New & Used Pulse Oximeter

Tips for buying Pulse Oximeter

1. These units can either be stand-alone or a module in a larger patient monitor.
2. Most pulse oximeters can interface with printers, recorders, computers, or multiparameter monitoring systems. It is important to make sure that the purchased unit is compatible with existing equipment.
3. The unit should display at least 70% to 100% SpO₂ values with an accuracy of ±3%. Pulse-rate measurements should be accurate within ±5 beats per minute within the range of 30-240 bpm.
4. The probes should provide accurate measurements while tolerating probe movement caused by the patients or clinicians.
5. In addition to SpO₂ and pulse rate, the oximeter should also display pulse strength and low battery.
6. Audible and visual alarms should alert for high and low SpO₂/pulse rate, sensor off, and low battery.
7. These units usually operate on AC power, and many have battery backup as well. The unit should switch automatically to battery power if line power fails.
8. Units intended for transport within the facility should operate at least four hours without charging.
9. Units intended for transport outside the facility should operate at least eight hours without charging.
10. In case of an oximeter that is unable to obtain accurate readings, there should be a clear indication, preferably with the reason.
