Abstract
Background: Patients with valvular heart diseases may have more physiological lung derangements. We studied correlation of O2 challenge, A-AG tests and spirometry values of patients who underwent valve surgery. Method: 180 patients undergoing cardiac valvular surgery were studied. On operating room all patients had arterial blood gas profile at room air, 20 minutes after putting on ventilator with 100% O2, and pump oxygenator. Pulmonary function tests, alveolar Oxygen Pressure, mean Arterial pressure of carbon dioxide and alveolar- arterial gradients measured. Results: FEV1, FVC and FEV1/FVC%, pressure of arterial Blood Gasses (O2 and CO2) with fraction of inspired oxygen of 100% were significantly different in patients with POPC (p-value Conclusion: There is significant correlation between A-AG100, A-AG21 percent, PaO2100, and FEV1/FVC with post op complications in these patients. We recommend measurement of these values in pre op evaluation of patient who need cardiac surgery.
