Circulatory system 1

Circulatory system

Circulatory system

The human circulatory system. Red indicates oxygenated blood, blue indicates deoxygenated.

Latin systema cardiovasculare

The circulatory system is an organ system that passes nutrients (such as amino acids and electrolytes), gases,
hormones, blood cells, etc. to and from cells in the body to help fight diseases and help stabilize body temperature
and pH to maintain homeostasis.

This system may be seen strictly as a blood distribution network, but some consider the circulatory system as
composed of the cardiovascular system, which distributes blood,[1] and the lymphatic system,[2] which distributes
lymph. While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood
never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular
system. The most primitive animal phyla lack circulatory systems. The lymphatic system, on the other hand, is an
open system.

Two types of fluids move through the circulatory system: blood and lymph. The blood, heart, and blood vessels form
the cardiovascular system. The lymph, lymph nodes, and lymph vessels form the lymphatic system. The
cardiovascular system and the lymphatic system collectively make up the circulatory system.

Human cardiovascular system
The main components of the human cardiovascular system are the heart and the blood vessels.[3] It includes: the
pulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop"
through the rest of the body to provide oxygenated blood. An average adult contains five to six quarts (roughly 4.7 to
5.7 liters) of blood, which consists of plasma, red blood cells, white blood cells, and platelets. Also, the digestive
system works with the circulatory system to provide the nutrients the system needs to keep the heart pumping.

Pulmonary circulation
The Pulmonary circulation is the portion of the cardiovascular system which transports oxygen-depleted blood away
from the heart, to the lungs, and returns oxygenated blood back to the heart.

Oxygen deprived blood from the vena cava enters the right atrium of the heart and flows through the tricuspid valve
into the right ventricle, from which it is pumped through the pulmonary semilunar valve into the pulmonary arteries
which go to the lungs. Pulmonary veins return the now oxygen-rich blood to the heart, where it enters the left atrium
before flowing through the mitral valve into the left ventricle. Then, oxygen-rich blood from the left ventricle is
pumped out via the aorta, and on to the rest of the body.

Circulatory system 2

Systemic circulation
Systemic circulation is the portion of the cardiovascular system which transports oxygenated blood away from the
heart, to the rest of the body, and returns oxygen-depleted blood back to the heart. Systemic circulation is,
distance-wise, much longer than pulmonary circulation, transporting blood to every part of the body.

Coronary circulation
The coronary circulatory system provides a blood supply to the heart. As it provides oxygenated blood to the heart, it
is by definition a part of the systemic circulatory system.


View from the front, which means the right side of the heart is on the left of the
diagram (and vice-versa)

The heart pumps oxygenated blood to the
body and deoxygenated blood to the lungs.
In the human heart there is one atrium and
one ventricle for each circulation, and with
both a systemic and a pulmonary circulation
there are four chambers in total: left atrium,
left ventricle, right atrium and right
ventricle. The right atrium is the upper
chamber of the right side of the heart. The
blood that is returned to the right atrium is
deoxygenated (poor in oxygen) and passed
into the right ventricle to be pumped
through the pulmonary artery to the lungs
for re-oxygenation and removal of carbon
dioxide. The left atrium receives newly
oxygenated blood from the lungs as well as
the pulmonary vein which is passed into the
strong left ventricle to be pumped through
the aorta to the different organs of the body.

Closed cardiovascular system

The cardiovascular systems of humans are closed, meaning that the blood never leaves the network of blood vessels.
In contrast, oxygen and nutrients diffuse across the blood vessel layers and enters interstitial fluid, which carries
oxygen and nutrients to the target cells, and carbon dioxide and wastes in the opposite direction. The other
component of the circulatory system, the lymphatic system, is not closed. The heart is located in the center of the
body between the two lungs. The reason that the heart beat is felt on the left side is because the left ventricle, on the
left, is pumping.

