הבדיקה הגופנית של חולה במצוקה נשמתית – פתופיזיולוגיה נשמתית דר' פאולו פרישו החטיבה להרדמה בית חולים סורוקה The mechanical function of the respiratory system is to accomplish Alveolar Ventilation. Its main homeostatic responsibility is the maintenance of normal levels of O2, CO2 and pH in blood. Some Respiratory Acronyms • PaO2 - Partial Arterial Pressure of O2 • PAO2 - Partial Alveolar Pressure of O2 (BarP-47) * FiO2 - PaCO2 • SpO2 - Pulse oximetry • PaCO2 - Arterial Partial Pressure of CO2 • PETCO2 - End Tidal CO2 Pressure • Vt - Tidal Volume • RR - Respiratory Rate • Vm - Minute Volume • Va - Alveolar Ventilation • FiO2 – Fractioned Inspiratory O2 הבדיקה הגופנית של חולה במצוקה נשימתית History Physical Examination Use your eyes, ears, nose, hands and devices. Devices Stethoscope Pulse Oximeter Capnograph SpO2 Interpretation What are the limitations of SpO2? What is the meaning of a SpO2 of 100%? Capnography Trace What are its uses? Auscultation Percussion Palpation Assess Consciousness Behavior Color Sweat Speech Work of Breath Cyanosis Interpretation Is a hypoxemic patient always cyanotic? Can a patient with a normal PaO2 be Cyanotic? Work of Breath Respiratory Rate Tachypnea Bradypnea Respiratory Pattern What is the pattern of the respiratory disorder caused by opiates?

Case 2 A 70 years old lady with shortening of breath Case 3 A 18 years old girl with tachypnea Case 4 A 24 years old girl with tachypnea. Case 5 A 4 years old boy with respiratory distress Case 6 A 44 years man after an emergency cholecystectomy, with an SpO2 of 82 in the RR. Case 7 A 20 years “Golani” after an elective arthroscopy of knee, with an SpO2 of 82 in the RR. Case 8 A 28 years old, healthy woman, with an SpO2 that dropped down to 82 after ETT insertion for General Anesthesia. Case 9 A chronic ill patient with worsening of his chronic condition. Case 10 An unconscious patient immediately after MVA is breathing 20 BPM, on auscultation there is a lot of noise, but air can be heard entering both lungs. Case 11 A patient after MVA, 38 RPM, pulse , 8 bpm, cyanosis. Case 12 65 years old man, shortness of breath. Case 13 A 5 years old girl with fever and dyspnea Case 14 A 68 years old heavy smoker with dyspnea. Case 15 A 20 year old man found partially conscious A 55 YO woman in a full-blown pulmonary edema, was treated with O2 by mask with bag, high flow of 100% O2. SpO2 100%, but the she is refusing to use the mask, trying to take it off every time it is put in. Why is this patient with acute respiratory failure, cannot tolerate an oxygen mask with a high FiO2? A 70 YO CIHD patient is in the ER for 20 minutes receiving a protocol for Pulmonary Edema. The SpO2=100% with a respiratory rate of 40 bpm. What to do next?
