Why We Need Pulse Oximeters
Pulse oximetry can be used for at-home monitoring of your oxygen level and pulse for conditions such as chronic obstructive pulmonary disease (COPD), asthma, Congestive Heart Failure (CHF) and others.
If you have a lung disease, daily exercise and activity such as walking is an important part of maintaining your health. Whether you exercise or simply move around, you require more oxygen when you are active. Your pulse oximeter, when used properly, will let you know if your oxygen level is adequate during activity.
How We Use Pulse Oximeters
In pulmonary rehabilitation, respiratory therapists often teach a breathing technique called pursed lips breathing, which can increase your oxygen level. By breathing in a deeper, slower fashion you may be able to raise your oxygen level by 3 to 4 points. Your pulse oximeter can be used as your guide. During pursed lips breathing, you breathe in through your nose and exhale slowly through pursed lips. pursed lips breathing with oximetry is especially useful when active and exercising.
