Q

What are the two classifications of respiration and what do they do?

A

External Respiration - the exchange of gases at alveolar and capillary level

Internal respiration - the metabolism of gases at a cellular level (where the body combines the oxygen with carbohydrates to create energy, resulting in C02 as a waste product)

Korotkoff.

described as a faint tapping, ticking or thudding sound

76
Q

What is advised when taking a pregnant patient’s BP?

A

When taking blood pressure it is advised that pregnant patients are sat up instead of lying down.

77
Q

What steps would you take when taking a patient’s BP?

A

1) Decontaminate hands, apply PPE if required and gain consent.
2) Select an arm and remove any clothing that is covering it, check for any broken skin, infections, mastectomy sites etc.
3) Check the equipment is in good order and clean/decontaminated.
4) Locate the brachial artery, wrap and fix the cuff securely 2-3cm above it.
5) Ensure the patient is rested, does not talk when taking and legs are uncrossed.
6) To calculate the estimated systolic pressure relocate the brachial artery and palpate while inflating the cuff. When the brachial artery can no longer be felt, inflate the cuff a further 20- 30 mmHg. Slowly deflate the cuff and note the point at which the pulse becomes detectable again. (this is the estimated systolic pressure)
7) Deflate the cuff and wait 15-30 seconds then lace the stethoscope in your ears (earbuds facing forward). and place the diaphragm over the brachial artery.
8) Inflate the cuff 20-30 mmHg above the estimated systolic pressure.
9) Slowly deflate the cuff by 2-3 mmHg per second. and listen for Korotkoff sounds. The first Korotkoff sound is the systolic reading and the diastolic reading is the point in which the sound completely disappears.
10) Once the Korotkoff sounds disappear, deflate the cuff and remove.
11) Decontaminate hands, remove PPE if applied and document the reading according to hospital/trust policy.
