Oxygenation Flashcards
Inspriation
Air flows into the lungs
Expiration
Air flows out of the lungs
Cheyne-Stokes Respirations
Increased and Decreased rate and depth of ventilation followed by apnea lasting 20-60 seconds
Kussmaul Respirations
Deep, Grasping, Rapid breathing
Biot’s Respirations
Rapid, Deep respirations with abrupt pauses between each breath
Obstructive Breathing Pattern
Inhale & Exhale Ratio of 1:4 or Greater
Apnea
Stopping breathing for more than 15 seconds
Orthopnea
Difficulty breathing while lying down
Dyspnea
Difficulty breathing, with:
~ Shortness of Breath
~Nostril Flaring
~ Increased Heart Rate
Dyspnea stems from what?
A cardiac or respiratory problem
What is the definition of Hypoxia?
Reduced Oxygen Level in the Blood
What does the body do to compensate for Hypoxia?
Increases Heart Rate and Increased Cardiac Output
What causes Hypoxia?
Conditions that Impair Alveolar-Capillary Diffusion (e.g. Pulmonary Edema)
What are the symptoms of Hypoxemia?
~ Rapid Pulse ~ Cyanosis ~ Substernal or Intercostal retractions ~ Rapid, shallow respirations ~Dyspnea ~ Flaring of the nares ~ Increased restlessness or lightheadedness
Condition of insufficient oxygen in body tissue; results from unresolved hypoxemia
Hypoxemia
Nursing Interventions to Promote Oxygenation
Position the client for maximum chest expansion (semi or high Fowler’s)
Encourage or provide for frequent position changes
Encourage Deep breathing and coughing
Implement Comfort Measures
How to promote Oxygen Therapy through Nursing interventions
Check Vital Signs and Oxygen Saturation Level
Ordered for clients with hypoxemia, anemia, and blood loss
Nurse may implement oxygenation in an emergency, then call provider
Tracheostomy
It is an opening in the trachea. The patient cannot speak
It has an outer and inner canula, obturatory, and a flange with tubes or ties
Contains an airtight seal, which prevents aspiration and air leakage
What does nursing care for a Tracheostomy involve?
Cleaning and Suctioning
What does Suctioning with A Tracheostomy do?
Aspirates secretions through a catheter that is connected to a suction machine or a wall section outlet
During Trach Suctioning, what should the nurse do?
Assess for respiratory distress
How would you decrease the complications of Trach Suctioning??
Hyperinflation
Hyperoxygention
Hyperventilation
Gently Rotate catheter, withdraw while suctioning. Suction for 5-10 seconds
What are the possible complications of Trach Suctioning that the Nurse should be aware of?
Hypoxemia
Trauma to the airways
Nosocomial Infection
Cardiac Dysrhythmia
What are the implications for Trach Suctioning???
Client is unable to cough up snd expectorate secretions Dyspnea Poor Skin Color Bubbling or Rattling breath sounds Decreased O2 saturation
Procedure for a Tracheostomy Suctioning and things to keep in mind.
•Assess for adventitious sounds and cough reflex
•Do not delegate to UAP
•Review documentation; note responses if client has been suctioned previously
•Explain procedure and tell client it may cause coughing
•Wash hands
•Place client in semi-Fowler’s if possible
•Resuscitation apparatus attached to O2 adjusted at 100%
•Sterile saline/water in sterile basin; sterile towel over client’s chest
•Suction pressure per agency (usually 80-120 mmHg adults, 60-100 mmHg children)
•Apply PPE and sterile gloves
•Attach catheter (in dominant hand) to suction tubing connector (nondominant hand)
•Flush and lubricate catheter with sterile saline
•Hyperventilate lungs before suctioning
–Exception: If secretions are copious, hyperventilation could push them deeper. Instead, increase oxygen to 100% for a few breaths.
•Insert catheter without applying suctioning 12.5 cm (5 in) into trachea or till client coughs
•Apply suctioning for 5-10 sec (thumb over port) while rotating and withdrawing catheter
•Stop suction
•Hyperventilate client; reassess; repeat suctioning if needed.
–After each suction, ventilate with up to 3 breaths
–Observe respirations, skin color
–Encourage deep breathing, coughing
–2-3 min with O2 if possible between suctions
–Flush catheter and repeat suctioning until airway clear, breathing not labored
•Document
How to provide Tracheostomy Care
•Establish sterile field
•Pour soaking solution and saline into containers
•Apply gloves
•Remove O2 source
•Unlock and remove inner cannula (if present); place in soaking solution (unless disposable)
•Remove soiled trach dressing; dispose of dressing and gloves; apply sterile gloves
•Clean lumen and inner cannula with brush or pipe cleaner; rinse in sterile saline; dry inner surface of cannula only
•Reinsert inner cannula and lock in place
•Clean incision and tube flange with sterile technique
•Apply sterile trach dressing
•Change trach ties or Velcro collar
–2-strip method
–1-strip method
–Velcro collar method
•Remove and discard gloves
•Perform hand hygiene
•Document
How many times do you do incentive spirometry and how often?
Several times and then 4-5 times every hour
Things to remember about suctioning!
•Decrease complications by –Hyperinflation –Hyperoxygenation –Hyperventilation –Gently rotate catheter, withdraw while suctioning, suction for 5-10 seconds
