PHTY205 Lecture Notes - Lecture 17: Human Respiratory Syncytial Virus, Pneumocystis Jirovecii, Pulmonary Function Testing
Document Summary
Describe the complete clinical reasoning process: patient signs and symptoms, history taking, observation and palpation, auscultation, spirometry, cxr. Interpret investigations: thoracic imaging cxr, ct, mri, ctpa, pulmonary function testing, respiratory muscle strength, arterial blood gases, blood tests. Identifies pathological organisms in sputum in order to direct appropriate therapy: atypical organisms can be identified e. g. fungi, tuberculosis (tb) 3 consecutive samples to be negative for acid fast bacilli. Respiratory syncytial virus (rsv), or bordetella pertussis (whooping cough: bronchoscopy. Invasive test done under general anaesthetic or sedation: bronchoscope is passed down the trachea into the large airways, diagnosis to visualise airway anatomy looking for airway inflammation, malignancy or sputum retention. Fine needle biopsy: therapeutic: bronchoscopic alveolar lavage (bal) Lung wash out: exercise testing, 6mwt, cardiopulmonary exercise test (vo2 max) Interpret other investigations/information: cardiac: 12 lead ecg, myocardial perfusions scans, exercise stress testing, neurological: eeg, nerve conduction testing, icp.
