Pulse oximeters are compact medical devices used to measure blood oxygen saturation (SpO₂) levels and pulse rate quickly and non-invasively. They are widely used in hospitals, clinics, emergency care, and home healthcare settings to monitor respiratory and cardiovascular conditions. Fast and accurate readings help healthcare professionals assess patient oxygen levels and respond promptly when needed.

Designed for convenience and ease of use, pulse oximeters provide instant results through a clear digital display, making them suitable for continuous monitoring and routine health checks. Their portable design allows for easy use in both clinical environments and home care, supporting effective patient monitoring and improved safety.
