The nasal cannula (NC) is a device used to deliver supplemental oxygen or increased airflow to a patient or person in need of respiratory help. This device consists of a lightweight tube which on one end splits into two prongs which are placed in the nostrils curving toward the sinuses behind the nose, and from which a mixture of air and oxygen flows.

The amount of oxygen available to the patient in mouth-to-mouth is around 16%. If this is done through a pocket mask with an oxygen flow, this increases to 40% oxygen. If either a bag valve mask or a mechanical ventilator is used with an oxygen supply, this rises to 99% oxygen. The greater the oxygen concentration, the more efficient the ...
Oxygen therapy, also referred to as supplemental oxygen, is the use of oxygen as medical treatment. [1] Supplemental oxygen can also refer to the use of oxygen enriched air at altitude. Acute indications for therapy include hypoxemia (low blood oxygen levels), carbon monoxide toxicity and cluster headache .
An oxygen mask is a mask that provides a method to transfer breathing oxygen gas from a storage tank to the lungs. Oxygen masks may cover only the nose and mouth (oral nasal mask) or the entire face (full-face mask). They may be made of plastic, silicone, or rubber. In certain circumstances, oxygen may be delivered via a nasal cannula instead ...
Unlike the non-rebreather and partial rebreather masks, the simple face mask lacks a reservoir bag. It also has holes in the mask instead of the non-rebreather's one-way valves, so ambient air can enter the mask. This feature eliminates the danger of suffocation present if a mask with one-way valves becomes disconnected from oxygen.
VO2 max is a score that quantifies how much oxygen your body absorbs and uses while working out, says sports medicine doctor and professor of orthopaedic surgery Dr. Alexis Chiang Colvin. V stands ...
Tracheal tubes can be used to ensure the adequate exchange of oxygen and carbon dioxide, to deliver oxygen in higher concentrations than found in air, or to administer other gases such as helium, [27] nitric oxide, [28] nitrous oxide, xenon, [29] or certain volatile anesthetic agents such as desflurane, isoflurane, or sevoflurane.
Essentially, kegel exercises are a way of contracting the muscles of the pelvic floor, which give you greater control and intensity during sex. Try lifting your penis up and down with your muscles ...
