Pulmonary Function Test
The test routinely used in patients with chronic respiratory disorders to assess respiratory function and to determine the extent of dysfunction.
What does Pulmonary Function Test measures?
It measurements of lung volumes, ventilatory function, and the mechanics of breathing, diffusion, and gas exchange.
Tool commonly used in Pulmonary Function Test
Spirometer
Arterial Blood Gas
Respiratory diagnostic test that measurements of blood pH and of arterial oxygen and carbon dioxide tensions.
Diagnostic test which is obtained through an arterial puncture at the radial, brachila or femoral artery or through an indwelling arterial catheter
Arterial Blood Gas
It is a noninvasive method of continuously monitoring the oxygen saturation of hemoglobin (SaO2).
Pulse Oximetry
The normal Sp02 values
95% to 100%
Implication of 85% Sp02
It means tissues are not receiving enough oxygen
Sputum Studies
It is is obtained for analysis to identify pathogenic organisms and to determine whether malignant cells are present.
Methods in collecting sputum specimens
Endotracheal aspiration
Bronchoscopic removal
Bronchial brushing
Transtracheal aspiration
Gastric aspiration
Different types of Imaging StudiesChest X-ray Computed Tomography/CT Scan Magnetic Resonance Imaging Flouroscopic Studies Pulmonary AngiographyImaging Studies usually taken after full inspiration (a deep breath) because the lungs are best visualized when they are well aerated.Chest X-rayIt shows major contrast between body densities such as bone, soft tissuee and airChest X-rayImaging study that distinguish fine tissue densityComputed Tomography/CT ScanAn imaging method in which the lungs are scanned in successive layers by a narrow-beam x-ray.Computed Tomography/CT ScanDifference between CT Scan and MRI in terms of machine usedMagnetic fields and radiofrequency signals are used while CT Scan used a narrow- beam xray.Flouroscopic StudiesIt also may be used to study the movement of the chest wall, mediastinum, heart, and diaphragm; to detect diaphragm paralysis; and to locate lung masses.Imaging study that is used to assist with invasive procedures, such as a chest needle biopsy or transbronchial biopsy, that are performed to identify lesions.Flouroscopic StudiesImaging study most commonly used to investigate thromboembolic disease of the lungs, such as pulmonary emboli, and congenital abnormalities of the pulmonary vascular tree.Pulmonary AngiographyDifferent types of Endoscopic ProceduresBronchoscopy ThoracoscopyIt is a direct inspection and examination of the larynx, trachea, and bronchi through either a flexible fiberoptic bronchoscope or a rigid bronchoscopeBronchoscopyA diagnostic procedure in which the pleural cavity is examined with an endoscopeThoracoscopy
