🫁 The Nasal Cannula is the most commonly used low-flow oxygen delivery device.

It delivers supplemental oxygen through two small prongs placed in the nostrils, making it comfortable for patients who need mild oxygen support.

Think:

🧠 Nasal Cannula = Low-Flow Oxygen

Oxygen delivery:

✅ FiO₂: 24–44%
✅ Flow rate: 1–6 L/min

Common indications include:

🚨 Mild hypoxemia
🚨 COPD (low-flow oxygen as prescribed)
🚨 Congestive heart failure (CHF)
🚨 Post-operative oxygen therapy
🚨 Patients requiring long-term oxygen support

💡 NCLEX Tip:

Increase oxygen by approximately 4% for every 1 L/min delivered.

Always assess the patient’s SpO₂, respiratory status, and clinical condition—treat the patient, not just the number.

Remember the progression of oxygen devices:

🫁 Nasal Cannula → Simple Mask → Non-Rebreather Mask

As oxygen requirements increase, move to a device capable of delivering a higher FiO₂.

At Nexora™, we simplify respiratory care through:

✨ visual learning
✨ high-yield NCLEX education
✨ NGN clinical judgment
✨ easy-to-understand rationales

Because understanding oxygen therapy helps you make safer clinical decisions. 💙

🫁 The Non-Rebreather Mask (NRB) delivers one of the highest concentrations of oxygen without mechanical ventilation.

It includes a reservoir bag and one-way valves that help prevent the patient from rebreathing exhaled air, allowing delivery of high levels of oxygen.

Think:

🧠 Non-Rebreather = Maximum Oxygen

Oxygen delivery:

✅ FiO₂: 60–95%
✅ Flow rate: 10–15 L/min

Common indications include:

🚨 Severe hypoxemia
🚨 Acute respiratory distress
🚨 Trauma or major injury
🚨 Carbon monoxide poisoning
🚨 Shock
🚨 Pre-intubation oxygenation

💡 NCLEX Tip:

Always ensure the reservoir bag is inflated before placing the mask on the patient. The bag should remain at least one-third to one-half inflated during inspiration for effective oxygen delivery.

Remember:

🫁 Nasal Cannula → Simple Mask → Non-Rebreather

As oxygen needs increase, move to a device that delivers a higher FiO₂.

At Nexora™, we simplify respiratory care through:

✨ visual learning
✨ high-yield NCLEX education
✨ NGN clinical judgment
✨ easy-to-understand rationales

Because understanding oxygen delivery saves lives. 💙

😷 Simple Mask is a commonly used oxygen delivery device that provides a higher concentration of oxygen than a nasal cannula.

It delivers an FiO₂ of approximately 40–60% with a flow rate of 6–10 L/min.

A Simple Mask is commonly indicated for:

✅ Mild to moderate hypoxemia
✅ Shortness of breath
✅ Post-operative oxygen therapy
✅ Patients requiring more oxygen than a nasal cannula can provide

💡 NCLEX Tip:

Always set the oxygen flow rate to at least 6 L/min when using a Simple Mask. Lower flow rates can cause carbon dioxide (CO₂) to accumulate inside the mask, leading to rebreathing.

🧠 Easy way to remember:

Simple Mask = 6–10 L/min = 40–60% FiO₂

At Nexora™, we simplify oxygen delivery devices with:

✨ High-yield NCLEX education
✨ Visual learning
✨ Easy-to-remember charts
✨ NGN clinical judgment training
✨ Real-world nursing concepts

Because understanding oxygen therapy is essential for safe patient care. 💙

🩸 METABOLIC ALKALOSIS occurs when the body has too much bicarbonate (HCO₃⁻) or loses too much hydrogen (H⁺), causing the blood to become more alkaline.

Think:

🧠 ↑ HCO₃⁻ = ↑ pH = Metabolic Alkalosis

Common causes include:

⚠️ Prolonged vomiting
⚠️ Nasogastric (NG) suctioning
⚠️ Loop or thiazide diuretics
⚠️ Excessive antacid use
⚠️ Hypokalemia

Classic ABG findings:

✅ pH ↑ (> 7.45)
✅ HCO₃⁻ ↑ (> 26 mEq/L)

Common signs and symptoms:

🚨 Muscle cramps
🚨 Muscle weakness
🚨 Tingling or numbness
🚨 Confusion
🚨 Cardiac dysrhythmias (severe cases)

💡 NCLEX Tip:

Metabolic Alkalosis = High bicarbonate.

The lungs compensate by slowing respirations to retain CO₂ and help lower the pH.

A simple memory trick:

🫁 “HCO₃⁻ goes up, pH goes up.”

At Nexora™, we simplify difficult concepts using:

✨ visual learning
✨ NGN clinical judgment
✨ high-yield NCLEX education
✨ easy-to-understand rationales

Because once you understand the WHY, ABGs become much easier. 💙

🩸 METABOLIC ACIDOSIS occurs when the body produces too much acid or loses too much bicarbonate (HCO₃⁻).

