ICU Equipment fully solved graded A+ 2023/2024

ICU EquipmentWhat is an ICU? - correct answer An organized system for the provision of care to critically ill patients, with the ability to provide: - Intensive and specialized medical nursing care - An enhanced capacity for monitoring - Multiple modalities of physiologic organ support to sustain life during a period of life-threatening organ system insufficiency What are the subspecialty ICUs? - correct answer SICU, CVICU, NICU What is the nursing to patient ratio in an ICU? - correct answer 1:1 or 1:2 What is an arterial (ART) line? - correct answer Catheter that monitors arterial pressure Why is an ART line used? - correct answer - Monitors blood pressure and pulse - Access for blood draws for blood gas monitoring - Delivery of medication/fluid How is an ART line connected to the patient? - correct answer Inserted directly into an artery, preferably in the UE What is the transducer attached to the ART line leveled with? - correct answer Midaxillary line, so readings are dependent on patient position What should you not use on the extremity with an ART line? - correct answer NO BP cuff What happens if the ART line gets pulled? - correct answer There will be a lot of blood, not enough to kill someone but still not good - apply immediate pressure and then a pressure dressing What is mean arterial pressure (MAP)? - correct answer Average blood pressure during 1 cardiac cycle - You spend 2/3 of your cardiac cycle in diastole, so when measuring perfusion to the organs it should be given 2/3 of the weight What is the formula for MAP? - correct answer (Diastolic + Diastolic + Systolic)/3 Why is MAP used? - correct answer - In the ICU, one of the most important concerns is perfusion (blood flow) to the vital organs - Considered a better indicator of perfusion than systolic BP What is the normal MAP? - correct answer 70-100 mmHg What must MAP be to maintain blood supply to the heart, brain, and kidneys? - correct answer 60 mmHg What is a Swan-Ganz catheter AKA pulmonary-artery (PA) catheter? - correct answer Line that will give a more direct measure of the pressures in and around the heart Why is a PA catheter used? - correct answer - Direct measurement of right arterial pressure, right ventricular pressure, pulmonary artery pressure; indirectly measures left-ventricular end diastolic pressure - Measures function of the heart post MI, heart failure, open heart surgery How is a PA catheter connected to the patient? - correct answer Catheter inserted through the IJ or subclavian vein → superior vena cava → right atrium → right ventricle → pulmonary artery What are the PT implications for a PA catheter? - correct answer - Follow your facility's policy on mobilizing patients with these catheters - If a patient has this line, their heart is likely not in tip-top shape - Stat page to surgery if this gets pulled
