CMS50QB Pediatric and Infant Pulse Oximeter with Colour Display
The CONTEC CMS50QB is a fingertip pulse oximeter specifically designed to measure peripheral oxygen saturation (SpO₂) and pulse rate in children. The measuring chamber is adapted to the smaller diameter of children's fingers, allowing the clip to fit securely and provide effective light shielding – an important prerequisite for accurate pulse oximetry measurements.
For the same reason, the device is also suitable for adults with small hands and thin fingers, for whom a standard adult-sized fingertip clip may not provide a sufficiently secure fit.
The device uses a photoelectric oxyhaemoglobin measurement principle with pulse waveform analysis. Its dual-colour OLED display simultaneously shows the numerical SpO₂ and pulse rate values, pulse waveform and pulse bar.
The child-friendly design is complemented by an animal-pattern neck strap and blue or pink colour options, which can help reduce anxiety associated with examinations. The device is powered by a rechargeable button battery, eliminating the need for regular battery replacement.

Product Information
Product name: CONTEC CMS50QB Pediatric Pulse Oximeter
Manufacturer: CONTEC Medical Systems Co., Ltd.
Model / type: CMS50QB
Product category: Fingertip pulse oximeter for children
Measured and displayed parameters: Oxygen saturation (SpO₂), pulse rate (PR), pulse waveform, pulse bar
Display: Dual-colour OLED, 4 display modes, including inverted view
Power supply: Rechargeable button battery with USB charging unit
Device dimensions: 46 × 40 × 29 mm
Colour options: Blue and pink
Wireless data transmission: According to the distributor's specifications, version without Bluetooth connectivity
Target group: Children beyond infancy, as well as adults with small hands and thin fingers
Applications: Home patient monitoring, primary care, paediatric outpatient care, inpatient care and patient transport
Detailed Technical Specifications
Measurement Ranges and Accuracy
SpO₂ measurement range: 0–100%
SpO₂ resolution: 1%
SpO₂ accuracy: ±2% in the 70–100% range; the manufacturer does not specify accuracy below 70%
Pulse rate measurement range: 30–250 bpm
Pulse rate resolution: 1 bpm
Pulse rate accuracy: ±2 bpm or ±2%, whichever is greater
Performance under low perfusion: Measurements can be evaluated down to a pulse modulation of 0.4%; under these conditions, SpO₂ accuracy is ±4%, while pulse rate accuracy is ±2 bpm or ±2%
Ambient light resistance: The difference between measurements taken under artificial or indoor natural light and measurements taken in a dark chamber is less than ±1%
Display and Usability
Display type: Dual-colour OLED with high contrast and good readability in dark environments
Display modes: 4 layouts, including an inverted ("upside down") view, allowing the values to be read while the device remains attached to the child's finger
Displayed information: Oxygen saturation, pulse rate, pulse waveform displayed in blue, and pulse bar
Operation: Single-button operation
Low battery indicator: Dedicated display icon warns of low battery level
Automatic shutdown: If no finger is detected in the measuring chamber, the device switches off after approximately 5 seconds
Power Supply and Operation
Power source: Rechargeable button battery (included)
Charging: Via the supplied charging unit and USB cable, either from a computer/laptop or from the supplied USB power adapter (DC)
Operating voltage: 3.6–4.2 V DC
Current consumption: Less than 80 mA
Battery cycle life: At least 300 charge/discharge cycles
Operating Principle and Classification
Measurement principle: Photoelectric oxyhaemoglobin measurement technology with pulse waveform analysis
Applied part classification: Internally powered device with Type BF applied part
Dimensions and Package Contents
Dimensions
Device length: 46 mm
Device width: 40 mm
Device height: 29 mm
Neck strap: Included, with quick-release buckle; dimensions not specified
Package Contents
1 × CONTEC CMS50QB pediatric pulse oximeter
1 × Rechargeable button battery
1 × Battery charging unit
1 × USB cable
1 × USB power adapter (DC)
1 × Animal-pattern neck strap with quick-release buckle
1 × User manual
Recommended Use and Applications
Reliable oxygen saturation measurements in children require the sensor and finger to be properly fitted without gaps that allow ambient light to enter, and the child should remain still during the measurement. The CMS50QB supports both requirements: its smaller measuring chamber provides a stable fit on smaller fingers, while its child-friendly design can help create a calmer measurement environment.
Typical applications include:
Home monitoring of children receiving temporary or long-term oxygen therapy
Home monitoring of lower respiratory tract infections, including bronchiolitis and pneumonia, as instructed by the treating physician
Monitoring children with asthma during periods of worsening symptoms and following treatment response
Regular monitoring of children with congenital heart disease according to the protocol established by the treating physician
Rapid screening and orientation measurements in paediatric and general practitioner practices, school health services and health visitor services
As a supplementary device in paediatric outpatient clinics, emergency triage and inpatient departments
Paediatric care during ambulance transport and patient transfer
Measurement in adults with small hands and thin fingers where a standard adult fingertip clip does not provide a sufficiently secure fit
Key Benefits
Child-sized measuring chamber: The clip is adapted to smaller finger diameters and provides a secure fit, supporting stable signals and reliable SpO₂ measurements compared with standard adult-sized pulse oximeters
OLED display readable in the dark: No additional lighting is required during nighttime checks, in dimly lit hospital rooms or children's bedrooms
Four display modes: The inverted view allows the measurement to be read from the perspective of the parent or healthcare professional while the device remains on the child's finger
Rechargeable battery: USB charging eliminates the need for regular battery replacement and supports economical long-term operation
Child-friendly design: The animal-pattern neck strap and blue or pink colour options can help reduce anxiety associated with examinations and make measurements easier to perform
Portable solution: The device can be detached from the neck strap using the quick-release buckle and kept readily available during travel or outdoor activities
Energy-efficient operation: The device switches off automatically when no finger is detected, preventing unnecessary battery drain
Professional Information for Accurate Measurements
The manufacturer specifies that measurements are intended to be accurate when the patient is at rest; use during movement or physical activity is not recommended
Strong ambient light, nail polish, artificial nails, cold fingers and poor peripheral perfusion may affect the measured values
In cases of centralisation, particularly low perfusion, severe anaemia, carboxyhaemoglobinaemia or methaemoglobinaemia, pulse oximetry readings should be interpreted with caution
According to published literature, pulse oximetry may overestimate true arterial oxygen saturation in individuals with darker skin pigmentation; this should be taken into account during clinical assessment
The manufacturer does not specify accuracy for displayed values below 70%; a reading in this range requires immediate medical attention
The device is intended for orientation and monitoring measurements and does not replace medical examination, diagnosis or therapeutic decision-making