Measurement techniques
• Electrocardiogram—for cardiac electrophysiology
• Sphygmomanometer and stethoscope—for blood pressure
• Pulse meter—for cardiac function (heart rate, rhythm, dropped beats)
• Pulse—commonly used to determine the heart rate in absence of certain cardiac pathologies
• Heart rate variability -- used to measure variations of time intervals between heart beats
• Nail bed blanching test—test for perfusion
• Vessel cannula or catheter pressure measurement—pulmonary wedge pressure or in older animal experiments.

Oxygen transportation
About 98.5% of the oxygen in a sample of arterial blood in a healthy human breathing air at sea-level pressure is
chemically combined with haemoglobin molecules. About 1.5% is physically dissolved in the other blood liquids
and not connected to Hgb. The haemoglobin molecule is the primary transporter of oxygen in mammals and many
other species.


Other vertebrates
The circulatory systems of all vertebrates, as well as of annelids (for example, earthworms) and cephalopods (squid
and octopus) are closed, just as in humans. Still, the systems of fish, amphibians, reptiles, and birds show various
stages of the evolution of the circulatory system.

In fish, the system has only one circuit, with the blood being pumped through the capillaries of the gills and on to the
capillaries of the body tissues. This is known as single cycle circulation. The heart of fish is therefore only a single
pump (consisting of two chambers).

In amphibians and most reptiles, a double circulatory system is used, but the heart is not always completely
separated into two pumps. Amphibians have a three-chambered heart.

In reptiles, the ventricular septum of the heart is incomplete and the pulmonary artery is equipped with a sphincter
muscle. This allows a second possible route of blood flow. Instead of blood flowing through the pulmonary artery to
the lungs, the sphincter may be contracted to divert this blood flow through the incomplete ventricular septum into
the left ventricle and out through the aorta. This means the blood flows from the capillaries to the heart and back to
the capillaries instead of to the lungs. This process is useful to ectothermic (cold-blooded) animals in the regulation
of their body temperature.

Birds and mammals show complete separation of the heart into two pumps, for a total of four heart chambers; it is
thought that the four-chambered heart of birds evolved independently from that of mammals.

Open circulatory system
The Open Circulatory System is a system in which fluid (called hemolymph) in a cavity called the hemocoel bathes
the organs directly with oxygen and nutrients and there is no distinction between blood and interstitial fluid; this
combined fluid is called hemolymph or haemolymph. Muscular movements by the animal during locomotion can
facilitate hemolymph movement, but diverting flow from one area to another is limited. When the heart relaxes,
blood is drawn back toward the heart through open-ended pores (ostia).

Hemolymph fills all of the interior hemocoel of the body and surrounds all cells. Hemolymph is composed of water,
inorganic salts (mostly Na+, Cl-, K+, Mg2+, and Ca2+), and organic compounds (mostly carbohydrates, proteins, and
lipids). The primary oxygen transporter molecule is hemocyanin.

Infusion pump 1

Infusion pump

A type of infusion pump, manufactured by Fresenius.

An infusion pump infuses fluids, medication or
nutrients into a patient's circulatory system. It is
generally used intravenously, although subcutaneous,
arterial and epidural infusions are occasionally used.

Infusion pumps can administer fluids in ways that
would be impractically expensive or unreliable if
performed manually by nursing staff. For example,
they can administer as little as 0.1 mL per hour
injections (too small for a drip), injections every
minute, injections with repeated boluses requested by
the patient, up to maximum number per hour (e.g. in
patient-controlled analgesia), or fluids whose volumes
vary by the time of day.

Because they can also produce quite high but controlled
pressures, they can inject controlled amounts of fluids
subcutaneously (beneath the skin), or epidurally (just
within the surface of the central nervous system- a very
popular local spinal anesthesia for childbirth).

Types of infusion
The user interface of pumps usually requests details on the type of infusion from the technician or nurse that sets
them up:

• Continuous infusion usually consists of small pulses of infusion, usually between 500 nanoliters and 10000
microliters, depending on the pump's design, with the rate of these pulses depending on the programmed infusion

• Intermittent infusion has a "high" infusion rate, alternating with a low programmable infusion rate to keep the
cannula open. The timings are programmable. This mode is often used to administer antibiotics, or other drugs
that can irritate a blood vessel.

