MANGALURU: Health experts have recommended deploying pulse oximeters and chest X-rays to identify potential Covid-19 patients early in suspected clusters across Dakshina Kannada district. The suggestion comes amid growing concern over possible community transmission in several pockets.

Dr Farhan Fazal, infectious disease specialist at KMC Mangaluru, explained that while these tools cannot catch every early case, they effectively detect deterioration. "Many patients do not feel breathless constantly but can develop hypoxia. Pulse oximeter and chest X-ray will come handy in such cases," he said, noting they add value to detection without being the final word.

Dr P Kamath, a cardiologist, cited instances where patients showing Ground Glass Opacities (GGO) on chest X-rays later tested positive for Covid-19. Though not universal, he argued the method aids early identification and deserves trial in cluster areas.

Sources indicate that some doctors have urged Deputy Commissioner Sindhu B Rupesh to consider door-to-door pulse oximeter checks using ASHA workers in localities such as Thokkottu, Ullal, Bantwal, Kadaba, and Suratkal. Individuals with low oxygen saturation would then undergo chest X-rays followed by swab tests. This approach prioritizes potential critical patients and eases ventilator demand in hospitals.

Dr Kamath pointed to rising cases with no travel history as clear signs of community transmission. "You need to identify and isolate them early before symptoms develop. Providing oxygen to those with low saturation can prevent lung damage. Chest X-rays then reveal whether the virus has affected the lungs," he said, calling the method useful in most cases.
