# Contraindications to PFT The following are contraindications to Pulmonary Function Tests (PFTs): * **Patients with acute, unstable cardiopulmonary problems:** This includes conditions like hemoptysis, pneumothorax, myocardial infarction, pulmonary embolism, and acute chest or abdominal pain. * **Patients who have nausea and are vomiting:** These patients have a risk of aspiration. * **Patients who have had recent cataract removal surgery:** Testing these patients should be delayed. * **Patients with dementia or confusion:** These types of patients may not be able to cooperate or follow instructions, making optimal or repeatable test results difficult. * **Patients who are acutely ill or have recently smoked:** In these cases, the validity of measuring Forced Vital Capacity (FVC) may be hindered. Patients must follow instructions for the test and demonstrate cooperation.
