South Bay Pulmonary Medical Group in Chula Vista's eastern corridor occupies Kuhn Drive, where the practice has operated since 1980 under FCCP-designated pulmonologist Jose A. Lira, MD, who holds board certifications in both pulmonary disease and internal medicine. Respiratory emergencies including acute exacerbations of COPD and pneumonia-related hypoxia often route through triage at nearby walk-in clinics such as Perlman Clinic Chula Vista before escalating to the group's pulmonary-function testing and bronchoscopy services. The practice also directs the Eastlake Sleep Center, founded in 2005, which conducts overnight polysomnography studies for obstructive sleep apnea diagnosis and CPAP titration in a dedicated facility. Referrals to the group flow primarily from the network of Sharp-affiliated primary-care providers across the Otay Ranch zone, including physicians at Jorge A. Mota, MD - Sharp Rees-Stealy Otay Ranch, establishing a coordinated care pipeline for chronic lung disease management. The highest-acuity services include flexible fiberoptic bronchoscopy with bronchoalveolar lavage for interstitial lung disease evaluation and spirometry-guided medication titration for severe persistent asthma.
