Mrs. Johansson, a 62-year-old patient, has returned to the post-anesthesia care unit after abdominal surgery.
She has received intravenous morphine several times for severe postoperative pain.
Two hours later, the nurse finds her difficult to awaken. Her respiratory rate is 7 breaths/min, her breaths are shallow, and she does not respond normally when spoken to.
The nurse assesses her airway and breathing and obtains an urgent arterial blood gas (ABG).
Arterial blood gas (ABG) results show pH 7.16, PaCO₂ 70 mmHg, and HCO₃⁻ 24 mmol/L.

الـ PH يقول انها Acidosis
به وين الخلل بالضبط
هل CO2 مرتفع او HCO3 اللي طاح
لو CO2 مرتفع معناها Respiratory

Anne is brought to the emergency department after drinking alcohol at a party and falling, striking her head. Her friend reports that Anne became unconscious soon after the fall.
On arrival, Anne is drowsy, has slow shallow respirations, and cannot follow commands.
The team is concerned that her ventilation is inadequate and assesses her airway and breathing immediately.
An ABG is collected while emergency evaluation continues.
Arterial blood gas (ABG) results show pH 7.22, PaCO₂ 62 mmHg, and HCO₃⁻ 24 mmol/L.

اول شي تشوف الـ PH
وتحدد Acidosis او Alkalosis
بعدين تشوف HCO3 و CO2
شن صاير فيهم عشان تعرف Respiratory والا Metabolic
