Airstream Mechanism

Oxygen is drawn into the lungs by a process called inhalation, (breathing in), which occurs when the diaphragm and intercostal muscles are contracted which causes the lungs to expand, giving a larger volume and therefore causing a lower pressure differential between the lungs, alveolar pressure, and the outside atmosphere. This inverse relationship between volume and pressure is called Boyle’s law. (Tortora & Derrickson, 2011)

By opening the victim?s airway, you are lifting the tongue from the back of the throat which could be the one thing obstructing the airway.

A long drawn and deep inhalation followed by a complete closure of the glottis, which results in a strong exhalation that suddenly pushes the glottis open and sends a blast of air through the upper respiratory passages. Stimulus for this

B. What is the cough reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing?

➢ After leaving the pharynx, air enters the ;larynx, where two pairs of ligaments, together with the mucosa covering them, forms the vestibular and vocal folds. These folds help prevent foreign particles, including food, from entering the lower respiratory system.

Lungs: Diminished breath sounds in all lung fields. Resonant to percussion. No wheezes, rales, or rhonchi. Symmetric chest expansion. Breathing nonlabored.

Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. In the chest cavity, the trachea splits into two smaller tubes called the bronchi. Each bronchus then divides

Lungs: Diminished breath sounds in all lung fields. Resonant to percussion. No wheezes, rales, or rhonchi. Symmetric chest expansion. Breathing nonlabored.

Lungs: Clear to auscultation bilaterally. No wheezes, rales, or rhonchi. Symmetric chest expansion. Breathing nonlabored. Diminished breath sounds in all lung fields. Resonant to percussion.

in children it is often accompanied by a ‘whoop’ sound as the individual tries to inhale.

Air can be breathed in through both the nose and the naval cavity, or the mouth, also known as the oral cavity. The air, regardless of the path taken, will always lead to the pharynx, a space located at the back of throat. It will progress through the larynx,

Vocal fold paralysis is diagnosed by an otolaryngologist through the use of endoscopy, laryngostroboscopy, and laryngeal electromyography. Two types of endoscopes may be used to visualize the vocal folds. One type is a rigid endoscope that is placed in the back of the oral cavity with a camera pointing down

The respiratory system is the process responsible for the transportation and exchange of gases into and out of the human body. As we breath in, oxygen in the air containing oxygen is drawn into the lungs through a series of air pipes known as the airway and into the lungs. As air is drawn into the lungs and waste gas excreted, it passes through the airway, first through the mouth or nose and through the pharynx, larynx and windpipe – also known as the trachea. At this point it then enters the lungs through the bronchi before finally reaching the air sacs known as alveoli. Within the lungs, through a process known as diffusion, the oxygen is transferred to the blood stream through the alveoli (air ducts) where it is then transported inside

Respiratory: Lung sounds are clear on auscultation without rales, rhonchi, or wheezes. Respiration unlabored with

This means that air does not pass through the vocal cords and so speech is not possible. Sometimes patients can have a tracheostomy tube that allows some air to go through the vocal chords and out of the mouth. Patients can have this type of tube if they are able to swallow without difficulty and if they do not need a tracheostomy tube with an inflated cuff in order to get air into the lungs.
