Pulmonary Function Tests

434
Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...

Physical Assessment of the Respiratory Tract II: Palpation01:24

Physical Assessment of the Respiratory Tract II: Palpation

593
Physical assessment of the respiratory tract is critical in identifying potential health issues. One key component of this assessment is palpation, a technique healthcare providers use to assess the body for abnormalities. This content explores the method of palpation in evaluating the respiratory tract, focusing on thoracic palpation and tactile fremitus.
Thoracic Palpation
Thoracic palpation detects tenderness, masses, lesions, respiratory excursions, and vocal fremitus. The nurse assesses...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

44
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Physical Assessment of the Respiratory Tract II: Inspection

407
Physical assessment of the respiratory tract through inspection is a crucial step in understanding the patient's respiratory health. It provides insights into the functioning of the respiratory system, the musculoskeletal structure, and even the patient's nutritional status. This comprehensive approach involves observing several vital aspects: chest configuration, breathing patterns, respiratory rates, skin color, and use of accessory muscles.

Chest Physiotherapy01:24

Chest Physiotherapy

706
Chest Physiotherapy (CPT) is a therapeutic technique used in respiratory care to improve ventilation, clear bronchial secretions, and enhance the efficiency of respiratory muscles. This therapy includes three primary procedures: postural drainage, percussion, and vibration. It can be performed on spontaneously breathing patients and those who are intubated and mechanically ventilated.
Purpose
CPT is primarily used for patients with excessive bronchial secretions who have difficulty clearing...