• Patient-controlled is infusion on-demand, usually with a preprogrammed ceiling to avoid intoxication. The rate is
controlled by a pressure pad or button that can be activated by the patient. It is the method of choice for
patient-controlled analgesia (PCA), in which repeated small doses of opioid analgesics are delivered, with the
device coded to stop administration before a dose that may cause hazardous respiratory depression is reached.

• Total parenteral nutrition usually requires an infusion curve similar to normal mealtimes.

Some pumps offer modes in which the amounts can be scaled or controlled based on the time of day. This allows for
circadian cycles which may be required for certain types of medication.

Types of pump

A Baxter International Colleague CX infusion

There are two basic classes of pumps. Large volume pumps can pump
nutrient solutions large enough to feed a patient. Small-volume pumps
infuse hormones, such as insulin, or other medicines, such as opiates.

Within these classes, some pumps are designed to be portable, others
are designed to be used in a hospital, and there are special systems for
charity and battlefield use.

Large-volume pumps usually use some form of peristaltic pump.
Classically, they use computer-controlled rollers compressing a
silicone-rubber tube through which the medicine flows. Another
common form is a set of fingers that press on the tube in sequence.

Small-volume pumps usually use a computer-controlled motor turning
a screw that pushes the plunger on a syringe.

The classic medical improvisation for an infusion pump is to place a
blood pressure cuff around a bag of fluid. The battlefield equivalent is
to place the bag under the patient. The pressure on the bag sets the
infusion pressure. The pressure can actually be read-out at the cuff's
indicator. The problem is that the flow varies dramatically with the
patient's blood pressure (or weight), and the needed pressure varies with the administration route, making this quite
risky for use by an untrained person. Pressures into a vein are usually less than 8 lbf/in² (55 kPa. Epidural and
subcutaneous pressures are usually less than 18 lbf/in² (125 kPa).

Places that must provide the least-expensive care often use pressurized infusion systems. One common system has a
purpose-designed plastic "pressure bottle" pressurized with a large disposable plastic syringe. A combined flow
restrictor, air filter and drip chamber helps a nurse set the flow. The parts are reusable, mass-produced sterile plastic,
and can be produced by the same machines that make plastic soft-drink bottles and caps. A pressure bottle, restrictor
and chamber requires more nursing attention than electronically-controlled pumps. In the areas where these are used,
nurses are often volunteers, or very inexpensive.

The restrictor and high pressure helps control the flow better than the improvised schemes because the high pressure
through the small restrictor orifice reduces the variation of flow caused by patients' blood pressures.

An air filter is an essential safety device in a pressure infusor, to keep air out of the patients' veins: doctors estimate
that 0.55 cm³ of air per kilogram of body weight is enough to kill (200–300 cm³ for adults) by filling the patient's
heart. Small bubbles could cause harm in arteries, but in the veins they pass through the heart and leave in the
patients' lungs. The air filter is just a membrane that passes gas but not fluid or pathogens. When a large air bubble
reaches it, it bleeds off.

Some of the smallest infusion pumps use osmotic power. Basically, a bag of salt solution absorbs water through a
membrane, swelling its volume. The bag presses medicine out. The rate is precisely controlled by the salt
concentrations and pump volume. Osmotic pumps are usually recharged with a syringe.

Spring-powered clockwork infusion pumps have been developed, and are sometimes still used in veterinary work
and for ambulatory small-volume pumps. They generally have one spring to power the infusion, and another for the
alarm bell when the infusion completes.

Battlefields often have a need to perfuse large amounts of fluid quickly, with dramatically changing blood pressures
and patient condition. Specialized infusion pumps have been designed for this purpose, although they have not been

Infusion pump 3

Many infusion pumps are controlled by a small embedded system. They are carefully designed so that no single
cause of failure can harm the patient. For example, most have batteries in case the wall-socket power fails.
Additional hazards are uncontrolled flow causing an overdose, uncontrolled lack of flow, causing an underdose,
reverse flow, which can siphon blood from a patient, and air in the line, which can starve a patient's tissues of
oxygen if it floats to some part of a patient's body.

