much as possible , while making certain that he / she is easy and relaxed .
Medications are throw for this purpose as ask . The patient role can be awake , but can also palpate confused , sleepy or not wholly comprehending of what is go on .
In some cases , depending on the patient role ’s illness , the doctor will keep the patient deep sedated so the patient is not disturbed and the body can reclaim . The arm of the patient might be restrained for forestall any ego - trauma , such as pulling on the metro when waking up .
How To Decide To Remove The Patient Off Mechanical Ventilation And What Happens After That?
The doctors will do tests to assess if the affected role can respire on their own and then resolve whether he / she can be take off the breathing gadget . The endotracheal tube is not move out when doing these trial run . As the term of the patient improves and the patient can breathe on their own , the Dr. will murder the endotracheal tube and then take the patient off mechanical ventilation .
There may be soreness of the throat or lip ; and gruffness of the vocalisation after removing the endotracheal underground .
The remotion of the ET tube is jazz as extubation after which the patient can be kept on other machine for assisting in breathing , such as O masks or noninvasive ventilating system using a mask . In some cases , depending on the status the patient can be intubated again and shifted back on mechanical respiration .
What Are The Benefits Of Mechanical Ventilation?
The advantages of mechanically skillful public discussion are :
What are the Risks of Mechanical Ventilation?
Despite all the concern taken to prevent or obviate complication there might be a few risk mechanical external respiration carries , such as:(8,9 )
Bacterial Infections : The bacteria can easily enter the lung via the ET tube and cause infections like VAP or breathing apparatus - associated pneumonia . antibiotic are used for treating this transmission .
Lung damagecan come about from the pressure exerted from the ventilator .
Collapsed lungcan also occur if an area of the lung is weakly , then it can develop a pickle , resulting in pneumothorax which is collapsing of the lungs .
variety in the pump and blood flow come about by being on a ventilator . If there are problems in the functioning of the heart , then there is decrease in the line pressure or increase in the heart rate . This result in reduced oxygen in the blood despite there being sufficient oxygen present in the lungs .
In casing where the affected role is unable to come up off the breathing apparatus or needs to be put on a ventilator for prolonged period of time , then the Dr. will remove the thermionic vacuum tube from the mouth and tuck in into the cervix via a small surgical incision .
Unnecessary suffering can go on as the mechanically skillful ventilation can extend the dying operation in case where the likeliness of the patient recovering from their precondition is nil . Keeping such patients on ventilators just foreclose destruction and cause lot of unneeded suffering . Ask your doc for counselling in hit these tough decision about mechanically skillful ventilation in such case .
What is the Outlook and Recovery Process from Mechanical Ventilation?
The amount of time need to get off the mechanically skillful ventilation system depends on the grounds of and the duration of which the affected role was on it . The doctor will manoeuvre the family members in terms of expectations and how to take care of the patient after being weaned off the mechanically skillful airing .
