ARTIFICIAL

RESPIRATION- BY SUVEC M.B.B.S

KAPVGMC



artificial respiration, any measure that

causes air to flow in and out of a person's lungs when natural breathing

is inadequate or ceases, as in respiratory paralysis, drowning,

electric shock, choking, gas or smoke

inhalation, or poisoning



MANUAL METHODS

Mouth to mouth Mouth to nose

Mouth to mouth and nose

Mouth to mask

-Bag valve mask

Silvester method Holger Nielsen



T MOUTH TO NOSE ² in maxillofacial

injuries, performing the procedure in water or the remains of vomit in the

mouth TMOUTH TO MOUTH AND NOSE -

Used on infants (usually up to around

1 year old), as this forms the most effective seal



T MOUTH TO MASK ² to reduce cross

infection risk. One popular type is the 'pocket mask'. This may be able to

provide higher tidal volumes than a

Bag Valve

In Drowning do not waste time trying

to "empty water out of the lungs" by jackknifing or rolling on a barrel.



bag valve mask When the air chamber or "bag" is squeezed, the device forces air through into the patient's lungs; when the

bag is released, it self-inflates, drawing in ambient air or a

low pressure oxygen flow supplied

from a regulated cylinder, whilst the patient's lungs deflate to the air through the one way valve



The Silvester Method of artificial respiration

in which the patient is laid on their back, and their arms are raised above their head to aid inhalation and then pressed against their chest to aid exhalation.The procedure is repeated

sixteen times per minute Holger nieslen method:





MECHANICAL METHODS Drinker and Shaw tank Mechanical ventilator

-Transport ventilators

-ICU ventilators -High Frequency ventilator

-Tracheal intubation

-Oesophageal obturator airway

-Cricothyrotomy

-Tracheostomy



Drinker·s method

-iron lung chamber In the iron lung by means of a pump, the air is

withdrawn mechanically to produce a vacuum inside the tank, thus creating negative pressure. This negative pressure leads to expansion of the chest,which causes a decrease in intrapulmonary pressure and flow of ambient air into the lungs. As the vacuum is released, the pressure inside the tank

equalizes to that of the ambient pressure, and the elastic coil of the chest and lungs leads to passive exhalation.



Positive pressure machines

Positive-pressure ventilators work by

increasing the patient's airway

pressure through an endotracheal or tracheostomy tube or tracheoHand-

controlled ventilation



High frequency ventilator

High frequency ventilation is a type of mechanical ventilation that employs very high respiratory rates

(>150 breaths per minute ) and very small tidal volumes (usually below anatomical dead space)



NICU ventilators--Designed with the preterm

neonate in mind

PAP ventilators-- these ventilators are

specifically designed for non-invasive ventilation. this includes ventilators for use at home, in order to treat sleep apnea .

Tracheotomy and tracheostomy are surgical

procedures on the neck to open a direct airway through an incision in the trachea (the windpipe



Tracheal intubation A tube is inserted through the nose (nasotracheal intubation)

or mouth (orotracheal intubation) and

advanced into the trachea Cricothyrotomy where an airway is

inserted through a

surgical opening in

the cricothyroid membrane



Kiss

of

life



Cardiopulmonary resuscitation (CPR) is an emergency medical procedure for a victim of cardiac arrest or, in some

circumstances, respiratory arrest CPR consists of artificial blood

circulation and artificial respiration

(i.e. chest compressions and lung ventilation).



CPR is unlikely to restart the heart , but

rather its purpose is to maintain a flow of oxygenated blood to the brain and the heart, thereby delaying tissue death and

extending the brief window of opportunity for a successful resuscitation without permanent brain damage.

Defibrillation and advanced life support are usually needed to restart the heart .



The best estimate of the heart efficiency

during CPR is 20-30% of normal.

You are breathing oxygen into the lungs.

