Electrocardiogram is the abbreviation of ECG that is also known as EKG
by many people. Basically, ECG is a test that checks all the problems
that are related to the heart. They are usually tested with some kind of
electrical activity. This makes the procedure of ECG successful.
Different kind of channels is used for the process of ECG. It all
depends on the condition of the patients that what kind of machine and
with how many channels is required for the ECG of the patient. ECG is
one of the simplest and painless test for the heart problems that
records all the electrical activities of the heart with the help of a
machine with one or more channels efficiently. During the procedure of
ECG, an electric signal is spread usually from the top to the bottom of
the heart with each and every heartbeat. When these electrical signals
spread from the top of the heart to the bottom, all these signals
together help the heart in contracting and pumping the blood and this
process is repeated with the every new heartbeat.
Most of the times, the twelve channel ECG is required for testing the
heart problems of the patients. It always depends on the cardio
conditions of the patients that what how many channels are required for
their ECG. If all the problems of the heart need to be checked with the
help of the electrocardiographs, then the twelve channel ECG is always
recommended. There are many advantages of the twelve channel ECG. There
are twelve channel ECG machines available in the markets as well, so
that the people can do the ECG easily at their homes with the help of
these twelve channel ECG machines. Most of the twelve channel ECG
machines have the following features:
• 12 LED simultaneous acquisition.
• Detection and alarm as well on lead off and low battery.
• Built in ECG stimulator for the purpose of DEMO.
• Unique 6 CH+P Printing mode, very convenient for the physical examination and the printing report on the A4 paper.

Three Channel ECG
ECG is also known as EKG and it is an abbreviation of Electrocardiogram
that is basically a test that checks for all the problems that are
related to the heart with some kind of electrical activity. There is
different kind of electrical activities introduced for the process of
ECG. It all depends on the cardiologist that what kind of electrical
machine he uses for the process of ECG. Different ECG machines are
required for different patients depending on their conditions. ECG is a
very simple and painless test that records the electrical activities of
the heart of the patients very efficiently. In the process of ECG, with
every heartbeat, an electrical signal is spread from the top of the
heart to its bottom. When it travels from the top to the bottom, these
signals causes the heart to contract and pump the blood and this process
keeps on going with every new heartbeat.
Different ECG channels are used by different cardiologists, depending on the cardio conditions of the patients. Most of the times three channel ECG is used for the cardio patients as it has many advantages. There are many machines available in the market that helps in performing the task of the ECG or EKG. Some of the features of these three channel ECG machines are:

Six Channel ECG
An electrocardiogram is utilized for the purpose of monitoring the heart
and its beat. Each and every heart beat can be brought on by means of
impulse which is electrical commonly produced by unique tissues from the
upper chamber of your heart. An electrocardiogram is also known as ECG
or EKG. Its objective is typically to record these kinds of electrical
signs as they pass through your heart. Your personal doctor may utilize
an electrocardiogram to find patterns in the midst of the heartbeats in
addition to tempos to detect different heart circumstances.
Electrocardiographs diagnose this electric impulses linked with the activity of the heart in addition to generate an ECG, the graphical record of the time versus voltage. They are utilized to spot in addition to help out with the treatment of some varieties of heart problems and arrhythmias. In addition they ascertain the patient’s a reaction to the therapy of drugs, also it helps reveal developments as well as improvements in the function of the heart.
Multichannel electrocardiographs record impulses by several leads at the same time and are frequently used rather than single-channel units. A number of electrocardiographs are capable of doing automated dimension in addition to elucidation.

Single Channel ECG
Electrocardiographs are used for the detection of the electrical signals
that are associated with the cardiac activities and for the production
of ECG or Electrocardiograms. ECG is basically a graphic record
of all the voltage versus the time. ECG or EKG is used for the
detection, diagnosis and assisting in the treatment of some types of the
heart diseases and also for the arrhythmias for the determination of
the patient’s response to the drug therapy and for revealing all the
trends and the changes in the functions of the heart. Different kind of
ECG channels has been in use by different physicians, but most of them
have been using the single channel ECG for getting the accurate results
of the hearts. The single channel ECG have been recording the heart
signals from only one lead that makes it really very easy for the
doctors to detect what kind of heart problem the patient is actually
suffering from.
Some of these single channel ECG can also perform the automatic functioning, measurement and interpretation of the ECG as one of the most selectable and optional feature. This has been a great help for all the cardiologists working with the single channel ECG. The single channel ECG consists of the ECG units, cables and the electrodes. These single channel ECG have got the following features usually:
• A 12 lead system including three different types of leads that are bipolar, unipolar and precordial.
• The 12 leads presenting different kind of perspectives of the electrical activities of the heart.
• Produces ECG waveforms in which all the P waves, T waves and QRS complex vary in the amplitude and polarity.

Definition of Blood Vessel Inflammation
The medical term for blood vessel inflammation is vasculitis or
angiitis. Inflammation of veins is called venulitis and inflammation of
arteries is called arteritis. Vasculitis is the term used for a group of
diseases that cause blood vessels inflammation.
Ehow
Features
In vasculitis, the inflammation of blood vessels causes them to become
thicker. This makes it harder for the blood to move through them, and
the supply of oxygen to the tissues is hindered. In extreme cases, the
condition can result in blot clots and aneurysms.
Types
There are many different diseases that feature vasculitis, but affect
different blood vessels and organs. Examples include: Behcet's disease,
Churg-Strauss syndrome, cryoglobulinemia, Kawasaki disease, Takayasu's
arteritis and Henoch-Schönlein purpura.