As bicarbonate decreases, the blood becomes more acidic, causing the pH to fall.

Think:

🧠 ↓ HCO₃⁻ = ↓ pH = Metabolic Acidosis

Common causes include:

⚠️ Diabetic ketoacidosis (DKA)
⚠️ Lactic acidosis
⚠️ Renal failure
⚠️ Severe diarrhea
⚠️ Sepsis
⚠️ Toxic ingestions

Classic ABG findings:

✅ pH ↓ (< 7.35)
✅ HCO₃⁻ ↓ (< 22 mEq/L)

Common signs and symptoms:

🚨 Kussmaul respirations
🚨 Confusion
🚨 Weakness
🚨 Fatigue
🚨 Nausea and vomiting
🚨 Cardiac dysrhythmias (severe cases)

💡 NCLEX Tip:

Metabolic Acidosis = Low bicarbonate.

The lungs try to compensate by increasing the respiratory rate to blow off CO₂ and raise the pH.

A simple memory trick:

🫁 “HCO₃⁻ goes down, pH goes down.”

At Nexora™, we simplify difficult concepts using:

🫁 RESPIRATORY ALKALOSIS occurs when the lungs remove too much carbon dioxide (CO₂) due to hyperventilation.

As CO₂ decreases, the blood becomes more alkaline, causing the pH to rise.

Think:

🧠 Hyperventilation = ↓ CO₂ = Respiratory Alkalosis

Common causes include:

⚠️ Anxiety or panic attacks
⚠️ Pain
⚠️ Fever
⚠️ Pulmonary embolism
⚠️ Early salicylate toxicity
⚠️ High altitude

Classic ABG findings:

✅ pH ↑ (> 7.45)
✅ PaCO₂ ↓ (< 35 mmHg)

Common signs and symptoms:

🚨 Rapid breathing (tachypnea)
🚨 Lightheadedness or dizziness
🚨 Tingling around the mouth or fingers
🚨 Muscle cramps
🚨 Anxiety

💡 NCLEX Tip:

Respiratory Alkalosis = Too little CO₂.

When a patient breathes too fast, excessive CO₂ is blown off, causing the blood to become alkaline.

A simple memory trick:

🫁 “CO₂ goes down, pH goes up.”

🫁 RESPIRATORY ACIDOSIS occurs when the lungs cannot remove enough carbon dioxide (CO₂) from the body.

As CO₂ builds up in the bloodstream, the blood becomes more acidic, causing the pH to decrease. 🩸

Think:

🧠 Hypoventilation = CO₂ Retention = Respiratory Acidosis

Common causes include:

⚠️ COPD exacerbation
⚠️ Respiratory failure
⚠️ Opioid overdose
⚠️ Sedative medications
⚠️ Neuromuscular disorders
⚠️ Severe asthma

Classic ABG findings:

✅ pH ↓ (< 7.35)
✅ PaCO₂ ↑ (> 45 mmHg)

Common signs and symptoms:

🚨 Hypoventilation
🚨 Dyspnea
🚨 Drowsiness
🚨 Headache
🚨 Confusion
🚨 Decreased level of consciousness

💡 NCLEX Tip:

Respiratory Acidosis = Too much CO₂.

If the patient isn’t ventilating effectively, carbon dioxide accumulates and the blood becomes acidic.

A simple memory trick:

🫁 “CO₂ goes up, pH goes down.”

At Nexora™, we simplify difficult concepts using:

🩸 ABGs (Arterial Blood Gases) are one of the MOST important concepts in nursing, critical care, and NCLEX preparation.

ABGs help nurses evaluate:

🫁 Oxygenation
🫁 Ventilation
🩸 Acid-base balance

The normal values every nursing student should know:

✅ pH: 7.35 – 7.45
✅ PaCO₂: 35 – 45 mmHg
✅ HCO₃⁻: 22 – 26 mEq/L
✅ PaO₂: 80 – 100 mmHg
✅ SaO₂: 95 – 100%

A simple NCLEX approach:

🧠 pH = Acidosis or Alkalosis?

🧠 PaCO₂ = Respiratory Component

🧠 HCO₃⁻ = Metabolic Component

Common ABG disorders include:

⚠️ Respiratory Acidosis
(COPD, hypoventilation, respiratory failure)

⚠️ Respiratory Alkalosis
(Hyperventilation, anxiety, pulmonary embolism)

⚠️ Metabolic Acidosis
(DKA, sepsis, renal failure)

⚠️ Metabolic Alkalosis
(Vomiting, NG suctioning, diuretic use)

💡 NCLEX Memory Trick:

ROME

🫁 Respiratory = Opposite

🩸 Metabolic = Equal

This helps quickly determine whether the disorder is respiratory or metabolic.

At Nexora™, we simplify difficult concepts using:

✨ visual learning
✨ NCLEX-focused education
✨ NGN clinical judgment
✨ easy-to-understand rationales
✨ high-yield nursing content

Because understanding ABGs shouldn’t feel overwhelming. 💙
