Respiratory Assessment: Inspection, Palpation & Bedside Escalation
A green SpO₂ on the monitor does not tell you whether the patient can sustain the next walk to the bathroom. This guide teaches a repeatable I-P-A-P sequence (inspection → palpation → percussion when competent → auscultation), when symptoms and saturation diverge, and how to pair findings with pulse oximetry, lung auscultation, and timely rapid response activation.

Quick facts
Key takeaway
Treat the patient, not the monitor: inspect effort and symmetry, complete palpation and auscultation in your unit's order, and chart objective trends. When shortness of breath or hypoxia symptoms outpace the saturation number, escalate early—do not wait for a single SpO₂ to cross an arbitrary threshold.
Procedure summary
| Field | Details |
|---|---|
| Procedure name | Respiratory assessment (pulmonary assessment) |
| Also known as | Breathing assessment; respiratory examination |
| Category | Patient assessment / respiratory nursing |
| Clinical purpose | Detect changes in ventilation, gas exchange, and airway status early—before deterioration requires emergency intervention. |
| Who performs | Registered nurses, nursing students under supervision, and other credentialed clinicians. Depth of percussion and advanced interpretation varies by role and employer. |
| Typical settings | Medical and surgical wards, emergency departments, critical care, community nursing, pre-transfer checks, and post-operative recovery. |
| Time | Institutional protocols may vary; a focused assessment often takes several minutes; a full examination takes longer when posterior chest and accessory tests are included. |
What is respiratory assessment?
Respiratory assessment is the structured bedside evaluation of how a patient is breathing—from general appearance and ability to speak in full sentences through chest inspection, palpation, percussion (when within competence), and auscultation—integrated with vital signs, patient report, and device data such as pulse oximetry.
Nurses use it to answer practical questions: Is work of breathing increasing? Is expansion symmetric? Are breath sounds changed? Does mental status or skin colour suggest hypoxia or hypercapnia risk? The skill supports safe care across asthma, COPD, pneumonia, heart failure, and post-operative hypoventilation—always alongside orders for chest X-ray or arterial blood gas when the clinical picture warrants.
Clinical indications
- Admission baseline and each shift review for respiratory at-risk patients
- New or worsening cough, sputum change, chest discomfort, or shortness of breath
- SpO₂ below charted target, rising respiratory rate, or accessory muscle use
- Before and after oxygen therapy, nebulised albuterol, or chest physiotherapy when ordered
- Post-operative, immobile, or sedated patients where atelectasis and aspiration risk are high
- NEWS or local early-warning score triggers; part of head-to-toe assessment
Precautions and when to modify the exam
Respiratory assessment is rarely withheld, but technique and depth may change:
If the patient cannot speak, has severe accessory muscle use, or is rapidly tiring, complete ABCDE and call for help before a leisurely full examination. A focused check still informs immediate actions.
- Sternotomy or thoracic precautions—position and palpate gently per protocol
- Chest drains, burns, or dressings—inspect and listen around devices without dislodging them
- Contagious respiratory infections—appropriate isolation precautions
Explain exposure needs, offer a chaperone, and drape so only the chest and back required for examination are uncovered.
I-P-A-P sequence: inspection → palpation → percussion → auscultation
Many respiratory programmes teach a four-step chest exam. The unifying principle is complete the components your competence allows, in the order your trust specifies—often auscultation before palpation and percussion so manipulation does not alter breath sounds.
Inspection
Fast, high-yield at the doorway.
- Ability to speak in full sentences; distress; posture (tripod, leaning forward)
- Respiratory rate, rhythm, nasal flare, pursed-lip breathing
- Chest symmetry, deformity, scars, drains; skin and lip colour (central cyanosis)
- Cough character; audible wheeze or stridor at rest
Palpation
Symmetry and tenderness.
- Tracheal position; gentle chest wall palpation for tenderness
- Chest expansion—thumbs at costal margin or scapular line while patient inhales deeply
- Tactile fremitus (“ninety-nine” vocal fremitus) when taught in your programme
Percussion
Resonance vs dullness—scope varies.
