Measurement of oxygen saturation is one of the primary steps of patient care. This parameter of oxygen saturation (spO2) refers to the quantification of the concentration of oxygen-carrying hemoglobin in the blood in relation to the concentration of hemoglobin free from oxygen. Ideally, a person’s oxygen saturation should be between 95 to 100%. However, a low oxygen saturation indicates hypoxemia which can further lead to acute organ failure thus it is essential to measure it regularly, especially in patients suffering from lung disorders. In this regard, pulse oximeters are the most effective medical devices that can be employed to do this job. Let us understand how they work along with some of the best pulse oximeters available in the US market.

Statistics Regarding Chronic Obstructive Pulmonary Disease in the US

In the United States alone, approximately 34 million people are presently living with respiratory disorders as per the statistics provided by the American Lung Association. These disorders are inclusive of asthma, emphysema, as well as chronic obstructive pulmonary disease (COPD).

What is a Pulse Oximeter?

A pulse oximeter is a non-invasive clip-like device that is employed for the measurement of blood oxygen level as well as pulse rate. It works by getting attached to a body part, commonly to the finger. This way, an estimation of oxygen carrying ability of the blood particularly towards the limbs can be made.

Who Needs a Pulse Oximeter?

Pulse oximeters have high utilization with patients suffering from the following conditions:

   ● Asthma

   ● Pneumonia

   ● Lung cancer

   ● Anemia

   ● Chronic obstructive pulmonary disease (COPD)

   ● Heart attack or failure

   ● Congenital heart disease 

Advantages of a Pulse Oximeter

Pulse oximeters provide the following advantages:

   ● Evaluation of the breathing capacity of the lungs

   ● Assessment of the efficacy of a new medication on the lungs

   ● Monitoring of oxygen levels in the body during a surgical procedure

   ● Determination of the need for oxygen supplementation in the patient

   ● Determination of a person’s capability to tolerate enhanced physical activity

   ● Assessment of the efficiency of a ventilator

Working on a Pulse Oximeter

A pulse oximeter works on the principles of spectrophotometry. It does its job by measuring the alterations in light absorption by the blood. This is done by bombarding the finger with a light coming from the cold light source. Relative absorption of this light is estimated which gives away oxygen saturation.

How to Use a Pulse Oximeter?

As pulse oximeters are designed to be suitable for both inpatient as well as outpatient settings, these are uncomplicated to operate. The following steps should be kept in mind while using a pulse oximeter:

   ● The patient is asked to remove nail polish or any type of jewelry.

   ● Make sure the patient is fully relaxed and her or his hand is warm.

   ● Keep the hand below the heart level and clip the device to the finger. It can also be attached to the patient’s earlobe or toe.

   ● The pulse oximeter reads the oxygen saturation and displays it on LCD which should be recorded.

   ● Once the reading has been taken, the pulse oximeter should be removed.
