Oxygenation Flashcards
a clear, odorless gas that constitutes approximately 21% of the air we breathe, is necessary for proper
functioning of living cells.
oxygen
True or False:
Absence of oxygen can lead to cellular, tissue and organ death
True
condition of insufficient oxygen anywhere in the body, from the inspired gas to the tissues
hypoxia
refers to reduced oxygen in the blood
hypoxemia
inadequate alveolar ventilation
hypoventilation
accumulation of carbon dioxide in the blood
hypercapnia
True or False:
To promote oxygenation, deep breathing and coughing may be done
True
True or False:
Avoid episodes of coughing because these may cause fatigue and hypoxemia
True
Also referred to as sustained maximal inspiration devices (SMIs), measures the flow of air inhaled through the mouthpiece
Incentive Spirometry
True or False:
Incentive spirometry can be used to improve pulmonary ventilation and loosen respiratory secretions
True
True or False
The sequence for PVD is usually vibration, percussion, postural drainage, removal of secretions by coughing or suctioning
False - The sequence for PVD is usually postural drainage, percussion, vibration, removal of secretions by coughing or suctioning
A dependent nursing intervention that is used over congested lung areas can mechanically dislodge tenacious secretions from the bronchial walls
Percussion
Used after percussion to increase the turbulence of the exhaled air and thus loosen thick secretions
Vibration
Drainage by the gravity of secretions from various lung segments
Postural Drainage
True or false:
The best times to perform postural drainage include before breakfast. lunch, in the late afternoon and before bedtime
True
Clients who have difficulty ventilating all areas of their lungs. Those whose gas exchange is impaired, or people with heart failure may benefit from this
Oxygen Therapy
True or False:
The oxygen delivery system includes a cannula, face mask, and face tent
True
What are the kinds of face masks for the oxygen delivery system?
Simple face mask
Partial rebreather mask
Non-rebreather mask
Venturi mask
This may replace masks when masks are poorly tolerated by clients
Face tent
An opening into the trachea through the neck where a tube is usually inserted through the opening and an artificial airway is created
Tracheostomy
True or False:
The position for tracheostomy is semi-fowlers or fowler’s position
True
Aspirating secretions through a catheter connected to a suction machine or wall suction outlet
Suctioning
True or False
Sterile technique is recommended for all suctioning to avoid introducing pathogens into the airway
True
Giving the client breaths that are 1-1.5 times the tidal volume set on the ventilator through ventilator circuit or via manual resuscitation bag
Hyperinflation
Done with a manual resuscitation bag or through the ventilator and is performed by increasing the 02 flow (usually to 100%) before suctioning and between suction attempts
Hyperoxygenation
What are the three types of catheters used in suctioning?
Whistle-tipped catheter
Open-tipped catheter
Yankauer suction catheter
True or False:
During the oropharyngeal, nasopharyngeal, and nasotracheal suctioning, an unconscious client must be positioned in a semi-fowlers position.
False - lateral position facing the nurse
