Flashcards in Respiratory Exam 1 Deck (87)
The presence of air or gas in the pleural space that cause lung collapse.
The accumulation of blood in the pleural space.
A buildup of fluid between the tissues that line the lungs and the chest.
Decreased o2 in the tissues
decreased 02 in the blood
partial airway obstruction
In partial airway obstruction the patient will be able to breathe and cough, although there may be a 'crowing' noise (stridor) as air passes through a narrowed space.
Condition in which fluid collects in the lungs' air sacs, depriving organs of oxygen.
Normal range of adult VS plus SA02 range
Sa02 95% - 100%
a dome-shaped muscle separating the thoracic and abdominal cavities. It contracts and flattens to increase both the chest (pleural) space and the pleural vacuum
part of the pharynx extending from the uvula to the epiglottis
The walls of the alveoli are composed of a single layer of cells and are lined with a chemical called surfactant, which helps to prevent the alveolar walls from collapsing between breaths.
pleura in lungs
The lower respiratory tract contains a smooth double-layered sac of serous membrane called
The mucosa, or mucous membrane, is a type of tissue that lines the nasal cavity. Mucous membranes are usually moist tissues that are bathed by secretions such as in the nose.
From the pharynx, air passes into the larynx, a box-like structure made of cartilages held together by ligaments.
Air travels from the nose to the pharynx, a tube-shaped passage for air and food.
A lid or cover of cartilage called the epiglottis (“trap door cartilage”) guards the entrance to the larynx.
It is a passageway for air only.
medulla and pons
Normal breathing occurs as a result of nervous stimulation of the respiratory center in the brain’s medulla. The medulla sends impulses to the diaphragm and the intercostal muscles.
The pons has centers that work with the medulla to produce a normal breathing rhythm.
Name the protective reflexes of the respiratory system.
trace the flow of air you breathe once it goes through the nose and mouth
through nose and nostrils. nasal cavity where air is warmed and moistened. hairs and sticky mucous trap particles. clean air entered trachea. trachea branches to to bronchi. branches to bronchioles. these end in air sacs called alveoli. surrounded by capillaries. enters blood stream.
the purpose of chest suction is to restore the negative pressure where and how
the depth of the water in the suction bottle determines the amount of negative pressure that can transmitted to the chest.
describe what exactly "aerosol therapy" is about
aerosol therapy use of an aerosol for respiratory care in the treatment of bronchopulmonary disease. The major purpose of this is the delivery of medications or humidity or both to the mucosa of the respiratory tract and pulmonary alveoli. Agents delivered by aerosol therapy may act in a number of ways: (1) to relieve spasm of the bronchial muscles and reduce edema of the mucous membranes, (2) to render bronchial secretions more liquid so that they are more easily removed, (3) to humidify the respiratory tract, and (4) to administer antibiotics locally by depositing them in the respiratory tract
what equipment would you need to do aerosol therapy
a metered dose inhaler
nebulizer. tubing, mask, medication
why is the purpose of having serous fluid between the lungs pleural membranes
The main function of pleural membranes is to hold the two lungs within their pleural cavity. These membranes do this while ensuring that the lungs remain expanded during out-breaths and can move along each other smoothly during the process of breathing.
when teaching patients about their oxygen use why do we need to stress the importance not smoking, candle use, ungrounded electrial
Oxygen tanks are extremely dangerous in a sense that it can combust
no smoking, no wool hoodies.
what is the use of accessory muscles indicate
in labored breathing, the use of muscles other than the diaphragm and intercostals. the sternocleidomastoid, spinal, neck, and abdominal muscles and even the platysma, may be used. their use is a sign of an abnormal or labored breathing pattern.
what exactly does the pulse oximetry tell us? how does it work?
it tells us the amount of oxygen circulating in the blood. It's a red light
what do ABG's tell us
An arterial blood gas (ABG) test measures the acidity (pH) and the levels of oxygen and carbon dioxide in the blood from an artery
