Flashcards in Lab 3 Deck (16):
1
Supplemental oxygen administration
is recommended for hypoxemic patients (Pao2 < 80 mmHg, Spo2 < 94%, cyanosis)
2
Clinical signs of hypoxemia
increased respiratory rate, increased respiratory effort, flaring of nostrils, cyanosis
3
Hypoxemia is ....
mostly the result of respiratory disease– which may be primary or secondary to cardiovascular disease and trauma
4
Oxygen supplementation techniques
• Flow-by oxygen
• Face mask
• Bag method
• Oxygen hood
• Nasal catheter
• Transtracheal oxygen
• Oxygen cage
5
Flow-by oxygen
• A tube is attached to an oxygen source and the open end of the tube is held approximately 6 inches from animal’s mouth and nose
6
Face mask
• Mask is placed over muzzle and connected to a rebreathing or nonrebreathing tube attached to an oxygen source
7
Bag method
• Clear plastic bag is placed around the pet carrier or box, an oxygen line is then inserted through a hole in the bag to deliver oxygen
8
Oxygen hood
• Elizabethan collar applied with the bottom 2/3’s of the front covered with Saran wrap, oxygen line is inserted through base of the collar to a point two inches from the end
• Commercial hoods are also available
9
Nasal catheter
• A flexible red rubber catheter or premade nasal cannula is inserted into the caudal aspect of the nasal cavity, the external end of the catheter is connected to an oxygen line
• Humidification of air is recommended
10
Transtracheal oxygen
• Nasal catheter is aseptically inserted into trachea between 4th and 5th tracheal ring and attached to an oxygen line
• Nasal tracheal catheters can also be passed through the nasal cavity, down the epiglottis, and into the trachea to deliver oxygen
11
Oxygen cage
• Solid enclosures whose internal environment can be controlled– oxygen concentration, humidity, and temperature can be controlled. Carbon dioxide is vented from the enclosure.
12
Orogastric Intubation
• The placement of a tube that extends from the oral cavity into the stomach
13
Purpose of Orogastric Intubation
• To administer medications and radiographic contrast agents
• To remove stomach contents
• To perform gastric lavage- rinse away sludge. Also done if animal ingests a toxin
• To administer nutrients
14
Equipment needed for Orogastric Intubation
stomach tube, mouth speculum, or a roll of tape, lubricant
15
Procedure for Orogastric Intubation
1. Restrain dog in standing or sternal recumbency
2. Premeasure tube
3. Lubricate tip of tube
4. Place speculum in oral cavity
5. Pass stomach tube
6. Check for correct tube placement
