Respiratory Therapist/spirometer ques


Hi I have 2 ques. My mom got diagnosed for pneumonia. She gotvkevaquon first time withvtessalon Perles but she used an expectorant instead. But anyhow ehatvis number that should be her goal. She is using voldyne spirometer almost everyday. Also she hasn't been doing as much coughing and wheezing lately. Is that a good thing or does she need to be coughing. Her main symptom now is feeling very tired. Please advise thank u

Hi there,

A patient's Spirometry goals will always be based on their height/weight/gender variables.  Without knowing your mother's detailed medical history, I can refer you to a resource that has predicted values for patients accross the board. I hope this resource helps (may have to Copy/Paste it):

As a rule, at the Hospital I work at, we generally want to see a patient reach at least 50% of their "Goal Volume"...I say only 50%, because the goal charts are more for somebody who is reasonably healthy, whereas patients in a hospital are not at their best at that time. So, based on the chart in the link I attached, a 60 year old woman at a height of 5'6" would have a goal of 2300, so a practical in-hospital goal for her would be around 1600-1700mL. We always recommend doing this exercise every hour, at 8-12 breaths. Best advice is to take her time between breaths, and make sure she EXHALES and allows the ball to drop back down to "0" before starting a new breath.

I hope this resource helps.
