Background:
Oxygen is commonly used in the acute care setting. However, used inappropriately, oxygen therapy can result in adverse consequences, including progressive respiratory failure and death.
Aim:
To investigate the effectiveness of a targeted intervention to improve prescribing practice and therapeutic application of supplemental oxygen.
Methods:
Respiratory, Oncology and Surgery wards were targeted for the intervention. Nursing and junior medical staff from these wards undertook an education programme about safe use of oxygen. Cross-sectional data about oxygen prescribing, administration and monitoring were collected on inpatients in these wards at baseline, and at 3 and 6 months post-intervention, using a modified version of the British Thoracic Society Oxygen Audit Tool.
Results:
At baseline, there was a written prescription for oxygen in 56% of patients (n = 43) using oxygen and this increased to 75% (n = 44) at 3 months, and remained at 65% (n = 48) at 6 months. However, the increased prescription rates were not statistically significant when compared to baseline (χ2 = 3.54, df = 1, P = 0.06 and χ2 = 0.73, df = 1, P = 0.40, respectively). The observed increase in oxygen prescriptions was driven by the medical wards: Oncology ward at 3 months (χ2 = 8.24, df = 1, P = 0.004); and Respiratory ward at 3 months (χ2 = 3.31, df = 1, P = 0.069) and 6 months (χ2 = 4.98, df = 1, P = 0.026).
Conclusion:
The education programme intervention to improve oxygen prescription showed promise in the medical wards but did not impact outcomes in the surgical ward setting, where different strategies may be needed.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
01:23Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
