ventilator weaning protocol Let us know


ventilator weaning protocol، The breathing artificial is primarily to maintain the clear airway and stimulate inhalation and exhalation . Unlike cardiorespiratory resuscitation , this method does not involve chest compressions to revitalize blood circulation.

ventilator weaning protocol

The fundamental tactic is mouth-to-mouth breathing, in which the lifeguard exhales into the mouth of the unfortunate, allowing time for the victim to exhale in turn.

It is a combination of two resuscitation techniques that, in some cases, are used separately: mouth-to-mouth breathing and cardiac massage .


If after a serious accident the person does not breathe (for example, in a drowning or an electrocution), it is necessary to start artificial ventilation immediately, combining it with cardiac massage, if not, it has a pulse .


Basic resuscitation begins with the diagnosis of respiratory arrest. For this you must:

Check the loss of consciousness (lack of response to stimuli, flaccidity).
Artificial respiration
If despite having clear airways, the person can not breathe, do not let time pass for any reason. In any case, if the person was breathing, this measure would not cause damage.

The nose to mouth method is, in most cases, more hygienic than mouth to mouth.


The lifeguard must kneel on the side of the affected person’s head. Then you should stretch your head, stretch forward the lower jaw and close the affected person’s mouth. The thumb of the lower hand of the rescuer should be located between the lower lip and the tip of the bulb to close the patient’s mouth.
The lifeguard inspires in a normal way and puts his mouth in the nostrils of the affected person. The lips press the nose lightly.

Nose to mouth breathing

The lifeguard blows his air inside the nose. The lifeguard’s inspiration is achieved by turning the head towards the side so as not to breathe the exhaled air of the affected person.
With an ear near the nostrils examine the noise of exhalation.

Types of Methods

Immediate intervention of first aid that tends to recover a state of asphyxia that prevents breathing and places the individual in danger of death.

The methods are several.

Galliano method

With this system the maneuvers can be practiced by a single person.

The person is placed face up, the aspiration is provoked by raising the arms vertically, that is, elevating them until they are placed behind the nape of the neck . Then to cause expiration, the lifeguard will be placed in front of the patient, compressing the chest with the palms of the hands.

Compressing the thorax

For this method it is more advisable the presence of two lifeguards.

The person is placed face up, with the thorax slightly raised, which is obtained by putting behind the back a cushion or other similar object, the head should be tilted to the right. We must make sure that the tongue is not obstructing the larynx. The patient’s arms are taken, flexed at the elbow, and placed vertically on the thorax, then extended over the head. In this way the inspiration will be mechanically provoked. For expiration the patient’s arms are lowered over the chest, compressing the thorax and determining the exit of air. The number of respiratory movements should be more or less normal (15 – 18 per minute in adults, 20 – 24 in children).

Schaefer method

The patient placed face down on a mat, or similar object, with a cushion at the height of the epigastrium: the head will be rotated to the side. The lifeguard kneeling; between his legs, those of the patient; his hands will rest with his palms open on the last ribs of the suffocated and on them he will rhythmically press with the weight of his body. The affected subject passively performs respiratory movements, the return of elasticity to the lung walls will ensure inspiration. .

Word of mouth method

In which the lifeguard directly inspires and expires the air from his lungs to those of the patient by the contact between both mouths.

Artificial respiration is an emergency procedure used to assist the unconscious person in breathing. Heart massage is used when you can not hear or feel the heartbeat .

When combined with artificial respiration, it is called cardiopulmonary resuscitation . Since cessation of breathing is followed closely by the stoppage of the heart and vice versa, cardiopulmonary resuscitation is often required to keep the patient alive.
The heart massage itself provides movement of air and pumping blood. For best results, combine the heart massage with forced mouth-to-nose breathing. This requires two people, one to administer the heart massage and one to give mouth-to-nose breathing.

The following emergencies may require artificial respiration and / or heart massage:

Prolonged seizure
Head injury
Electric shock
Clogged air passage (drowning)
Sudden death
Two methods are used. The chest compression technique involves applying force to the chest wall, which pushes the air outward and allows the chest to draw in air.

It is the easiest to do. Forced breathing from mouth to nose is used when the compression technique is not effective, or when the chest is pierced.

Compression of the chest

Steps in the compression of the chest
Feel the pulse or beat of the heart .
Open the mouth and remove the secretions. Check to see if there is any foreign object. If any object is found, remove it if possible. If it is not possible to reach it, execute the Heimlich Maneuver .
Lay the patient on a flat surface with his right side facing down.
Press the chest from side to side. Release it quickly. Repeat every 4 seconds. If done properly, you can hear the air circulating inside and outside. If you can not hear it, start mouth-to-nose resuscitation.
Continue until the patient breathes on their own or while there is a heartbeat .
Steps in mouth-to-nose resuscitation
Perform Steps 1 and 2 of Breast Compression
Stretch your tongue forward and close your mouth. Close your lips with your hand.
Place your mouth on the patient’s nose and blow for 3 seconds. The chest will expand. Release it to allow air to escape.

Continue until the cat breathes on its own or while there is a heartbeat. Artificial respiration techniques

“Word of mouth” technique

Place the victim in a dorsal cube (face up) position smoothly on a hard, smooth surface, or on the ground, without any element (pillow, sack, etc.) under his head.
Kneel at the side of the victim, achieve the opening of the maxilla (mouth), separating the lower jaw to verify the presence of foreign bodies ( dentures , mucus , blood , etc.); In case of checking it clean with fingers wrapped in a handkerchief.
Extend (hyperextend) the head of the victim back so that the chin is up, placing one hand under the neck and another on the forehead, checking for 5 seconds if it breathes and the thorax moves; To do this, bring your face close to the nostrils and hear if you breathe in or close a mirror or the watch face, which will tarnish in the positive case.
If you do not breathe, seal the nostrils with the fingers of the hand on the forehead of the victim (sealed) and blow into the mouth until the chest is raised. If using “mouth-nose”, close with the hand that supports the neck in the mouth and breathe air through the nose.
Blow inside the accident 4 times as fast as possible, withdrawing the mouth to take air and to let out the air that was insufflated. If you do not breathe repeat the operation again; If you still do not breathe, clean the victim’s mouth again to remove foreign bodies. If breathing has not yet been confirmed, place it on its side (with a lateral cube) and clap its hands between both bones to eliminate foreign bodies.
Blow again, repeating the operation, 12 times per minute in the adult and in the small child 20 times per minute. When you begin to breathe, keep your head flexed and do not squeeze your nose.
Pressure technique in the back
If it is impossible to perform the previous techniques “mouth to mouth” or “mouth-nose”, proceed to do the following:

Pressure technique in the back

Pressure technique in the back
Place the victim face down with the head tilted to one side; the arms of the same should be crossed, placing one hand on the other, under the head. The movements of this technique are done in 5 seconds, therefore for each count up to five.
Kneel in front of the victim’s head, placing their hands on the victim’s back with their palms resting on their shoulder blades . Count one.
Without bending the elbows, rock the body forward until the arms are upright. Count two.
Rock the body backwards and slide the hands through the arms of the victim to the elbows. Count three and take it by the elbows, raise your arms towards you. to feel the resistance on the shoulders of the victim. Count four.
Bring the arms to the starting position. Count five. Repeat 12 times per minute (every 5 seconds count
Continue until the victim breathes normally. Control breathing and circulation .
