Question

Case Studies A 28 year old woman presents to the emcrgency department with complaints of difficulty breathing, general muscle weakness and dysphagia. Her history of present illness reveals that she was diagnosed wtih infectious mononucleosis 10 days ago and had recently experienced ptosis and weakness in her legs and amis. She weighs 150 pound and is 5 feet, 8 inches tall. ABG on room air: 730502378 S02 91% H maximal inspiratory pressure is 15 1. cmH20 and vital capacity is 13 ml/kg. What is the most e action at this time? Calculate the patient's minute ventilation using the chant. What tidal volume and respiratory rate ranges would be appropriate for this patient? Fiflcen minutes later the patient's breathing is very shallow; she is unresponsive and is immediately intubated Suggest an appropriate mode of ventilation for this patient. Explain your choice. What ventilator settings would you recommend? (all applicable settings for specific 2. A motor vehicle crash victim arives at the hospital via air ambulance. The 27 year old has sustained a closed head injury. Physical assessment reveals a HR 145, RR 32 and BP 155/97, His neck veins are distended and he is diaphoretic. He is 72 incbes tall and weighs 220 lbs. The patient has no history of cardiac or respiratory dease. The patient has an oral airway in place with a weak gag reflex. On 60% oxygen, the ABG is 722642578 with SaO2 92%. What type of respiratory failure appears to be present in this patient? What acid-base imbalance is present? What type of mechanical ventilatory support may this patient benefit from? What are the appropriate parameters for this patient,including minute venilatio, idal volume,inspiratory time, flow rate and PEEP?

Answer 1

1, patient pao2, paco2 level decreased , HCo3 with in normal range.patient is in respiratory alkalosis..patient vital capacity increased..patient should be ventilated immediately..

2, minute ventilation ( VE) is the quantity of air moved in and out of the lungs in minute and CO2 elimination from alveoli..it can be found by multiplying respiratory rate and tidal volume..
