Reduced oxygen saturation levels (but above 92%) are often encountered. Examination of the lungs with a stethoscope may reveal reduced air entry and/or widespread wheeze. [6] The peak expiratory flow can be measured at the bedside; in acute severe asthma, the flow is less than 50% of a person's normal or predicted flow. [6]
An asthma attack may include wheezing, shortness of breath, coughing, chest tightness and trouble sleeping. Not every asthma sufferer experiences all of these symptoms. Asthma Triggers
Improving cardiac function, maintaining blood oxygen saturation levels, stabilizing total body water volume and distribution Cardiac asthma is the medical condition of intermittent wheezing , coughing, and shortness of breath that is associated with underlying congestive heart failure (CHF). [ 1 ]
Measurement of PEFR requires training to correctly use a meter and the normal expected value depends on the patient's sex, age, and height. It is classically reduced in obstructive lung disorders such as asthma. Due to the wide range of 'normal' values and the high degree of variability, peak flow is not the recommended test to identify asthma.

One study found that only 33% of people presenting to an emergency department with an oxygen saturation below 90% had an increased respiratory rate. [14] An evaluation of respiratory rate for the differentiation of the severity of illness in babies under 6 months found it not to be very useful.
One of those vital signs is blood oxygen level, and in the hospital, it’s measured with a pulse oximeter. Patients with Covid-19 can sometimes have relatively mild symptoms and seem to be ...
An ABG test measures the blood gas tension values of the arterial partial pressure of oxygen (PaO2), and the arterial partial pressure of carbon dioxide (PaCO2), and the blood's pH. In addition, the arterial oxygen saturation (SaO2) can be determined. Such information is vital when caring for patients with critical illnesses or respiratory disease.
