CMS-50QA Pulse Oximeter Fingertip with Alarm for Pediatrics

Pulse Oximeter Fingertip with Alarm for Pediatrics is the latest popular product. It is specially designed for children. CMS-50QA Pulse Oximeter Fingertip with Alarm for Pediatrics can detect pulse rate and SpO2 at the same time. It occupies a very small area and is easy to carry around. It adopts new software algorithm and sensors specially designed for children’s physical parameters.

The finger pulse oximeter is also calibrated for children’s thinner skin surfaces, which may be only 0.3 inches (8 mm). In particular, the opening of the oxygen saturation meter for inserting fingers is narrowed for pediatric care and pediatric care. This helps to prevent ambient light from entering the orifice, which may result in inaccurate readings. This product is recommended for children aged 2 to 13, with a minimum weight of 35 pounds or 16 kilograms. Bright LCD display for easy viewing of high contrast.

The most innovative feature of the product is its built-in heart tracker. This auditory spot helps track the beating of the heart without having to look at the monitor visually. It also includes an audible alarm that detects when the heart rate or SpO2 exceeds the preset specification. This equipment is only used for sports and / or aviation purposes. Pulse Oximeter Fingertip with Alarm for Pediatrics has a 1-year limited warranty.Pulse oximetry provides a readily available, easy-to-use, noninvasive method for measurement of pulse oxygen saturation (Spo2) which will be obtained by placement of alittle probe on the finger, toe, or ear lobe of a patient. In neonates and infants, probes can also be placed on the palms, feet, arms, cheeks, tongue, penis, nose, or septum .

Pulse Oximetry

Pulse oximetry provides a readily available, easy-to-use, noninvasive method for measurement of pulse oxygen saturation (Spo2) which will be obtained by placement of alittle probe on the finger, toe, or ear lobe of a patient. In neonates and infants, probes can also be placed on the palms, feet, arms, cheeks, tongue, penis, nose, or septum . Small, portable pulse oximetry probes are often applied to patients of any size, from premature neonates to the most important adults, in virtually any setting, from outpatient offices and hospital settings to mountaineering expeditions. the primary practical pulse oximeter became commercially available in 1983. Obtaining Spo2 measurements is now so simple that it’s commonly mentioned because the “fifth” sign .

The basic technology behind pulse oximetry is that the photoplethysmographic (PPG) waveform. The PPG waveform is an amplified and highly filtered measurement of sunshine absorption by local tissue over time. At a minimum, all modern pulse oximeters extract and display SpO2 and pulse from the PPG waveform every 3 to six seconds; some display the PPG waveform also . One side of the heart beat oximeter probe contains 2 light-emitting diodes that transmit 2 wavelengths of sunshine , and therefore the other side contains a photodetector. Red light at 660 nm and near-infrared (NIR) light at 940 nm is transmitted through intervening tissue (skin, arteries, capillaries, veins, bone, and fat), with the sunshine not absorbed during this pathway detected by the photodetector on the other side. samples of small, portable and disposable, elasticized pulse oximeter probes are shown in Fig 1.

Pulse Oximetry in Pediatric Practice

The introduction of pulse oximetry in clinical practice has allowed for easy , noninvasive, and fairly accurate estimation of arterial oxygen saturation. Pulse oximetry is routinely utilized in the emergency department, the pediatric ward, and in pediatric intensive and perioperative care. However, clinically relevant principles and inherent limitations of the tactic aren’t always well understood by health care professionals caring for youngsters .

The calculation of the share of arterial oxyhemoglobin is predicated on the distinct characteristics of sunshine absorption within the red and infrared spectra by oxygenated versus deoxygenated hemoglobin and takes advantage of the variation in light absorption caused by the pulsatility of blood . Computation of oxygen saturation is achieved with the utilization of calibration algorithms. Safe use of pulse oximetry requires knowledge of its limitations, which include motion artifacts, poor perfusion at the location of measurement, irregular rhythms, ambient light or electromagnetic interference, skin pigmentation, nail enamel , calibration assumptions, probe positioning, delay in detecting hypoxic events, venous pulsation, intravenous dyes, and presence of abnormal hemoglobin molecules.

In this review we describe the physiologic principles and limitations of pulse oximetry, discuss normal values, and highlight its importance in common pediatric diseases, during which the principle mechanism of hypoxemia is ventilation/perfusion mismatch (eg, asthma exacerbation, acute bronchiolitis, pneumonia) versus hypoventilation (eg, laryngotracheitis, vocal fold dysfunction, foreign-body aspiration within the larynx or trachea). Additional technologic advancements in pulse oximetry and its incorporation into evidence-based clinical algorithms will improve the efficiency of the tactic in daily pediatric practice.
