When listening to the patient I would expect to hear crackles and wheezing. 2. Normal oxygen saturation is 95% to 100%. 3.Since the patient does have a history of diabetes and asthma‚ he has a higher risk of contracting viruses due to the fact that diabetes lowers your immune response‚ and asthma causes your airway to become more sensitive.

Tables of Normal Values (As of January 2013) Note: Values and units of measurement listed in these tables are derived from several resources. Substantial variation exists in the ranges quoted as “normal” and may vary depending on the assay used by different laboratories. Therefore‚ these tables should be considered as directional only. Some values (e.g. hormones) vary by gender‚ age‚ time of day and condition (e.g. pregnancy) so a text on endocrinology should be consulted for complete data
