sputum production > 30 ml/ day indicates |
need for airway clearance |
|
central cyanosis indicates |
low arterial hemoglobin saturation |
|
central cyanosis appears |
when Sao2 drops blelow 80% or a PaO2 of about 45-50 torr
usually evidentas a bluish discoloration of the mucous membranes of the lips and mouth |
|
peripheral cyanosis or acrocyanosis is due to |
poor blood flow. it can occur in the presence of normal HB saturation, and tends to appear only in the extremities. When observed together with coolness of the extremities, perhipheral cyanosis suggest circulatory failure. |
|

|

|
Before administration of a prescribed bronchodilator, an asthmatic patient with wheezing has a FEV1 of 3.7 L. Thirty minutes after aerosol administration of
recommend discontinuing bronchodilator therapy
recommend decreasing the bronchodilator dosage |
recommend increasing the bronchodilator dosage
In this patient's case, the change in FEV1 is less than 10% [(4.1 – 3.7)/4.1 = 9.7%], indicates a lack of significant improvement in airway caliber. In order to relieve the patient's symptoms, you should recommend increasing the dose of the prescribed bronchodilator.
