Breathing01:05

Breathing

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...
Alterations in Respiration II01:30

Alterations in Respiration II

There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...

Physical Assessment of the Respiratory Tract II: Inspection

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 Configuration
The chest configuration can...
Other Factors Affecting Respiration Centers01:17

Other Factors Affecting Respiration Centers

Breathing is primarily an involuntary activity regulated by the brainstem respiratory centers. However, it can also be consciously controlled, allowing us to hold our breath or take deeper breaths when needed. This voluntary control is facilitated by the cerebral motor cortex, which bypasses the medullary centers to stimulate the respiratory muscles directly.
However, the ability to hold one's breath voluntarily is not limitless. When the CO2 concentration in the blood reaches a critical level,...
Assessment of Ventilation II: Respiratory Depth and Rhythm01:29

Assessment of Ventilation II: Respiratory Depth and Rhythm

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
Mechanism of Breathing III: The Accessory Muscles01:21

Mechanism of Breathing III: The Accessory Muscles

The Role of Accessory Muscles in the Respiratory System
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Patient Care

Background:

  • Nasal packing is standard after septal, rhinoplasty, or endoscopic sinus surgery to control bleeding.
  • Traditional nasal packs impede nasal breathing, causing significant post-operative discomfort and sleep disturbance.

Purpose of the Study:

  • To introduce a novel technique for nasal packing that facilitates improved nasal airflow.
  • To enhance patient comfort and sleep quality during the initial post-operative period.

Main Methods:

  • A technique involving trimmed straws integrated with Netcell packs for nasal packing is described.
  • This method is applied in post-operative care for septal surgery, rhinoplasty, and endoscopic sinus surgery.

Main Results:

  • The modified nasal packs allow patients to breathe more easily through their nose.
  • The technique also provides effective suction of blood and mucous from the post-nasal space.

Conclusions:

  • This innovative nasal packing method offers a practical solution to improve post-operative breathing.
  • It enhances patient comfort and sleep while maintaining effective haemostasis and drainage.
