Respiratory Basics
The process of moving air in and out of the lungs
What is respiration?
These muscles support breathing by moving the ribs up and down
What is the Intercostal muscles?
This assesses the amount of air an individual is able to inhale and exhale
What is Pulmonary function testing (PFT)?
One full inhalation and one full exhalation
What is the respiratory cycle?
This contains the vocal folds
What is the larynx?
The volume of air inhaled and exhaled during a full cycle of respiration
What is tidal volume?
What is the thoracic cavity?
Strengthening the respiratory muscles can help improve endurance for this
What is breathing?
The primary muscles involved are the external intercostal muscles and the diaphragm
What is inspiration?
This muscle contracts and flattens to increase lung volume for inhalation before speech
What is the Diaphragm?
The total amount of air the lungs can hold
Provide the formula
What is Total Lung Capacity (TLC)?
What is TV + IRV + ERV + RV?
This nerve tells the diaphragm when to contract
What is the Phrenic nerve?
These muscles are important for controlling airflow during speech
What is abdominal muscles?
__ takes up 40 percent of the cycle, while __ takes up 60 percent of the cycle
What is Inhalation and Exhalation?
This is often referred to as the bronchial tree
What is the trachea, bronchi, and bronchioles?
The extra amount of air that can be forcibly inhaled after a normal inspiration
What is Inspiratory Reserve Volume (IRV)?
This forms the front of the ribcage and is commonly known as the breastbone
What is the Sternum?
These are used in therapy to help patients with various respiratory disorders improve their lung function
What is spirometers?
When expanded during inspiration, greater recoil forces are generated
What is the thoracic cavity and lungs?
These muscles helps regulate airflow for speech
What is Intercostal muscles?
The extra amount of air that can be forcibly exhaled after a normal exhalation
What is Expiratory Reserve Volume (ERV)?
The angle of these can change with upright posture
What is the Ribs?
A therapy approach that strengthens inspiratory and expiratory muscles
What is Respiratory Muscle Training (RMT)?
Depending on if this is negative or positive, air from the atmosphere is either forced into or out of the respiratory system
What is P alv?
The combination of tidal volume, inspiratory reserve volume, and expiratory reserve volume (TV + IRV + ERV)
What is Vital Capacity (VC)?
