Nasal cannula

Patients with an oxygen saturation less than 90% (less than 95% in children, pregnant women, and patients with co-existing heart disease) should receive oxygen with the dose adjusted to keep oxygen saturation above these levels.3,12,40 Hypoxemia usually results from a ventilation/perfusion mismatch, and low oxygen levels (less than 30% of the fraction of inspired air) administered by nasal cannula or facemask are sufficient to reverse hypoxemia in most patients. 

It has been forty-five minutes since CH s arrival, and he has been given lorazepam 4 mg twice and loaded with 1500 mg of phenytoin. He received another 400 mg dose of phenytoin 15 minutes ago, but is still unarousable. His jerking movements have slowed down, but his temperature is now 39.9°C (103.8°F), and his blood pressure has dropped to 124/62 mm Hg. His oxygen saturation is 91% on 4 L oxygen via nasal cannula. Bilateral crackles are heard upon auscultation of his lungs. A CT scan of his head is obtained which shows no evidence of hemorrhage, tumor, or mass effect. 

Supplemental 02 should be initiated at the earliest signs of shock, beginning with 4 to 6 L/min via nasal cannula or 6 to 10 L/min by face mask. 

Body orifices should be decontaminated next using swabs and irrigation. A Morgan lens or nasal cannula (small tube used for draining body cavities) may be used to decontaminate the eyes. Again, runoff should be controlled to prevent the spread of contamination. 

Driving gas for nebulised therapy must be specified in the prescription. If oxygen is needed during nebuliser therapy, nasal cannulae should be used. Care must be taken with the nasal route, as it is difficult to predict the amount of oxygen inspired. 

In a randomized, double-blind, placebo-controlled, crossover study of the use of nitric oxide in chronic obstructive pulmonary disease (COPD) 11 patients with documented severe COPD received 25 ppm of nitric oxide combined with supplementary oxygen at a flow rate of 2 1/minute via nasal cannulae (8). Four of the patients reported an increase in cough and a feeling of retrosternal rawness after breathing nitric oxide for 24 hours two had an increase in dyspnea, and one developed... 

PE His initial vital signs were significant for BP 210/120 mm Hg, HR 80 beats/min, RR 18 breaths/min, and O2 saturation 98% on 6 liters oxygen by nasal cannula. In the ED, PB was started on IV infusions of nitroglycerin, metoprolol, and heparin. The patient was ruled in for acute Ml, with first creatine kinase (CK) of 137 lU/L, then peaking to 467 lU/L. Troponin was elevated at 0.95. ECG showed an ST segment elevation with no Q wave. 

I also suggest that you take "EWOT"—Exercise With Oxygen Therapy. This is accomplished by exercising on a stationary bicycle (or other exercise modality if the bike is too difficult), while breathing oxygen through a nasal cannula at six to eight liters a minute. 

The most practical means of administering long-term oxygen is with the nasal cannula, at 1 to 2 L/min which provides 24% to 28% oxygen. The goal is to raise the PaOj above 60 mm Hg. Patient education about flow rates and avoidance of flames (i.e., smoking) is of the utmost importance. 

Treatment of Cora s congestive heart failure will include efforts to reduce the workload of the heart with diuretics and other load reducers, attempts to improve the force of left ventricular contraction with digitalis and other inotropes, and the administration of oxygen by nasal cannula to reduce the injury caused by lack of blood flow (ischemia) to the viable heart tissue in the vicinity of the infarction. 

Continuous pulse oximetry monitoring, order oxygen by nasal cannula or mask to maintain sat greater than 95%... 

Oxygen via nasal cannula at 2 L/min for a client diagnosed with pneumonia. 

The UAP encourages the client to wear the nasal cannula at all times. 

The PaO is low (normal is 80-100) therefore, the nurse should administer oxygen via a nasal cannula. Oxygen is considered a medication.

Alea Suarez, age 24, was admitted 2 days ago after a car accident in which she suffered a head injirry with a subdirral hematoma (bleeding inside the skull) and a fracture at the base of the skull. Ms. Suarez is drowsy but oriented to person, place, and time. Vital signs reveal blood pressure (BP) 100/30 mm Hg, pulse (P) 110 beats/minute (faint), respiration (R) 10 breaths/minute (shallow), and temperature (T) 36.8°C. Ms. Suarez is receiving 2 L of oxygen via nasal cannula. The nurse notes that her mine output has increased and today is averaging 250 mL/h. Diagnostic blood tests are done and reveal...
