Critical Care Monitoring – EtCO2 / SpO2

Pulse oximetry is one of the most useful practices in the world of critical care medicine, allowing professionals to get a quick read on blood oxygen levels and use that data in diagnosis and in determining the need for supplemental oxygen. Because of their simplicity, pulse oximeters are common in several healthcare service levels ranging from ICU / critical care (to monitor the oxygenation of a patient) to recovery after reconstructive (to ensure oxygenated blood is reaching affected areas).

However, oximetry has its limitations – it can only provide so much information, and sometimes, other tools are required to ensure patient health. Pulse oximetry works by refraction and only measures hemoglobin (oxygenated blood) saturation – not ventilation or metabolism of the oxygen. Sometimes, an oximeter alone doesn’t give you the entire picture of data needed to make critical medical decisions. For example, in patients with severe anemia, the blood can be 100% saturated and will give an oximeter reading as such, but will not be effective because blood that has been affected by severe anemia, even at full saturation, will not contain enough oxygen to be effective within the body.


A common supplement and method used in conjunction with oximetry is capnography monitoring. One of the issues with an oximeter is that you’re only measuring oxygen levels in blood - not the concentration or pressure of carbon dioxide, which are critical for respiratory function (the removal of CO2 from the body). You could still have a very high oxygen saturation number, but if the CO2 isn’t being removed from the bloodstream, that will eventually cause several health concerns. In order to be able to get the full picture of respiratory health, you’ll have to be able to gauge both EtCO2 concentrations and Sp02 (blood oxygen saturation).

According to the American Society of Anesthesiologists, 93% of avoidable anesthesia mishaps can be prevented by employing both a pulse oximeter and capnography monitor. These two tools in conjunction give a much better gauge of respiratory health then either device can provide alone.

In addition to having the largest selection of oximetry devices you’ll find anywhere, Concord Health Supply offers several devices for CO2 monitoring including our critical care EtCO2 oximeter, the LifeSense Tabletop Capnography EtCO2 and Pulse Oximetry monitor, and the Nonin Handheld CO2 and Pulse Oximetry Monitor. Check out our selection today to get both capabilities in one device.

LifeSense Tabletop Capnography and Pulse Oximetry Monitor

Capnography is becoming recognized as a critical component of patient monitoring. Capnography is the measurement of carbon dioxide concentration within exhaled gases, and serves as a monitor of partial pressure in the arterial blood. Paramedics and medical professionals utilize capnography monitoring to ensure that respiration remains steady during intubation and during anesthesia – a rise in the ETC02 levels can be an indicator of hypoventilation, drops can indicate hyperventilation. Particularly in critical care environments and with patients who have pre-existing respiratory issues, a capnography monitor can prove to be a life-saving tool by helping to diagnose these issues swiftly.

Capnography was once something limited to only the ICU, but this capability is now available in a consumer product. The LifeSense Tabletop Capnography and Pulse Oximetry Monitor is one of the only products available which allows for continuous EtCO2 monitoring in a compact package. Engineered by the experts at Nonin, the LifeSense Monitor provides accurate EtC02 and Sp02 monitoring in seconds – a key component in critical care situations.

In addition to accurate monitoring of EtCO2 on the first breath, the LifeSense monitor offers a widescreen, touch-panel display with continuous monitoring and waveform display, allowing accurate readings down to the second. This waveform is monitored for 4 hours with trending monitoring, giving medical professionals the data they need to make accurate decisions regarding the care of their patients. The widescreen display also delivers numerical data display through its backlit LCD, with both audible and visual alarms, offering an unmatched level of monitoring and making it easy for medical professionals to access that data. Data can also be exported via RS-232, offering yet even more capability to this device.

Nonin Onyx Vantage 9590

A digital pulse oximeter is a device used to measure the percentage of oxygenated hemoglobin in a person's blood. It works by measuring the properties of light absorption of hemoglobin using a source of infrared light. Hemoglobin is responsible for delivering oxygen to cells throughout the body. When oxygen levels are low, a person may feel weak. It may be a sign of a serious heart condition.

Regular use of oximeters takes place in professional medical settings by doctors or dentists. However, owning a home monitor may be beneficial as well. Being able to take an oxygen saturation measurement throughout the day will reveal if there are times when oxygenation levels fall too low and require correction. It may be used by individuals with COPD, sleep apnea, or those who participate in sports like skiing or rock climbing. When necessary, it will help a doctor uncover an effective plan of treatment.

How Pulse Oximeters Help Diabetics

How Oximeters Help Diabetics

People with diabetes are 20 times more likely to experience peripheral arterial disease (PAD) than the average population. PAD is a condition in which there is a build-up of plaque in the arteries that carry blood to the organs, limbs and head. Plaque hardens and narrows the arteries over time which means that the flow of oxygen to vital tissues and organs becomes limited. Complications can include gangrene and amputation. Knowing whether or not the blood is sufficiently saturated with oxygen can help diabetics stay a step ahead of these debilitating problems. A pulse oximeter is an easy-to-use tool that can alert the patient or health care provider to low levels of oxygen in the blood, and help prevent dire complications from arterial disease in diabetics.

What Is a Pulse Oximeter?

A pulse oximeter is a clip-on device that may be attached to a finger. On one side is a source for both infrared and red light, which helps distinguish between oxygen-rich blood and oxygen-depleted blood as it pulses through the blood vessels. On the other side is a light detector with a microprocessor which compares and calculates the difference, resulting in a digital readout. Generally speaking, a reading of 96%-100% indicates blood that is sufficiently saturated with oxygen. Below 90% can be cause for concern.

