Martha Lozano, MD, a triple-board-certified pulmonologist in Chula Vista's Eastlake corridor, holds certifications in pulmonary disease (1990), critical care medicine (1991), and internal medicine (1987) from the American Board of Internal Medicine. Her ICU-level critical care privileges at Sharp Chula Vista Medical Center on Medical Center Drive support ventilator management and acute respiratory failure interventions for patients admitted through the hospital's emergency department. She earned her medical degree from the Universidad Autonoma de Nuevo Leon and completed her internship, residency, and pulmonary/critical care fellowship at Baylor University Hospital. Her Kuhn Drive office in the 91914 zip code serves the Eastlake and Rolling Hills Ranch communities with pulmonary function testing for COPD, asthma management, and interstitial lung disease evaluation. CPAP titration and home-ventilator prescription for obstructive sleep apnea patients require ongoing pharmaceutical coordination with dispensaries that stock respiratory-specific medications, including Sunrise Pharmacy for nebulizer solution and inhaler refills. Highest-complexity services include bronchoscopy with bronchoalveolar lavage for pulmonary infiltrate diagnosis and mechanical ventilation weaning protocols in the intensive care unit.
