Isolated patients

blood gas analyser for isolated patientsThe need to keep patients isolated due to contagious infection or a compromised immune system can add significant workload into the intensive care unit. Strict protocols aim to stop contact or airborne transmission of pathogens.

However, patients in isolation rooms have been found to be at significantly increased risk for ventilator-associated pneumonia, anticoagulant administration or prescription errors, hyperglycaemia and hypoglycaemia when compared with non-isolated ones [1].

Measurement of blood samples remains a weakness in isolation of the patient. Potentially infectious samples are transported out of the isolation room for measurement in a centralised blood gas analyser, increasing the risk of contact transmission. Often a spare staff member is required to pass the sample out for analysis, potentially delaying the time to result if they are not available. Alternatively, the carer needs to de-gown before leaving the isolation room and then re-gown to return to the patient.  

The Proxima system is designed to offer real infection prevention and control benefits to patients in ICU by maintaining isolation and reducing blood handling. Blood samples are measured directly at the patient’s bedside without the need to transport potentially infectious blood outside the isolation room and reducing the number of times that the isolation barrier is broken.
