Patients' and GPs' views and expectations of home monitoring with a pulse oximeter: a mixed-methods process evaluation of a pilot randomised controlled trial (2024)

Abstract

BACKGROUND: Research on how home monitoring with a pulse oximeter is executed and experienced by patients with an acute illness such as COVID-19 and their GPs is scarce.

AIM: To examine the process of structured home monitoring with a pulse oximeter for patients with COVID-19, their caregivers, and their GPs.

DESIGN AND SETTING: This was a mixed-method process evaluation alongside a pilot feasibility randomised controlled trial. Patients drawn from a general practice setting, with COVID-19, and aged ≥40 years with cardiovascular comorbidities were included.

METHOD: Quantitative trial data from 21 intervention group participants (age 63.2 years) were used, plus qualitative data from semi-structured interviews with 15 patients (age 62.9 years), eight informal caregivers, and 10 GPs.

RESULTS: Adherence to the intervention was very high; 97.6% of protocolised peripheral oxygen saturation (SpO2) measurements in the first 14 days until admission to hospital were recorded (677/694, median daily per patient 2.7). Three identified themes from the interviews were: (a) user-friendliness of home monitoring: easy use of the pulse oximeter and patient preference of a three times daily measurement scheme; (b) patient empowerment: pulse oximeter use enhanced patient self-assurance and empowered patients and informal caregivers in disease management; and (c) added value to current clinical decision making. GPs perceived the pulse oximeter as a useful diagnostic tool and did not experience any additional workload. They felt more secure with remote monitoring with a pulse oximeter than only phone-based monitoring, but emphasised the need to keep an overall view on the patient's condition.

CONCLUSION: Structured home monitoring by pulse oximetry supports patients and their informal caregivers in managing, and GPs in monitoring, acute COVID-19 disease. It appears suitable for use in acutely ill patients in general practice.

    FAQs

    What monitoring technique was done along with pulse oximetry? ›

    Medical uses. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements ...

    What is a pulse oximeter used to measure the patients? ›

    Basically, pulse oximetry is a painless, noninvasive method of measuring the saturation of oxygen in a person's blood. Oxygen saturation is a crucial measure of how well the lungs are working.

    What do pulse oximetry monitoring devices give an estimate of? ›

    Pulse oximetry is a test used to measure the oxygen level (oxygen saturation) of the blood. It's an easy, painless measure of how well oxygen is being sent to parts of your body furthest from your heart, such as the arms and legs.

    What are the three main probe sites that may be used for pulse oximetry monitoring? ›

    Pulse oximeters are often applied to areas of thin skin such as an ear lobe or finger tip. Fingernail polish and even different types of skin pigmentation may skew pulse oximeter results.

    What is the methodology of pulse oximeter? ›

    Non -invasive method of pulse oximetry makes use of red and infra -red LEDs for illumination of light at different wavelengths [3]. Absorption of infrared or red-light can be decided based on the type of haemoglobin and their optical property and hence the other will be passed through.

    What are the methods of oxygen monitoring? ›

    Blood oxygen saturation can be determined invasively by blood gas analysis, or non-invasively by pulse oximetry. Blood gas analysis (BGA) is an invasive method for assessing the oxygenation capacity of the lungs or the circulatory status and acid-base balance in the blood.

    What 3 things does a pulse oximeter measure? ›

    A pulse oximeter measures your blood oxygen levels and pulse. A low level of oxygen saturation may occur if you have certain health conditions. Your skin tone may also affect your reading. Pulse oximetry is a noninvasive test that measures the oxygen saturation level of your blood.

    What is the guideline for pulse oximeter? ›

    What is a pulse oximeter used to monitor? ›

    The pulse oximeter, or Pulse Ox, is an electronic device that measures the saturation of oxygen carried in your red blood cells. Pulse oximeters can be attached to your fingers, forehead, nose, foot, ears or toes.

    What principle does a pulse oximeter follow? ›

    Pulse oximetry is based on the principle that O2Hb absorbs more near-IR light than HHb, and HHb absorbs more red light than O2Hb.

    Does pulse oximetry provide a good guide to patients' ventilation? ›

    Introduction: Pulse oximetry (SpO2) measures oxygen saturation but not alveolar ventilation.

    Will AFib show up on a pulse oximeter? ›

    Hospital-grade pulse oximeters can read through perfusing cardiac arrhythmias such as atrial fibrillation and premature atrial or ventricular contractions.

    What is the lowest oxygen saturation before death? ›

    An SpO2 level of 92 percent is considered the lowest clinically acceptable level by established norms of clinical practice at any age, except in cases of chronic lung disease, where it is 88 percent. Death can occur due to hypoxemia at any level less than 88 percent.

    What is a bad pi in an oximeter? ›

    This is called the perfusion index and it determines the pulse strength at the sensor site. The normal perfusion index (PI) ranges from 0.02% to 20%. If the perfusion index is at or below 0.4% showing weak pulse strength, then the oximeter reading can be unreliable.

    What is the monitoring device used to detect oxygen saturation? ›

    The pulse oximeter, or Pulse Ox, is an electronic device that measures the saturation of oxygen carried in your red blood cells.

    What is oximetry monitoring? ›

    Pulse oximetry is sometimes referred to as the fifth vital sign; it is a quick and non-invasive monitoring technique that measures the oxygen saturation in the blood by shining light at specific wavelengths through tissue, most commonly the fingernail bed.

    What is a method of monitoring blood oxygenation levels? ›

    A pulse oximeter can measure oxygen saturation. It is a noninvasive device placed over a person's finger. It measures light wavelengths to determine the ratio of the current levels of oxygenated hemoglobin to deoxygenated hemoglobin. The use of pulse oximetry has become a standard of care in medicine.

    What is the method for monitoring dissolved oxygen? ›

    The most popular method for dissolved oxygen measurements is with a dissolved oxygen meter and sensor. While the general categories of dissolved oxygen sensors are optical and electrochemical, electrochemical sensors can be further broken down into polarographic, pulsed polarographic and galvanic sensors.
