Summary
Coughing protects lung function and airway patency through reflex stimulation and voluntary effort. This vital mechanism involves sensitive areas in the upper airway down to the main bronchi divisions.
Area of Science:
- Pulmonology and Respiratory Physiology
Background:
- Coughing is a crucial protective reflex for maintaining lung function.
- Airway patency is essential for unobstructed breathing and is supported by ciliary action and coughing.
Purpose of the Study:
- To describe the physiological mechanisms and anatomical locations involved in the cough reflex.
- To differentiate between reflex-induced and voluntary coughing.
Main Methods:
- Review of established physiological principles of respiratory reflexes.
- Anatomical localization of cough-sensitive areas within the respiratory tract.
Main Results:
- The cough reflex is initiated by stimulation of specific sensitive areas in the upper airway, extending down to the main bronchi.
- Coughing contributes to maintaining airway patency alongside normal ciliary function.
- Conscious, voluntary effort can also initiate coughing.
Conclusions:
- Coughing is a multifaceted protective mechanism essential for respiratory health.
- Understanding the cough reflex pathway is key to managing respiratory conditions.

01:27Pneumothorax-II
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

01:20Sputum Studies II: Culture and Sensitivity
Description
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...

01:26Endoscopic Studies II: Thoracocentesis
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
