Blood gas analyzer is an analytical medical device used to measure the partial pressure of different gasses such as O2, CO2 and others in an arterial blood sample. This device can be found in difference health care department including respiratory therapy departments, operating theatres clinical laboratories, ICU, and physician offices to monitor the exchange of breathing gases in lung, and the balance of acids and bases in blood. The value of arterial PO2 below 80 mm Hg may indicate improper pulmonary respiration which can be due to increased O2 demand, low inspired O2, or decreased cardiac output. Arterial PCO2 normal range is from 35 to 45 mm Hg. Measured values beyond this range is an indicator of hypocapnia or hypercapnia and tell the health professional about the ventilation status (1).

Biomedical equipment maintenance department in any hospital is responsible for keeping this equipment and others in proper condition to ensure that the device is working properly avoiding long periods of downtime and that the readings measured by the device is accurate and precise and reflect the actual values in patients’ blood sample. In order to achieve this task, planned preventive maintenance according to manufacturer’s recommendations is required at fixed intervals. It is reported that improper performing of inspection and preventive maintenance is responsible for sudden failure of medical devices.

In this paper, the advantages of maintaining blood gas analyzer on a regular schedule and according to the manufacturer recommendations are investigated. Furthermore, the frequent failures of this device during a 4 years period between 2012 and 2016 were analyzed to identify the components of the device that frequently deteriorate.
