Respiratory monitoring involves tracking a person's breathing patterns and lung function to ensure they are healthy. This can include measuring the rate of breaths, the depth of each breath, and the oxygen levels in the blood. Devices like pulse oximeters and spirometers are commonly used for this purpose, providing valuable data to healthcare providers. This monitoring is essential for patients with conditions such as asthma, COPD, or during anesthesia in surgeries. By keeping an eye on respiratory health, medical professionals can detect problems early and adjust treatments as needed, ensuring better outcomes for patients.