Safety features available on some pumps
The range of safety features varies widely with the age and make of the pump. A state of the art pump in 2003 may
have the following safety features:

• Certified to have no single point of failure. That is, no single cause of failure should cause the pump to silently
fail to operate correctly. It should at least stop pumping and make at least an audible error indication. This is a
minimum requirement on all human-rated infusion pumps of whatever age. It is not required for veterinary
infusion pumps.

• Batteries, so the pump can operate if the power fails or is unplugged.
• Anti-free-flow devices prevent blood from draining from the patient, or infusate from freely entering the patient,

when the infusion pump is being set-up.
• A "down pressure" sensor will detect when the patient's vein is blocked, or the line to the patient is kinked. This

may be configurable for high (subcutaneous and epidural) or low (venous) applications.
• An "air-in-line" detector. A typical detector will use an ultrasonic transmitter and receiver to detect when air is

being pumped. Some pumps actually measure the volume, and may even have configurable volumes, from 0.1 to
2 ml of air. None of these amounts can cause harm, but sometimes the air can interfere with the infusion of a
low-dose medicine.

• An "up pressure" sensor can detect when the bag or syringe is empty, or even if the bag or syringe is being

• A drug library with customizable programmable limits for individual drugs that that helps to avoid medication

• Mechanisms to avoid uncontrolled flow of drugs in large volume pumps (often in combination with a giving st
based free flow clamp) and increasingly also in syringe pumps (piston-brake)

• Many pumps include an internal electronic log of the last several thousand therapy events. These are usually
tagged with the time and date from the pump's clock. Usually, erasing the log is a feature protected by a security
code, specifically to detect staff abuse of the pump or patient.

• Many makes of infusion pump can be configured to display only a small subset of features while they are
operating, in order to prevent tampering by patients, untrained staff and visitors.

Intravenous therapy 7

Risks of intravenous therapy

Any break in the skin carries a risk of infection. Although IV insertion is an aseptic procedure, skin-dwelling
organisms such as Coagulase-negative staphylococcus or Candida albicans may enter through the insertion site
around the catheter, or bacteria may be accidentally introduced inside the catheter from contaminated equipment.
Moisture introduced to unprotected IV sites through washing or bathing substantially increases the infection risks.

Infection of IV sites is usually local, causing easily visible swelling, redness, and fever. If bacteria do not remain in
one area but spread through the bloodstream, the infection is called septicemia and can be rapid and life-threatening.
An infected central IV poses a higher risk of septicemia, as it can deliver bacteria directly into the central circulation.

Phlebitis is inflammation of a vein that may be caused by infection, the mere presence of a foreign body (the IV
catheter) or the fluids or medication being given. Symptoms are warmth, swelling, pain, and redness around the vein.
The IV device must be removed and if necessary re-inserted into another extremity.

Due to frequent injections and recurring phlebitis, scar tissue can build up along the vein. The peripheral veins of
intravenous drug addicts, and of cancer patients undergoing chemotherapy, become sclerotic and difficult to access
over time, sometimes forming a hard “venous cord”.

Infiltration occurs when an IV fluid accidentally enters the surrounding tissue rather than the vein. It is characterized
by coolness and pallor to the skin as well as localized swelling or edema. It is usually not painful. It is treated by
removing the intravenous access device and elevating the affected limb so that the collected fluids can drain away.
Infiltration is one of the most common adverse effects of IV therapy and is usually not serious unless the infiltrated
fluid is a medication damaging to the surrounding tissue, in which case the incident is known as extravasation.

Fluid overload
This occurs when fluids are given at a higher rate or in a larger volume than the system can absorb or excrete.
Possible consequences include hypertension, heart failure, and pulmonary edema.

Electrolyte imbalance
Administering a too-dilute or too-concentrated solution can disrupt the patient's balance of sodium, potassium,
magnesium, and other electrolytes. Hospital patients usually receive blood tests to monitor these levels.

