Respiratory Assessment + Trach Flashcards
What are some health promotion and maintenance factors?
— assess smoking habits
— promote smoking cessation
*pack years = # of years smoked ❎ packs smoked
— determine exposure to other inhalation irritants
— protect the respiratory system
What are changes in the respiratory system related to aging?
Alveoli
— airways close early
— elastic recoil decreases
— diffusion capacity decreases
Lungs
— vital capacity decreases
— impaired gas exchange
— decreased elasticity
Pharynx and larynx
— muscle atrophy
— lose elasticity
— airways lose cartilage
Susceptibility to infection
Mobility of chest wall decreases
Exercise intolerance
Muscle strength decreases
Risk for hypoxia increases
What do you assess with skin and mucous membranes?
Assess the nail beds and mucous membranes of the oral cavity
Examine fingernails for clubbing (indicates long term hypoxia)
What do you assess with the general appearance?
— long term respiratory problems lead to weight loss and loss of muscle mass
— arms and legs appear thin or poorly muscled
— neck and chest muscles may be hypertrophied
What do you assess with endurance?
— decreases whenever gas exchange is inadequate
— observe how easily rage patient moves and whether the SOB is at rest or upon exertion
— note how often patient pauses for breath between words when talking
What is apart of the psychological assessment?
— SOB often induces anxiety and anxiety can make shortness of air even worse
— stress may worsen some respiratory problems
— discuss coping mechanisms
— chronic respiratory disease: changes in relationships, social isolation, financial problems/unemployment, disability
— assist the patient to identify available support systems
What does RBC labs tell you?
Data about the transport of oxygen
*normal range = M: 4.0-5.9, F: 3.8-5.2
RBC count decreases with age
What does hemoglobin do?
Transports oxygen to the tissues
*deficiency could cause hypoxemia
What does WBC tell you?
Indication of infection
Common labs and imaging assessments:
Sputum culture, chest x-ray, chest CT
What does pulse oximetry indicate?
Identifies hemoglobin saturated with oxygen
Normal: 95%-100%
*below 91% requires immediate assessment and treatment
What does a pulse oximetry of 85% tell you?
Body tissues have a difficult time becoming oxygenated
What is capnometry and capnography testing?
How quickly and how often someone exhales
What is a laryngoscopy and what does it do?
Scope inserted into larynx to assess the function of the vocal cords
— used to remove foreign bodies caught in the larynx
— obtains tissue samples for biopsy or culture
*patients receive sedation
What is a mediastinoscopy and what are the uses?
Insertion of a flexible tube through the chest wall just above the sternum into the area between the lungs
— examine for tumors
— obtain tissue samples for biopsy or culure
*performed under general anesthesia
