Brief summary

Some people who are unwell in hospital need to be given oxygen. This is done to improve blood oxygen levels and is usually given through a mask or small prongs which sit inside the nostrils. Research studies have shown that it is very important to give the correct amount oxygen. Blood oxygen levels which are either too high or too low can be harmful. Depending on the particular illness, there is a recommended ‘target range’ for blood oxygen levels. At the moment, doctors and nurses intermittently turn the amount of oxygen up or down to try and get a patient’s blood oxygen levels in the ‘target range’. This can be difficult to get right because the amount of oxygen a patient needs will change over time. This purpose of this study is to continuously measure blood oxygen levels using a finger sensor for 24 hours. This will help us find out how much time patients spend with blood oxygen levels in the ‘target range’. This is important to know to help improve the way oxygen is given in hospital.

Interventions

In this observational study, patients who have been admitted to Wellington Regional Hospital and Hutt Hospital for an acute illness who are receiving oxygen therapy will be recruited. Patients will be required to have a target peripheral oxygen saturation (SpO2) range prescribed to be included in the study. Enrolled participants will have SpO2 measured continuously for 24 hours using a pulse oximeter. The pulse oximeter display will be hidden from clinical staff and alarms will be turned off in

In this observational study, patients who have been admitted to Wellington Regional Hospital and Hutt Hospital for an acute illness who are receiving oxygen therapy will be recruited. Patients will be required to have a target peripheral oxygen saturation (SpO2) range prescribed to be included in the study. Enrolled participants will have SpO2 measured continuously for 24 hours using a pulse oximeter. The pulse oximeter display will be hidden from clinical staff and alarms will be turned off in order to avoid influencing clinical management. All other clinical care including oxygen titration will be performed as per routine practice. There are no interventions as part of this study. The participant's involvement in the study will end after the 24 hour monitoring period.
