CARE 2025
Key Terms/Concepts
Hypoxia: A condition in which there is a deficiency of oxygen in
the tissues, which can lead to cyanosis and other symptoms.
Kussmaul Respirations: Deep, labored breathing pattern often
associated with metabolic acidosis, characterized by an increased
rate and depth of breathing.
Venturi Mask: A type of oxygen delivery system that provides a
precise concentration of oxygen to the patient, often used for
patients who require controlled oxygen therapy.
Interventions
Water-soluble lubricant: Recommended for clients receiving
oxygen via nasal cannula to prevent irritation and dryness of the
nasal mucosa.
Monitoring for cyanotic mucous membranes: A critical
assessment for hypoxia in postoperative patients.
Key Procedures/Protocols
Postoperative Care: Monitoring vital signs and oxygenation
status in clients who have undergone surgery, particularly those
under general anesthesia.
Symptoms
Cyanotic Mucous Membranes: A sign of hypoxia that indicates
inadequate oxygenation in the body.
Key Oxygen Delivery Systems
System Description
Delivers low-flow oxygen, typically 1-6 L/min, suitable
Nasal Cannula
for mild hypoxia.
Simple Face Provides moderate oxygen concentration (40-60%) at 6-
Mask 10 L/min.
Delivers precise oxygen concentrations, ideal for patients
Venturi Mask
needing controlled therapy.
Facts to Memorize
Normal oxygen saturation levels: 95-100%
, Kussmaul respirations are deep, labored breaths often associated
with metabolic acidosis.
Venturi mask delivers a precise concentration of oxygen, typically
used for patients requiring controlled oxygen therapy.
Simple face mask provides 40-60% oxygen concentration at flow
rates of 5-10 L/min.
Reference Information
Signs of hypoxia include cyanosis, confusion, and shortness of
breath.
Oxygen delivery systems include nasal cannula, simple face mask,
Venturi mask, and non-rebreather mask.