Fetal Monitoring System
Childbirth is a complex series of mechanism by which a foetus is brought
to the outside world. During gestation mother goes by a number of
physiological changes that aids in maintaining her pregnant status. The
journey that starts from developing embryo leads to delivery of the
foetus. The whole pregnancy period is of 37 weeks. During this
gestational period a mother has to go through regular visits to her
gynaecologist, in those visits the mother undergoes a series of blood
test and ultrasound screening to detect the foetal status. There are
certain invasive tests performed to detect foetal abnormality.
Preserving foetus and maintaining a non hostile environment inside a
mother’s womb is necessary to maintain an effective foetus status.
There are foetal monitors developed to keep a check system on foetus development. There are two types of monitoring systems, external monitoring devices and invasive monitory devices.
External monitors include DOPTONE. Doptone is a Doppler foetal heart rate monitor .It detects the heart rate of a foetus growing inside of a pregnant woman. A foetal stethoscope can also be used for similar purpose but by stethoscope only the examiner can hear the heart beat. In early stages the foetus heart beat corresponds with the mother heart beat however by the end of ninth month the foetal heart beats 155 beats per minute.
The Doppler has a transducer that converts the heart beat of foetus into electric signals that can be heard by examiner and even the mother. Another external monitor used in obstetrics is cardiotocography. It records the mothers’ uterine contractions with the foetal heart beat.

Patient Monitor
In the hospital practice, Patient monitors have provided great
use to doctors to keep an account of patient’s health status. Tracking
the well being position of a patient is important for medical personnel.
Different monitors like ECG MACHINES, EEG MONITOR, B.P APPARATUS, PULSE
OXIMETER and GLUCOMETER are widely used in hospital system.
ECG machines measures the conductivity of a patient’s heart. Electrocardiography i.e. ECG is a graphical presentation of working of a normal heart. It denotes the normal breathing rhythm of the heart and detects abnormality by creating abnormal notches and flat curves in the reading. Patients visiting a hospital for cardiac issues have different wave pattern. By ECG we can diagnose heart valve issues and comes to a conclusion for slow and fast heart rhythms.
EEG stands for electroencephalography is basically a recording of human brain activity and the EEG machine measures the voltage and current generated by a normal brain. EEG consists of multiple thin electrodes that are attached to a human scalp. This device is used to diagnose diseases like epilepsy, brain pathologies, coma and brain death. Tumours and stroke cases are detected through EEG.
B.P Apparatus is a device to monitor ones blood pressure. From B.P Apparatus you can detect heart contractility and relaxibility. It also measures you pulse pressure. There are two readings recoded through this apparatus, systolic reading that determines the pressure heart generates to pump blood through the body.

Blood Pressure Monitor
Living in this fast paced world can get very stressful from time to
time. With the advent of technology and fast food chains we human
beings have gotten lazier and unhealthier than we have ever been in the
past. Couple that with stress and anxiety and you have the perfect
combination for high blood pressure. It is absolutely essential for all
of us to own a blood pressure monitor of our own so that we can keep a check on our health levels.
Even if you are considered healthy, it is nevertheless a good idea to use a blood pressure monitor to keep a check on your day to day blood pressure levels. This can help your doctor when the time for routine checkups come. When it comes to actually purchasing a blood pressure monitor for you there are many types to choose from.
You can always opt for a manual blood pressure monitor, the one that you find on your doctor’s table. It consists of an arm cuff, a squeeze bulb, and a stethoscope. These give you the best and most accurate results but the main problem is that it is much too large to carry around with ease. That is why many people tend to opt for digital monitors with regard to ease of use.
You can choose a finger blood pressure monitor as it is the lightest to carry and doesn’t even require you to roll up your sleeves. It may not give you the most accurate result though. You can also opt for wrist blood pressure monitors, these are highly sensitive to body temperature and movement and so the readings do tend to fluctuate.

Pulse Oximetry | VetGirl Veterinary
Pulse oximetry is a
non-invasive method of measuring the oxygen saturation of hemoglobin
(SpO2) in arterial blood. It it perfect? Is it the gold standard? No:
an arterial blood gas
(ABG) is considered the gold standard. Due to the complexity of
arterial blood gas sampling, it is often reserved for critically ill
canine patients, leaving pulse oximetry the common bedside test for
evaluating oxygenation. That said, in VetGirl’s opinion: pulse oximeter + venous blood gas (VBG) = ABG.
So, how exactly does the pulse oximeter work?
The pulse oximeter calculates the percent of oxygen saturation of hemoglobin in arterial blood using spectrophotometry. The probe passes light through the tissues at two different wavelengths: a red and infrared light absorption. Oxygenated hemoglobin absorbs more infrared light and allows more red light to pass through. Deoxygenated (or reduced) hemoglobin absorbs more red light and allows more infrared light to pass through. The difference in light absorption is calculated and the final figure is displayed as a percentage (SpO2%).
So, why should you care? Because with the non-invasive pulse oximeter, you can correlate your SpO2% to the partial pressure of oxygen in the blood (PaO2) based off the oxyhemoglobin dissociation curve. Bare with us and think back to third-year veterinary school… VetGirl
