O2 Objectives Flashcards
1st symptom you may notice in hypoventilation
change in mental status
2 prongs inserted into nostril
Does not interfere with eating or speaking
Easy home use
Disadvantages
Delivers up to 6 LPM
Nasal Cannula
A diuretic is
substance that promotes diuresis, the increased production of urine
A series of tests to detect lung volume and capacity.
Pulmonary function studies
ABG means and evaluates
Arterial Blood Gases
effectiveness of gas exchange.
Accumulation of fluid and blood in the pleural space interferes with lung expansion, ventilation, and gas exchange.
Hemothorax
Air in the pleural space creates positive pressure, causing lung collapse
pneumothorax
Allows mask to deliver the most precise concentrations of O2
Venturi Mask
Alveoli that have been overstretched, as with_______ , lose their elastic recoil over time. This loss of elasticity allows the lungs to ______ easily but inhibits deflation, leaving stale air trapped in the ________
emphysema
inflate
alveoli.
Bronchodilators are contraindicated for
clients when stimulation of the sympathetic nervous system would be dangerous – cardiac disease, vascular disease, diabetes, hyperthyroidism, etc.
Bronchoscopy Need: NPO for Assess for: Remove: NPO until: NO
informed consent 6-8 hrs prior allergies to iodine (in case of contrast) dentures gag reflex returns
No smoking, talking or coughing for several hours
Capnography measures and should be
co2 (expiratory / end tidal) 35-45
Chest xray
better if person is
standing up
Clients with ____________ become insensitive to CO2 and respond to hypoxia (low O2) levels to stimulate breathing
So . . . if __________ is given and the blood oxygen level is raised, the stimulus to breathe is _____________
COPD (emphysema)
excessive oxygen
removed
collapse of alveoli
atelectasis
Deep breathing and coughing is essential to prevent
pneumonia
Delivers highest concentration of O2 via a mask to a client who is breathing on their own
Non-Rebreather Mask
Diagnosis :inability to maintain a clear airway
Ineffective Airway Clearance
Diagnosis :used to describe inadequate ventilation, such as hypoventilation, hyperventilation, tachypnea, or bradypnea.
Ineffective Breathing Pattern
Diagnosis:appropriate diagnosis if the patient is ventilating adequately but diffusion of gases across the alveolar-capillary membrane is impaired.
Impaired Gas Exchange
Diagnosis:describes a condition in which a patient, as a result of decreased energy reserves, is unable to maintain breathing adequate to support life.
Impaired Spontaneous Ventilation
Diagnosis:should be used when there is a risk for secretions, solids, or fluids entering into tracheobronchial passages (e.g., for patients who have had head or neck surgery or who have a reduced level of consciousness).
Risk for Aspiration
drug delivery device used to administer medication in the form of a mist inhaled into the lungs.
Nebulizers
Face mask with reservoir bag
What does the bag do?
Flow rate:
O2 delivery
partial rebreather
collects first part of exhaled air - rebreathes expired air
8-11
40-70%