Your exhaled breath contains 16% oxygen which is close to the 20% contained in the

air you breathe in, while the carbon-di-

oxide stimulate the respiratory center



A universal compression-ventilation ratio (30:2 ) recommended for all single rescuers of

-infant ,child and adult victims (excluding

newborns).Ratio for the two person CPR is 5 :1, at a rate

of 80 compressions per minute

The primary difference between the age groups is that

with adults the rescuer uses two hands for the chest

compressions, while with children it is only one , and

with infants only two fingers ( index and middle fingers).



CPR is only likely to be effective if

commenced within 6 minutes after the blood flow stops,

because permanent brain cell damage

occurs when fresh blood infuses the cells after that time, since the cells of the brain become dormant in as little as 4-6 minutes in an oxygen deprived environment and the

cells are unable to survive the reintroduction of oxygen in a traditional resuscitation

Remember the ABCs

Think ABC - Airway,

- Breathing and

-Circulation

.



AIRWAY: Clear the airway

Put the person on his or her back on a firm surface.

Kneel next to the person's neck and shoulders. Open the person's airway using the head-tilt, chin-lift maneuver . Put your palm on the person's forehead and gently tilt the head back. Then with the other hand, gently lift the chin forward to open the airway.

Check for normal breathing , taking no more than five or 10 seconds: Look for chest motion, listen for breath sounds, and feel for the person's breath on your cheek and ear. Gasping is not considered to be normal breathing. If the person isn't breathing normally and you are trained in CPR, begin mouth-

to-mouth breathing. If you believe the person is unconscious from a heart attack and you haven't been trained in emergency procedures, skip mouth-to-mouth rescue breathing and proceed directly to chest compression



BREATHING:

With the airway open (using the head-tilt, chin-lift maneuver) pinch the nostrils shut for mouth-to-mouth breathing and cover the person's mouth with yours,making a seal.

Prepare to give two rescue breaths. Give the first rescue breath ³ lasting one second ³ and watch to

see if the chest rises . If it does rise, give the second breath. If the chest doesn't rise, repeat the head-tilt,chin-lift maneuver and then give the second breath.



CIRCULATION: Restore blood circulation with chest compressions

Place the heel of one hand over the center of the person's chest, between the nipples .

Place your other hand on top of the first hand. Keep your elbows straight and position your shoulders directly above

your hands . Use your upper body weight (not just your arms) as you push straight down on (compress) the chest 2 inches (approximately 5 centimeters). Push hard and push fast ³ give two compressions per second, or about 100 compressions per

minute. After 30 compressions, tilt the head back and lift the chin up

to open the airway. Prepare to give two rescue breaths. Pinch the nose shut and breathe into the mouth for one second.



Timing devices --They can feature a

metronome (an item carried by many ambulance crews) in order to assist the

rescuer in getting the correct rate.Manual Assist device ² CPREzy

Automatic device- LUCAS



Rhythmic Abdominal Compressions Rhythmic abdominal compression-CPR

works by forcing blood from the blood vessels around the abdominal organs,

an area known to contain about 25 percent of the body's total blood volume. This blood is then redirected to other sites, including the circulation around the heart.



Frequently ribs are broken with the

pressure CPR places on the sternum.Some studies quote up to 30% of

cardiac arrest victims have broken ribs as a result of CPR .

But remember, it's better to have a

cracked rib than be dead.



Can I kill someone if I do CPR

incorrectly?

No. Remember the person in cardiac

arrest is already clinically dead. CPR can only help. Even if it's not done

"letter perfect" it will probably provide some benefit to the victim.



When should I stop CPR?

When help arrives to take over, or the victim starts to move .

CCR (Cardiocerebral Resuscitation) is simply chest compressions without

artificial respiration is the key to

helping someone recover from cardiac arrest.



CPR can double or triple the victim's

chances of survival when commenced immediately

On average, only 5%-10% of people who receive CPR survive .

There has never been a case of HIV transmitted by mouth-to-mouth CPR



If the victim is obviously pregnant or

known to be pregnant , adjust your

hand position to be slightly higher on

the chest
