| 영문 | blood gas | 한글 | 혈액가스, 혈액기체 |
|---|---|---|---|
| 설명 | 혈액 속에 용해되어 있는 산소, 이산화탄소, 질소 따위의 기체. 혈액의 산성-염기성의 정도를 측정할 수 있다. |

| 영문 | blood test | 한글 | 혈액검사 |
|---|---|---|---|
| 설명 | 혈액형이나 질병 유무 따위를 알기 위하여 피를 뽑아 행하는 검사. 몸 전체의 장기나 조직에 병터가 있으면 이들 성분에 변화가 있게 되어 진단에 큰 도움을 준다. |

| 영문 | blood-brain barrier | 한글 | 혈액뇌장벽 |
|---|---|---|---|
| 설명 | 혈액으로부터 뇌로는 지질용해성이 높은 약물밖에 이행되지 않는다. 수용성의 약물을 뇌로 이행되지 않게 하고 있는 것이 혈액뇌장벽이며 뇌의 모세혈관 내피세포, 모세혈관 주위의 세포가 장벽이 되고 있다. 물질교환은 수동확산에 의해 이루어지지만, 뇌의 생리적 활동에 필요한 물질은 이온형이라도 담체를 통해 이행된다. |

| 영문 | blood volume | 한글 | 혈액량 |
|---|---|---|---|
| 설명 | 체내에 존재하는 혈액의 총량으로서, 보통 리터 또는 체중 1kg에 대하여 리터수로 표시한다. |
||
| 영문 | blood urea nitrogen | 한글 | 혈액요소질소 |
|---|---|---|---|
| 설명 | 요소는 아미노산의 탈아미노에 의해 생긴 암노니아와 탄산가스로부터 간에서 합성된다. 혈중에서는 혈장과 혈구의 물성분 안에 함유되어 있다. 혈액요소질소는 콩팥토리에서 여과되며 일부 요세관에서 재흡수되고, 나머지가 오줌중에 배설된다. 따라서 혈액요소질소는 콩팥기능의 저하에 따라 증가되지만, 식사단백질 섭취량, 조직붕괴, 위장관 출혈 등과 탈수 등 순환혈액량의 이상으로 변동된다. |

| BlT | bleeding time; blood test; blood type, blood typing |
|---|---|
| CBL | circulating blood lymphocytes; chronic blood loss; cord blood leukocytes |
| DRBC | denaturated red blood cell; dog red blood cell; donkey red blood cell |
| EHBF | estimated hepatic blood flow; exercise hyperemia blood flow; extrahepatic blood flow |
| MBF | medullary blood flow; muscle blood flow; myocardial blood flow |
| cerebrospinal pressure | The pressure of the cerebrospinal fluid, normally 100 to 150 mm of water, relative to the ambient atmospheric pressure. (05 Mar 2000) |
|---|---|
| chromatography, high pressure liquid | Liquid chromatographic techniques which feature high inlet pressures, high sensitivity, and high speed. (12 Dec 1998) |
| root pressure | <botany> Pressure in the roots which, when the shoot is cut off, will cause liquid to ooze from the root stump, the mechanisms and tissues involved in this process are not clearly understood. (09 Oct 1997) |
| phrenic pressure test | Pressure is made on the phrenic nerve on each side, above the clavicles where the nerve passes over the scalenus anticus muscle; if pain is felt and the patient inclines his head to the painful side, the problem is in the pleural space; if his head does not incline to one side, the problem is in the abdominal cavity. (05 Mar 2000) |
| wedge pressure | The intravascular pressure reading obtained when a fine catheter is advanced until it completely occludes a small blood vessel or is sealed in place by inflation of a small cuff; commonly measured in the lung to estimate left atrial pressure. (05 Mar 2000) |
| pleural pressure | The pressure in the pleural space between the visceral and parietal pleurae. (05 Mar 2000) |
| continuous positive airway pressure | A technique of respiratory therapy, in either spontaneously breathing or mechanically ventilated patients, in which airway pressure is maintained above atmospheric pressure throughout the respiratory cycle by pressurization of the ventilatory circuit. (05 Mar 2000) |
| continuous positive pressure breathing | Artificial ventilation in which all inspirations are provided by positive pressure applied to the airway. Synonym: continuous positive pressure breathing, continuous positive pressure ventilation, intermittent positive pressure breathing, intermittent positive pressure ventilation. (05 Mar 2000) |
| continuous positive pressure ventilation | Synonym: controlled mechanical ventilation. (05 Mar 2000) |
| coronary perfusion pressure | The pressure at which blood proceeds through the coronary circulation, mainly in diastole. (05 Mar 2000) |
| portal pressure | The venous pressure measured in the portal vein. (12 Dec 1998) |
| positive end-expiratory pressure | A technique used in respiratory therapy in which airway pressure greater than atmospheric pressure is achieved at the end of exhalation by introduction of a mechanical impedance to exhalation. (05 Mar 2000) |
| positive-negative pressure breathing | Inflation of the lungs with positive pressure and deflation with negative pressure by an automatic ventilator. (05 Mar 2000) |
| positive-pressure respiration | A method of mechanical ventilation in which pressure is maintained to increase the volume of gas remaining in the lungs at the end of expiration, thus reducing the shunting of blood through the lungs and improving gas exchange. (12 Dec 1998) |
| positive-pressure respiration, intrinsic | Non-therapeutic positive end-expiratory pressure occurring frequently in patients with severe airway obstruction. It can appear with or without the administration of external positive end-expiratory pressure (positive-pressure respiration). It presents an important load on the inspiratory muscles which are operating at a mechanical disadvantage due to hyperinflation. Auto-peep may cause profound hypotension that should be treated by intravascular volume expansion, increasing the time for expiration, and/or changing from assist mode to intermittent mandatory ventilation mode.
