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

Cases
Case 1
An unconscious young man found in the street with a
heavy snoring.
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?
