    Pulsar portable pulse oximeters are diagnostic medical devices for measuring the level of saturation with oxygen in capillary blood (SpO2) and pulse rate. Pulse oximeters are non-invasive measuring instruments that are simple and easy to use. The principle of a pulse oximeter is based on transillumination of tissues with light beams with separation at red and infrared wavelengths, pulse wave digitization and signal quality control.

    Pulsar-M2 pulse oximeter is apnea monitor with 24-hour recording of photoplethysmogram, spirogram, body position indicator with data storage in the built-in memory and their subsequent transfer and analysis to PC. The device records the state of apnea/hypopnea with determination of indices of apnea/hypopnea and desaturation. The device is certified.

    The following protocols are available:

    • 24-hour monitoring;
    • sleep monitoring;
    • stress.

    Monitoring protocols provide statistical reports characterizing oxygen status of organism with time spent by patient in various zones of saturation and pulse rate, apnea/hypapnea index, desaturation index and other indicators with a clear graphical presentation, providing full screening “at a glance”. Long-term monitoring of SPO2 and pulse rate makes it possible to objectively confirm hypoxia, identify conditions and time of its occurrence, and reasonably select groups of patients for subsequent referral to cardiorespiratory monitoring and/or polysomnographic research.

    Stress protocol of the device provides control of effect of 6-minute step test, standardized bicycle ergometric exercise, procedures in a pressure chamber, “Mountain air” procedure, allows for assessing the patient’s physical capabilities, and making a conclusion about the degree of respiratory failure in accordance with the instructions of the Ministry of Health of the Republic of Belarus “Method for Determining the Severity of Chronic Respiratory Failure in Patients with Chronic Obstructive Pulmonary Disease”.
