1. Nasal cannula: Provides low-to-moderate concentrations of oxygen. It is used for patients who
need supplemental oxygen but are breathing adequately on their own. The patient
can eat and talk while receiving oxygen.
2. Face mask: Provides a higher concentration of oxygen than a nasal cannula. It covers the nose
and mouth and is used when the patient needs moderate oxygen supplementa-
tion.
3. Face tent: Provides humidified oxygen around the nose and mouth without tightly covering
the face. It is useful for patients who cannot tolerate a face mask or need humidified
oxygen.
4. Oxygen Clear, odorless gas constituting 21% of the air we breathe; considered a drug and
must be prescribed based on the patient's condition.
5. Tachypnea Rapid respirations, often seen with fever, metabolic acidosis, pain, and hypoxemia.
6. Tidal volume The amount of air inspired and expired with each normal breath; approximately
500 mL in adults.
7. Cyanosis Bluish discoloration of the skin, nail beds, and mucous membranes caused by
reduced hemoglobin-oxygen saturation.
8. Hematocrit The percentage of blood that is erythrocytes/red blood cells.
9. Orthopnea Inability to breathe easily unless sitting upright or standing.
10. Lung compliance The expandability/stretchability of lung tissue; plays an important role in ventila-
tion.
11. Hypoxemia Reduced oxygen levels in the blood.
12. Dyspnea Difficulty breathing or feeling short of breath (SOB).
13. Hemoglobin Oxygen-carrying red pigment/protein in red blood cells.

14. Atelectasis Collapse of a portion of the lung.
15. Apnea Absence of breathing.
16. Surfactant Lipoprotein produced by specialized alveolar cells that acts like a detergent and
reduces surface tension of alveolar fluid.
17. Hypoxia Insufficient oxygen anywhere in the body/tissues.
18. Bradypnea Abnormally slow respiratory rate.
19. Interventions to Assess respiratory rate, depth, rhythm, and effort. Monitor oxygen saturation
Maintain Normal (SpO₂). Position the patient in High-Fowler's or semi-Fowler's position. Encourage
Respirations: coughing and deep-breathing exercises. Encourage use of an incentive spirome-
ter. Reposition and ambulate the patient as tolerated. Encourage adequate fluids
if not contraindicated to help thin secretions. Suction secretions when the patient
cannot clear the airway independently. Administer oxygen as prescribed. Monitor
for signs of hypoxia such as restlessness, cyanosis, confusion, or increased respi-
ratory effort. Manage pain so the patient can breathe and cough effectively.
20. Tripod Position: The tripod position is when the patient sits upright and leans forward, usually
resting the arms on the knees, bedside table, or another stable surface.
21. Advantage of Tri- It helps maximize lung expansion and allows the accessory respiratory muscles to
pod Position: work more effectively, making breathing easier.
22. Patients who Patients experiencing dyspnea or respiratory distress, especially those with condi-
benefit from Tri- tions such as COPD, asthma, or severe shortness of breath.
pod Position:
23. Huff Coughing: Huff coughing is a controlled coughing technique used to move secretions from
the smaller airways into the larger airways so they can be expelled.