- Performed when within competence; maps air versus fluid/consolidation
- Follow local diagrams; compare right and left at the same level
- Does not replace auscultation or imaging when clinical concern persists
Auscultation
Detailed in the lung auscultation guide.
- Systematic anterior and posterior zones; see lung auscultation
- Vesicular, bronchial, diminished, crackles, wheeze—document zone and laterality
- Re-auscultate after bronchodilator or physiotherapy to evaluate response
Full medical respiratory examination (including detailed JVP, lymph nodes, and advanced percussion interpretation) may be physician-led. Ward nurses routinely perform inspection, vital signs, SpO₂, expansion checks, and auscultation—escalate when findings change or exceed your competency framework.
When SpO₂ and symptoms disagree
Pulse oximetry estimates oxygen saturation; it does not measure work of breathing, CO₂ retention, or ventilation adequacy. Apply pulse oximetry per protocol—warm perfused site, nail polish removed when possible, plethysmograph waveform checked, probe site changed at intervals during continuous monitoring when policy requires.
| Bedside pattern | Nursing focus | Action |
|---|---|---|
| Comfortable SpO₂, rising work of breathing | Silent or impending deterioration—do not reassure from one number | Full respiratory assessment, notify clinician, prepare escalation pathway |
| High SpO₂, drowsiness in COPD risk | Consider hypercapnia; follow charted target band | Notify clinician; avoid uncontrolled high-flow oxygen without orders |
| Low SpO₂, patient appears comfortable | Check probe site, perfusion, and waveform artefact | Relocate sensor, reassess clinically, document device and symptoms |
| Cyanosis with “normal” saturation | Anaemia, poor perfusion, CO exposure, or device error | Treat the patient; escalate; do not chart WNL without context |
Prescribed oxygen targets (for example lower bands in COPD) are medical decisions—nurses implement, monitor, and report trends. See oxygen therapy administration for when to change delivery devices.
CO₂ retention and hypercapnia cues nurses can screen for
You are not diagnosing acid–base status at the bedside, but you can recognise combinations that warrant urgent medical review—especially in COPD and after high-dose bronchodilator therapy:
- Reduced consciousness, headache, or confusion with rising respiratory rate or shallow breathing
- Coarse flapping tremor of outstretched hands when assessing for CO₂ retention (per local examination teaching)
- SpO₂ above the patient's prescribed target with new somnolence after oxygen increase
- Failure to improve work of breathing despite bronchodilator and oxygen adjustments—prepare for arterial blood gas sampling when ordered
Worsening asthma attack features (silent chest, exhaustion, unable to speak) need emergency escalation regardless of a single saturation reading—pair with peak flow measurement when the patient can cooperate.
Equipment
Patient preparation
Verify and explain
Confirm identity, describe inspection of breathing pattern, chest listening, and SpO₂ check; gain consent. Pause if severe dyspnoea needs positioning or oxygen adjustment first.
Optimise position
Sitting upright is ideal when safe so anterior and posterior chest can be accessed. If not, side-lying with help after abdominal or spinal precautions per protocol.
Reduce artefacts
Quiet room if possible; minimise shivering and excessive movement during oximetry. Maintain comfortable room temperature when feasible.
Hand hygiene and PPE
Perform hand hygiene; apply PPE per transmission risk.
Step-by-step respiratory assessment
Global inspection
Note ability to speak in full sentences, alertness, skin colour, and visible distress. Count respiratory rate for a full minute when possible; note oxygen device and flow.
Pulse oximetry
Select a warm site with good perfusion; remove nail polish on the probed finger when possible; secure probe without excessive pressure; allow reading to stabilise; compare pulse on device with palpated pulse when policy requires.
Inspect the chest
Observe symmetry, expansion, scars, deformity, and use of accessory muscles. Listen for audible wheeze or stridor before the stethoscope.
Palpate
Check tracheal position; light palpation for tenderness; assess expansion bilaterally at the same level during deep inspiration.
Percuss (if competent)
Percuss systematically comparing sides; note dull or hyperresonant areas per local teaching.
