DiagnosticsI.Respiratory Diagnostic ProceduresA.Pulmonary Function Tests – determine lung function and breathing difficulties1.Commonly performed for clients who have dyspnea and to identify clients w/ respiratory risks before surgery2.If smoker – do not smoke 6-8 hrs before test3.If using inhaler – withhold 4-6 hrs prior to testB.ABGs – reports status of oxygenation and acid-base balance of the blood1.Obtained by arterial puncture or through arterial line2.Arterial Linea.Preop1)Obtain heparinized syringe for sample collection.2)Perform Allen’s test – Compress ulnar and radial arteries simultaneously. Instruct client to form a fist. Have client relax his hand while releasing pressure on radial artery. Hand should turn pink quickly. Repeat process for ulnar artery.3)Explain and reinforce procedure to clientb.Intraop1)Perform arterial procedure w surgical aseptic technique and collect specimen into heparinized syringe. Collect specimen into heparinized syringe.2)Place collected and capped specimen into basin of ice and water. Transport to lab immediately.c.Postop1)Hold direct pressure over the site for at least 5mins. Maintain pressure for at least 20 mins if pt is on anticoag therapy. Ensure that bleeding has stopped before removing pressure.2)Monitor ABG sampling site for bleeding, loss of pulse, swelling, temp. changes and color3)Document all interventions and client’s response.4)Administer O2. Change ventilator settings as ordered or notify RT. *Arterial puncture is typically done by RT3.Arterial Linea.Preop1)Verify that line may be used for specimen collection. Obtain heparinized syringe for sample collection. Standard syringe for waste2)Explain and reinforce procedure w/ clientb.Intraop1)Collect waste and specimen. Place both on ice for transport2)Flush arterial line w/ preconnected flushing system.