Why Use a Pulse Oximeter?

Tissues that experience oxygen deprivation are susceptible to degradation. A pulse oximeter is a simple way to gauge if blood is saturated with enough oxygen to keep tissue healthy. There are a variety of advantages to using a finger pulse oximeter. They include:

•    It is quick. Oxygen level displays immediately
•    It is non-invasive
•    Results are reproducible
•    It is accurate
•    It requires no expertise to use

How Does It Work?

A pulse oximeter simply clips on to your finger. An LED read out will show your results and any other display information. There are a variety of portable models with features such as one-button operation, automatic shut-off and low battery alert. For those requiring constant medical alerts, tabletop oximeters often allow constant monitoring and functions such as medical alarms to alert medical professionals when oxygen levels become dangerously low.

Why Measuring Oxygen Levels is Important to a Diabetic

Diabetes is a leading cause of leg amputation, chronic kidney failure, blindness, stroke and heart attack. A common symptom of diabetes is poor circulation. With diminished circulation, tissues fail to receive the oxygen necessary to stay vital. This situation can eventually lead to hypoxemia, or low oxygen saturation, leaving the diabetic vulnerable to the consequences of compromised tissue such as gangrene or amputation. A fingertip oximeter can quickly and easily measure oxygen saturation in the blood, helping patient and physician alike stay ahead of unwelcome developments.

When Is a Pulse Oximeter a Good Idea?

When a diabetic is experiencing symptoms of nerve damage, a pulse oximeter may be able to offer information that would be useful for heading off further impairment. Symptoms of low oxygen saturation and subsequent nerve damage may present as:

• Persistent feeling of "pins and needles"
• Leg pain when climbing stairs
• Muscle weakness in legs
• Bone and joint pain
• Numbness or a reduced ability to feel pain
• Cuts that are slow or hard to heal

Early Detection Is Best

While symptoms may not necessarily mean that there is actual nerve damage, early diagnosis and treatment help to control symptoms and prevent further problems down the road. A pulse oximeter effectively and instantly gauges a critical component of circulatory health. Measuring blood oxygen saturation with a digital oximeter is a convenient and cost effective way to help decrease the possible catastrophic risks of diabetes.

Pulse Oximetry 101: History, Functions & Uses

A Brief History of Pulse Oximetry

Pulse Oximetry, which is a method for measuring and monitoring the oxygen saturation or percentage of oxygen in a patient's blood, has been around since the 1970s. Pulse Oximeters first became commercially available in the early 1980s. It was then that this technology started being used widely in hospital operating rooms for monitoring oxygen levels of surgical patients undergoing procedures involving anesthesia.

Pulse Oximetry 101: History, Functions & UsesPrior to the availability of pulse-ox equipment, blood oxygen levels of patients in operating theaters were determined by doing arterial blood gas testing in a laboratory. This process of collection and processing of blood was time consuming; often taking longer than it would take for a patient to go brain dead from lack of oxygen while on the operating table.

By the middle 1980s, pulse oximetry was being used in all operating rooms in the U.S. where anesthesia was being used. This was an incredibly important advancement for surgeons and anesthetists in providing more accurate patient monitoring. Soon the use of these devices became common in recovery rooms, intensive care units and even on emergency vehicles responding to medical emergencies in the field.

Now, pulse oximeter come in a variety of sizes and can be used by hospitals, EMTs, in-house patients and those who are into adventure sports. The main purpose is to monitor the blood oxygen saturation level in the blood.

Saving Lives Also Extends to CO2 Monitoring

Besides the ability to get accurate readings on SpO2, another important step in patient care came through the advancements made in capnography, which is the discipline involved in measuring and monitoring carbon dioxide (CO2) output of a patient. The ability to have a precise CO2 measurement is also an important factor in the management of administering anesthesia during a surgical procedure. In the field, EMS crews use capnography when putting an endotrachael tube in place to ensure it's located properly. An improperly placed airway can lead to patient death and, with an accurate readout of CO2 gases, proper placement can be verified.

Sleep apnea, which is breathing disorder affecting individuals while they're sleeping, often goes undetected by those suffering from the condition. It involves bouts of shallow breathing or stopped breathing that can last anywhere from several seconds to minutes. In cases where sleep apnea is suspected in a patient, pulse oximetry can be used in the patient's home to determine if blood oxygen levels are being compromised during nighttime sleep. Even though an individual may be ignorant to the sleep apnea from which he/she is suffering, the effects of low oxygen in the blood and lack of deep sleep will be debilitating.

Why Measure Blood Oxygen Levels?

Oxygen saturation is a term that refers to the concentration of O2 in the blood, expressed as a percentage. Another word for oxygen saturation is oxygenation, and it is usually written in the medical community as SpO2. The human body requires and automatically strives for a precise balance of oxygen in the blood. Normal levels of oxygenation in arterial blood are between 95-100%, with anything lower than 90% considered hypoxic. A blood oxygen level of less than 80% is a serious situation that could soon result in organs such as the heart and/or brain deteriorating to the point of causing cardiac or respiratory arrest.

Pulse Oximeters are able to precisely measure the blood's SpO2 in a patient wearing the device on a finger. The pulse-ox device sends out two separate light beams, one red and one infrared, which travel from one side of the finger to the other, where it strikes a photo-detector. The measurement made is related to how these two light beams change when traveling through the arterial blood in the finger and a relationship is made between the difference between oxygen poor venous blood and oxygen rich arterial blood.