Auscultate
Complete bilateral lung auscultation using your unit map—see lung auscultation for zone sequencing and documentation standards.
Integrate and act
Correlate findings with symptoms, SpO₂ versus target band, and early-warning score. Initiate ordered oxygen or bronchodilator therapy; notify when trends worsen; document objectively.
Monitoring and escalation
- Unable to speak in full sentences with rapid fatigue and falling SpO₂ despite oxygen
- Stridor at rest; suspected airway obstruction
- Sudden unilateral chest findings with hypoxia—consider pulmonary embolism or pneumothorax pathways per protocol
- Altered consciousness with respiratory depression or CO₂ retention concern
- SpO₂ persistently below charted target after correct probe placement
- New focal crackles with fever, purulent sputum, or rising early-warning score
- Worsening wheezing not responding to prescribed bronchodilator plan
- Post-operative diminished bases not improving with incentive spirometry and positioning
Activate rapid response or emergency pathways per unit criteria when the patient is deteriorating faster than ward resources can manage.
Nursing documentation
Record date/time, position, respiratory rate, SpO₂ with probe site and oxygen device (type and flow), charted target band, work of breathing, chest inspection, palpation and auscultation findings with laterality, comparison to prior entry, interventions, and notifications.
Weak entry
“RR 22, SpO₂ 94%, lungs clear.”
Stronger entry
“RR 22, SpO₂ 94% right index on 2 L NC (target 94–98%). Accessory use mild. Posterior bases: fine crackles R>L (new). Patient reports SOB at rest. Dr notified.”
Clinical pearls for nurses
- Begin with inspection and conversation—rate and effort often declare trouble before the stethoscope warms up.
- Always chart the oxygen target band next to SpO₂ so night staff know whether 92% is acceptable or alarming.
- Include posterior assessment in immobile and post-operative patients—anterior fields can sound deceptively clear.
- Re-assess after nebuliser, physiotherapy, or diuretic therapy; document whether air entry and symptoms improved.
- When in doubt, trend against that patient's baseline rather than a textbook “normal.”
NCLEX practice questions
When sentences shorten while the saturation still looks acceptable, NCLEX-style clinical judgment practice for respiratory assessment rehearses priority action when effort and SpO₂ diverge, select-all-that-apply exam technique, trend interpretation after diuretic therapy, matrix escalation for airway and COPD risk, and documentation cloze—recognise cues → analyse → prioritise → act → evaluate outcomes.
Unfolding case — respiratory ward. Mrs. Chen, 70, has COPD and a written oxygen target 88–92%. She reports increased shortness of breath since breakfast. Vitals: temperature 37.1 °C, heart rate 102, blood pressure 138/76 mmHg, respiratory rate 26, SpO₂ 96% on 2 L/min nasal cannula. She opens eyes to voice but speech is slowed; inspection shows mild accessory muscle use. Yesterday's note described vesicular sounds with scattered expiratory wheeze only.
Answer key & rationale
Frequently asked questions
What is included in a nursing respiratory assessment?
At minimum: inspection of breathing pattern and effort, respiratory rate, pulse oximetry with context, chest expansion, and auscultation. Palpation, percussion, and advanced examination steps depend on competence and local policy.
Should I auscultate before or after palpation?
Many protocols auscultate before palpation and percussion so manipulation does not alter breath sounds. Follow your institution's respiratory examination sequence.
Is pulse oximetry enough for respiratory monitoring?
No. SpO₂ does not measure ventilation or CO₂ retention. Pair oximetry with respiratory rate, symptoms, and full assessment when findings diverge.
How often should respiratory assessment be repeated?
Frequency depends on acuity and policy—often each shift minimum for stable patients, and more often when early-warning scores rise or oxygen requirements change. Institutional protocols may vary.
When must I escalate immediately?
Escalate for airway compromise, inability to maintain speech with fatigue, stridor, sudden unilateral findings with hypoxia, or altered consciousness with respiratory compromise—per your unit emergency criteria.
Can respiratory assessment replace a chest X-ray?
No. Bedside assessment detects clinical change; imaging answers different questions. Use both with timely orders when cues warrant.
