What factors determine whether nasal cannula or facial mask is used?

What factors determine whether nasal cannula or facial mask is used?

Mostly convenience.: Nasal cannulas are less clumsy and obtrusive than masks, and you can eat and drink (and speak clearly) while wearing one. So whenever possible, a cannula is used. In an emergency, or during surgery, or when no cannulas are available, a mask is used. ...Read more

What is a peripheral nasal cannula to stop nose bleeds.How can one tell if is still in place?

Huh?: As an ent, I have never heard of a peripheral nasal cannula to stop nosebleeds. I am assuming you are referring to some type of nasal packing. Usually there is a string or something attached if it needs to be removed, but might not have anything for you to see. You should see the doctor who put it in for the correct followup. You may not be able to see it. ...Read more

What could it be? A bad vitamin-ey smell in nose and trach cannula? Have been taking inhaled tobramycin and cefepime through picc line for pneumonia and have been off them both for 8 days.

What could it be?  A bad vitamin-ey smell in nose and trach cannula? Have been taking inhaled tobramycin and cefepime through picc line for pneumonia and have been off them both for  8 days.

What : What other medical problems do you have? Why do you have a tracheostomy tube? What was the offending bacteria causing your pneumonia? Most importantly--how are your symptoms? Fever, breathing ok, sputum from your trach tube? As an otolaryngologist, I have a lot of experirnce with nasal/sinus issues and trach tubes. My guess is that you are recovering from a significant insult to your respiratory tract. The organisms that were treated are likely gone, but you are left with the aftermath. The lungs are likely transiently damaged and need to recover. That can include the mucociliary clearance of the mucous produced normally in the lungs as well as byproducts of the infection--these can all lead to abnormal smell from the respiratory tract. For you now, pulmonary toilet (the actions you do to cealn out your lungs, trachea, and tracheostomy tube) is going to be very imortant to clean all that "crud" out. Deep coughing and deep suction with saline "spritzes" are important, nebulized saline will loosen the secretions and allow for easier clearance. Saty hydrated. If you are having worsening symptoms, see your doctor. He or she may be able to stop a situation from getting worse and keep you out of an er or from getting admitted to the hospital. ...Read more

Why would i get tachycardia hypertensive s.O.B (put on a nasal canula) and chills after anesthesia?Happened 2 yrs ago after thyroid surgery

Why would i get tachycardia hypertensive s.O.B (put on a nasal canula) and chills after anesthesia?Happened 2 yrs ago after thyroid surgery

pain, side effect: Chills and shivering occur after anesthesia because the anesthetics impair the normal temperature regulation in the brain. This resolves after a short time in the recovery room. Increased heart rate and BP in a young healthy patient are most often secondary to post op pain and improve with adequate pain control. Oxygen is usually administered in the recovery room as anesthetics impair respiration. ...Read more

Which way is a cannula supposed to go in?

Which way is a cannula supposed to go in?

Oxygen delivery: I think you are asking about the 2-pronged oxygen or air delivery nasal cannula. Simply follow the curve of the cannula prongs as you place it into the nose. Check with the respiratory therapist for exact placement and adjustment as necessary to decrease nasal crusting, stuffiness and risk of bleeding. ...Read more
