What is the primary purpose of using a pulse oximeter in caregiving?

The primary purpose of using a pulse oximeter in caregiving is to assess oxygen saturation in the blood. This device provides a non-invasive method to measure the amount of oxygen carried by hemoglobin in the bloodstream. Monitoring oxygen saturation is crucial as it helps caregivers understand a patient's respiratory efficiency and can indicate whether someone might be experiencing issues such as hypoxia (low oxygen levels).

Although pulse oximeters can give indirectly related information about heart rates, their main function is to provide real-time data about oxygen levels. This information is vital for making informed decisions regarding a patient's care, particularly in cases of respiratory illnesses or conditions that affect oxygenation. Proper assessment of oxygen saturation helps ensure that patients are receiving adequate oxygen, which is essential for their overall health and wellbeing.
