Introduction
Handheld pulse oximeters are compact and portable medical devices used for measuring the oxygen saturation level (SpO2) and pulse rate of patients. These devices are essential in various healthcare settings, providing critical information about a patient’s respiratory status.
Functionality of Handheld Pulse Oximeters
The primary function of a handheld pulse oximeter is to measure oxygen saturation and pulse rate noninvasively. It operates by emitting infrared and red light through a patient's finger, with sensors measuring the absorption of these lights to calculate SpO2 and pulse rate.
Clinical Applications
Handheld pulse oximeters are used in various clinical settings such as:
- Emergency rooms for rapid assessment of oxygen saturation
- Operating rooms for continuous monitoring during surgeries
- ICUs for constant vigilance of patient’s respiratory status
- Home healthcare for patients with chronic respiratory conditions
Advantages of Handheld Devices
Handheld pulse oximeters offer several benefits, including:
- Portability allowing use in a variety of settings
- Ease of use with minimal training required
- Immediate display of results, beneficial for quick decision-making
- High accuracy and reliability in readings
Leis Company Solutions
Leis Company provides a range of handheld pulse oximeters designed for diverse medical needs. Their flagship products include:
- Leis OxM1: Featuring a durable design with Bluetooth connectivity for data transfer

Numerical Analysis
The accuracy of handheld pulse oximeters is often expressed in terms of the Root Mean Square (RMS) error, typically in the range of ±2% for SpO2 measurements. The devices are capable of operating in conditions with a perfusion index of 0.4% to 20%, ensuring reliable measurements across various patient profiles.
