Nasal Cannula
Nasal Cannula
A nasal cannula is one of the most widely used devices in oxygen therapy. The nasal cannula is designed to deliver supplemental oxygen directly to a patient’s nose. It consists of soft prongs that sit just inside the nostrils, connected to tubing that supplies oxygen from a source such as a concentrator or oxygen tank. The flexibility and simplicity of this device make it suitable for both hospital and home use.
Low Flow Nasal Cannula
A low flow nasal cannula typically provides oxygen at flow rates ranging from 1 to 6 liters per minute. This method supplies oxygen mixed with room air – becoming an effective option for patients with mild to moderate oxygen needs. It is lightweight, comfortable for long-term use, and allows patients on oxygen therapy to eat, speak, and move freely while still receiving oxygen support. Low flow systems are commonly prescribed for individuals with chronic respiratory conditions such as COPD or for short-term recovery after illness or surgery.
High Flow Nasal Cannula
Nasal high flow cannula therapy delivers oxygen at much higher flow rates, often between 30 and 60 liters per minute. High flow systems are equipped with heated humidification, which prevents airway dryness and improves tolerance for prolonged use. They are particularly useful in acute care settings and help reduce the work of breathing.
Nasal Cannula Oxygen Flow
Oxygen can be delivered at adjustable rates using O₂ nasal cannula, flow nasal cannula, and nasal cannulas. Careful monitoring by respiratory therapists and caregivers ensures the correct flow is provided to meet patient needs without causing discomfort or complications.
Critical care Oxygen Therapy with Nasal Cannulas
Whether using low flow for routine therapy or high flow for critical support, the nasal cannula remains an essential tool in oxygen delivery for respiratory care, balancing effectiveness with patient comfort and convenience.
