Resp. & O2 ch 85/86

Respiratory and Oxygen Therapy

functions of the respiratory system O2/CO2 exchange, acid-base balance, protection, speech production
upper respiratory tract nose, sinuses, pharynx, trachea
lower respiratory tract bronchi, lungs
where O2 is exchanged for CO2 within the lungs alveoli
food/air goes through what to get to the esophagus pharynx
exchange of gases between the environment and the body's internal cells respirations
respiratory refleses coughing, sneezing yawning
ventilation means breathing
what part of our brain stimulates respirations medulla
what assists the medulla in maintaining respirations diaphragm and intercostal muscles
major regulator of respirations carbon dioxide
what makes it where you have some voluntary control of your breathing cerebral cortex
respirations that are at the lung level external
respirations that are at the cellular level internal
collect sputum specimen when? first thing in morning
specimen where MD goes through nose to get it lavage specimen
<7 acidosis
>7 alkalosis
test that measures lung capacity PFT (pulmonary function test)
puncturing the chest wall to remove excess fluid or air from the pleural cavity is called thoracentesis
uses position and gravity to drain secretions and mucus from the individual's lungs postural drainage
puncturing of the abdominal cavity for aspiration of fluid paracentesis
an incision into the thorax r chest cavity thoracotomy
do this w/postural drainage CPT (chest percussion therapy)
normal breathing eupnea
common cold rhinitis
rhinitis is spread by droplets
loss of the sense of smell is common in what respiratory disorder tracheotomy
puss in pleural space empyema
non-productive cough is common in what respiratory disorder bronchitis
alveoli collapses in what respiratory disorder atelectasis
abnormal, permanent enlargement of the alveoli and alveolar ducts w/destruction of the alveolar walls pulmonary emphysema
alveoli quit working and the x-ray is complete white ARDS (acute respiratory distress syndrome)
spread by inhalation of droplets and verified by chest x-ray TB (pulmonary tuberculosis)
if poorly managed, can lead to emphysema asthma
more than 5 cessations of airflow for at least 10 seconds each per hour of sleep sleep apnea
an attack that persists for more than 24 hrs. and that does not respond to treatment is called status asthmaticus
how fast a person can exhale after deep inhalation peak flow
1st action c/pt. experiencing sob reposition pt. into an orthopneic position
priority intervention if Pleur-Evac system becomes disconnected from chest tube double-clamp the chest tube
option that indicates the pt. is experiencing severe hypoxemia hypotension
relates most directly to a dianosis of pulmonary emphysema decreased breath sounds, barrel chest, sob
the nurse suspects pleurisy when the client complains of chest pain w/inspiratin plus complaint of an earache
primary risk factor for developing lung cancer exposure to smoke or smoking cigarettes
low-flow device that uses a bag instead of valves PRM (partial-rebreathing mask)
uses valves on the outside of the mask as well as between the mask and bag NRM (non-rebreathing mask)
too much oxygen can lead to respiratory arrest
offers specific oxygen concentrations ranging from 24 to 50% that match specific adapters for flow rates of 4,6, or 8 lpm venturi masks
this ventilator encloses all or part of the body negative pressure ventilator
oxygen sources available for home use oxygen cylinders and concentrators
these ventilators can deliver a consistent volume of air with each breath, a preset pressure of air or total breathing for the client at set intervals positive pressure ventilators
type of ventilation where the pt. takes on more work of breathing and gradually progresses to breathing w/o mechanical assistance SIMV (synchronized intermittent mandatory ventilation)
Oxygen by mask must be at a minimum flow rate of 6 lpm
respiratory doctor pulmonologist
sore throat pharyngitis
top of lung apex
hair-like projections cilia
inflammation of the pleura pleurisy
measures amount of oxygen in the blood pulse-oximeter
double layered sac of serous membranes pleura
reduces surface tension in the lungs surfactant
barking like a seal stridor
bottom of lung base
nose bleed epistaxis
easing pain on surgical incision site splinting
blood in lung cavity hemathorax
common breath sound heard in asthmatics wheezing
during pulmonary perfusion 02 binds to blood