A blood clot or other solid mass, as well as an air bubble, can be delivered into the circulation through an IV and end
up blocking a vessel; this is called embolism. Peripheral IVs have a low risk of embolism, since large solid masses
cannot travel through a narrow catheter, and it is nearly impossible to inject air through a peripheral IV at a
dangerous rate. The risk is greater with a central IV.

Air bubbles of less than 30 milliliters are thought to dissolve into the circulation harmlessly. Small volumes do not
result in readily detectable symptoms, but ongoing studies hypothesize that these "micro-bubbles" may have some
adverse effects. A larger amount of air, if delivered all at once, can cause life-threatening damage to pulmonary
circulation, or, if extremely large (3-8 milliliters per kilogram of body weight), can stop the heart.

One reason veins are preferred over arteries for intravascular administration is because the flow will pass through the
lungs before passing through the body. Air bubbles can leave the blood through the lungs. A patient with a heart

Intravenous therapy 8

defect causing a right-to-left shunt is vulnerable to embolism from smaller amounts of air. Fatality by air embolism
is vanishingly rare, in part because it is also difficult to diagnose.

Extravasation is the accidental administration of IV infused medicinal drugs into the surrounding tissue which are
caustic to these tissues, either by leakage (e.g. because of brittle veins in very elderly patients), or directly (e.g.
because the needle has punctured the vein and the infusion goes directly into the arm tissue). This occurs more
frequently with chemotherapeutic agents and people who have tuberculosis.

Table 1 Examples of types of incidents involving infusion pumps

Category of incident Examples of incidents

Storage / packaging
● Flat battery due to not charging the pump.
● Set packaging damaged – set contaminated.


● Loss of battery capacity because battery not maintained
according to manufacturer’s instructions.
● Incorrectly replaced seal resulting in fluid ingress.
● Free-flow from volumetric pump because the door contacts
were not checked during the pump’s annual maintenance.

● Fluid ingress into infusion pump.
● Dried infusate on syringe size sensor resulting in incorrect
syringe size being displayed by the pump.

● Set worn out – inaccurate infusion.
● Worn pumping mechanism leading to inaccurate infusion.

Pumping mechanism became loose because the pump was
dropped. The loose mechanism could not hold the set against
the door sufficiently to control the flow.

Performance Infusion pump not performing to specification because the manufacturer had incorrectly set the pumping mechanism.

Design and labelling
A reprint of the user instructions specified a zero instead of the
number one to set the KVO. Users following the new
instructions could not set the pump to KVO.

Quality assurance (QA)
Spare components for detecting when the infusion was near its
end were undersize. If fitted the pump would not signal ‘near
end of infusion’.

User errors ● Misloading administration set.
● Misloading the syringe.
● Setting the wrong rate.
● Confusing primary and secondary rates.
● Not confirming the set rate.
● Not confirming the syringe size.
● Confusing the pump type.
● Not stopping the infusion correctly.
● Not confirming the pump mode.
● Not confirming the configuration of the pump.

Syringe driver

A syringe pump for laboratory use. World
Precision Instruments (WPI) SP120PZ.

A syringe driver or syringe pump is a small infusion pump (some
include infuse and withdraw capability), used to gradually administer
small amounts of fluid (with or without medication) to a patient or for
use in chemical and biomedical research.

The most popular use of syringe drivers is in palliative care, to
continuously administer analgesics (painkillers), antiemetics
(medication to suppress nausea and vomiting) and other drugs. This
prevents periods during which medication levels in the blood are too
high or too low, and avoids the use of multiple tablets (especially in
people who have difficulty swallowing). As the medication is
administered subcutaneously, the area for administration is practically limitless, although edema may interfere with
the action of some drugs.

Syringe drivers are also useful for delivering IV medications over several minutes. In the case of a medication which
should be slowly pushed in over the course of several minutes, this device saves staff time and reduces errors.

Syringe pumps are also useful in microfluidic applications, such as microreactor design and testing, and also in
chemistry for slow incorporation of a fixed volume of fluid into a solution. In enzyme kinetics syringe drivers can be
used to observe rapid kinetics as part of a stopped-flow apparatus.[1]
