CVR definition/range
| Question | Answer |
|---|---|
| Oxygen saturation Abrv Units Normal ranges | SaO2 % saturation >95% |
| SaO2 % in person with chronic respiratory condition | 88-92% |
| RR stands for what? What is measured/what are the units? What are normal values? | Respiratory rate Breaths per minute 12-18 in healthy adult |
| What are ABG’s? What they measuring? Why is it used? | 1)what-Arterial blood gas. 2)Measures-the PH or acidity, the O2 and CO2 levels in the blood from an artery. 3)why- Checks how well the lungs can move oxygen into the blood and co2 out. |
| What is paO2? What are the normal ranges including units? | Partial pressure of oxygen 10-13.3 KPa |
| Partial pressure of carbon dioxide in artery is abbreviated to...?Normal range is...? Include units | PaCO2 4.7-6.0 KPa |
| What is HCO3? Why is is measured? Normal values? | Bicarbonate is byproduct of metabolism. Blood takes the bicarb to lungs to be exhaled as CO2 gas. 22-26 mmol/L is normal Kidneys also regulate bicarbonate by excreting it and reabsorbing it to balance body pH (7.35-7.45) |
| What is body’s normal pH? | 7.35-7.45 |
| What is BE? What is normal range? Units please! | Base excess Acid-base balance value derived from blood pH and PaCO2 It’s the volume of acid needed to restore the blood to normal pH at PaCO2 40mmHg Norms- -2 to +2mmol/L |
| Peak Expiratory Flow Rate is maximal flow rate generated in forceful exhalation. Mainly reflects large airway flow but depends on voluntary and muscular effort of patient. Discharging-Asthmatics usually 75%+ of normal PEFR L/m Peak flow meter 300-600 | |
| Ratio between Forced expiratory volume (amount of air you can eject from lungs in 1 second) and forced vital capacity ( maximal amount of air that can be exhaled from lungs after deepest breath) Above 0.75 is normal below, suggests obstructive pattern | |
| RHR normal ranges | Below 50bpm is bradycardia and 90+ tachycardia |
| Diastolic BP is..? | The bottom number S/D Pressure in the arteries at when heart rests between beats 60-90 normal ranges mmHg |
| Systolic BP is...? I.e. top or bottom number? Normal ranges and include units? | The top or larger number Pressure in arteries during ventricular contraction phase 90 to140 normal ranges |
| Jeff’s data says Normal blood pressure ranges are? NHS ideal range is....? | 90/60 to 140/90 mmHg NHS guidance suggests 90/60 to 120/80 ideal and above that could be at risk of developing High BP) |
| Systolic Bp 200 or above POSs causes: smoking, obesity, overweight, diabetes, sedentary lifestyle, not enough physical activity, Alcoa excess, insufficient calcium/magnesium/potassium, stress, age, vit d deficit, kidney disease, long term sleep depriv | |
| What can high BP cause? | Heart disease, heart attacks, vascular dementia, strokes, heart failure, peripheral arterial disease, aortic aneurysms, kidney disease, |
| Pressure in the thoracic vena cava before it joins right atrium. I.e essentially a measure of filling pressure for the preload of right ventricular which controls stroke volume. Norm 4-12 CmH20 | |
| What is capillary refill time? What is healthy time? | CRT is time taken for colour to return to external caplliary bed after pressure applied to cause blanching. Norm is Less than 2 seconds |
| Temperature Normal ranges | 36.1-38.0*c |
| What are normal urine output ranges? For 70kg adult? | 1ml/kg/phour So 70ml per hour |
| Anura is? | Cessation of urine output |
| Less than half a ml 0.5ml per kg per hour of urine passed | |
| Normal adult pass 1-2L of urine per day, polyuria is over 2l, some sources say 3l | |
| Oliguria is defined as? | |
| What is the term for excess urine passing? How many Litres? | |
| Renal function- how many mmol of urea is normal per litre? | 3-8mmol/litre |
| 50/120 umol/L | |
| What is the Glasgow coma scale? | Method of communicating levels of consciousness in patients with an acute head/ brain injury |
| What are the ranges for GCS-Eyes opening? | 4) spontaneously 3) to speech 2) to pain 1) no opening |
| What are the ranges for GCS-Verbal response? | 5) orientated 4) confused 3) inappropriate words 2) incomprehensible sounds 1) none |
| What are the ranges for GCS- Best Motor response? | 6) obeys commands 5) localises to pain 4) normal flexion 3) abnormal flexion 2) extension 1) none |
| AVPUC stands for? | Alert Verbal Pain Unresponsive concussed |
| Intercranial pressure normal ranges | ICP mmHg less than 10 |
| Cerebral perfusion pressure | Approx 70mmHg |
| Bloods -norms? 1)haemoglobin in men 2) in women | 130-180 g/l in men 115-165 women |
| WCC norms? | White cell count (10^9/L) 150-400 |
| Troponin levels | (ng/l) less than 10 |
| Lactate levels | Less than 2 normal 2-4 a bit of a problem, 4+ seriously high |
| NEWS stands for? What is normal value? | National early warning score 0-1 Standardised across NHS to prevent patient deterioration Based on 6 standardly measured areas: Pulse rate, BP, respiratory rate, o2 levels, temp, conscious level plus new confusion is added in the updated news2 |
