Blog — monitoring accessories, explained for the people who buy and maintain them
Placement guides, sizing charts, platform comparisons and procurement checklists from the factory floor: written for biomedical engineers, clinical educators and distributors who specify SpO2 sensors, ECG cables, NIBP cuffs and the rest of the monitoring shelf.
ECG Lead Placement Guide: Limb Leads, Chest Leads, Monitoring Positions
Where ECG leads actually go: limb and chest lead positions, Mason-Likar torso placement, 3/5-lead monitoring setups and the reversal errors to avoid.
What Is SpO2? Oxygen Saturation Explained in Plain Language
SpO2 explained: what the percentage means, how it differs from SaO2 and PaO2, typical ranges and why a reading can mislead. A plain-language primer.
Normal SpO2 Levels: Ranges by Age, Sleep, Altitude and Condition
What counts as a normal SpO2 range: healthy adults and children, sleep, altitude, and why some patients have clinician-set targets below 95%.
How Does a Pulse Oximeter Work? The Two-Light Measurement Explained
Red and infrared light, the pulsatile trick, the ratio of ratios and empirical calibration: how a pulse oximeter turns light into an SpO2 number.
ECG Electrode Placement Guide: Landmarks, Colours and Classic Errors
Electrode-by-electrode placement: skin prep, limb and V1–V6 chest landmarks, AHA vs IEC colours, and the placement errors that distort tracings.
12-Lead ECG Interpretation Basics: A Systematic Reading Approach
A beginner's systematic approach to the 12-lead ECG: calibration checks, rate, rhythm, axis, intervals and morphology — educational overview.
Types of Medical Temperature Probes: Technologies, Sites and Series
Thermistor, thermocouple and RTD probes; skin, general-purpose and warmer probes; YSI 400/700 series conventions and how departments choose.
Pulse Oximeter Accuracy: What the ±2% Figure Means and What Disturbs It
How oximeter accuracy is specified (Arms over 70–100%) and what disturbs it: motion, low perfusion, dyshaemoglobins, fit, nails and ambient light.
Mainstream vs Sidestream Capnography: Response, Dead Space, Use Cases
Mainstream and sidestream capnography compared: measurement site, response time, dead space, patient types, failure modes and consumable stocking.
Masimo vs Nellcor SpO2: Platforms, Connectors and Standardisation
A neutral comparison of the two oximetry platforms: sensor ecosystems, connectors, installed-base thinking and how compatible sensors fit. No verdicts.
NIBP Cuff Size Chart: Bladder Sizing by Arm Circumference
The NIBP cuff size chart: bladder width/length rules, size ranges from neonatal to thigh, and why the wrong size changes the reading, not the comfort.
Disposable vs Reusable SpO2 Sensors: Cost, Hygiene and When Each Wins
Disposable vs reusable SpO2 sensors compared on infection control, durability, true cost per monitored day and department fit — plus the hybrid strategy.
